## 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

## How to Calculate Cost Efficiency?

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

**Example Problem #1:**

- First, determine the total spent ($). In this example, the total spent ($) is given as 100.
- Next, determine the total number of outcomes achieved. For this problem, the total number of outcomes achieved is given as 4.
- 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 = 30 ($/outcome)
