Inflation Calculator
Find how much a sum is worth in the past or future after inflation.
How to use this tool
- Enter the amount and currency.
- Choose direction: past or future.
- Set the inflation rate and years.
- View the adjusted value and annual table.
How it works
Compound growth applied to the amount: (1 + rate)^years for the future; the inverse for the past.
Tips
- Use long-run averages, not last year, for planning.
- Salary growth above inflation is real raise — compare yours.
- History shows small rate differences compound into big gaps.
Limitations
A single rate is applied throughout; real-world inflation varies year to year.
Frequently asked questions
What inflation rate should I use?
Long-run averages run 2–3.5% in many economies; the calculator's default is 3% and can be edited per your market.
What's the formula?
Future value = present value × (1 + rate)^years. Past value divides instead.
Does it work in any currency?
Yes — it's rate-in and currency-agnostic; pick your currency for formatting.
