Return on ad spend (ROAS) is the first number most founders look at in Meta Ads Manager. It’s simple: revenue from ads divided by what you spent on them. Spend ₹1 lakh, make ₹3.5 lakh, and your ROAS is 3.5x.
The problem is that ROAS on its own doesn’t tell you whether you made money. Here’s how we read it for the D2C brands we work with.
1. Start with your break-even ROAS
Before you can call a ROAS “good”, you need to know the ROAS at which you stop losing money. It depends on your gross margin after product cost, shipping, payment fees and returns.
A simple way to estimate it: break-even ROAS = 1 ÷ contribution margin. If you keep 40% of every order after those costs, your break-even ROAS is 1 ÷ 0.40 = 2.5x. Anything below that loses money on the first order; anything above it is profit you can reinvest.
2. Look at platform ROAS and blended ROAS together
Meta and Google each report the sales they believe they caused. Add them up and they often claim more revenue than your store actually made. That’s normal — each platform counts a sale it touched.
So we always check blended ROAS (sometimes called MER): total store revenue divided by total ad spend across every channel. Platform ROAS tells you which campaigns to scale. Blended ROAS tells you whether the business is growing.
3. Check the tracking before the number
A ROAS is only as good as the tracking behind it. Missing Conversions API events, duplicate purchases or a broken GA4 setup can make a campaign look much better — or much worse — than it is. That’s why every engagement we start includes a tracking audit of the Meta Pixel, Conversions API and GA4.
4. Don’t forget the second order
First-order ROAS ignores what happens next. If a meaningful share of customers come back and buy again, a campaign that only breaks even on the first order can be very profitable over a few months.
This is where retention marketing changes your maths: good WhatsApp and email flows raise lifetime value, which lets you afford a lower first-order ROAS and outbid competitors for the same customers.
5. Judge creatives, not just campaigns
ROAS usually drops when creatives get tired. Before you cut budgets or rebuild campaigns, check frequency and creative performance. Fresh hooks, formats and angles — tested every week — are often the fastest fix.
A quick checklist
- Know your break-even ROAS and target ROAS before you launch.
- Review blended ROAS every week, platform ROAS every day.
- Fix tracking first — Pixel, Conversions API and GA4.
- Factor in repeat purchases when you set targets.
- Refresh creatives before you blame the algorithm.
