The formula to calculate the Cost Per Sale (CPS) is:
\[ \text{CPS} = \frac{\text{TC}}{\text{TS}} \]
Where:
Let's say the total cost (TC) is $500 and the total number of sales (TS) is 50. Using the formula:
\[ \text{CPS} = \frac{500}{50} = 10 \, \text{\$/sale} \]
So, the cost per sale is $10 per sale.
