What is a good ROAS?
There is no universal good ROAS. A good ROAS is any return above your break-even ROAS, which is 1 divided by your gross margin, with enough room left to cover overhead and the profit you want to keep. At a 40% margin your break-even is 2.5x, so a genuinely good ROAS sits comfortably above it, often 3x to 5x or higher. The “aim for 4x” advice you see everywhere is a guess that ignores the one number that actually decides it: your margin.
Set your numbers. Your break-even and your good target update live.
Why “2x to 4x is good” is a myth
The same ROAS can be excellent for one brand and bankrupting for another, because the only thing that decides it is margin. A 4x ROAS keeps 75% of revenue against ad cost. If your real margin is 70%, that 4x is hugely profitable. If your real margin is 25%, that same 4x loses money on every order before you have paid a cent of overhead.
Break-even is 1.4x, so 4x leaves a wide profit cushion.
Break-even is 4.0x, so 4x makes zero before overhead.
Start with your break-even ROAS
Your break-even ROAS is 1 divided by your real gross margin. It is the return where an order makes exactly zero profit before overhead. Below it, every sale loses money. It is the floor, not the target.
| Real gross margin | Break-even ROAS |
|---|---|
| 20% | 5.00x |
| 25% | 4.00x |
| 30% | 3.33x |
| 40% | 2.50x |
| 50% | 2.00x |
| 60% | 1.67x |
| 70% | 1.43x |
From break-even to a target worth setting
A good ROAS is your break-even plus the overhead and profit you want on top. The math is one line:
share for ads = real margin % − overhead % − net target % target ROAS = 1 ÷ share for ads
At a 44% margin with 15% overhead and a 12% net target, 17% of revenue is left for ads, so your target ROAS is 5.9x. The break-even floor underneath it is 2.27x. The space between 2.27x and 5.9x is your cushion, and it is exactly what the calculator works out per product from your own numbers.
A good ROAS by industry
Because margins differ by category, so does the break-even every good ROAS has to clear. A snapshot, from our sourced benchmarks:
| Industry | Typical real margin | Break-even ROAS |
|---|---|---|
| Apparel / fashion | 55% | 1.82x |
| Beauty / cosmetics | 72% | 1.39x |
| Supplements / CPG | 70% | 1.43x |
| Electronics | 35% | 2.86x |
| Home / furniture | 42% | 2.38x |
| Jewelry & accessories | 60% | 1.67x |
Is a higher ROAS always better?
No, and this is where most teams leave money on the table. A very high ROAS usually means you are underspending: you have found a small pocket of cheap demand and stopped. The goal is not the biggest ratio, it is the lowest ROAS that still hits your profit target, because that is the point where you can pour in budget and grow volume while staying profitable. Chasing a high ROAS shrinks the business; hitting your target ROAS at scale grows it.
Frequently asked questions
What is a good ROAS?
There is no universal good ROAS. A good ROAS is any return above your break-even ROAS, which is 1 divided by your real gross margin, with enough room left to cover overhead and the profit you want to keep. At a 40% margin your break-even is 2.5x, so a good ROAS sits comfortably above that. Your margin sets the number, not a rule of thumb.
What is a good ROAS for ecommerce?
Most ecommerce brands run real gross margins of 30% to 70%, so break-even ROAS lands between about 1.4x and 3.3x. A good target sits above that once overhead and profit are covered, commonly 3x to 6x. Lower-margin categories like electronics need a higher ROAS than high-margin ones like beauty or supplements.
What is a good ROAS for Facebook (Meta) ads?
Meta reports ROAS on its own attribution, which usually overstates new-customer revenue, so measure against your break-even ROAS on a 7-day-click window. A good Meta ROAS is one that clears your break-even with margin to spare. For a typical 40% margin that is roughly 3x or higher.
What is a good ROAS for Google Ads?
The rule is the same as Meta: compare to your break-even ROAS, not a fixed number. Google search and shopping often harvest warmer demand, so a good blended ROAS can run higher. Set your target ROAS bid to 1 divided by the share of revenue you can spend on ads.
What is a good ROAS on Amazon?
Amazon sellers usually track ACoS, the inverse of ROAS. A good ROAS still depends on margin: break-even ROAS is 1 divided by your margin, and a good ROAS clears it after Amazon fees. For many sellers that means 3x to 5x or more.
What is a good ROAS percentage?
ROAS is usually written as a ratio, like 4x, but sometimes as a percentage, like 400%. They mean the same thing: four dollars back for every one spent. A good ROAS percentage is anything above your break-even, which is 100 divided by your margin percent.
What is the difference between ROAS and break-even ROAS?
ROAS is what your ads return today. Break-even ROAS is the floor: 1 divided by your gross margin, the return at which an order makes zero profit before overhead. A good ROAS is above break-even, and your target ROAS adds overhead and your profit margin on top of the floor.
Is a higher ROAS always better?
No. A very high ROAS often means you are underspending and leaving growth on the table. The goal is the lowest ROAS that still hits your profit target, so you can scale volume. Profit dollars matter more than the ratio.
Your real margin, returns and overhead, worked backwards to the exact target to set in Meta.
