Frequently asked questions

What is ROAS?
ROAS (Return on Ad Spend) measures how much revenue you earn for every dollar spent on ads. Your campaigns make a profit only when ROAS is above your break-even ROAS: 100 divided by your margin before ad costs.
Why is ROAS important?
ROAS helps determine your ad campaign's success. A ROAS of 1 (100%) only pays back the ad spend: product cost and Amazon fees still come out of those sales. Compare ROAS with your break-even ROAS instead.
How is ROAS calculated?
The formula: ROAS = (Revenue from Ads / Cost of Ads) x 100. Our calculator runs the math instantly.
Can I use this tool for non-Amazon campaigns?
Absolutely! While designed with Amazon PPC in mind, you can apply it to measure the performance of other paid ad campaigns as well.
Is it really free?
Yes. No hidden costs. No signup.
