This exponential decay reference table shows the final value for a range of initial value values, assuming a decay rate per period of 5% and a number of periods of 10. Every figure is computed with the same engine that powers our Exponential Decay Calculator, so the numbers are exact.

How to use this table
Find the row closest to your initial value and read across to the final value. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Exponential Decay Calculator for a precise answer.
Need a value that is not in the table? — the Exponential Decay Calculator does it instantly, for free, with the formula and a worked example built in.
