The calculator needs JavaScript. The tables below give the same numbers for common cases.
How it is worked out
- Future price = amount × (1 + inflation)^years = $1,000.00 × 1.343916 = $1,343.92.
- You enter the inflation rate; this page does not look up official CPI figures.
| Inputs | Answer |
|---|---|
| Amount today: 1000; Average yearly inflation: 3; Years: 10 | At 3% inflation a year, what costs $1,000.00 today costs about $1,343.92 in 10 years; $1,000.00 then buys what $744.09 buys today. |
| Amount today: 250000; Average yearly inflation: 2.5; Years: 30 | At 2.5% inflation a year, what costs $250,000.00 today costs about $524,391.89 in 30 years; $250,000.00 then buys what $119,185.67 buys today. |
| Amount today: 50; Average yearly inflation: 4; Years: 5 | At 4% inflation a year, what costs $50.00 today costs about $60.83 in 5 years; $50.00 then buys what $41.10 buys today. |
How to use it
At a steady inflation rate, prices grow by (1 + rate)^years. Something that costs $1,000 today costs about $1,344 in 10 years at 3%, and $1,000 then buys only what $744 buys now.
This calculator uses the rate you enter; it does not look up official price-index (CPI) data for a particular country and period. These are estimates from the numbers you type, not financial advice or an offer; real products add fees and change rates.
