Good ROAS for Facebook Ads: Set Your Own Line From Margin

A good ROAS for Facebook ads is one at or above your target ROAS. Break-even ROAS is the line below which an order loses money; it equals 1 ÷ contribution margin. Target ROAS is break-even ROAS plus the profit you want to keep.

Turn the question around and ask what margin a ROAS needs. We calculated each row as 1 ÷ ROAS:

So a 2.3 ROAS clears break-even for a store keeping more than 43.5% of each sale and loses money for one keeping 40%. A $149 product that leaves $60 before ads breaks even at 149 ÷ 60 = 2.48.

Because a benchmark ROAS contains no margin, and margins differ widely. The annual reports of five public consumer brands imply break-even ROAS from 1.41 to 2.44 on a gross margin basis, before shipping, fees or returns, so one "good" figure sits above break-even for some brands and below it for others.

Benchmarks in published guides vary widely, so none can be matched to your margin. Our inference is that they reflect different brand mixes, date ranges and attribution windows, not different truths about Facebook.

We checked the margin side with filings. For each company we took the revenue and gross profit lines from its latest annual report (Form 10-K) filed with the U.S. Securities and Exchange Commission (SEC), divided one by the other, then divided 1 by the result:

These are break-even figures on a gross margin basis, not targets. Companies file shipping and payment costs in different places, and some of these brands also sell through stores or retailers, so a direct-to-consumer break-even will usually sit higher. Use a benchmark only to notice when your number is wildly out of line. Do not set a target from one.

Subtract every cost that rises with each order from the price, divide what is left into the price, and you have break-even ROAS. What is left per order is also your break-even cost per purchase, the most you can pay in ads for one sale without losing money.

Our worked example uses assumed costs: an $85 order, a 3% payment fee and a 6% returns allowance. Replace each with your own.

Do not use gross margin alone, and do not fold fixed overhead into the line. Variable costs set the line for an individual ad. If returns are a large share of your orders, break-even ROAS for fashion, with returns shows how that moves the number.

Ads Manager ROAS leaves out purchases outside its attribution window, orders your store records that Meta did not credit, and anything customers spend after the first order. The attribution window is the period after a click or view in which Meta credits a purchase to an ad.

Three habits keep the comparison honest:

Judge cold audiences and retargeting separately too. Retargeting reaches people who already know you, so it reports higher. One blended number can hide a weak cold-audience result.

Put each creative angle's ROAS beside its break-even line and its purchase-count range, then sort into back it, keep funding, or stop. A creative angle is the main reason to buy that an ad leads with, such as reviews, a founder story or a demo.

The range matters because few purchases make ROAS noisy. We approximate the noise as 1.96 ÷ √purchases, applied to ROAS. This is our model, it counts purchases only and ignores differences in order value, and it is a rough guide. Here are five illustrative angles on the example above (every order $85, same window, same period). They are invented to show the method, not results from any account:

The stop rules here are three. If the low end of the range is at or above break-even, back the angle. If the high end is below break-even, stop it. Otherwise keep funding, because quadrupling purchases halves the range. Sorted by raw ROAS, angle E would look ready to scale on 21 purchases. Only A and D are decided.

For ad sets, Meta recommends about 50 optimization events since the last significant edit before treating costs as stable. At 50 purchases our range is about ±28% (1.96 ÷ √50), so in our view that is where calls against a break-even line begin to settle. How the learning phase works covers the budget side, and to plan a test budget you can use our test budget calculator.

Add the profit you want to keep to your break-even ROAS to get your target ROAS; a good ROAS is one at or above it. In the $85 example, a 2.1 clears break-even at 2.06 but is not yet good; a 2.59 is.

Our recommendation is to set that target per product, review it when price, product cost or shipping changes, and treat your best angle's ROAS over the last eight weeks as your team's own benchmark.

Keep a log with one row per angle: window, spend, purchases, ROAS, range, call and the reason. A stopped angle with a reason is worth as much as a winner, because it stops the team paying to learn the same thing twice.

The line is yours to set, but deciding which angle to test next is where we work.
