Pro Tips from Top Advertisers
What is a good ROAS?
A good ROAS depends on your profit margin. Generally, 4:1 is considered good, but if your margin is 50%, you only need 2:1 to break even. Use our break-even calculator to find your specific threshold.
How do I calculate ROAS?
ROAS = Revenue from Ads / Ad Spend. For example, if you spent $1,000 on ads and generated $4,000 in revenue, your ROAS is 4:1 or 400%.
What is break-even ROAS?
Break-even ROAS is the minimum ROAS needed to cover your costs. Formula: 1 / Profit Margin. If your margin is 25%, break-even ROAS is 4:1.
Is ROAS the same as ROI?
No. ROAS measures revenue per ad dollar spent. ROI measures profit after all costs. ROAS = Revenue/Ad Spend. ROI = (Revenue - All Costs) / All Costs.
Why is my ROAS different across platforms?
Attribution models vary. Facebook uses 7-day click, 1-day view. Google uses last-click by default. This causes different platforms to 'claim' the same conversion.
