Sources & methodology

Last reviewed January 15, 2026.

Method: Adjusts amounts using compound price growth: future price = present × (1 + i)ᵗ. Historical comparisons follow the CPI-U approach used by the US Bureau of Labor Statistics.

How it works

Costs rise by compounding: future cost = amount × (1 + rate)years. Buying power moves the opposite way: amount ÷ (1 + rate)years shows what a fixed sum would be worth in today equivalent goods after that many years.

Frequently Asked Questions

What inflation rate should I use?
Many developed economies target around 2 to 3 percent per year, but it varies. Use a figure that matches your country and time period.
What is the difference between future cost and buying power?
Future cost is what the same basket of goods will cost later. Buying power is how much a fixed amount of money will actually buy after inflation.
Does this use historical inflation data?
No, it projects forward using the single rate you enter, so you can model any scenario.
