Enter the total array capacity, the gained capacity, and the lost capacity into the Storage Efficiency Calculator. The calculator will evaluate the Storage Efficiency.

## Storage Efficiency Formula

The following formula is used to calculate the Storage Efficiency.

**SE = (TAC + GC – LC )/ TAC * 100**

Variables:

- SE is the Storage Efficiency (%)
- TAC is the total array capacity
- GC is the gained capacity
- LC is the lost capacity

## How to Calculate Storage Efficiency?

The following steps outline how to calculate the Storage Efficiency.

- First, determine the total array capacity.
- Next, determine the gained capacity.
- Next, determine the lost capacity.
- Next, gather the formula from above = SE = (TAC + GC – LC )/ TAC * 100.
- Finally, calculate the Storage Efficiency.
- 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.

total array capacity = 500

gained capacity = 30

lost capacity = 400

SE = (TAC + GC – LC )/ TAC * 100 =** ** ?
