Inflation Calculator: What Is Your Money Worth Today?
Our free inflation calculator shows how the buying power of the US dollar has changed since 1913. Pick a start year and an end year, enter an amount, and see what that money would be worth in the other year, along with the total inflation and the average yearly rate. A year-by-year table lists every price index and annual change in between. A second tab projects future prices from an inflation rate you choose.
Quick answer: $100 in 2000 has the buying power of about $186.96 in 2025. Prices rose 87.0% in total, an average of 2.53% a year. Or put another way, $100 today buys what about $53.49 bought in 2000.
What Is Inflation?
Inflation is the general rise in prices over time. When prices rise, each dollar buys less than it did before, so the same amount of money has less purchasing power. Economists usually measure inflation with a price index that tracks the cost of a typical basket of goods and services, such as food, housing, transport and healthcare. The most widely used index in the United States is the Consumer Price Index.
How the Calculation Works
The calculator compares the Consumer Price Index in the two years you choose. The index is a number, with the average of 1982 to 1984 set at 100. Dividing the end-year index by the start-year index tells you how much prices changed, and multiplying your amount by that ratio gives the equivalent value.
The table shows what $100 from several years is worth in 2025 dollars.
| Year | $100 is worth in 2025 | Total inflation | Average yearly rate |
|---|---|---|---|
| 1980 | $390.71 | 290.7% | 3.07% |
| 1990 | $246.32 | 146.3% | 2.61% |
| 2000 | $186.96 | 87.0% | 2.53% |
| 2010 | $147.64 | 47.6% | 2.63% |
| 2020 | $124.39 | 24.4% | 4.46% |
Where the Data Comes From
The figures are annual averages of the Consumer Price Index for All Urban Consumers (CPI-U), published by the US Bureau of Labor Statistics. The data runs from 1913, when the index began, to 2025. You can also choose the latest month as the end point, which uses the most recent monthly index, so you can see what past money is worth in today's prices. Because early index values are published to one decimal place, results for the oldest years may differ slightly from tools that use unrounded numbers.
A Century of Prices
Over the whole period, prices rose about 32.5 times between 1913 and 2025, an average of about 3.16% a year. The path was uneven. Prices fell by more than 10% in both 1921 and 1932, inflation reached 13.5% in 1980, and it climbed to about 8% in 2022. Small differences in the yearly rate add up over decades, which is why long-term savings and incomes are so sensitive to inflation.
Planning for Future Prices
On the Future Prices tab you enter a yearly inflation rate and a number of years. At 3% a year, something that costs $100,000 today would cost about $180,611 in 20 years, while $100,000 held in cash would only buy what $55,368 buys now. This is why savings need to earn more than inflation to keep their value. To see how growth can outpace rising prices, try the compound interest calculator, the savings calculator or the investment calculator. For retirement planning, the retirement calculator and the 401k calculator both include an inflation adjustment, and the salary calculator can help you judge whether a raise keeps up.
Who Uses an Inflation Calculator?
People comparing old and new prices, writers and students researching history, savers and retirees planning for rising costs, employees checking whether a pay rise beats inflation, and businesses reviewing contracts and rents. Results are estimates based on the average consumer basket, and your own costs may rise faster or slower.
