What ROAS is and how to calculate it
ROAS stands for Return on Ad Spend. The formula is simple:
ROAS = Revenue generated by ads ÷ Ad spend
Example: $8,000 in revenue ÷ $2,000 spent = ROAS of 4 (or 400%)
A ROAS of 4 means that for every $1 spent on ads, $4 came back in revenue. Whether that ROAS actually covers your costs depends on your margin.
What counts as a good ROAS for your business?
High-margin businesses (like consulting or clinics) can be profitable with a ROAS of 2. Low-margin businesses (like retail) may need a ROAS of 6 or more to cover all their costs.
High ROAS but no profit: how that happens
A ROAS of 5 sounds great, but if your net margin is 15%, you need a ROAS above 6.7 just to break even. ROAS doesn't factor in fixed costs, commissions, shipping, or discounts. That's why the more complete metric is profit-based ROAS, which factors in all operating expenses, not just ad spend.
Serious agencies work with the business owner to understand margin and set the minimum ROAS worth investing in, and they pause the campaign if that number isn't being hit.
Frequently asked questions
Are ROAS and ROI the same thing?
No. ROAS only looks at revenue generated versus ad spend. ROI (Return on Investment) factors in all business costs: product, shipping, labor. ROAS is a slice of ROI.
My agency doesn't show me ROAS. Is that normal?
It depends on the business model. For e-commerce, ROAS is tracked automatically. For services (where the sale happens by phone or in person), calculating ROAS requires call tracking and follow-up on closed deals. Any serious agency should be trying to do this.
Can I improve ROAS without increasing the budget?
Yes. Improving the landing page, the ad itself, and audience targeting increases ROAS without touching the budget. Campaign optimization can double the return before any spending increase.
