How Inflation Is Calculated — And Why Many Americans Think It’s Wrong

The government says inflation is 2.4%. Your grocery bill says otherwise. This gap between the official numbers and what people actually feel at the checkout line has become one of the most politically charged disputes in American economics — and in 2026, there are more reasons than ever to question whether the official figures are telling the full story. Here’s how inflation is actually measured, what’s broken about it right now, and why even professional economists have started to lose confidence in the data.

What the CPI Actually Measures — And What It Misses

Inflation in the U.S. is measured by the Consumer Price Index, published monthly by the Bureau of Labor Statistics. The BLS tracks the prices of a “market basket” — a fixed set of goods and services that a typical urban American household buys, including food, rent, gas, medical care, and clothing. When that basket gets more expensive month over month, that’s inflation.

The January 2026 headline CPI came in at 2.4% year-over-year, down from 2.7% in December. On paper, that looks like progress. In practice, it’s more complicated.

The BLS acknowledged openly that CPI data collection has been reduced due to a staffing shortage caused by Trump’s federal hiring freeze, cutting back the in-person price checks that normally account for 60% of CPI data. Former Commerce Department statistics chief Jed Kolko called it “collateral damage” and warned: “This isn’t the moment when we want our read on inflation to get fuzzier.”

The Government Shutdown Made the Numbers Even Messier

Here’s something most Americans don’t know: the October 2025 CPI was never collected. The 43-day government shutdown that ran from October 1 to November 12 shut down the BLS entirely, leaving a blank where a month of price data should be.

According to CNBC’s breakdown of the January 2026 CPI, when the BLS had to calculate November without October’s data, it was forced to assume prices hadn’t changed for large categories — particularly rent. That created an artificial dip in the numbers. Moody’s chief economist Mark Zandi estimated that if the missing October data were included, the actual CPI inflation rate would be closer to 2.7%, not 2.4%. The distortion won’t fully correct itself for several more months.

So when politicians point to “falling inflation,” they’re partly reading a statistical ghost.

Why Your Personal Inflation Rate Is Probably Higher Than 2.4%

Even in a normal data environment, the CPI measures the average American — not you. As the Peterson Institute for International Economics explains, consumers perceive inflation based on how often they buy something, not how much of their budget it takes up. Eggs make up less than 0.2% of the CPI basket — but when egg prices jumped due to the avian flu outbreak, millions of Americans felt it every week. Beef is up 15% and coffee is up 18% annually, according to current CPI data, yet these spikes are diluted in the overall index by categories that are barely moving.

Housing is the most glaring distortion. Rent and something called Owner’s Equivalent Rent — the BLS’s estimate of what homeowners would theoretically pay to rent their own homes — together make up over 35% of the entire CPI, according to J.P. Morgan Asset Management. That measure is slow-moving by design. It consistently lags real-world rents by 12 to 18 months, meaning the CPI can show housing inflation cooling while actual renters face price hikes their landlord imposed last spring.

What’s Coming Next — And Why It Could Get Worse

The official numbers may be flattering right now, but economists don’t expect them to stay that way. The Peterson Institute warns that inflation could exceed 4% by the end of 2026, driven by the lagged effects of tariffs, tightening labor supply from reduced immigration, and a fiscal deficit that could exceed 7% of GDP. Companies that absorbed tariff costs through 2025 are now passing them on in small, staggered price increases that don’t cause a single dramatic spike — but add up over time.

As CNN reported, economist Gregory Daco of EY-Parthenon warned that businesses typically revisit pricing at the start of a new year, making the first quarter of 2026 a likely flashpoint for goods inflation. The Federal Reserve, watching all of this, has signaled it won’t cut interest rates until at least June.

The bottom line: the government’s 2.4% headline figure is real, but it’s also incomplete, distorted by missing data, and weighted toward categories that don’t reflect how most Americans actually spend their money. If it feels like prices are still rising faster than the official number suggests — you’re probably not wrong.
