## What is Cost per Purchase?

Cost per purchase (CPP) is a common metric used in marketing and advertising to measure the cost efficiency of campaigns. It is the total cost of an advertising campaign, divided by the number of purchases that resulted from the campaign. This metric can be used to help measure the return on investment (ROI) of a marketing strategy or campaign.

## How to Calculate Cost per Purchase

Cost per purchase is calculated by taking the total cost of an advertising campaign, including any associated costs such as ad placement, creative work, and any other expenses, and dividing it by the number of purchases that resulted from the campaign.

## Examples of Cost per Purchase

Below are some examples of cost per purchase calculations:

• Advertising campaign with a cost of \$2,000 and 20 purchases: CPP = \$2,000/20 = \$100 per purchase
• Advertising campaign with a cost of \$5,000 and 50 purchases: CPP = \$5,000/50 = \$100 per purchase
• Advertising campaign with a cost of \$10,000 and 100 purchases: CPP = \$10,000/100 = \$100 per purchase

As you can see, the cost per purchase remains the same for all of the examples, regardless of the cost of the campaign. This is because the cost of the campaign is divided evenly among the number of purchases.

## Conclusion

Cost per purchase is a commonly used metric in marketing and advertising to measure the cost efficiency of campaigns. It is calculated by taking the total cost of an advertising campaign, including associated costs, and dividing it by the number of purchases that resulted from the campaign. Understanding this metric can be beneficial in determining the return on investment (ROI) of a marketing campaign or strategy.
