What is ROAS?
ROAS (return on ad spend) is the metric that shows how much revenue you generated for every euro of ad spend. We use it to judge the performance of individual ads, campaigns and channels directly. You calculate it by dividing the revenue attributed to ad campaigns by total ad spend.
How do we calculate ROAS?
We write ROAS as a ratio (4 : 1), a multiple (4x) or a percentage (400 %).
Formula
Example
You spent 5.000 € on a Google campaign. The campaign generated 25.000 € in revenue.
For every euro spent you generated 5 € in revenue. The result is a ratio with no unit; we write it as 5 : 1 or 5x.
Why does ROAS matter?
We judge campaign performance by ROAS first. Keep in mind that ROAS measures revenue, not profit.
A high ROAS does not necessarily mean a profitable campaign. It only means the ads generated revenue relative to spend. If the cost of goods, logistics and team is high, a campaign with a 3x ROAS can still run at a loss.
ROAS tells you which campaigns work and which are worth scaling. If you want to know whether the business actually earns money, you need ROI.
ROAS vs. ROI
| ROAS | ROI | |
|---|---|---|
| What it measures | Revenue relative to ad spend | Profit relative to total investment |
| Formula | Revenue ÷ ad cost | (net profit ÷ total investment) × 100 |
| Takes into account | Ad cost only | All costs (production, team, tools …) |
| Best for | Judging individual campaigns | Judging overall profitability |
Example
A campaign has a 5x ROAS. Sounds great, but once you add the cost of production, logistics and team, ROI is negative. ROAS looks only at the ratio between ad spend and the revenue from those ads, ignoring the rest of the business costs.
What is a good ROAS?
There is no universal answer. A good ROAS depends on your margin, industry and business model. A useful approach is to calculate what ROAS your business needs to cover its costs.
Formula
Examples
Gross margin
Break-even ROAS
A company with a 20 % margin needs a ROAS of at least 5x for advertising to even cover the cost of goods.
Indicative benchmarks
Values vary by industry, product and season. The figures below are indicative.
eCommerce · general
Medians for Shopify stores range from 2,5x to 3,8x depending on the source. The average eCommerce ROAS fell to 2,87x in 2025, 4 % lower than a year earlier, mostly because of rising CPM.
By channel
| Channel | Indicative ROAS |
|---|---|
| Google Search | 2x–4x (depends on intent and competition) |
| Meta Ads | 2,5x–3x (after the 2025–2026 CPM rise) |
| LinkedIn Ads | 1,5x–2,5x (high CPC, but quality B2B leads) |
| TikTok Ads | 2x–2,5x (less mature conversion infrastructure) |
All of the above are global averages. For CEE the ranges differ, because the market, competition and CPM are different. We publish real regional ranges every quarter in the State of CEE Growth Report.
Why ROAS falls
In 2025–2026, falling ROAS is the common experience of most advertisers. Meta has recorded CPM growth of 20 % and more. Google Ads is getting more expensive as new advertisers enter the auctions. A fall in ROAS typically has three causes.
More expensive advertising. Platforms charge more for the same reach. Conversion has not changed, but the cost has.
Creative fatigue. The same ads with the same message lose effectiveness over time. CTR falls, CPM rises, and ROAS follows.
An attribution problem. Changes in tracking (iOS, a badly set up pixel) mean ads generate sales the system does not detect. ROAS in the report looks low, while actual revenue is higher.
Before you change strategy, find out which of these three causes applies to you.
The three most common myths about ROAS
A higher ROAS is always better. A campaign with an 8x ROAS on a small budget and one with a 3x ROAS on a budget ten times larger are not worth the same. ROAS in isolation, without scale and margin, does not tell you enough.
ROAS can be compared across industries. Fashion has a structurally different ROAS than software. A seasonal product has a different ROAS than one that is not tied to time. Comparisons make sense within the same category and model.
Raising the budget raises ROAS. More often the opposite. With a bigger budget, ads reach a less relevant audience and ROAS falls. Before scaling the budget, stabilise ROAS at a smaller scale.
ROAS is not the goal. LTV:CAC is.
Just as important: do not focus only on ROAS and neglect the LTV:CAC ratio.
ROAS measures campaign revenue. For sustainable growth, the more relevant measure is the ratio between customer lifetime value (LTV) and acquisition cost (CAC). A customer who buys once at a high ROAS is worth less than a customer who comes back.
How to improve ROAS
Ad performance is usually improved in three places, not necessarily all at once.
Creative and segmentation. An ad that speaks to the right person with the right message converts better at the same CPM. A regular cycle of testing formats and messages is the single most important factor.
Landing page. Traffic that arrives on a low-converting page loses money. Raising the conversion rate by 1 % at the same traffic lifts ROAS without any change in ad spend.
Attribution and measurement. ROAS cannot be better than the measurement behind it. A correctly set up Meta Pixel, CAPI for offline conversions and aligned attribution models are a prerequisite, not an upgrade.
FAQ
What ROAS do I need for profitable advertising?
It depends on your gross margin. Calculate your break-even ROAS: divide 1 by the gross margin. With a 30 % margin, break-even ROAS is 3x. Below that, advertising does not cover the cost of goods.
Is a 2x ROAS good?
With a margin above 50 %, yes. At exactly 50 % you break even. At a 20 % margin, no. Without the margin as context, that number is worthless.
What is the difference between ROAS and ROI?
ROAS measures revenue relative to ad cost. ROI measures profit relative to the total investment, including all costs. A campaign can have a high ROAS and a negative ROI at the same time.
Why is my ROAS falling when I have not changed anything?
Most often because of rising CPM. Platforms charge more for the same reach while conversions stay the same. The second cause is creative fatigue: the same ads lose effectiveness over time. The third is attribution: because of changes in tracking (iOS, a badly set up pixel), the system misses part of the sales. Before you change strategy, check which of these three applies to you.
How do I improve ROAS?
The three most common fixes: better audience segmentation, landing page optimisation (higher conversion at the same traffic) and a regular cycle of creative testing. Raising the budget without these steps typically does not improve ROAS.
