The same things will cost
How it works
future cost = amount × (1 + rate)^yearsbuying power = amount ÷ (1 + rate)^yearsWorked example
- 1.03^10 = 1.3439
- 1,000 × 1.3439 = 1,343.92
- 1,000 ÷ 1.3439 = 744.09 of today’s money
Frequently asked questions
Which inflation rate should I use?
Central banks in the US, the euro area and the UK target about 2% a year; long-run averages have been around 3%. Use your country’s recent rate for the next few years and a long-run rate for decades.
What is buying power?
What an amount can buy compared with today. At 3% inflation, 1,000 in 10 years buys what about 744 buys today.
Does this use official price data?
No, it applies a constant yearly rate that you choose. Real inflation changes every year.
