Formula
How the calculation works
Revenue is the orders times the average order value, and profit subtracts both the ad spend and the cost of those orders.
ROAS is revenue per unit of ad spend, while ROI is profit as a percentage of spend, so the two answer different questions.
Cost per acquisition is the ad spend divided by orders, the simplest check on whether an ad is affordable.
Common mistakes
- Celebrating a ROAS above one while ignoring product cost, which can still leave a loss.
- Comparing ROAS across campaigns with different order values, where ROI is the fairer number.
When to use it
- Use it to check whether a paid campaign is actually making money.
- It is not a media plan; it only reads the numbers you enter for one campaign.
Worked example
Spending 10000 to get 50 orders at 500 with 200 cost each gives revenue 25000, ROAS 2.5, profit 5000 and ROI 50%.
Common questions
What is a good ROAS?
ROAS above 1 means revenue beats ad spend, but profit depends on your product cost.
What does CPA mean?
It is the ad spend divided by orders, the cost to win each purchase.
