There are several, each measured a different way, and they often disagree. This page puts them on one chart so you can see where they disagree and why it matters. ## Latest reading Inflation is *3.3%* Prices are 3.3% higher than they were a year ago. Leave out food and energy, which jump around a lot, and the rise is 2.5%. The measure the Fed watches most closely says 3.3%. The Fed is aiming for about 2%.

You can show up to 5 lines at once, and picking a sixth drops whichever you chose first. No figures were collected for October 2025. The solid line stops there and a faint dashed one carries across, so you can follow the shape without us inventing a reading. Lines you can draw ### The headline numbers What people mean when they say inflation is 3 percent. - Headline CPI Everything a normal household buys: food, rent, fuel, haircuts. - Headline PCE A wider measure than CPI. This is the one the Fed's 2 percent goal is set on. ### With the noisy bits removed The same shopping list, minus the prices that jump around most. - Core CPI The same list with food and energy taken out, because those two jump around. - Core PCE The Fed's measure with food and energy taken out. The number it leans on most. - Supercore CPI Services like haircuts and repairs, with housing and energy taken out. No official version exists, so we build it. - Supercore PCE The same idea, measured on the Fed's wider list. This one is official. - Core services CPI Everything people do for you rather than sell you, minus household energy. - Core goods CPI Physical things you buy, minus food and energy. - CPI services less rent of shelter Services with anything housing-related taken out. ### Built to ignore the odd ones out Different ways of ignoring whichever prices went wild this month. - Median CPI The one price change sitting exactly in the middle. One wild category cannot shift it. - 16% trimmed-mean CPI Crosses off the biggest risers and the biggest fallers, then averages the rest. - Trimmed-mean PCE The same idea, applied to the Fed's wider list. - Sticky-price core CPI Only the prices that change slowly, like insurance. These say more about what comes next. - Flexible-price core CPI Only the prices that change fast, like petrol. Jumpy by design. - Sticky CPI less food, energy and shelter Close to supercore in spirit, and it goes back much further. ### Individual prices The separate things in the shopping list, so you can see what is doing the work. 18 to choose from. Housing 3 - Shelter Rent, plus what owners would pay to rent their own home. - Owners' equivalent rent What a homeowner would pay to rent their own place. The biggest single item, and the slowest to move. - Rent What renters actually pay, including people part-way through a lease. Food 2 - Groceries Groceries. - Eating out Restaurants and takeaway. Energy 4 - Petrol and heating oil Petrol and heating oil. - Gas and electricity Electricity and piped gas. - Gasoline The price most people notice first. - Electricity Your electricity bill. Getting around 5 - Getting around Car repairs, insurance, and fares. - New cars The price of a brand new car. - Second-hand cars The item that drove the 2021 price spike. - Car insurance A small item that rose sharply for several years. - Plane tickets A tiny slice of spending that swings wildly. Health and clothes 2 - Medical care Doctors, dentists, hospitals and health insurance. - Clothes and shoes Clothing, footwear and the like. The two halves of the basket 2 - All services Everything people do for you rather than sell you. - All goods Every physical thing you buy, food and fuel included. ### What comes next Not what prices did. What they are expected to do. - Expected inflation, 1 year A forecast of what inflation will be over the next year. - Expected inflation, 10 years The same forecast, but looking ten years out. - 5-year breakeven What investors are betting inflation will average over the next five years. - 10-year breakeven The same bet, over ten years instead of five. - 5-year, 5-year forward What investors expect for the five years starting five years from now. The Fed watches this one. ## What is actually pushing it up Split the whole shopping list into four parts. The numbers below show how much of the last year of inflation each part is responsible for. They are in percentage points, so if inflation is 3 percent and housing shows 1.1, housing accounts for 1.1 of those 3 points. A minus number means that part pulled inflation down instead. - Housing +1.12 - Services, not housing +0.70 - Goods +0.15 - Food and energy +1.33 The four parts add up to +3.30 points, against inflation of 3.3%. A part matters for two reasons: how much its own price moved, and how big a slice of your spending it is. Housing is about a third of the whole list, so it dominates this picture even in a quiet year. Something small like plane tickets can double in price and still barely register here. ## Every measure, side by side Every measure, at the same moment, over four different lengths of time. The left column is the one people quote. The shorter columns pick up a change sooner, but they are also jumpier. A measure that looks calm over a year can already be moving in the last three months, and that is often the first hint that something has turned.

The measures below work differently. They line every price up by how far it moved this month, then cut off both ends of that line. Cutting the ends off is what "trimming" means. The list of what gets cut is rebuilt every month, and nothing is banned for good. - ### Core CPI, for contrast The familiar one, and the odd one out on this list. It does not look at what prices did at all. It removes the same two groups every single month, by name. Throws awayFood and energy, always, whether or not they were the odd ones out that month. Good forA quick steadier read that everyone quotes. The rest of this list exists because "always the same two" is a rough rule. - ### Median CPI Rank every price in the basket by how much it moved this month, weighted by how much people actually spend on it. Keep the single one sitting at the halfway point. Throws awayEverything on both sides of the middle. It keeps one reading and discards the rest. Good forThe steadiest line on this page. One category going wild can barely move it. - ### 16% trimmed-mean CPI The same ranking, but it keeps the whole middle of the pack and averages it instead of keeping one point. It is built from 45 spending groups. Throws awayThe bottom 8 percent and the top 8 percent, measured by share of spending rather than by counting items. That leaves 84 percent of the basket. Good forCalmer than core, while still using most of what households buy. - ### Trimmed-mean PCE The same idea applied to the wider basket, the one the 2 percent goal is written on. Throws away24 percent off the bottom and 31 percent off the top, by share of spending, leaving 45 percent. The two ends are deliberately different sizes: that split was chosen by testing which one tracked the underlying trend best. Good forJudging the trend on the same basket the target is set on. - ### Sticky-price core CPI Not a trim. It sorts the basket by how OFTEN each price changes, then keeps only the slow half. Food and energy come out as well. Throws awayAnything whose price changes more often than once every 4.3 months. Good forA shop that only reprices once a year has to guess at future inflation when it does. That guess is what this measure picks up. - ### Flexible-price core CPI The other half of that same sort: only the prices that change often, again without food and energy. Throws awayAnything whose price changes less often than once every 4.3 months. Good forSeeing what is reacting to the economy right now. It turns early and it is jumpy. Sticky and flexible are the odd ones out here. The trims ask how far a price moved THIS month, so what gets cut changes every time. The sticky split asks how often a price changes at all, which is a settled fact about the item. Petrol is always flexible, even in a quiet month. ### Which prices count as slow, and which as fast The number is how many months typically pass between one price change and the next. Anything slower than 4.3 months counts as slow. SLOW TO CHANGEMONTHS FAST TO CHANGEMONTHS Eating out10.7 Petrol0.7Rent11.0 Fresh fruit and veg1.3Education11.1 Gas and electricity1.6Medical care14.0 Meat, fish and eggs1.9Car insurance5.9 New cars2.0Haircuts and salons23.7 Hotels3.1 Can you see which items got cut? For the wider basket, yes: the month’s included and excluded list is published as a spreadsheet every release. For the CPI trims only the rule is published, not the monthly casualty list. Either way the pattern is the same, and things with famously jumpy prices land in the cut ends far more often than something steady like rent. So why not just drop food and energy every time? Because a fixed list quietly claims two things: that the removed items are always noise, and that everything kept is always signal. Neither is true. A one-off jump in something you kept, like a tax rise on tobacco, goes straight into the number, where a trim would have thrown it out. ## What each one actually means Short answers, no jargon. You do not need any of this to read the chart, but it is here when a name on the list makes no sense. ### Why there are so many numbers There is no single true inflation number. Each one is measured a different way, and each answers a different question. Some tell you what your bills actually did. Others try to tell you where prices are going next. When two of them disagree, that gap is the interesting bit. ### What CPI is CPI follows the price of the things a normal household buys. Food, rent, petrol, a haircut, a bus fare. Every month thousands of these prices get checked, and the result is how much the whole shopping list moved. When the news says inflation is 3 percent, this is usually the number they mean. ### Why food and energy get taken out Food and energy prices jump around for reasons nobody controls. Petrol, heating, electricity, and the weekly shop. A cold winter, a bad harvest, a war a long way away. Take those two out and you get a calmer number that is easier to read. That is core inflation. It is not your cost of living, because you still pay those bills. It is a signal, not a receipt. ### Core is a blunt tool Core takes out the same two things every single month, whether or not they were the odd ones out. Plenty of other prices swing about too. Plane tickets, second-hand cars, car insurance. Core leaves all of those in. That is why the other measures below exist. ### What trimming means Picture every price on the list lined up, from the biggest fall to the biggest rise. Trimming means crossing off the extremes at both ends and averaging what is left in the middle. The items you cross off change every month. One month it is eggs. The next it is plane tickets. ### The median is the strictest version The median goes further. It throws away everything except the one price change sitting exactly in the middle of the line-up. It is the steadiest number on this page. It also tends to sit a little above the main figure, so judge it against its own past rather than straight against 2 percent. ### Why the Fed uses PCE and not CPI The Fed’s 2 percent goal is set on a different measure, called PCE. Two things make it different. It lets your shopping list change when you change it: if beef gets expensive and you buy chicken instead, PCE notices. And it counts medical care paid for by insurers and government, not only what you hand over at the counter. ### Where the gap between CPI and PCE comes from Mostly housing. Housing is about a third of the CPI list and a much smaller slice of PCE. So when rents move, CPI moves a lot more. Medical care pulls the other way, because PCE counts the bills your insurer pays and CPI does not. ### Why the housing number is always behind Most renters sign up for a year, and their rent cannot change until that year is up. So when rents in the real world start rising or falling, it takes a long time to show up in the figures. Roughly a year behind, sometimes longer. If the housing line looks stuck, that is usually why. ### Slow prices and fast prices Some prices change almost daily, like petrol. Others change about once a year, like your insurance. Splitting them apart is useful. The slow ones tend to show what businesses expect to happen next. The fast ones just react to what is happening right now. ### What supercore is for Supercore is services with housing and energy taken out. Think haircuts, restaurants, repairs, childcare. People watch it because wages are the biggest cost of those things, so it should show whether pay rises are pushing prices up. It caught on after a Fed speech in late 2022. Since then the link to the jobs market has looked weaker than people hoped. ### A year, or the last few months Year over year compares this month with the same month a year ago. That is what most people mean by inflation. It is also a twelve-month window, so it is always partly a story about last year. The shorter windows turn faster. They are noisier too, so one strange month can mislead you. ### What "at an annual rate" means The short windows answer one question: if the last few months carried on like that for a whole year, where would inflation end up? It puts a three-month figure and a yearly figure on the same scale so you can compare them. It also blows up one odd month into a big-looking number, so treat a jumpy short window with care. ## The numbers View the chart as a data table Latest 24 months, percent MONTHCPICORE CPICORE PCE Jul 20263.32.53.3Jun 20263.52.63.3May 20264.22.83.5Apr 20263.82.73.3Mar 20263.32.63.3Feb 20262.42.53.0Jan 20262.42.53.1Dec 20252.72.63.0Nov 20252.72.62.8Oct 2025--2.8Sep 20253.03.02.8Aug 20252.93.12.9Jul 20252.73.12.9Jun 20252.72.92.8May 20252.42.82.8Apr 20252.32.82.6Mar 20252.42.82.7Feb 20252.83.13.0Jan 20253.03.32.8Dec 20242.93.23.0Nov 20242.73.33.0Oct 20242.63.33.0Sep 20242.43.32.8Aug 20242.63.32.9 This page shows the last ten years.

[Get the data through the API →](https://helious.io/developers/) ## How this page is built **Every number is measured the same way.** Prices follow a seasonal pattern. Coats cost more in autumn, flights cost more in August. All the figures here have that pattern smoothed out, including the yearly ones. The official yearly figure quoted in the news does not smooth it, so our yearly number can sit a fraction away from the one you read elsewhere. We do it this way so that all four window buttons agree with each other. **Supercore CPI is our own calculation.** Nobody publishes an official one. We work it out from two wider measures that are published, and it starts in 2012 because that is as far back as the information we need goes. Supercore PCE is different: that one is official, and we do not change it. **A gap means a gap.** If nobody collected the prices for a month, the line breaks. We would rather show you the hole than draw a straight line across it and pretend we know. **Numbers change later.** Inflation figures get corrected after they first come out. This page follows the corrections instead of freezing the first version, so a number here can move. That is normal, and it happens to every measure on this page. ## FAQ ### What is the difference between CPI and PCE? They measure different shopping lists. CPI counts what households pay out of their own pockets, and keeps the list fairly fixed. PCE counts a wider set of spending, including medical care paid for by insurers and government, and it lets the list change as people switch what they buy. Housing counts for much more in CPI, and that is where most of the gap between the two comes from. ### Which inflation number does the Federal Reserve actually target? The 2 percent goal is set on the yearly change in headline PCE, looked at over the long run. Not core, not CPI, and not any single month. In practice the Fed also watches core PCE closely, because it is the steadier guide to where headline PCE is heading. ### What is core inflation? Core inflation is the same shopping list with food and energy taken out. Those two swing hard for reasons no central bank can control, so removing them gives a steadier read. Core is not your cost of living, because food and fuel are real bills you really pay. It is a signal, not a receipt. ### What is supercore inflation? Supercore is services with energy and housing taken out. Things like haircuts, restaurants and repairs. The idea is that wages are the biggest cost of those services, so this group should show whether pay rises are pushing prices up. A supercore PCE measure is published officially. There is no official supercore CPI, so the one on this page is our own calculation. ### What is trimmed-mean inflation? A trimmed mean crosses off the biggest price rises and the biggest price falls each month, then averages what is left. Core always removes the same two categories. A trimmed mean removes whichever ones went wild that month, so it changes from month to month. Trimmed mean and median versions of both CPI and PCE are on this page. ### Why is the housing number always behind the real rental market? Because most renters sign up for a year, and their rent cannot change until that year is up. New rents agreed today take a long time to feed through. Roughly a year, and sometimes longer. So the housing part of inflation is usually telling you about last year. ### Why do these measures disagree with each other? Because they are built from different shopping lists, weighted differently, with different rules about what to ignore. A gap between two of them is useful information. It usually means one category is doing something unusual. Look at what is inside a measure before you decide it is the right one. ### When is the next inflation release? CPI comes out monthly, usually mid-month at 8:30am New York time, covering the previous month. PCE follows near the end of the same month.
