Enter the spare capacity and the total capacity into the Capacity Cushion Calculator. The calculator will evaluate the Capacity Cushion. 

Capacity Cushion Formula

The following two example problems outline the steps and information needed to calculate the Capacity Cushion.

CC = SC / TC * 100


  • CC is the Capacity Cushion (%)
  • SC is the spare capacity 
  • TC is the total capacity 

To calculate the capacity cushion, divide the spare capacity by the total capacity.

How to Calculate Capacity Cushion?

The following steps outline how to calculate the Capacity Cushion.

  1. First, determine the spare capacity. 
  2. Next, determine the total capacity. 
  3. Next, gather the formula from above = CC = SC / TC * 100.
  4. Finally, calculate the Capacity Cushion.
  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.

spare capacity = 100

total capacity = 200

CC = SC / TC * 100 = ?
