Use this free Inflation Calculator to estimate how inflation may affect future cost, present value, and purchasing power over time. This page includes two practical modes: future value with inflation and present value / purchasing power.
Inflation matters because the same amount of money does not always buy the same amount of goods and services over time. Even moderate inflation can meaningfully reduce purchasing power over longer periods.
This calculator is especially useful for savings goals, retirement planning, salary comparisons, education costs, and long-term budgeting. It also pairs well with the Savings Calculator, Compound Interest Calculator, and Retirement Calculator.
Results are based on a fixed annual inflation rate entered by the user and are intended for planning estimates only.
Inflation is the general rise in prices over time. When prices increase, the same amount of money usually buys less than it did before. In other words, inflation reduces purchasing power.
For short periods, inflation may seem small. But over many years, even a moderate inflation rate can make a meaningful difference in what a given amount of money can actually buy.
This page includes two practical calculation modes:
Choose the mode that matches your question, enter the amount, inflation rate, and time period, and the calculator will update automatically.
If something costs $100 today and inflation averages 3% per year, the future price after 10 years will be meaningfully higher than $100.
A cost of $1,000 today at 5% inflation over 20 years can rise significantly, showing why long-term financial planning should account for inflation.
If your salary rises over time but prices also rise, inflation-adjusted purchasing power may increase less than the nominal salary suggests.
A retirement or education savings goal should often be adjusted for inflation, because the future cost may be much higher than the current cost.
In future value mode, the result estimates how much a current amount may grow in price over time if inflation stays at the chosen rate.
In present value mode, the result estimates what a future amount is worth in today’s purchasing power. This can be useful when comparing money across years in more realistic terms.
This Inflation Calculator uses a fixed annual inflation rate entered by the user. Real-world inflation does not move in a perfectly fixed straight line, and actual inflation may be higher or lower in future years.
This page does not replace official CPI history or future inflation forecasting. It is most useful as a practical planning tool for estimates and scenario testing.

Inflation is the general increase in prices over time, which tends to reduce purchasing power.
When inflation rises, the same amount of money usually buys fewer goods and services than before.
That depends on your planning assumptions. Many people use a simple expected annual rate for rough scenario testing, but real inflation can change over time.
No. It does not forecast inflation. It only estimates outcomes using the fixed inflation rate you enter.
No. This is a planning calculator, not an official CPI historical database or government inflation report.
Yes. It can be useful for estimating how future living costs may differ from current costs when planning long-term savings.
Because the amount you need in the future may be higher than the amount that feels sufficient today.
Yes. The page is designed to work on phones, tablets, and desktop devices.
