US Inflation Rate (CPI)

The latest US Consumer Price Index, the monthly trend, and what it means for whether your raise actually grows your purchasing power.

Inflation Rate Over the Last 18 Months

The solid line is headline CPI (all items); the dashed line is core CPI (less food and energy). When headline runs above core, a temporary food or energy shock is usually the cause.

Which Number Our Raise Calculators Use

The headline rate above (4.2%) is the most recent official monthly print. A single month can spike on a temporary energy or food move — which is why core inflation (2.9%) often tells a calmer story.

Because a pay raise lasts all year, our calculators frame “real” raises against a stabler trailing figure — 3.3% (12 months ending March 2026) — rather than chasing each monthly headline. Stable annual figure used site-wide; May 2026 headline spiked to 4.2% on a transient energy shock (core was 2.9%). See our methodology for how every figure on the site is sourced and kept consistent.

What This Means for Your Raise

A raise only grows your purchasing power if it beats inflation. At the latest headline rate of 4.2%, here is what common raises are worth in real terms:

A 3% raise

1.2% real

loses purchasing power against inflation

A 5% raise

+0.8% real

grows your purchasing power after inflation

And because the new dollars of a raise are taxed at your marginal rate, the raise needed to truly break even is a bit higher than inflation. Work out yours with the raise-to-beat-inflation calculator or model a cost-of-living raise.

FAQ

Inflation Rate Questions

What is the current US inflation rate?
The Consumer Price Index (CPI-U, all items, not seasonally adjusted) rose 4.2% over the 12 months ending May 2026, according to the Bureau of Labor Statistics. Core inflation — which strips out volatile food and energy — was 2.9% over the same period.
What is the difference between headline and core inflation?
Headline inflation (all items) includes food and energy, which can swing sharply month to month. Core inflation excludes them, so it tracks the underlying trend more smoothly. When the two diverge, the gap is usually a temporary food or energy shock rather than a change in the broad price trend.
What inflation rate should I use to evaluate my raise?
For a raise, the stabler trailing figure matters more than a single volatile month. Our calculators use 3.3% (12 months ending March 2026) for real-raise framing so the whole site stays internally consistent; the latest monthly print is shown here for reference. Either way, a raise only grows your purchasing power if it beats inflation after tax.
How is the inflation rate calculated?
The 12-month inflation rate is the percentage change in the CPI index between the latest month and the same month one year earlier. We pull the official BLS CPI-U series and compute this year-over-year change for both the all-items and the less-food-and-energy index.
