Enter the asset value ($) and the exposure factor into the Calculator. The calculator will evaluate the Single Loss Expectancy. 

Single Loss Expectancy Formula



  • SLE is the Single Loss Expectancy ($)
  • AV is the asset value ($)
  • EF is the exposure factor

To calculate Single Loss Expectancy, multiply the asset value by the exposure factor.

How to Calculate Single Loss Expectancy?

The following steps outline how to calculate the Single Loss Expectancy.

  1. First, determine the asset value ($). 
  2. Next, determine the exposure factor. 
  3. Next, gather the formula from above = SLE = AV * EF.
  4. Finally, calculate the Single Loss Expectancy.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

asset value ($) = 500,000

exposure factor = 0.75
