This US inflation calculator shows what an amount of money from any year since 1913 is worth in another year, using the official Consumer Price Index (CPI-U) from the Bureau of Labor Statistics. Find out what your grandparents' salary, an old house price or a 1990s movie ticket would cost today, how much buying power the dollar has lost and the average inflation rate between any two years.

How the Inflation Calculator Works

The Consumer Price Index measures the average price of a fixed basket of goods and services bought by urban households – food, housing, gasoline, medical care, clothing and more. Because the basket stays the same, the ratio of two years' index values shows how much prices changed:

Value in year B = amount in year A × (CPI in year B ÷ CPI in year A)

Example: the average CPI was 172.2 in 2000 and 321.9 in 2025. So $100 in 2000 has the same buying power as 100 × 321.9 ÷ 172.2 = $186.93 in 2025 – prices rose 86.9%, an average of about 2.5% a year.

The average yearly rate is a compound rate: (CPIend ÷ CPIstart)1/years − 1. The calculator uses annual averages, so results are for the year as a whole rather than a specific month.

What $100 From the Past Is Worth Today

Using the 2025 annual average CPI:

Year$100 then equals in 2025
1913$3,251.52
1930$1,927.54
1950$1,335.68
1960$1,087.50
1970$829.64
1980$390.66
1990$246.29
2000$186.93
2010$147.59
2020$124.38

Notice that $100 from 1940 is worth more today than $100 from 1930. Prices fell during the Great Depression, so a 1940 dollar bought more than a 1930 dollar. For those years the calculator shows deflation – the dollar gained buying power.

US Inflation in Recent Years

Annual average inflation was 1.2% in 2020, then jumped to 4.7% in 2021 and 8.0% in 2022 – the highest in four decades – before easing to 4.1% in 2023, 3.0% in 2024 and 2.6% in 2025. The record in modern times was 13.5% in 1980. The Federal Reserve aims for inflation of 2% a year over the long run.

Why Inflation Matters for Your Money

  • Savings: money in an account paying less than inflation loses buying power every year. At 3% inflation, prices double in about 23 years.
  • Salary: a raise smaller than inflation is a pay cut in real terms. Compare your raise with the yearly figure in the table below the calculator.
  • Retirement: $50,000 a year of spending today will need roughly $90,000 in 20 years at 3% inflation.
  • Comparisons: to compare prices, wages or home values across decades fairly, convert them to the same year's dollars first.

Limits of the CPI

CPI-U is an average for urban consumers. Your own inflation depends on what you buy and where you live – housing and health care costs have risen faster than the overall index, and electronics have become cheaper. The 2026 figure is based on the months published so far and is updated when the BLS releases the full-year average. For month-by-month comparisons, use the BLS CPI Inflation Calculator.

Frequently Asked Questions

How much is $100 from 2000 worth today?
$100 in 2000 had the same buying power as about $187 in 2025 and about $194 in 2026, based on the Consumer Price Index.
How do you calculate inflation between two years?
Divide the CPI of the later year by the CPI of the earlier year and multiply by the amount. For the percentage change, subtract 1 and multiply by 100. The calculator does both and also shows the average yearly rate.
What was the highest inflation rate in US history?
Since 1913, annual average inflation peaked at about 17% in 1917 and 1918 and 14% in 1947. In modern times the peak was 13.5% in 1980. In 2022 it reached 8.0%, the highest in 40 years.
What is CPI-U?
CPI-U is the Consumer Price Index for All Urban Consumers, published monthly by the Bureau of Labor Statistics. It covers about 93% of the US population and is the most widely used measure of inflation.
Why is $100 from 1940 worth more today than $100 from 1930?
Prices fell during the Great Depression (deflation): the CPI was 16.7 in 1930 and 14.0 in 1940. A dollar therefore bought more in 1940, so it converts to more of today's dollars.
What is the average inflation rate in the US?
From 2000 to 2025, US inflation averaged about 2.5% a year. Over the full period since 1913 it has averaged about 3.2% a year.
