How to calculate rate of return

The formula for calculating the rate of return is as follows:

Rate of return=(Final value − Initial value)/Initial value×100

Here’s how to calculate it step-by-step:

  1. Subtract the initial value from the final value. This will give you the total change in value over the investment period.
  2. Divide the result from step 1 by the initial value. This will give you the relative change as a decimal.
  3. Multiply the result from step 2 by 100 to convert it into a percentage.
