What Is a Good ROAS for Ecommerce? Break-Even by Margin
Direct Answer: What is a good ROAS? One that clears your break-even point with room for profit. Break-even ROAS equals 1 divided by your contribution margin before ad spend, so a brand with a 50% margin breaks even at 2x while a 30% margin brand needs 3.33x. A good target sits comfortably above that line.
Break-even ROAS: The ROAS at which ad spend uses up all of the margin on a sale, leaving zero profit. It equals 1 divided by contribution margin before ad spend, written as a decimal.
Why a good ROAS depends on your margin
What is a good ROAS? Founders ask it as if there were one number, usually 3x or 4x. But the same 3x ROAS can be excellent for one brand and a slow cash leak for another. The difference is margin.
If you have not worked with the metric before, our guide to what ROAS is covers the formula and the basics. This post focuses on the next question: how high it needs to be for your brand.
ROAS measures revenue per dollar of ad spend. It says nothing about what that revenue costs to deliver. A brand that keeps 70 cents of every dollar after product cost, shipping and payment fees can afford to spend far more to win a sale than a brand that keeps 30 cents. So a good ROAS is not a benchmark you borrow. It is a number you calculate from your own unit economics, then adjust for customer type, campaign type and how you measure.
Break-even ROAS by margin
Break-even ROAS is 1 divided by your contribution margin before ad spend. Contribution margin here means what is left from each sale after product cost, shipping, packaging, payment fees and discounts. At break-even, ad spend uses up all of it.
The table below is calculated, not surveyed. The last column shows the ROAS needed to keep 15% of revenue as profit after ads, which is 1 divided by (margin minus 0.15).
| Contribution margin | Break-even ROAS | Margin on a $100 order | ROAS for 15% profit after ads |
|---|---|---|---|
| 30% | 3.33x | $30 | 6.67x |
| 40% | 2.50x | $40 | 4.00x |
| 50% | 2.00x | $50 | 2.86x |
| 60% | 1.67x | $60 | 2.22x |
| 70% | 1.43x | $70 | 1.82x |
What the table tells you
Low-margin brands have very little room. At 30% margin, a 4x ROAS only just covers costs, and real profit needs well over 6x. At 60% margin, 2.5x is already healthy. If your break-even is high, raising margin through bundles, price or product cost often helps more than chasing a higher ROAS.
New vs returning customers
First-order ROAS treats every customer as worth one purchase. If customers come back, you can accept a lower ROAS on the first order and still make money over time.
Example arithmetic only: AOV is $60 and contribution margin is 50%, so each order contributes $30. First-order break-even ROAS is 2x. If customers place an average of 1.8 orders in their first year, each customer contributes $54. You could pay up to $54 to acquire them and break even over the year, which is a first-order ROAS of $60 divided by $54, about 1.11x.
That does not mean you should run at 1.11x. Repeat revenue arrives later, so you fund the gap in cash, and repeat rates are estimates until you have cohort data. Most brands set a first-order target between break-even and the full lifetime figure, and they measure ROAS on new customers separately, because returning customers inflate the blended number.
Prospecting vs retargeting ROAS
Retargeting campaigns almost always report a higher ROAS than prospecting, because they reach people who already visited your store or added to cart. Many of those people would have bought anyway, so the ad gets credit for sales it did not fully create.
Prospecting campaigns find new buyers, so their ROAS looks lower while doing more of the real growth work. If you judge both against one target, you will move budget toward retargeting, the reported ROAS will rise and new customer growth will quietly stall.
Set separate expectations. Hold prospecting to a target based on new-customer economics, keep retargeting budgets small and capped, and judge the whole account on blended results. With broad Advantage+ campaigns mixing both audiences, check the new versus existing customer split in your reporting.
Platform ROAS vs blended ROAS
Each ad platform reports the sales it believes it caused, using its own attribution window. When a shopper sees a Meta ad, then searches on Google and buys, both platforms may claim the same order. Platform ROAS added together often overstates the truth.
Example arithmetic only: Meta reports $120,000 in revenue and Google reports $50,000, a combined $170,000 on $40,000 of total spend, or 4.25x. Shopify shows $140,000 in actual revenue. Blended ROAS, also called MER, is $140,000 divided by $40,000, or 3.5x.
Use platform ROAS to compare campaigns and ads inside one platform. Use blended ROAS to decide whether the business is making money and whether to raise total budget. When the two drift apart, trust the one that matches your bank account.
What ROAS looks like in our published case studies
Across 25 published case studies with a stated ROAS, the median is 3.97x. The middle half of results sits between 3.61x and 4.39x, and the full range runs from 2.06x to 11.6x. Treat these as success-biased: brands publish good months, not bad ones, so they show what strong performance looks like rather than an industry average.
Use the figures as context, not as a target. A supplement brand at 3.9x and a dropshipping store at 11.6x tell you little about your own break-even line, because their margins, prices and repeat rates differ from yours. The useful lesson is that strong accounts across very different niches cluster around 3.5x to 4.5x on the campaigns they chose to publish, while their own margins decided whether that was a good result.
| Niche | Published ROAS range |
|---|---|
| Supplements | 3.89x to 4.51x |
| Fashion | 3.56x to 5.49x |
| Fitness | 3.61x to 4.37x |
| Skincare | 3.64x to 4.39x |
| Dropshipping | 2.53x to 11.6x |
| General DTC | 2.06x to 3.8x |
| Jewelry | 4.43x |
When a lower ROAS is the right call
A good ROAS is not always the highest one you can get. Sometimes accepting a lower number is the smarter move, as long as it is a deliberate decision with a time limit.
Launching a new product is one example. Early campaigns are buying data and reviews as well as sales, so a ROAS near break-even can be fine for a few weeks. Q4 is another: customers acquired in November can buy again in January, so brands with strong repeat rates often accept a lower first-order ROAS during the peak. Clearing old stock is a third, because recovering cash can matter more than margin.
The opposite also happens. A ROAS far above target can mean you are under-spending. If every campaign returns well above break-even, you are probably leaving profitable customers on the table, and a controlled budget increase is worth testing. Profit in dollars, not ROAS as a ratio, is what pays the bills.
How to set your own good ROAS target
Turn the ideas above into one working number in five steps.
Example arithmetic only: a brand with a $75 AOV keeps $33.75 per order after product cost, shipping, packaging and fees, a 45% margin. Break-even ROAS is 1 divided by 0.45, about 2.22x. To keep 10% of revenue as profit after ads, the target is 1 divided by 0.35, about 2.86x. That brand would treat anything under 2.2x as a loss and anything near 3x as healthy.
- Calculate contribution margin per order after product cost, shipping, packaging, payment fees and average discount.
- Find break-even ROAS as 1 divided by that margin.
- Add the profit you need after ads to get a target ROAS for first orders.
- Adjust for repeat purchases using real cohort data, not hopes.
- Track blended ROAS weekly, and raise budgets only while it stays above target.
Frequently Asked Questions
Is a 2x ROAS good for ecommerce?
It depends on margin. A brand with a 60% contribution margin breaks even at 1.67x, so 2x is profitable. A brand with a 40% margin breaks even at 2.5x, so 2x loses money on every first order. Calculate your break-even ROAS as 1 divided by your margin before judging any number.
Is a 4x ROAS good?
For most DTC brands, yes, but not all. At 50% margin, 4x leaves roughly 25% of revenue as profit after ads. At 30% margin, 4x barely clears break-even of 3.33x. It also depends on whether 4x is platform-reported or blended, since platform figures often overstate results.
What is a good ROAS for Facebook ads?
A good Facebook ads ROAS is one above your break-even line that holds when checked against blended revenue. Our published case studies have a median of 3.97x, with the middle half between 3.61x and 4.39x, but those are success-biased. Your own margin decides what counts as good for you.
Should retargeting have a higher ROAS target than prospecting?
Retargeting will naturally report a higher ROAS because it reaches people already close to buying, many of whom would buy anyway. Rather than a higher target, give it a small capped budget and judge it on incremental impact. Hold prospecting to a target based on new-customer economics.
How do I calculate break-even ROAS?
Divide 1 by your contribution margin before ad spend, written as a decimal. If each $100 order leaves $40 after product cost, shipping, packaging and fees, the margin is 0.4 and break-even ROAS is 2.5x. Our break-even ROAS calculator does the arithmetic from your own numbers.
Why is my blended ROAS lower than my Meta ROAS?
Meta, Google and other platforms each claim sales using their own attribution windows, so the same order can be counted more than once. Blended ROAS divides actual store revenue by total ad spend, which removes the double counting. A gap is normal, but a widening gap is a warning sign.
