Enter the surplus value ($) and the capital invested ($) into the calculator to determine the Rate of Profit. 

Rate of Profit Formula

The following formula is used to calculate the Rate of Profit. 

ROP = SV / CI
  • Where ROP  is the Rate of Profit
  • SV is the surplus value ($) 
  • CI is the capital invested ($) 

How to Calculate Rate of Profit?

The following example problems outline how to calculate Rate of Profit.

Example Problem #1:

  1. First, determine the surplus value ($). In this example, the surplus value ($) is given as 1000.
  2. Next, determine the capital invested ($). For this problem, the capital invested ($) is given as 3000.
  3. Finally, calculate the Rate of Profit using the equation above: 

ROP = SV / CI

The values given above are inserted into the equation below:

ROP = 1000 / 3000 = .33

Example Problem #2: 

The variables needed for this problem are provided below:

surplus value ($) = 140

capital invested ($) = 200

Entering these values and solving gives:

ROP = 140 / 200 = .7
