Calculate the effect of inflation
See what an amount today will be worth in the future, or what a past amount is worth today, at a given inflation rate.
Today's amount and an average annual inflation rate.
Project it forward to a future cost, or backward to a past equivalent value.
The inflation-adjusted amount, in plain language.
Frequently asked
How is this calculated?
Future cost: amount × (1 + rate)^years. Past value: amount ÷ (1 + rate)^years. The same compounding relationship, applied in each direction.
What inflation rate should I use?
There's no single right answer. A long-run average for general consumer prices is a reasonable starting point, but actual inflation varies by year and by what you're buying.
Where do I find a realistic inflation rate to use?
A national statistics agency or central bank typically publishes historical and target inflation rates. Use a figure relevant to your country and time period rather than a guess.
Can I use this to adjust a salary or price for inflation?
Yes. Enter the amount, the rate, and the number of years, either projecting forward or discounting backward.
Does inflation apply uniformly to everything?
No, this uses one average rate you supply. Real-world price changes vary a lot by category (housing, food, fuel), so treat the result as a general estimate.
What's the difference between real and nominal value here?
The "past equivalent value" direction is essentially showing real value, what a future amount is worth in today's purchasing power.
