Inflation assumed at 6 percent a year, not an official forecast.

How it works

Inflation compounds like interest, but against you: each year's price rise applies to the already higher price. The calculator also works backwards to show what a future amount buys in today's terms.

Formula

Future cost = amount x (1 + inflation)^years; today's value = amount / (1 + inflation)^years

  • The rate is your input. We do not show an official inflation series here because we have not yet verified one end to end.

Frequently asked questions

How do I calculate the future cost of something?

Multiply today's cost by (1 + inflation rate) raised to the number of years.

What inflation rate should I use?

Any rate is an assumption; try a range to see the effect.

What is purchasing power?

What a sum of money can buy. When prices rise, the same rupees buy less.
