Inflation Calculator
See how prices and purchasing power change with inflation.
What your money will be worth
Inflation quietly erodes money over time: prices rise, and the same amount buys less. This calculator shows both sides — the future cost of today’s purchase and the shrinking purchasing power of a sum.
At 3% inflation, something costing 1,000 today will cost about 1,344 in ten years, while 1,000 held as cash will buy only what 744 buys now. It is a stark reminder of why idle money loses value.
