An ad campaign can look busy and still lose money once its cost is divided across the sales it brings in.
Turn ad spend, the sales it brings, and your profit per sale into a cost per sale, a net result, and a break-even sales count.
Small sellers and freelancers who run paid ads and want the cost per sale in plain numbers.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Add up what you paid for the campaign in the period. Include the boosting fees the platform charged.
Count the sales you can reasonably tie to the campaign. Write down how you counted them.
Subtract the cost of goods, fees, and shipping from the price. Use the profit left per sale.
Divide the spend by the sales. Compare that cost with the profit each sale leaves.
Advertising claims must be truthful and substantiated. Check the FTC business guidance before you change any ad copy.
You spend $500 on ads and get 20 sales at $40 profit each. The cost per sale is $25, the net is $300, and you need 13 sales to break even.
Use your own source and details. The example is not a record about a real person or organization.
