Enter the total spent ($) and the total number of outcomes achieved into the calculator to determine the Cost Efficiency. 

Cost Efficiency Calculator

Measure cost efficiency as both cost per unit and output per dollar. You can also compare two options to see which one is more cost efficient.

Optional. Use this to estimate improvement versus a previous period or target.

Cost Efficiency Formula

The following formula is used to calculate the Cost Efficiency. 

Ecost = TS / O
  • Where Ecost is the Cost Efficiency ($/outcome)
  • TS is the total spent ($) 
  • O is the total number of outcomes achieved 

to calculate the cost efficiency, divide the total amount spent by the total number of outcomes achieved.

How to Calculate Cost Efficiency?

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

Example Problem #1:

  1. First, determine the total spent ($). In this example, the total spent ($) is given as 100.
  2. Next, determine the total number of outcomes achieved. For this problem, the total number of outcomes achieved is given as 4.
  3. Finally, calculate the Cost Efficiency using the equation above: 

Ecost = TS / O

Inserting the values from above and solving the equation: 

Ecost = 100 / 4 = 25 ($/outcome)


Example Problem #2: 

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

total spent ($) = 500

total number of outcomes achieved = 6

Entering these values yields:

Ecost = 500 / 6 = 83.33 ($/outcome)
