The inflation calculator below, from The Finance Reveal, shows what a purchase costing a given amount today will cost after years of inflation, which is the same as showing how much buying power idle money quietly loses. Enter an amount, an annual inflation rate, and a number of years.

Why this number matters everywhere

Inflation is the silent variable inside every long-term plan: the retirement target that must be set in future prices, the reason cash savings need competitive interest, and the honest deflator behind every projected investment return. A quick run here puts a number on what “money loses value over time” actually means for your amounts and horizon.

Using it with the other tools

Pair it with the compound interest calculator to see whether a savings rate actually outruns inflation, and with the retirement calculator to sanity-check a projection in today’s terms. The comparison explains why long-term money belongs in investments rather than cash, the case our investing pillar makes, and why even savings accounts should be the competitive kind from our high-yield guide.

Frequently asked questions

What inflation rate should I use?

Many central banks target around two to three percent, while lived experience often runs higher, especially in some countries and categories. Testing a range, low and high, brackets the honest answer better than any single number.

Is inflation the same for everyone?

No. Your personal inflation depends on what you buy: housing, education, and healthcare have often outpaced headline rates. Budgets weighted toward those categories should plan with higher figures.

How do I protect savings from inflation?

Competitive interest for short-term money, diversified investments for long-term money, and skepticism toward any large sum idling at zero percent. Our Saving Money and Investing sections cover both halves.
