Enter the current security value (\$) and the previous security value (\$) into the Return on Security Calculator. The calculator will evaluate and display the Return on Security.

## Return on Security Formula

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

ROS = (CSV-PSV) / PSV * 100

• Where ROS is the Return on Security (%)
• CSV is the current security value (\$)
• PSV is the previous security value (\$)

## How to Calculate Return on Security?

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

Example Problem #1:

1. First, determine the current security value (\$).
• The current security value (\$) is given as: 500.
2. Next, determine the previous security value (\$).
• The previous security value (\$) is provided as: 300.
3. Finally, calculate the Return on Security using the equation above:

ROS = (CSV-PSV) / PSV * 100

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

ROS = (500-300) / 300 * 100 = 66.67 (%)

Example Problem #2:

For this problem, the variables needed are provided below:

current security value (\$) = 600

previous security value (\$) = 400

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

ROS = (CSV-PSV) / PSV * 100 = ?
