Enter the flat rate hours produced and the actual hours worked into the calculator to determine the Flat Rate Efficiency. 

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:

  1. First, determine the flat rate hours produced. In this example, the flat rate hours produced is given as 8.
  2. Next, determine the actual hours worked. For this problem, the actual hours worked is given as 10.
  3. 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
