Someone online says 4x. Someone else says anything under 3x is trash. A third person says they run profitably at 1.4x. They're all right, and they're all wrong, because a "realistic ROAS" doesn't exist. There's only your break-even, and everything above it.
The number depends entirely on your margin
A brand selling a product at 70% gross margin can profit at a 1.5x ROAS. A brand at 30% margin needs 3.3x just to break even. Same ROAS, opposite outcomes. So when someone tells you a "good" ROAS, ask what their margin is. Without that, the number means nothing.
Run both so it actually sinks in. Break-even is 1 divided by margin. At 70%, that's 1 divided by 0.7, about 1.43x. So 1.5x is above the line, small but real profit on every order. At 30%, break-even is 3.33x, and 1.5x means you lose roughly Rs.550 on every Rs.1,000 of spend, every time, no matter how the dashboard celebrates. Identical ROAS, one business quietly making money, the other quietly dying.
This is why e-commerce founders keep arguing past each other. One is running high-margin supplements and thriving at 2x. The other is running low-margin fashion and drowning at 3x. They're both quoting real numbers from real businesses that just have completely different economics. Neither picture applies to yours until you know your own margin.
What the wide market actually sees
Across most e-commerce accounts, blended MER, total revenue over total ad spend, tends to land somewhere between 1.5x and 3x at scale. Below 1.5x most businesses can't cover product costs and overhead. Above 3x usually means you're under-spending and leaving growth on the table, not that you're a genius.
Why 3x at the top and not 5x? Because spending more always drags efficiency down. The 4x and 5x accounts you see are almost always small, sitting on the cheapest layer of their market. Scale them and the same arithmetic that hits everyone catches up. A mature, genuinely scaled account rarely holds much above 3x blended, and that's fine. That range, at a healthy margin, prints money.
But those are broad ranges, not targets. Your target is your break-even ROAS plus whatever cushion your profit goal needs. If profit after ads and overhead matters to you, set the target with an overhead line inside it, not just gross margin. A business can clear first-order break-even and still starve on rent.
Why the myth persists
Because ROAS is easy to screenshot and share, and profit isn't. A 12x ROAS screenshot gets attention. A 1.6x acquisition MER that's actually profitable doesn't look impressive, so nobody posts it, and new founders chase numbers that were never achievable for their margins in the first place.
There's a selection effect on top of that. The people most likely to post their ROAS are the people with a high one, which means the internet's average "realistic" ROAS is a survival-biased sample, not a market average. It's like judging normal salaries from a car showroom.
And the same screenshot hides the levers. That 12x account might have a 75% margin, a Rs.300 average order, and no real competitor in sight. Or it might count every order that ever glanced at an ad. You can't tell from the picture, which is the whole point of the picture.
"So what should MY number be?"
Straight answer, and the closest thing to a rule I'll give you:
- Calculate your true gross margin, COGS plus shipping, fees, packaging, and an honest returns reserve.
- Divide 1 by that margin. That's your break-even ROAS, the floor.
- Add your profit cushion above the floor. If break-even is 2.5x and you want a real business after ads, your acquisition target is maybe 3x, not 5x.
From there the market range helps you read yourself. If your break-even is 2.5x, then 3x is a healthy ROAS for you and 5x is exceptional. If your break-even is 1.6x, then 2.2x is strong and you should be scaling, not chasing a 5x that would require luck. If you sit in the middle at a 2x break-even, 2.5x to 3x is your working zone.
One more thing worth saying. If your break-even is 4x because your margin is 25%, no ROAS target fixes that. The problem is upstream of the ads, in pricing, product cost, or the product itself. Founders burn years trying to out-bid bad unit economics. Ads can only work with the margin you hand them.
Don't forget overhead sits above the floor
One more layer before you call 3x "good." Break-even from gross margin covers the product and its delivery costs. Rent, salaries, tools, and handling all come out of whatever is left. Run one full check a year at least: take an actual month, real revenue, real ad spend, real overhead from your books, and see what the business kept after everything. If your break-even is 2.5x and you operate at 3x, spending Rs.1,000 brings Rs.3,000 of revenue and Rs.1,200 of gross profit at that margin; overhead at 15% of revenue takes Rs.450, leaving Rs.750. Still profitable, but half as thick as the raw ratio suggested, and thinner margins have thinner tolerance for a bad quarter. I've watched founders scale into exactly that gap, profitable on paper every month, squeezed at bank level, because the target was set against gross margin and never re-set against running costs. Once you know your operating number, your "realistic ROAS" gets a second floor, and the floor is the honest one.
Stop asking what a realistic ROAS is. Ask what your break-even is. Then everything above that line is yours, and you know exactly where the floor sits.
