About this tool
Inflation quietly shrinks what your money can buy, and over years the effect is larger than most people expect. This calculator projects a steady inflation rate forward to show both the future cost of an amount and how much its purchasing power will have fallen.
Use it to sanity-check long-term plans, savings goals or salary expectations against rising prices. Because it uses a rate you choose, it’s perfect for comparing scenarios. Everything runs in your browser.
Frequently asked questions
How is this calculated?
It compounds the inflation rate over the years, so the future cost is the amount times (1 + rate) to the power of the years.
Is it based on real inflation data?
No. It uses a steady rate you choose, which is ideal for projections and what-if scenarios rather than historical lookups.
