How this tool works

Future cost = amount × (1 + inflation)^years. Future purchasing power = amount ÷ (1 + inflation)^years. These answer different questions and are shown separately.

Try an example

For example, enter the cost of an item today to estimate its future cost at your assumed inflation rate. The purchasing-power figure instead shows what the same nominal amount in the future might buy in today’s money.
