Inflation Calculator
See how inflation changes the value of money over time — what something will cost in the future, and how much today's money will actually be worth (its purchasing power) down the line. Updates as you type.
FAQ
How does inflation affect my money?
Inflation raises prices over time, so the same money buys less later. At 3% a year, something costing $100 today costs about $134 in ten years — and $100 held as cash would only buy about $74 of today's goods by then.
How is future cost calculated?
Future cost = amount × (1 + rate)^years. Purchasing power is amount ÷ (1 + rate)^years — what a future sum is worth in today's money. This tool shows both.
What inflation rate should I use?
Many economies target ~2-3% long-term, but actual rates vary and can spike. Try a few to see a range.
Why does inflation matter for saving and investing?
Idle cash loses real value to inflation. To preserve purchasing power, your savings need a return that keeps pace with it — the main argument for investing rather than holding only cash.
