CPI by year.
The BLS Consumer Price Index for All Urban Consumers (CPI-U, all items, U.S. city average, 1982-84 = 100) as an annual average for every year since 1913, the change from the year before, and a lookup that converts an amount between any two years.
Short answer: The CPI-U annual average was 321.943 for 2025 and 313.689 for 2024, a rise of 2.6%. The October 2026 index is 337.511 and the January to October 2026 mean is 332.769. The index averaged 9.883 in 1913, so $1 in 1913 had the buying power of about $32.58 in 2025 (321.943 ÷ 9.883).

Each annual average is the mean of the twelve monthly, not seasonally adjusted, all-items indexes that BLS publishes for that year. The year-over-year change is derived by dividing one annual average by the previous one. The largest rises in the table are 17.8% in 1917 and 17.3% in 1918; the largest falls are 10.9% in 1921 and 10.3% in 1932. The 2022 average rose 8.0%, the biggest increase since 1981.
2026 month by month
| Month | CPI-U index |
|---|---|
| January 2026 | 325.252 |
| February 2026 | 326.785 |
| March 2026 | 330.213 |
| April 2026 | 333.020 |
| May 2026 | 335.123 |
| June 2026 | 333.952 |
| July 2026 | 333.918 |
| August 2026 | 334.980 |
| September 2026 | 336.940 |
| October 2026 | 337.511 |
October 2026 is the latest month, published November 10, 2026. BLS did not collect October 2025 data during the lapse in appropriations, so the October 2026 release carries no 12-month percent change for the all-items index. The 2025 annual average of 321.943 that BLS publishes is based on the eleven months it did collect; the mean of those eleven monthly indexes reproduces it exactly. The November 2026 index is scheduled for December 10, 2026.
Worked example
$100 in 2000 becomes $100 × (321.943 ÷ 172.200) = $186.96 in 2025, a cumulative rise of 87.0%. $1,000 in 1990 becomes $1,000 × (332.769 ÷ 130.658) = $2,546.87 measured against the January to October 2026 average, a rise of 154.7%; that second figure will move once the full 2026 average exists.
Method
The monthly indexes were pulled from the BLS public API for series CUUR0000SA0 (CPI-U, all items, U.S. city average, not seasonally adjusted) on November 11, 2026, ten years at a time, and averaged per calendar year. The result matches the annual averages BLS prints for 2024 (313.689) and 2025 (321.943). The converter multiplies your amount by the ratio of the two annual averages.
What this does not cover
- The CPI-W, the index for urban wage earners and clerical workers that Social Security uses for its cost-of-living adjustment. It is a different series.
- The chained CPI (C-CPI-U) that the IRS uses to index tax brackets, and seasonally adjusted figures used for month-to-month news.
- Regional and metropolitan-area indexes, and the separate food, energy and shelter components.

Common mix-ups
-
Often assumedThe CPI annual average for a year is simply its December index.
What the source saysThe BLS annual average is the mean of the twelve monthly indexes: the published 2025 average is 321.943 while the December 2025 index alone is 324.054. [1]
-
Often assumedEvery CPI release reports a 12-month inflation rate for the headline index.
What the source saysThe November 10, 2026 release states that BLS cannot publish 12-month percent changes for October 2026 where October 2025 data are unavailable, because October 2025 prices were not collected. [2]
-
Often assumedA CPI-U reading of 337.511 means prices have risen 337 percent since the base period.
What the source saysWith 1982-84 set to 100, an index of 337.511 means prices are about 3.4 times the base-period level, a rise of roughly 237 percent. [2]
-
Often assumedThe Social Security COLA is computed from the CPI-U figures in this table.
What the source saysThe SSA notice for 2027 says the agency follows precedent by continuing to use the CPI-W, the index for urban wage earners and clerical workers, not the CPI-U. [3]

Frequently asked questions
What is the CPI for 2025?
The CPI-U annual average for 2025 is 321.943 (1982-84 = 100), up 2.6% from 313.689 in 2024. It equals the mean of the eleven monthly indexes BLS published; October 2025 was not collected.
What is the latest CPI index number?
The October 2026 CPI-U all-items index is 337.511, published by BLS on November 10, 2026. The January to October 2026 average is 332.769.
How do I calculate inflation between two years with this table?
Divide the later year’s annual average by the earlier year’s and multiply your amount by the result. $100 in 2000 × (321.943 ÷ 172.200) is $186.96 in 2025.
Why is there no 12-month inflation rate for October 2026?
BLS did not collect October 2025 prices during the lapse in appropriations, so its November 10, 2026 release says it cannot publish 12-month changes for October 2026 where October 2025 data are unavailable.
Is the annual average the same as the December index?
No. The annual average is the mean of the twelve monthly indexes. For 2025 the average is 321.943 while December 2025 alone was 324.054.
Is this the index used for the Social Security COLA?
No. The COLA is based on the CPI-W. The CPI-U in this table is the headline index for all urban consumers, which covers a broader population.
Does the IRS use this index for tax brackets?
No. Tax brackets and the standard deduction are indexed with the chained CPI (C-CPI-U), which usually rises a little more slowly than the CPI-U shown here.
What does 1982-84 = 100 mean?
The index is scaled so that the average price level of 1982 to 1984 equals 100. An index of 337.511 means prices are about 3.4 times that level, a rise of roughly 237%.
