Controllable margin $
Return on investment for 2020 %

Controllable margin =$125,000

Return on investment = 20%

Explanation:

Controllable margin is the difference between the sales revenue and the controllable cost. Controllable costs include variable and fixed cost directly under the control of the manager and which are influenced by his decisions.

Controllable margin - Sales revenue - variable cost - controllable fixed cost

Controllable margin= $500,000 - $300,000 - 75,000 = $125,000

Controllable margin =$125,000

Return on investment = (controllable margin/ Average investment) × 100

                     = (125,000/625,000) ×  100 = 20%

Return on investment = 20%
