What This Means

At 3% annual inflation, prices would rise by about 80.61% over 20 years. Meanwhile, $100,000 left unchanged would lose about 44.63% of its purchasing power. In other words, preserving a fortune requires more than simply keeping it safely tucked away.

How this tool works

Enter the amount of money you want to evaluate, choose an annual inflation rate, and select the number of years. The calculator estimates how much money you would need in the future to preserve today's purchasing power, as well as how much purchasing power your current amount would retain if it did not grow.

It also shows the cumulative inflation rate and the estimated percentage of purchasing power lost over the selected period.

The calculation assumes the same inflation rate every year. Actual inflation changes over time, so the results are estimates rather than predictions.
