Inflation Calculator

About this calculator

Inflation quietly erodes purchasing power every year, so an expense that costs a fixed amount today will cost noticeably more by the time you actually need to pay it, whether that's a child's education fee a decade away or your own living expenses in retirement. The gap compounds year over year, which means linear guesses ('add a bit each year') consistently understate the real future cost, especially over 10-20 year horizons. This calculator applies Future cost = Present cost × (1 + inflation rate)^years to your present-day amount, expected annual inflation rate and time period, and returns the exact inflated figure. Use it to size long-term financial goals realistically, so the amount you're saving toward actually matches what you'll need to spend, rather than what the expense costs in today's money.
