Online Inflation Calculator

See how inflation changes the value of money over time — what a sum will cost in the future, or what a past amount is worth today.

Inflation Formula

Future value (what it will cost): FV = PV × (1 + r ÷ 100)^t
Past value (today's worth): PV = Amount ÷ (1 + r ÷ 100)^t
where r = inflation rate and t = number of years.
