THE BASICS
What is ROAS?
Return on Ad Spend (ROAS) tells you how much revenue you generate for every unit of currency you spend on advertising. It's the single most common metric for judging whether an ad campaign is working.
A ROAS of 4 (written as 4x, 4:1, or 400%) means you earned $4 in revenue for every $1 spent on ads. ROAS is a ratio of revenue to cost — it does not, on its own, tell you whether you made a profit. For that you need your break-even ROAS, which factors in your profit margin.
| Metric | ROAS | ROI |
|---|---|---|
| Formula | Revenue ÷ Ad Spend | (Revenue − Cost) ÷ Cost × 100 |
| Costs included | Ad spend only | All costs (COGS, fulfillment, overhead) |
| Answers | "How efficient is this ad spend?" | "Did this activity actually make money?" |

BENCHMARKS
What's a good ROAS?
A commonly cited starting point for ecommerce is 3:1 or higher, but the ROAS you actually need depends on your profit margin and channel. Recent industry benchmark reports put median ROAS roughly as follows:
Figures are rough medians from public industry ad-benchmark reports and vary widely by vertical, seasonality and funnel stage — use them as a reference point, not a target. Your own break-even ROAS (see the calculator above) is the number that actually matters for profitability.
QUESTIONS
Frequently asked questions.
Divide the revenue your ads generated by how much you spent on those ads: ROAS = Revenue from Ads ÷ Ad Spend. For example, $4,000 in revenue from $1,000 in ad spend is a ROAS of 4 (written as 4x, 4:1, or 400%) — you earned $4 in revenue for every $1 spent. Use the quick calculator above to work this out automatically.
There's no single universal number. A commonly cited rule of thumb is 3:1 for ecommerce, but the ROAS you actually need to be profitable is your break-even ROAS — 1 ÷ your profit margin. A business with a 20% margin needs a 5x ROAS just to break even; a business with a 50% margin only needs 2x.
Break-even ROAS = 1 ÷ Profit Margin (as a decimal). If your profit margin is 25%, your break-even ROAS is 1 ÷ 0.25 = 4. Anything above 4x is profit; anything below it is a loss once product and fulfillment costs are counted. Enter your margin in the calculator above to see this automatically.
ROAS only weighs revenue against ad spend. ROI weighs profit against total investment, including cost of goods, fulfillment and overhead — not just ad spend. ROAS tells you how efficient the advertising itself is; ROI tells you whether the underlying business activity was actually profitable.
Not in the basic formula, which uses gross revenue. For an accurate number, use net revenue — after discounts, minus refunds. The campaign table above has dedicated Discounts and Refunded columns so its Total and ROAS reflect real, net performance rather than gross sales.
Not necessarily. A very high ROAS on a tiny budget can mean you're under-investing in growth, while a lower ROAS on a much larger budget can generate far more total profit. Judge ROAS together with total spend and total profit, not as a single isolated number.
