- Formula
- Future cost = current cost × (1 + annual inflation/100)^years. Purchasing power = amount / (1 + annual inflation/100)^years.
- Variables
- I want to know: Future cost, Past value
- Amount
- Average yearly inflation
- Years
- Units
- Average yearly inflation: %
- Years: years
- Use the same selected currency for all monetary inputs. Changing the symbol does not convert exchange rates.
- Example
- At 3.5% a year, something costing 1,000 today will cost about 1,411 in 10 years.
- Assumptions
- The result follows the selected options and supplied inputs. Displayed values may be rounded; check input precision before using the result.

Interpretation and limitations
- What inflation rate should I use? A long-run average for your country; about 2–3% in many developed economies and higher in many emerging ones.
- What is the rule of 70? Divide 70 by the inflation rate to estimate how many years prices take to double.
