Reference table

Exponential Decay Table: Final value by Initial value

Reference table of final value for Exponential Decay across a range of initial value values — exact, engine-computed figures you can read off at a glance.

By Vikram Iyer, M.Sc Mathematics · Updated Jun 2026 · 1 min read

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.

Frequently asked questions

Each cell is computed with the standard formula using exact arithmetic — the same calculation behind our Exponential Decay Calculator — so every figure is accurate for the stated assumptions.

Yes. The table covers common initial value values; for any exact figure, enter your own numbers in the Exponential Decay Calculator.
