Inflation Calculator
See what today's money will be worth — and what things will cost — after years of inflation.
Inflation is compound interest working against you. At 6% inflation, prices double roughly every 12 years — which means a retirement plan, a college fund, or even a long-term rental agreement that ignores inflation is quietly planning with the wrong numbers.
This calculator shows both sides of the same coin: what an expense costing a given amount today will cost after N years of inflation, and what today's money will actually be worth (its purchasing power) at that time. Enter an amount, an assumed annual inflation rate, and a number of years to see the compounding effect instantly.
