Every ad platform shows you a ROAS number, and every one of them makes it look like a score. A 3.0x ROAS sounds good. A 1.8x sounds disappointing. But neither tells you whether you made or lost money, because the platform does not know what the product cost you, what you paid in marketplace fees, or what the shipping label cost. A 3.0x can be a loss and a 1.8x can be a profit; it depends entirely on your margin.
Break-even ROAS is the number that fixes this. It is the return your ads must achieve for the campaign to make exactly zero profit. Anything above it is money in your pocket; anything below it is money you paid to lose. This article shows how to calculate it, works a full example for an Etsy seller, and explains how to compare it with the figures Etsy, Meta and Pinterest report.
What ROAS means
ROAS = revenue attributed to ads ÷ ad spend. Spend $100 and the platform credits $300 of sales to those ads: ROAS is 3.0 (often written 3.0x or 300%). It is a ratio of revenue, not profit, which is exactly why it cannot tell you on its own whether the ads worked.
The break-even ROAS formula
Start with the profit you make on one order before any ad cost. Call it your contribution per order:
Contribution = order value − product cost − fees − shipping − packaging
Then:
Break-even ROAS = order value ÷ contribution
Equivalently, break-even ROAS = 1 ÷ contribution margin, where contribution margin is contribution as a percentage of order value. A 50% margin gives a break-even ROAS of 2.0; a 25% margin gives 4.0; a 20% margin gives 5.0. The thinner your margin, the harder your ads have to work.
Worked example: an Etsy seller at $40 per order
You sell a $40 print with free shipping on Etsy. Per order:
| Item | Amount |
|---|---|
| Order value | $40.00 |
| Printing and materials | $12.00 |
| Postage and mailer | $6.00 |
| Etsy transaction fee (6.5% × $40) | $2.60 |
| Etsy payment processing (3% × $40 + $0.25) | $1.45 |
| Etsy listing fee | $0.20 |
| Contribution per order | $17.75 |
Working: $40.00 − $12.00 − $6.00 − $2.60 − $1.45 − $0.20 = $17.75. Contribution margin is $17.75 ÷ $40 = 44.4%.
Break-even ROAS = $40 ÷ $17.75 = 2.25x.
Every dollar of ad spend must bring back at least $2.25 of attributed revenue, or the campaign loses money. Put another way, you can afford to pay up to $17.75 in advertising to win one order; that figure is your break-even cost per acquisition (CPA).
Now judge two example campaigns
Campaign A reports a 3.0x ROAS on $100 of spend. Revenue is $300, which at $40 each is 7.5 orders. Contribution is 7.5 × $17.75 = $133.13. Subtract the $100 spend and the campaign made $33.13 profit.
Campaign B reports a 2.0x ROAS on $100 of spend. Revenue is $200, or 5 orders. Contribution is 5 × $17.75 = $88.75. Subtract $100 and the campaign lost $11.25, even though "2x" might sound respectable.
The only thing that separated a win from a loss was knowing that 2.25 was the line. Enter your own order value and costs into the break-even ROAS calculator to find yours.
From break-even to a target
Breaking even is not the goal; you presumably want to make something. If you want to keep $8 per order after ads, your ads can only consume $17.75 − $8 = $9.75 of each order. Target ROAS = $40 ÷ $9.75 = 4.10x. That is the number to set as a goal or a bid target, not 2.25.
Turning break-even ROAS into a maximum click price
Platforms charge per click or per thousand impressions, so it helps to translate. If 2% of ad clicks turn into orders, then on average one order costs 50 clicks. Your break-even CPA of $17.75 spread over 50 clicks is $17.75 × 0.02 = $0.36 per click. Pay more than that at a 2% conversion rate and you are losing money before the sale is even made.
The Facebook ads calculator builds the whole chain from CPM and click-through rate down to sales and profit, and the Pinterest ads calculator does the same from a cost per click and also shows the conversion rate you need to break even. Both take your margin as an input, so work that out first.
Reading the numbers each platform gives you
Etsy Ads
Etsy's ad dashboard reports views, clicks, orders, revenue, spend and ROAS. Its Help Center explains that "orders are attributed to ads when someone interacts with an ad and then buys any item in your shop within 30 days." Two consequences:
- A buyer who clicked an ad on a $15 sticker and bought a $200 quilt three weeks later counts the whole $200 as ad revenue.
- Someone who would have bought anyway, but happened to click an ad first, is also counted. Etsy Ads ROAS therefore tends to flatter the ads.
Also check whether the revenue figure includes shipping you charged; the Help article does not say. If it does, your break-even calculation should use order value including shipping, too, so you are comparing like with like.
Meta (Facebook and Instagram) and Pinterest
Both platforms attribute conversions through their own tracking pixels or tags, and the attribution window (how many days after a click or view a purchase still counts) is a setting in your account. Shorter windows make ROAS look worse but more honest; longer windows and view-through attribution make it look better. Before you compare a reported ROAS with your break-even number, open the campaign settings and write down the window being used. If you sell on a marketplace rather than your own site, your tracking may be incomplete, and the platform's ROAS may understate or simply not see your sales.
Three mistakes that break the calculation
- Using gross margin instead of contribution. Leave out Etsy fees ($4.25 in the example) and your "break-even" ROAS falls to $40 ÷ $22 = 1.82x; leave out shipping ($6.00) as well and it falls to $40 ÷ $28 = 1.43x. Both are far too optimistic, and you will keep running losing campaigns.
- Comparing ROAS across different order values. A campaign for a $15 item and one for a $90 item will have different break-even points even if margins match in percentage terms, because the flat $0.25 and $0.20 Etsy fees weigh more on cheap orders. Calculate per product or per price band.
- Ignoring repeat purchases. If a first order from an ad reliably leads to a second unpaid-for order later, your true contribution per acquired customer is higher and you can tolerate a lower first-order ROAS. Only use this argument if your own order history shows the repeat rate; do not assume one.
FAQ
Is a 2x ROAS good?
Only if your break-even ROAS is below 2. In the example above, with a 44.4% contribution margin, break-even is 2.25x and a 2x campaign loses money. With a 60% margin, break-even is 1.67x and a 2x campaign is profitable.
What is the difference between ROAS and ROI?
ROAS compares revenue with ad spend. ROI compares profit with total cost. A campaign with a 2.25x ROAS in our example has a 0% ROI: it returned exactly what it cost once product, fees and shipping are counted.
Should break-even ROAS include my own labor?
Yes, if you want the ads to pay for your time as well as your materials. Put your hourly rate into "product cost" or "other costs" when you calculate contribution; it raises your break-even ROAS, but it reflects the real business.
Can break-even ROAS change over time?
Constantly. Material prices, postage rates, Etsy fee changes and discounts all move the contribution per order. Recalculate whenever one of those changes, and at least every quarter.
