ROAS (Return on Ad Spend)
The short answer
ROAS (Return on Ad Spend) is the revenue generated for every rupee spent on advertising. Divide the revenue attributed to your ads by what you spent on them: ₹5,00,000 in revenue from ₹1,25,000 in spend is a 4.0x ROAS.
It's the most quoted number in performance marketing and the most misleading one on its own, because revenue isn't profit. A 4x ROAS is excellent at 70% gross margin and loss-making at 20%.
How to calculate it
ROAS = Revenue from ads ÷ Ad spend
Expressed as a multiple (4.0x) or a percentage (400%). Both mean the same thing.
Why ROAS alone tells you nothing
ROAS answers "how much revenue did the ads make?" — not "did we make money?". To know that, compare it against your break-even ROAS, which is 1 ÷ gross margin.
At 50% gross margin, break-even is 2.0x. A campaign at 2.5x is profitable. At 25% margin, break-even is 4.0x — and that same 2.5x campaign loses money on every order.
What a good ROAS looks like
- Above your break-even ROAS, with enough headroom to cover fixed costs — that's the only universal answer
- Prospecting ROAS is lower than retargeting ROAS by design; that's not a failure, it's the funnel working
- Blended ROAS (MER) matters more than campaign ROAS as you scale
- Falling ROAS with rising profit can be the correct trade when you're scaling volume
Common ROAS mistakes
- Adding Meta's reported revenue to Google's — both often claim the same sale
- Comparing your ROAS to a competitor's without knowing their margin structure
- Optimising to maximise ROAS, which shrinks you toward retargeting-only spend
- Ignoring returns and RTO, which inflate revenue that never lands
- Judging a new prospecting campaign on the same ROAS target as brand search
ROAS vs ROI vs MER
ROAS benchmarks: why they mislead
Published "average ROAS" figures mix businesses with very different margins, attribution settings and order values. A 3x ROAS is profitable at a 50% contribution margin (break-even 2x) and loss-making at 25% (break-even 4x). Compare your ROAS with your own break-even, calculated with the break-even ROAS calculator, and track MER for the blended picture.
ROAS in practice: a worked example
A D2C brand spends ₹2,00,000 on Meta in a month and Meta reports ₹7,00,000 in purchases: a 3.5x platform ROAS. But 15% of orders are cancelled or returned, and Google also claims some of the same sales. Delivered, deduplicated revenue attributable to Meta is closer to ₹5,50,000 — a real ROAS of about 2.75x. With a break-even ROAS of 2.5x, the campaign is still profitable, but with far less headroom than the dashboard suggested.
ROAS by channel and campaign type
| Campaign type | Typical ROAS pattern | Why |
|---|---|---|
| Brand search | Very high | People already know you; partly non-incremental |
| Retargeting | High | Warm audiences; partly non-incremental |
| Shopping and Performance Max | Medium to high | Mix of new and existing demand |
| Prospecting (Meta, YouTube) | Lower | Reaches new customers; more incremental |
| Marketplace ads | Varies | Depends on organic rank and competition |
How to improve ROAS
- Raise conversion rates with faster, clearer landing pages
- Increase AOV with bundles and thresholds
- Refresh creative before fatigue sets in
- Exclude existing customers from prospecting where appropriate
- Cut placements and audiences that spend without converting
ROAS in India
Indian advertisers face COD returns, festive auction spikes and marketplace overlap, all of which distort platform ROAS. Reporting ROAS on delivered revenue, comparing it against break-even ROAS and tracking blended MER gives a truer picture.
How to report ROAS honestly
- Use delivered revenue, not ordered revenue, where returns and cancellations are significant.
- Separate brand and non-brand campaigns.
- Compare each channel's ROAS against break-even ROAS.
- Check the total against blended MER from your own data.
- Run periodic holdout tests to confirm incrementality.
ROAS targets by business situation
| Situation | Typical approach to ROAS targets |
|---|---|
| New brand finding product-market fit | Accept lower ROAS while learning; cap total spend |
| Profitable growth phase | Target ROAS above break-even with room for fixed costs |
| High repeat-purchase business | Allow lower first-order ROAS when LTV justifies it |
| Clearance or cash-flow focus | Prioritise higher ROAS and faster payback |
| Brand-building periods | Judge upper-funnel spend on lift, not ROAS alone |
ROAS vs MER vs CAC: which to use when
- ROAS — daily and weekly campaign optimisation within a platform
- MER — weekly and monthly check on overall marketing efficiency
- CAC — planning budgets and judging new-customer acquisition
- LTV:CAC — deciding how much you can afford to spend to acquire customers
A short history of ROAS
ROAS became the default advertising metric as search and social platforms began reporting revenue alongside spend. Its popularity comes from simplicity; its weakness is that it reflects platform attribution rather than business profit — which is why mature advertisers pair it with break-even ROAS, MER and incrementality testing.
ROAS for different platforms
Google Ads
Google reports conversion value divided by cost. Smart Bidding can target a ROAS directly (target ROAS), but needs enough conversion data with accurate values. Brand search campaigns usually show the highest ROAS, partly because those customers were already looking for you.
Meta Ads
Meta reports purchase ROAS using its attribution setting — commonly seven-day click and one-day view. Because view-through conversions are included, Meta's ROAS can overlap with other channels. Compare it with delivered revenue and blended MER.
Amazon and marketplaces
Marketplaces usually report ACoS (the inverse of ROAS) on ad-attributed sales. Total advertising cost of sale (TACoS) shows whether ads are also lifting organic sales.
YouTube and upper-funnel video
Video campaigns often show low last-click ROAS while still driving branded searches and later sales. Judge them with lift studies, branded-search trends and incrementality tests rather than ROAS alone.
Why ROAS falls as you scale
Every audience has a limit. The first rupees reach the people most likely to buy; additional spend reaches progressively less interested people, so ROAS usually declines as budgets grow. That's not automatically a problem — total profit can still rise. The right question is whether the marginal (next) rupee earns more than it costs, not whether average ROAS stays high.
ROAS checklist for marketers
- Know your break-even ROAS for each product or category
- Report delivered, deduplicated revenue
- Separate brand, retargeting and prospecting
- Track blended MER weekly
- Test incrementality before major budget changes
ROAS examples by business type
eCommerce: ₹3,00,000 revenue from ₹75,000 spend = 4.0x ROAS. With a 40% contribution margin, break-even is 2.5x, so the campaign is profitable.
Lead generation: 100 leads from ₹50,000 spend; 10 become customers worth ₹25,000 each = ₹2,50,000 revenue, a 5.0x ROAS — but only when revenue is tracked back to the original ads.
Marketplace: ₹1,00,000 ad-attributed sales on ₹20,000 spend = 5.0x ROAS, or 20% ACoS.
App: ₹40,000 spend producing first-month subscription revenue of ₹60,000 = 1.5x first-month ROAS; lifetime revenue determines whether that's acceptable.
ROAS and attribution windows
The same campaign can report very different ROAS depending on the attribution window — for example, one-day versus seven-day click, or whether view-through conversions are counted. Longer windows and view-through credit raise reported ROAS. When comparing campaigns or platforms, make sure the windows match, and treat view-through conversions cautiously.
ROAS and discounts
Discounts raise conversion rates but lower revenue per order, and they change break-even ROAS because margin shrinks. A sale that doubles orders at 30% off can still lower profit. Always recalculate break-even ROAS for promotional periods.
Frequently asked questions
What is a good ROAS in India?
There is no single number. Compare against your break-even ROAS: 1 ÷ gross margin. A 65%-margin brand breaks even near 1.5x; a 30%-margin brand needs about 3.3x.
Is a higher ROAS always better?
No. Pushing ROAS higher usually means spending less on prospecting, which shrinks the business. Past break-even, growing total contribution matters more than the ratio.
Why doesn't my Shopify revenue match my Ads Manager ROAS?
Because platforms use their own attribution windows and claim conversions they influenced. Reconcile against your store or CRM using blended MER.
How do I calculate ROAS?
Divide revenue from ads by ad spend. ₹3,00,000 revenue from ₹1,00,000 spend is a 3x ROAS. Use the ROAS calculator.
Should ROAS use placed or delivered orders?
Delivered orders give a truer picture, especially with COD and returns.
Can ROAS be negative?
No — ROAS is revenue divided by spend, so it's zero or positive; it's ROI that can be negative.
Should we report ROAS on ordered or delivered revenue?
Delivered revenue is more honest for businesses with COD returns and cancellations.
Is ROAS the same as ROI?
No — ROAS uses revenue; ROI uses profit after all costs.
Why is my Google ROAS higher than my Meta ROAS?
Google often captures existing demand (including brand searches), while Meta creates new demand — so Google's ROAS can look higher even when Meta drives growth.
Can ROAS be calculated for offline sales?
Yes, if offline sales are matched to ad exposure — for example through offline conversion imports or store-visit measurement.
What ROAS do Indian D2C brands typically need?
It depends on margins and returns; many need well above 2x to be profitable after COD returns and discounts — calculate yours with the break-even ROAS calculator.
What's the difference between ROAS and conversion value per cost?
They're the same idea — Google Ads labels it "conversion value / cost".
Does a falling ROAS mean campaigns are failing?
Not necessarily — as spend scales, average ROAS often falls while total profit rises. Check marginal returns and overall profit.
Is ROAS useful for brand campaigns?
Only partly — brand campaigns are better judged with lift, branded search and long-term sales trends.
Should ROAS include shipping revenue?
Be consistent — many businesses exclude shipping and taxes so ROAS reflects product revenue.
