Reverse Interest Definition

A reverse interest is a process of calculating a principal amount on an investment or loan given the accumulated amount, interest rate per period, and a number of periods.

Example Calculation

Let's assume the following values:

Step 1: Calculate \( (1 + r)^n \):

\[ (1 + 0.05)^{10} = 1.62889 \]

Step 2: Divide the accumulated amount by the result from step 1:

\[ P = \frac{1000}{1.62889} = 613.91 \]
