Planet Money - When our inflation infeelings don’t match the CPI

Episode Date: August 15, 2025

For most Americans, we just lived through the highest period of inflation in our lives. And we are reminded of this every time we go grocery shopping. All over TikTok, tons of people have posted videos of how little they got for … $20. $40. $100. Most upsetting to us: an $8 box of Cinnamon Toast Crunch.Food prices are almost 30% higher than they were five years ago. It’s bad. And those new, higher prices aren’t going away.At the same time, prices are no longer inflating at a wild pace. For the last two years, the rate of inflation has slowed way down. And yet, our fears or feelings that things will spiral out of control again? Those have not slowed down.This mismatch has been giving us all the …. feelings. Inflation feelings. Infeelings. On our latest show: we sort through our infeeltions. We talk to the economists who have studied us. We learn why our personal inflation calculators don’t always match the professional ones.Listen free at these links: Apple Podcasts, Spotify, the NPR app or anywhere you get podcasts.Find more Planet Money: Facebook / Instagram / TikTok / Our weekly Newsletter.Support Planet Money, get bonus episodes and sponsor-free listening and now Summer School episodes one week early by subscribing to Planet Money+ in Apple Podcasts or at plus.npr.org/planetmoney.Learn more about sponsor message choices: podcastchoices.com/adchoicesNPR Privacy Policy

This is Planet Money from NPR. What drove the young man named Rocky to the cinnamon toast crunch that day? His inner child, perhaps, memories of Saturday mornings and cartoons and pajamas, maybe, but there he was in the cereal aisle, holding a box of cinnamon toast crunch and losing his mind. Okay, y'all, I might be an unc for real, because since when is cereal? $8 a box? What the hell? Rocky turned to TikTok to sort of work through his feelings about this apparent serial inflation. Like, am I tripping?

He's addressing a friend here. Gee, am I tripping? Has cereal always been this high? I guess. I don't know. Okay, he acting like as normal. Maybe I'm just broken. Inflation has been and continues to be one of the single biggest economic concerns for Americans, according to a regular survey from Gallup. And that anxiety is very easy to understand. People are worried about the impact of tariffs. There are rumblings of possible inflation upticks to come. And maybe most obviously,

prices are indeed way up compared to before the pandemic. Like groceries are 30% more expensive than they were just like five or so years ago. And look, those prices are not going to come down. That is simply not how inflation works. We always have some. inflation, prices go up. The question is, at what rate do those prices go up? And two years ago, the rate of inflation did come way down. It's been decently close to the target inflation rate of 2% for a couple years now. So inflation has cooled a lot, but you know it has not cooled off? TikToks like Rockies, which I have come to love and call the, I'm sorry, groceries cost what now? social media post.

The basic structure of one of these goes, Holy cow, I just got back from Target. Person goes to the grocery store. Went to Sam's Club for four items. Often buys 20 items or less. Two bags of groceries. Three items at a small town grocery store. These are notably not unusual items.

Bananas. Some chips of hoy. Case of Diet Coke. Some peppers. A bag of pizza rolls. Just like basic things. But you know what? When they go to checkout, I'm sorry, these groceries

costs what now? $20. These are five items. Six items, $88. Four items, $101. What the f***? The rate that we're going right now, next week, these four items

will likely be $120. I'm serious. I'm not joking. Now, that would be 20% inflation, and I very much understand this fear, because for the majority of Americans, we just lived through the highest period of inflation in our lives, and we're reminding

of this every time we go to the grocery store, and we see what this period of inflation did to the price of our Diet Coke and our pizza rolls. And for our TikTok friend, Rocky, his cinnamon toast crunch. Like, I'm almost positive that cereal was never almost $10 a box. It's true. I, too, have nearly crashed my buggy, specifically because the prices of cereal stunned me. I get this. And yet, it is my job to know the inflation data. And the official inflation statistics say that the price of groceries over the last year has increased 2.2 percent, like not ideal, but not the 20 percent inflation. It may feel like we should expect. And I think there is something mysterious about the way we experience the mix of these dramatically

higher prices and the not as dramatic inflation that we're in the middle of right now. We're not wrong. The data's not wrong. But maybe we can take a lesson from TikTok Rocky, who, when confronted with the proverbial $8 box of cinnamon toast crunch, had the instinct to just try and talk through those inflation feelings. Hello and welcome to Planet Money. I'm Kenny Malone. And I'm Jeff Guo.

Inflation. Feelings. Infeelings? Yeah, sure. Okay. Economists have been studying our in feelings. Because when there is a mismatch between inflation. and our perceptions of inflation, it matters.

It changes our behavior. It affects who we vote for, what we buy, when we buy it, which mortgages we take out, all sorts of choices we make. And so today on the show, we talk to the economists who have studied us and hear what they've learned about why our sort of personal inflation calculators don't always match the professional ones. So grab a spoon and a bowl and some dang expensive cinnamon toast crunch and see if we can all work through some infeotions together.

There is a lot of good research on the ways our brains process changing prices. But before we started calling the economist names on those research papers, a more important phone call. Is this Rocky? Hey, yeah, what's up, Danny? Rocky Walker, 27 years old, security guard, day, TikTok creator by night at Rocky Rare. Rocky tells us that on the fateful day of his $8 cereal video, he did not enter the grocery store intending to talk about cinnamon toast crunch.

It's been up forever since I've really sat down and just had a bowl of cereal and watched some part tunnel. So you really were looking for that nostalgia bump? Literally just, yeah, I haven't bought some cinnamon toast crunch in a hot minute, but... Did you end up buying that cinnamon toast crunch for $8? Hell no. I put it back. Held off. Rocky is not typically tick-talking about economics, but if you are documenting your life these

days, prices and money and economics, they're just all part of that. I mean, with everything, like, say for instance, not even with just groceries, I feel like what my generation are, like, Gen Z, like, we're the new adults, quote, unquote, but it's just What do you mean, quote unquote? Are you not, do you not feel like you're an adult? I mean, you know, we're all at her for a first time, really just try to swim, but with these prices, it's so, like, it's so hard to try to, like, budget between fun, between, like, responsibilities and just like necessity and like feel like it's not like a lot of weight on your shoulders because this stuff is not cheap at all yeah because inflation is cumulative it adds up

overall prices are still about 25 percent higher than they were five years ago and these new higher prices aren't going away now those prices are no longer going up at a wild pace the rate of inflation has slowed way down by comparison but our fears are our are feelings that things will spiral out of control again. For some of us, for me personally, I'm not sure that has slowed down. We told Rocky that his TikTok had helped inspire us to talk through our inflation feelings with the economists who have been studying this stuff, writing papers about it. Along the way, would it be okay if I shared some of the things I've learned

like from the economists I've talked to and some of the papers that we've been reading? Would that be cool? Of course. I love getting informed, man. Okay, so we will check back. in with Rocky from time to time. But that thing he said about his generation feeling this inflationary weight on their shoulders reminded us about some very specific research about how different generations react to price increases. Because living through inflation can leave a kind of economic scar that has a big impact on our in feelings. To talk about that research,

we turn to one of the authors, an economist who thinks of her own inflation anxieties as a kind of heritage. I'm German, and definitely the general anxiety of the Germans about inflation at all times has been transmitted to me, and I don't think I will ever get rid of it. Ulrika Malmendir is a finance and economics professor at UC Berkeley, and indeed from Germany, which had bonkers inflation in the 1920s, wheelbarrows full of German marks, more valuable as bonfire kind of stuff. So yes, she jokes that she has inherited disproportionate inflation anxiety. But her research has specifically looked at what happens when someone actually lives through periods of high inflation. The main emphasis of that research can be typically boiled down

to saying, well, give me your birth year. And I get a very good idea of how optimistic or pessimistic you are about inflation. Yeah, depending on where you live. So let's say you lived in the United States during that huge double-digit inflation of the 1970s and 80s, O'Rika found that this scars people. It makes them more likely to expect inflation in the future, no matter who they are. Even the best informed people who are, I don't know, serving on the Fed board, even these people we've been able to show tend to put a lot of weight on experiences they have had themselves. But what I was curious about were the more recent generation. Because, you know, for example, I'm 40, our friend Rocky is 27, and neither of us has really

seen or thought about inflation until the relatively brief spike around COVID. Yeah. So where you are going is also really interesting because you have had very stable inflation experience much of your life. That was your world. You know, if you studied economics, you knew about inflation from textbooks. It was theory. It was totally theory for me.

Exactly. That was just theory. And suddenly, your world gets turned upside down. People in these younger generations grew up taking for granted that inflation was always low and stable. And then when inflation rates spiked in the early 2020s, it was extra disorienting. It really shocks you so much because you can't even handle that data. And that's what we are seeing in the kind of younger generation, your age, but particularly, Even younger, that's when, you know, you don't know how to move forward, where basically you keep trying to process it and you can't fully process it so you do these cool TikTok videos about cinnamon crunch toast, which is, of course, a great cereal. Oh, O'Rika knows.

I mean, she knows about cinnamon toast crunch being the greatest cereal of all time, but also why the price of cinnamon toast crunch might have a particularly outsized effect on our assessment of inflation. Yes. This brings us to the second major area of Ulrika's research that we want to talk about. And it has to do with the way that we, as individuals, perceive inflation versus the way economists measure inflation. So just to step back for a second, you may be familiar with the Consumer Price Index, CPI. This is like the main measure of inflation from the Bureau of Labor Statistics. And the way this is calculated is they have this massive list of things that we pay for. They monitor the changes in those prices.

And then they blend that all up into a single measurement, CPI, which tells us things are getting this much more expensive. That is inflation. It's meant to capture all of the price changes affecting everybody in the country in one single measurement. Now, what Ulrika has found is that we consumers are each doing a version of this for ourselves. But the list of items that we monitor, it is very small. It's really just the stuff that we look at and we buy all the time. Hence, all this emphasis on the gas pump, right? And then groceries.

And we found, you know, people think a lot about bread, milk, eggs. Men, also beer. Beer prices matter. Men, beer prices. Why not? Yeah. Each of us has our own version of frequently bought items that we really notice price changes in. TikTok Rocky, for example, really watching.

the prices of chips. Anywhere from the lays to the Doritos. Also, meat? Mind you, I don't even eat beef or pork anymore, but... But chicken, salmon, and watching most of all eggs. Rocky loves breakfast, loves baking. Eggs definitely is one of the things that I'm going to have to buy no matter what. No matter what.

And I do want to know your number one bake. Like, someone's coming over to your house for the first time, you want to impress them. That would involve eggs. I would definitely, like, everyone loves mac and cheese. Like, I would like to cook for my friends. So I would definitely make them some baked mac and cheese, like some soul food, for sure. So Rocky may not realize it, but Ulrika's research would suggest that he is likely getting a big chunk of his take on inflation from the prices of chips and chicken and eggs because he is buying those things frequently. And all of us do a version of this.

And Al Rika says that can mislead us. For starters, frequently bought grocery items, they don't actually. actually make up that big of a chunk of our total spending. When you think about all the huge things that we also spend money on, like housing and child care. Also, food prices happen to be some of the most notoriously unreliable prices to watch, which Rocky has noticed with regards to his beloved eggs. But yeah, like, that's one thing that always kind of, like, gags me a little bit because

sometimes it'll be like $2, which is like the normal price, and sometimes it'll go up all the way to like six or seven for like a dozen, which is crazy. Yeah, food prices and gas prices, too, they jump all over the place up and down for reasons that may not be signs of overall inflation because inflation, by definition, is a rise in prices all across the economy. As opposed to a situation where, say, bird flu messes up the egg supply or OPEC cuts oil production or a natural disaster devastates a corn crop, those may just be tempered. In a specific sector, that may go back to normal.

And the irony of it all is that as a researcher and as a monetary policymaker, you are always pushed and asked not to look at exactly those items, energy and groceries because they fluctuates so much. But we, humans, that's basically all we look at all the time when you think about inflation. There is a different inflation calculation that you may have heard of. of that takes out volatile things like energy and food. It is called core CPI, core inflation, and it is something policymakers will look at to get a sense of overall inflation trends without the noisiness of those volatile price swings

that we're talking about. And there's one final thing about volatile prices, which is that other research has shown that we really notice when prices swing up, but we don't notice as much when they swing down. People really seem to latch on to the up part and get totally upset about it. And then on the down part, they're like, whatever. You know, they're not kind of spending as much emotional capital on it.

Well, Rocky is not going to make a TikTok when Cinnamon Toast Crunch is on sale for $5. Oh, perfect. I have to remember that anecdote going forward. Now, look, going to the grocery store, it's not going to be an anxiety-free activity anytime soon. Everything we buy really is more expensive than it used to be. And while the data show that the median income has generally kept up with that inflation, it doesn't mean that everyone is benefiting from those increasing salaries. But it is also true that there might be, might be,

some additional stress we do not have to bring to those grocery store trips. Like the fact that we instinctively look at just a few grocery items to gauge all of inflation and the fact that we latch on to the volatile ups of price swings but not the volatile down, it does create a situation where we may be stressing over sudden grocery price jumps a little bit more than we have to. So what are we grocery shoppers supposed to do about these volatile prices playing tricks on our minds? Well, we asked Orika, and she says it sort of boils down to, could you find ways to blunt the ups and downs of those groceries, that volatility that isn't actually inflation? So if I could convince grocery shops to kind of average out prices, so take out some of these fluctuations, or I could convince you not to look at the price. Yeah, it's like the classic advice you hear about the stock market, right?

Don't look at the ups and downs of your retirement account every single day. Just look once a year at the end of the year and focus on the general trend. You could possibly try the same thing with your groceries, I suppose. Like, just buy what's on your list and don't look at how the prices are jumping up and down and up and down. And then at the end of the year, we look back and say, okay, on average, wasn't so bad. So I don't need to get all nervous about. So if I could do that, I would love that. You know, that's an idea.

In theory, that would make sense, yes, I guess. And we did run that idea past Rocky. What do you think about that idea? Just close your eyes and buy the things. Um, I don't. I mean, I don't know. Like, I guess I can, like, understand the, like, the setup is just, I don't know if that would. You know, like, I don't know if that would work for me just because, you know.

I do know. With everything going on, like, you kind of have to go into things like grocery shopping with a game plan. Because, like, say, for instance, if there's some things that you know might go and sell later, you might, like, hold off on that or make that stretch a little bit until, you know, you can get it at a decent price. So I don't think that would work for me. Yeah, it's not going to work for Rocky. Or probably most of us. It is very difficult to ignore the prices that we see all the time. But we can remember Oval Rica's research that we may be putting too much emphasis on too few things

or on things that change in price all the time and may not be an indication that overall inflation is actually on the rise again. After the break, we look at maybe the single most important. important thing we measure for inflation. And why those measures, too, are sometimes hard to believe. $8.00 cinnamon toast crunch. Obviously, my favorite TikTok by Rocky Walker. A close second, though, is this. Picture this. Rocky is sitting in his apartment, which is maybe seven stories up in his Chicago apartment building. And some just told me to turn around and look out the balcony. And look what I see.

The camera flips around and we see snow on the balcony. We see a couple bikes on the balcony, but also perched there on the railing. Hello there. What's up, buddy? It is the fluffiest little bird you will ever see. It kind of looked like a baby like hawk or eagle. So fluffy, though. Oh, my God.

I would try to give it some food, but I feel like if I open the door, it's going to fly away. But, I mean, you're free to chill there as long as you want, buddy. I would watch that channel 24-7. That's all I'm saying. But, but relevant to this episode is that when I talked to Rocky, he told me he was currently looking to move out of that bird balcony apartment. And he's been very surprised at the prices he is seeing to rent apartments.

Rent is crazy. I haven't moved in five years, and the difference between prices when I moved five years ago and now is insane. Yes, the price of rent. It is arguably, arguably, more noteworthy than the price of cinnamon toast crunch.

Like a one-bedroom, one bathroom here in Chicago, you could very much find something within like the 1,000 range. To now, we're like, they're very much asking for a good $1,500 or above to be in a decent neighborhood with decent appliance, and something that doesn't look ancient. And I feel like that's crazy. The average price of rent is about 29% higher today than before the pandemic.

And how much we pay to live where we live is one of the single biggest things that goes into the consumer price index. It's like a third of the total weight. The term you'll hear for this is housing services. And that housing services bucket in particular is an area that produces a lot of in feelings and also produces some pretty interesting conundrums for economists when they are trying to measure inflation. Test one, two. We brought economist Louise Schener into the studio to talk about all of this.

Have you had any dreams of mic checks you've ever wanted to do? No, I'm sorry. Mykechick, one, two, three. Brookings in the house. Brookings in the house. See, that one's good. That's good, yeah. Louise is a senior fellow at the Brookings Institution.

She's done a lot of work around housing prices and how those prices are factored into inflation data. Now, we asked Louise to get extra nerdy with us and explain how the numbers are collected and calculated. And Louise said, A, of course, she would do that for us. And then B, that we should start perhaps with how we get the cost of housing for renters like Rocky. It's pretty simple. It's your rent, right? How much you're spending? You're spending rent.

What happened to rent? It's very simple. No real issue there. That's pretty easy to measure. You could call me and ask me what my rent is. Exactly. Okay. All right.

So that's easy. The data is easy to collect. More or less, you go around asking people what they pay in rent. And the people who track inflation for the consumer price index, they're contacting all kinds of renters, people who just moved into a place, people who have lived in the same place for five years or 20 years or 40 years. And this is a very reasonable way to calculate overall rent prices for inflation. Because CPI is trying to measure the cost of rent for everybody. But the thing is, if you are like Rocky and looking for a new place, it doesn't matter what people are paying for rent if they've lived in the same place for 20 or 40 years and aren't moving. Like, those are not the kinds of rent prices that Rocky is going to find if he's looking for a new apartment on, let's say, Zillow.

Yeah, and generally speaking, those live market rate rental prices for places that are available right now, they can change a lot faster. Yeah, way faster, man. It's really crazy. Definitely faster than what is reflected in the CPI. Yeah, so there can be this disconnect between what you might see for market rates on Zillow and then the measurements the Bureau of Labor Statistics, BLS, takes. And that disconnect created a whole thing during COVID, Louise says. Because rental index is using big data, like the Zillow Rent Index, was showing much bigger increases than what BLS was showing. on their rent index. And so people would look at the official CPI numbers and be like, wait, what?

Those official numbers seem too low. But the reality is CPI is simply a slower, laggier indicator, in part because it's not just looking at those new market level listings on Zillow. Just to give you a sense of this lag, after the pandemic, it took official inflation numbers, like a year longer than Zillow numbers, to show that rents. rent increases had finally started to slow down. This is simply how it works with the CPI and rentals. Yep.

And, okay, things get even trickier when we try to measure inflation for homes people own, which makes up an even bigger portion of the CPI than just rentals. The majority of people, like two-thirds, live in homes they or their family own. And Louise says it is deceptively tricky to calculate what homeowners are paying for their version of housing services. The hard thing is when people own their homes. They are not writing a check for housing services. Okay. Well, they're writing a mortgage check.

They might be writing a mortgage check unless they've fully paid off their mortgage. Their mortgage check will depend on how big their down payment was. Their mortgage check will depend on when did you take out your mortgage? And so you cannot just call people up and ask how much is your monthly mortgage payment because that would drag all of those other variables into the equation. And so you hear the word owner's equivalent rent. Owners equivalent rent. O-E-R.

O-E-R. O-E-R. Do we try to pronounce it, O-E-R? No, we say O-E-R. Okay. So, to measure inflation when it comes to homeowners, there is this clever little trick. The idea is that you look at some owner-occupied house and then calculate what would likely be the rental-penter,

price for that home. How much rent could you rent your house out for? Oh. That's what it is. What is the opportunity cost of me staying in this house? As opposed to renting it to somebody else. So I'm renting it to myself, this is how much I'm paying. Well, great. That's not complicated. It's not complicated. We're done. Well, how do you get that? Ah, yes. Well, what the statistics people do is go looking for similar houses that are available to rent, which is clever, but perhaps comes with some tradeoffs. Because quite literally, this means our official inflation statistics use the experience of home renters to stand in for the experience of home owners. Yeah. So one issue is that generally speaking, there just aren't as many rental versions of houses on the market. The

rental homes that are on the market, how equivalent really are they to the houses that people own, right? That is always a question. Yeah. And then question or I guess issue number two is that this OER is also a lagging indicator because just like rental prices, OER is made up of the same rental price information ultimately. So again, any big sudden swings, it's going to take time for the official statistics to catch up. But look, there is no perfect solution to measuring the experience of inflation for homeowners. And, in fact, there isn't agreement across countries on how to measure housing services. Some people in the European Consumer Price Index, they don't include unoccupied.

They just take it out because it's too complicated to measure. That's the like, yeah, that's the slackers solution. Well, so here's where. I don't know. It's too hard. There are a lot of people trying to think about, well, how. could you use Zillow and house prices and big data and, like, is there a way of doing a bit better? But nothing yet.

And the thing is, whenever we try to measure things and then process that down into a useful amount of information, there are going to be tradeoffs. If you wanted a housing inflation number that people could look at and feel reflects their personal experience, well, you might need a different number for long-term renters versus new renters versus homeowners versus people looking to. buy their first home versus people looking to sell their home. Each of those groups could look at the current inflation data and feel like, wait, does that number actually capture what I'm feeling about housing inflation right now? Do you have a sense of whether we've chosen an approach that is more about capturing the feeling versus whatever the alternative would be? I think we've chosen an approach that is economically sensible.

Like, I was on a National Academy of Science Panel, and we voted on webinar. We thought the current method was kind of right. Amazing. But it was all economists, and we said yes. Oh, okay. Okay. So I think we recognize that it doesn't necessarily capture people's feelings. And people's feelings are very important. So there is something about a CPI that is on his face wrong because everybody has a different CPI. What are you buying? What do you care about? How much is this quality improvement worth to you? we have to get a number that kind of gets it right on average. But there's a million things happening underneath and we have this one summary statistics.

Economists and policymakers, they need those summary statistics to understand how the economy is doing overall, how much we need to worry about inflation, you know, as a country. That is important. But as Louise said, our individual experiences are also important, our infealtions. And so we knew we did need to. check-in one more time on the infelions that started this whole episode to begin with. Rocky. Hey, what's up, Kenny?

Are you at the grocery store? Yeah, I'm walking in right now. We wanted the most recent update on the very personalized TikTok Rocky price index. Yeah, the TRPI. And so we asked him to go back to the grocery store and to, you know, reprice a few items for us. Rocky's first stop, the chip aisle, one of his frequently bought and priced. items. I'm looking at the Doritos. So regularly, they're 6.30. But they have a deal for like two bags for $7. So pretty much $3.50 each. Okay. But yeah, I'm not going to like, that's an instant grab.

Okay. For sure. That's one that I can't pass up. Okay, great. But keep going, Rocky. Keep going. Because the real reason we're here, the cinnamon toast crunch, of course. Surprisingly, they're on sale right now. Oh, really? Yeah, they're on sale right now. What's the price? So they're on sale for like $6.00. 50 cent, but they have like a deal where like if you buy for it, you get them for $2 each. What? What? Yeah. That's crazy. I mean, Rocky, how many boxes of Cinnamon Toast Crunchery are we buying? Six, nine? This is stockpile time, man.

Rocky takes a moment, considers all of this. If you want my honest, honest reason why that I'm like skeptical about it is because four boxes of cinnamon toast crunch, that's going to be like just staring there at the top of the refrigerator heavy. That is a lot. I mean, right here, it is kind of a lot. You're doing some preventative willpower work here. Yeah, you, you, if you feel me, because literally having four boxes of sugar just. All right. Yeah. Fair enough, Rocky. Fair enough. Before we go, a quick shout out to our Planet Money Plus listeners. Your support helps keep NPR going. And as a thank you for that support.
