  5. Read the answer and any additional results below the form. Check the units and the limits of the method.

Formula and method

Future equivalent cost = current amount × (1+annual inflation/100)^years
Future purchasing power = current amount/(1+annual inflation/100)^years

The formula uses the units and definitions shown above. Each input is substituted before the arithmetic is evaluated; the calculated output is rounded for display.

Worked example

Current amount: 10000, Annual inflation (%): 5, Years: 10. The result is 16,288.94626777 (future equivalent cost).
