Inflation calculator
Estimate what today’s amount would need to grow to in order to buy the same things later, and how much today’s amount would buy at an assumed inflation rate.
How it works
Amount needed = Amount × (1 + inflation ÷ 100)^years. Buying power = Amount ÷ (1 + inflation ÷ 100)^years.
Assumptions
- One constant inflation rate for every year. Official figures are published by the government (consumer price index); this tool does not fetch them.
- The rate is your assumption; it is not a forecast.
