What is a good ROAS for Google Ads?
There is no single good ROAS for Google Ads. Set it from your margin, judge it per campaign type, and feed it into Target ROAS bidding.

What a good ROAS means on Google Ads
ROAS, or return on ad spend, is revenue divided by ad spend. A 4.0x ROAS means you earn 4 in revenue for every 1 you put into ads. That number on its own does not say whether a campaign makes money, because revenue is not profit. What turns it into a verdict is your gross margin, the share of each sale left after the cost of the goods or service sold.
The general logic is the same on every channel, and the guide to what counts as a good ROAS covers it in full. What changes on Google Ads is how the platform uses the number. You do not just measure ROAS after the fact, you can hand a ROAS target to Google's Smart Bidding and let it bid toward that return automatically. So the question shifts from what is a good ROAS to what target should I feed the machine, which makes getting the figure right more consequential here than almost anywhere else.
You will see the figure 4:1 quoted as a good Google Ads starting point. Treat it as a widely cited convention that suits average retail margins, not a law. For a high-margin software business, 4x is far more than you need; for a low-margin reseller, 4x can still be a loss. The honest target is margin-first.
Margin sets your break-even ROAS
Break-even ROAS is the lowest ROAS at which a campaign stops losing money, and it depends only on your gross margin. The formula is 1 divided by your gross margin. At a 50% margin you keep 0.50 of every 1 in revenue, so you need 2 in revenue to cover 1 of ad spend, a break-even ROAS of 2.0x. Find your margin in the table and read off the line a Google Ads campaign has to beat before it makes you anything.
| Gross margin | Break-even ROAS | tROAS to enter |
|---|---|---|
| 20% | 5.00x | 500% just to break even; thin-margin resale |
| 25% | 4.00x | 400%; where the 4:1 convention comes from |
| 33% | 3.00x | 300%; typical consumer goods |
| 50% | 2.00x | 200%; healthy ecommerce and many services |
| 75% | 1.33x | 133%; software and high-margin digital |
The last column is the break-even tROAS, the floor you would enter in Google Ads as a percentage. Your actual target should sit above it so the campaign returns profit, not just covers costs. To pin down your own margin first, use the gross margin calculator, then check the exact break-even line with the break-even calculator.
A good ROAS varies by campaign type
One good number across every Google Ads campaign is misleading, because campaigns play different roles. Brand and high-intent search capture demand that already exists, so they tend to return a high ROAS. Prospecting on the Display Network or broad Performance Max (PMax) campaigns create demand and warm up cold audiences, so they usually return less. Judge each campaign against its own role and your break-even line, not a single blended figure.
| Campaign type | Role | Expected ROAS |
|---|---|---|
| Brand search | Capture people already searching your name | Highest; well above break-even |
| Non-brand high-intent search | Capture active buyers searching the category | Strong; comfortably above break-even |
| Shopping / Performance Max | Mixed intent across Google's surfaces | Moderate; near to above break-even |
| Display / prospecting | Build demand among cold audiences | Lower; often at or below break-even early |
If you hold prospecting and Display to the same ROAS as brand search, you will switch off the campaigns that fill the top of your funnel and starve the high-ROAS demand-capture campaigns downstream. The point is to set a target that fits what each campaign is there to do, then watch the blended return across all of them.
Feeding your target into Target ROAS bidding
Target ROAS (tROAS) is a Smart Bidding strategy where you set the return you want and Google's automated bidding works to hit it, raising bids on conversions it predicts are valuable and lowering them where the predicted return is poor. You enter the target as a percentage, so a 4.0x target becomes 400% tROAS. Multiply your decimal target by 100 to get the figure Google expects.
The target you feed it should come from your own numbers, not a benchmark. Start from your break-even ROAS, then add the profit you want to keep. The ROAS target calculator does that step directly: enter your gross margin and the profit margin you want to keep after ad spend, and it returns the ROAS to aim for. Convert that to a percentage and that is your tROAS. For example, a 50% margin with a 20% target profit margin gives a target of about 3.33x, which you would enter as 333%.
Set the target too high and Google bids cautiously, your impression share falls and volume dries up. Set it too low and you buy unprofitable conversions. The sweet spot is the lowest tROAS that still clears break-even with your profit cushion, because that wins the most volume while staying profitable. Then measure what each campaign actually delivers in the ROAS calculator and compare it against the target you set.
Why conversion values are the foundation
ROAS bidding is only as accurate as the conversion values you send Google. tROAS optimizes toward predicted value, so if the values flowing into your account are wrong, the bidding chases the wrong outcomes and your real ROAS drifts from the target you set. This is the most common reason a tROAS campaign looks healthy in the dashboard but loses money in the bank.
- Pass actual revenue, not a flat value. If every conversion reports the same placeholder amount, Google cannot tell a high-value order from a low one, and tROAS optimizes blind.
- Send the value that matches your margin math. If your break-even is based on revenue, the conversion value should be revenue; mixing revenue and profit across the account breaks the comparison.
- Watch for double counting and missing conversions. Duplicate tags inflate reported ROAS, missed conversions deflate it, and either one moves the bidding in the wrong direction.
Get the values right first, then set a margin-driven target. A clean conversion-value setup is what lets a good ROAS target on Google Ads actually translate into profit.
Frequently asked questions
What is a good ROAS for Google Ads?
A good return on ad spend (ROAS) on Google Ads is one that clears your break-even ROAS with room left for profit. Break-even equals 1 divided by your gross margin, so a 50% margin breaks even at 2.0x and a 25% margin needs 4.0x just to cover costs. The widely cited 4:1 starting point only fits average retail margins; the real target is set by your own margin, your growth-versus-profit goal, and the role each campaign plays.
What is Target ROAS in Google Ads?
Target ROAS (tROAS) is a Smart Bidding strategy where you set the return you want and Google's automated bidding aims to hit it. You enter it as a percentage: a 4.0x target is 400% tROAS. Google then raises or lowers bids in real time to win conversions whose predicted value matches that target. The number you feed it should be your margin-driven break-even plus the profit cushion you want, not a figure copied from someone else.
Is a 2.5 ROAS good on Google Ads?
A 2.5x ROAS means you earn 2.50 in revenue for every 1 you spend on ads. Whether that is good depends on your gross margin. At a 40% margin your break-even ROAS is 2.5x, so 2.5x is exactly break-even: it covers cost of goods and ad spend but leaves no profit. Above a 40% margin it is profitable, below it loses money.
Is a 9 ROAS good on Google Ads?
A 9x ROAS is strong for almost any margin, since break-even ROAS rarely climbs above 5x. It is common on brand and high-intent search campaigns, where you are capturing demand that already exists. A figure this high can also signal that you are underspending: if scaling the budget keeps you well above break-even, there may be profitable demand you are not yet reaching.
Is 300% ROAS good on Google Ads?
A 300% ROAS is the same as 3.0x: you earn 3 in revenue for every 1 spent. It is profitable for any business with a gross margin of about 33% or higher, which is where break-even sits. For a thin-margin reseller on a 20% margin, break-even is 5.0x, so 300% would still be a loss. Percentages and multiples describe the same thing: divide the percentage by 100 to get the multiple.
