## Return on Objective Formula

The following formula is used to calculate the Return on Objective.

**ROO = (OA – OB) / OB * 100**

- Where ROO is the Return on Objective (%)
- OA is the objective after activity
- OB is the objective before activity

## How to Calculate Return on Objective?

The following example problems outline how to calculate Return on Objective.

Example Problem #1:

- First, determine the objective after activity.
- The objective after activity is given as: 40.

- Next, determine the objective before activity.
- The objective before activity is provided as: 20.

- Finally, calculate the Return on Objective using the equation above:

ROO = (OA – OB) / OB * 100

The values given above are inserted into the equation below and the solution is calculated:

ROO = (40 – 20) / 20 * 100 = 100.00 (%)

Example Problem #2:** **

For this problem, the variables needed are provided below:

objective after activity = 50

objective before activity = 30

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
