## Flat Rate Efficiency Formula

The following formula is used to calculate the Flat Rate Efficiency.

**Efr = FR / AH**

- Where Efr is the Flat Rate Efficiency
- FR is the flat rate hours produced
- Ah is the actual hours worked

## How to Calculate Flat Rate Efficiency?

The following two example problems outline how to calculate the Flat Rate Efficiency.

**Example Problem #1:**

- First, determine the flat rate hours produced. In this example, the flat rate hours produced is given as 8.
- Next, determine the actual hours worked. For this problem, the actual hours worked is given as 10.
- Finally, calculate the Flat Rate Efficiency using the equation above:

Efr = FR / AH

Inserting the values from above and solving the equation:

Efr = 8 / 10 = .8

**Example Problem #2: **

Using the same process as above, first define the variables required by the formula. In this case, these values are:

flat rate hours produced = 11

actual hours worked = 15

Entering these values yields:

Efr = 11 /15 = .733
