How Inflation Is Measured
The Consumer Price Index tracks the price of a fixed basket of goods and services, from rent and groceries to gasoline and doctor visits. When the index rises from 100 to 110, the same basket costs 10% more, so a dollar buys 10% less.
Value then → now = Amount × CPI(now) ÷ CPI(then)
Total inflation = (CPI(now) ÷ CPI(then) − 1) × 100
Average per year = ((CPI(now) ÷ CPI(then))1/years − 1) × 100

Frequently Asked Questions
How does the inflation calculator work?
It multiplies your amount by the ratio of the Consumer Price Index on the two dates: value = amount × CPI(end) ÷ CPI(start). $100 in 2000 buys about as much as $186.96 did in 2025, because average prices rose 87% over those 25 years, about 2.5% a year.
Where does the data come from?
From the Consumer Price Index for All Urban Consumers (CPI-U), U.S. city average, all items, published monthly by the US Bureau of Labor Statistics since 1913. It is the index used in most news reports about inflation. The data runs from January 1913 to December 2025.
Why is there no figure for October 2025?
The BLS did not collect October 2025 prices because of the federal government shutdown, so there is no index for that month. The 2025 annual figure used here is the average of the 11 months that were published.
What is a normal rate of inflation?
The Federal Reserve and the European Central Bank both aim for about 2% a year. US inflation averaged about 3% a year from 1913 to 2025, with peaks of 17% in 1918, 14% in 1947 and 13.5% in 1980, and 8% in 2022; prices fell in the early 1930s.
Why might my own cost of living have changed differently?
CPI-U measures the average basket of goods and services bought by urban households. If you spend more than average on rent, health care or college, which have risen faster, or on electronics, which have become cheaper, your personal inflation rate will differ.
Can I use it for other currencies?
No, it uses US prices only. Other countries publish their own indexes, such as the UK's CPI from the Office for National Statistics and the euro area's HICP from Eurostat, and their inflation history is different.
