Inflation Calculator
See how inflation erodes your purchasing power over time.
Overview
Inflation compounds, so the purchasing power of a fixed sum decays geometrically rather than linearly. At three percent annually, money retains about 74 percent of its value after ten years and 55 percent after twenty. The reciprocal calculation gives the nominal sum required in a future year to command the goods a given amount buys today.

About
The real return on an investment is the nominal return adjusted for the same compounding. Subtracting the inflation rate from the nominal rate approximates the answer and is accurate enough at low rates; the exact Fisher relation divides the two growth factors instead, and the difference between the two methods widens as rates rise.
Measured inflation is an index over a representative basket, so an individual's experienced rate differs according to what they buy. Housing, education and medical costs have risen faster than headline indices across most developed economies, while consumer electronics have fallen.
