Inflation Calculator: What Is Your Money Worth Today?
Compare purchasing power between two years using U.S. annual-average CPI-U data.
Calculate your scenario
How the calculation works
The calculator uses annual-average, not monthly, U.S. city average all-items CPI-U. It divides the destination-year index by the starting-year index and multiplies by the amount. For a reverse comparison, enter the later year first. Data are frozen locally for 2000–2024; 2025 and incomplete 2026 are unsupported. CPI represents an average basket and may differ from your own spending.
Worked example
For example, $100 in 2000 becomes approximately $182.17 in 2024 because 313.689 ÷ 172.2 × $100 = $182.17. The price level rose about 82.17%; the purchasing power of a fixed dollar fell about 45.11% over that span.
How to read your results
The primary figure summarizes the entered scenario. The other figures separate deposits or contributions from modeled interest or investment growth, or show the change in purchasing power or payoff cost. Change an input to compare another scenario; the previous result is hidden until you calculate again.
Frequently asked question
Why can the percentage purchasing-power loss differ from the price increase?
The two percentages use reciprocal bases: price change compares the later index with the earlier one, while purchasing power compares the earlier index with the later one.
