How to Calculate and Solve for Future Worth | Equal Payment Series | Economic Equivalence

Last Updated on April 6, 2024

The image above represents future worth. To calculate future worth, three essential parameters are needed and these parameters are Annual Amount or Worth (A), Interest Rate (i) and Number of Years (N).

The formula for calculating future worth:

F = A[((1 + i)^N) – 1] / i

Where;

F = Future Worth or Amount
A = Annual Worth or Amount
i = Interest Rate
N = Number of Years

Let’s solve an example;
Find the future worth when the annual worth is 21, the interest rate is 0.2 and the number of years is 9.

This implies that;

A = Annual Worth or Amount = 21
i = Interest Rate = 0.2
N = Number of Years = 9

F = A[((1 + i)^N) – 1] / i
F = 21[((1 + 0.2)⁹) – 1] / 0.2
That is, F = 21[((1.2)⁹) – 1] / 0.2
F = 21[5.159 – 1] / 0.2
F = 21[4.159] / 0.2
So, F = 21 x 20.79
F = 436.77

Therefore, the future worth is ₦436.77.
