ROAS Calculator — Return on Ad Spend
Find out how much revenue you earn for every dollar spent on advertising. ROAS is the primary efficiency metric for paid digital marketing campaigns.

¿Cómo funciona esta calculadora?
ROAS = ad-attributed revenue ÷ ad spend. A 4× ROAS means $4 earned per $1 spent. Break-even ROAS = 1 ÷ gross margin (e.g. 4× for a 25% margin). Unlike ROI, ROAS ignores product cost — always check gross profit after COGS to confirm actual campaign profitability.

How this is calculated
Return on Ad Spend (ROAS) measures how many dollars of revenue a campaign generates for each dollar of advertising cost. A ROAS of 4× means the campaign generated $4 in revenue for every $1 spent. Unlike ROI (which measures profit), ROAS measures gross revenue return without subtracting product costs — so a 4× ROAS on a product with 80% COGS would actually be unprofitable. For that reason this calculator also accepts cost of goods sold (COGS) so you can see the true gross profit after both product cost and ad spend.
The break-even ROAS is the minimum ratio at which ad spend pays for itself in revenue — trivially, it is always 1× (revenue = spend). The meaningful break-even includes COGS: if your gross margin is 40% (COGS 60% of revenue), you need at minimum ROAS = 1 ÷ gross-margin-fraction = 2.5× just to cover costs before paying for other overhead. Any ROAS below this produces a loss on each ad-attributed sale.
Run ROAS by campaign, ad group, keyword, or product to identify what is working. Google Ads and Meta report ROAS as "conv. value ÷ cost" — this is the same calculation. Note that attribution models (last-click, data-driven, view-through) significantly affect what revenue is counted as "from ads"; compare ROAS consistently within the same attribution window.

A common starting benchmark is 4× (400% ROAS) for e-commerce, meaning $4 revenue per $1 spent. However, the required ROAS depends entirely on your gross margin. If your gross margin is 25%, you need ROAS ≥ 4× to break even on product cost alone, before overhead. Higher margins allow profitable operation at lower ROAS. Calculate your own break-even ROAS as 1 ÷ gross margin fraction.
ROAS = revenue ÷ ad spend (a gross revenue ratio). ROI = profit ÷ cost (a net profit ratio). ROAS ignores product cost; ROI includes it. A campaign with 4× ROAS on products with 60% COGS has an ROI of (4 − 1 − 2.4) ÷ 1 = 60%, while a campaign with the same 4× ROAS on 80% COGS has an ROI of (4 − 1 − 3.2) ÷ 1 = −20% — a loss. Always check both metrics.
Use ROAS when the revenue value of each conversion varies (e.g. variable order values in e-commerce). Use CPA (or cost per lead) when conversions have a fixed or estimated lifetime value and you want to stay below a target acquisition cost. Many businesses use both: ROAS for campaign optimisation, CPA to ensure profitability when margins vary by product.
