Is your ad spend
actually profitable?
ROAS on its own tells you nothing. What matters is the ROAS your margin needs. Put your numbers in and see both.

Your ROAS

Estimates from the figures you entered. Treat them as a directional model of your own economics, not an audited result.
What ROAS actually means
ROAS is return on ad spend: the revenue attributed to your advertising divided by what you spent to get it. A ROAS of 3× means every ₹1 of spend brought back ₹3 of revenue.
The number everyone quotes is revenue-based, which is why it is so easy to misread. Revenue is not profit. A 3× ROAS is excellent on a 60% margin product and a straight loss on a 25% margin one.
Break-even ROAS is the number that matters
Break-even ROAS is the point where the gross profit from ad-driven revenue exactly covers the ad spend. Below it you are buying revenue at a loss, however healthy the headline looks.
e.g. at 40% margin → 1 ÷ 0.40 = 2.5×
This is the single most useful thing to know before a sale or a scaling push. If your margin is 40%, any campaign under 2.5× is costing you money to run, and the fix is margin or targeting, not more budget.
ROAS and ACOS are the same thing, inverted
ACOS (advertising cost of sale) is ad spend as a percentage of revenue. If ROAS is 4×, ACOS is 25%. Marketplaces tend to speak in ACOS, ad platforms in ROAS. Neither changes the underlying maths.
Why RTO quietly destroys your real ROAS
Ad platforms count an order the moment it is placed. If a fifth of your cash-on-delivery orders come back undelivered, the platform still reports that revenue, but you never collected it — and you paid freight both ways on top. Reported ROAS looks fine while delivered ROAS is materially worse.
To get an honest figure, multiply your reported ROAS by your delivery rate. At 4× reported and a 75% delivery rate, your real ROAS is 3×. Work out what that gap costs you with the RTO cost calculator.
Frequently asked questions
What is a good ROAS for a D2C brand in India?
There is no universal number, because it depends entirely on gross margin. A brand at 60% margin breaks even at roughly 1.7×, so 3× is genuinely profitable. A brand at 25% margin breaks even at 4×, so the same 3× is losing money. Calculate your break-even first, then judge campaigns against that rather than against a benchmark you read somewhere.
How do I calculate break-even ROAS?
Divide 1 by your gross margin expressed as a decimal. At 40% margin that is 1 ÷ 0.40 = 2.5×. Anything above that adds gross profit; anything below subtracts it. If you want to cover fixed costs too, raise the target above break-even rather than sitting on it.
Is ROAS the same as ROI?
No. ROAS measures revenue against ad spend only. ROI measures profit against total investment, including cost of goods, fulfilment, salaries and everything else. A campaign can have strong ROAS and negative ROI.
Why is my blended ROAS lower than my platform ROAS?
Platforms attribute generously and often claim the same conversion more than once. Blended ROAS — total revenue divided by total marketing spend — is the honest version, and it is almost always lower. Use platform ROAS to compare campaigns against each other, and blended ROAS to decide how much to spend overall.
Does a return count against ROAS?
Not in the platform reporting, no. The platform books the conversion at checkout. Returns and undelivered COD orders come out of your bank account, not out of the dashboard. This is why brands with high RTO consistently overestimate how well their advertising is performing.
