Short answer: a good ROAS for Google Ads is any return that sits comfortably above your own break-even ROAS. For most e-commerce brands that lands between 3x and 5x, for lead generation between 2x and 4x on tracked pipeline value, and for local service businesses between 4x and 10x on booked job value. The averages you find online are useful as sanity checks, but they will never tell you whether your account is profitable.
This guide breaks down the math, gives you realistic benchmark tables, and shows exactly why a 4x ROAS can still lose money.
What ROAS actually means (and how to calculate it)
ROAS stands for Return On Ad Spend. It answers one question: for every euro or dollar you put into Google Ads, how much revenue came back?
ROAS = Conversion value / Ad spend
Example: you spend $2,000 on Google Ads and generate $8,000 in tracked revenue.
- 8,000 / 2,000 = 4
- Expressed as a ratio: 4:1
- Expressed as a percentage: 400%
Google Ads reports this in the Conv. value / cost column. Google Analytics 4 reports it under Advertising or in the Google Ads integration. The two will rarely match perfectly because of attribution windows and modelling, which is a problem we come back to later.
ROAS vs ROI vs CPA: do not mix them up
| Metric | Formula | What it tells you |
|---|---|---|
| ROAS | Revenue / Ad spend | Media efficiency only. Ignores product cost and overhead. |
| ROI | (Profit – Total cost) / Total cost | Whether the business actually made money. |
| CPA | Ad spend / Conversions | Cost per order or per lead. Better for lead gen with fixed deal values. |
| POAS | Gross profit / Ad spend | The honest version of ROAS. Target above 1. |
The only benchmark that really matters: your break-even ROAS
Before you chase an industry average, calculate the point where Google Ads stops costing you money.
Break-even ROAS = 1 / Gross margin
If your gross margin is 30%, your break-even ROAS is 1 / 0.30 = 3.33x. Below that number, every additional sale makes your bank balance smaller.
| Gross margin | Break-even ROAS | Healthy target (profit + overhead) |
|---|---|---|
| 15% | 6.67x | 9x or higher |
| 20% | 5.00x | 7x |
| 25% | 4.00x | 5.5x |
| 30% | 3.33x | 4.5x |
| 40% | 2.50x | 3.5x |
| 50% | 2.00x | 2.8x |
| 60% | 1.67x | 2.3x |
| 70% | 1.43x | 2x |
| 80% (software, digital) | 1.25x | 1.8x |
The “healthy target” column adds roughly 35% on top of break-even to cover fixed costs, returns, payment fees and a real profit margin. That buffer is where most small businesses get caught out.
Why a 4x ROAS can still lose money
Here is a worked example that we see constantly in audits. An online store sells a $100 product and reports a 4x ROAS. On paper that looks excellent.
| Line item | Per order |
|---|---|
| Revenue (average order value) | $100.00 |
| Cost of goods (72% of price) | -$72.00 |
| Shipping and packaging | -$6.00 |
| Payment processing (2.5%) | -$2.50 |
| Returns and refunds (5% blended) | -$5.00 |
| Ad spend at 4x ROAS | -$25.00 |
| Result | -$10.50 per order |
This account needs a 6.7x ROAS just to break even, and the owner is celebrating 4x while quietly funding every sale. Meanwhile a software business with 85% margins can be very profitable at 1.8x.
Takeaway: “good” is not a number you copy from a blog post. It is a number you calculate from your own P&L. Industry averages only tell you whether you are roughly in the right neighbourhood.
Good ROAS benchmarks by industry
With that caveat in place, here are realistic directional ranges for Google Ads accounts in 2026. These assume solid conversion tracking and a blended view across Search, Shopping and Performance Max.
| Industry | Typical gross margin | Typical ROAS range | Strong performance |
|---|---|---|---|
| Fashion and apparel | 50-65% | 2.5x – 4x | 5x+ |
| Beauty and cosmetics | 60-75% | 2.5x – 4.5x | 6x+ |
| Consumer electronics | 12-25% | 6x – 10x | 12x+ |
| Home and furniture | 35-50% | 3x – 5x | 6x+ |
| Food, drink and supplements | 40-60% | 2x – 4x (subscription model) | 5x+ |
| Jewellery and luxury | 50-70% | 3x – 6x | 8x+ |
| B2B services and SaaS | 70-90% | 2x – 4x on pipeline | 5x+ |
| Legal and financial services | Very high | 3x – 8x on closed value | 10x+ |
| Home services (plumbing, HVAC, roofing) | 40-60% | 4x – 8x | 10x+ |
| Healthcare and dental clinics | High | 5x – 12x on patient value | 15x+ |
| Travel and hospitality | 15-30% | 5x – 9x | 12x+ |
| Digital products and courses | 85-95% | 1.8x – 3x | 4x+ |
Notice the pattern: low-margin categories need high ROAS, high-margin categories can live happily at 2x. Comparing an electronics retailer to a course creator is meaningless.
Good ROAS targets by business model
1. E-commerce
E-commerce is the easiest case because revenue is tracked natively. Set your target like this:
- Calculate contribution margin after COGS, shipping, fees and returns.
- Divide 1 by that margin to get break-even ROAS.
- Add 25 to 40% for overhead and profit.
- Decide whether you are optimising for first order ROAS or lifetime value ROAS. If 40% of customers reorder within 12 months, you can accept a lower first-order number.
Expect branded search campaigns to report 8x to 20x and cold Shopping or Performance Max traffic to report 1.5x to 3.5x. A single blended account ROAS hides both. kiezogrowth.com makes the same point with more data.
2. Lead generation
There is no revenue at the point of conversion, so ROAS only works if you assign realistic values to each conversion action. Use this formula:
Lead value = Average deal value x Gross margin x Lead-to-close rate
Example: a $4,000 average project, 45% margin, 20% of leads close. For the wider picture, see What Is a Good ROAS in 2026.
- 4,000 x 0.45 x 0.20 = $360 per lead
- If you can acquire a lead for $90, your ROAS on profit is 4x
- Your maximum cost per lead before break-even is $360
Assign different values to different actions: a demo request is worth more than a newsletter signup, and a phone call over 60 seconds is worth more than a form fill from a generic contact page. Then let Smart Bidding optimise toward value rather than raw volume.
3. Local service businesses
Local accounts usually run small budgets with high intent, so the ROAS ceiling is high but the data volume is low. Targets of 5x to 10x on booked job value are realistic for plumbers, electricians, dentists and law firms, because click costs are offset by large ticket sizes.
Three things matter more than bidding here:
- Call tracking, since 50 to 70% of local conversions happen by phone
- Tight geo-targeting with location exclusions for areas you will not travel to
- Ad schedule alignment with the hours someone actually answers the phone
How budget size changes what “good” looks like
Smart Bidding needs data. An account with 8 conversions a month cannot support the same strategies as one with 800. Here is a realistic guide to what to expect at different spend levels.
| Monthly budget | Recommended bid strategy | Realistic ROAS expectation | Main constraint |
|---|---|---|---|
| Under $500 | Manual CPC or Maximise Clicks with CPC cap | Highly volatile, judge over 90 days | Not enough data for algorithms |
| $500 – $2,000 | Maximise Conversions, then Max Conv. Value | Break-even to 3x while learning | Keyword coverage and landing page quality |
| $2,000 – $10,000 | Target ROAS once you hit 30+ conversions/month | 3x – 5x e-commerce, 4x – 8x services | Creative, feed quality, segmentation |
| $10,000 – $50,000 | tROAS with campaign-level targets | Stable 3x – 6x, tunable by campaign | Incrementality and market size |
| $50,000+ | tROAS plus profit-based values (POAS) | Deliberately lower ROAS to grow volume | Diminishing returns curve |
An important nuance: ROAS and growth pull in opposite directions. You can almost always raise ROAS by cutting spend down to branded and bottom-funnel keywords, but total profit falls. The right question is not “how high can my ROAS go” but “what is the lowest ROAS I can accept while still growing profit”.
The levers that actually move ROAS
ROAS can be rewritten as a chain of four variables:
ROAS = (Click-through rate x Conversion rate x Average order value) / Cost per click
That means there are exactly four places to pull. Most advertisers only ever touch bidding, which is usually the weakest lever.
Lever 1: Landing page conversion rate (biggest impact)
Moving conversion rate from 1.5% to 2.5% raises ROAS by 67% with zero change to spend. Typical wins:
- Match the headline to the exact search query, not to your brand slogan
- Cut page load time below 2.5 seconds on mobile
- Put the price, delivery time and return policy above the fold
- Reduce form fields to the minimum (each extra field costs conversions)
- Add trust signals: reviews, guarantees, real photos, phone number
- Send each ad group to a dedicated page rather than the homepage
Lever 2: Average order value
Raising AOV lifts ROAS proportionally and instantly.
- Free shipping thresholds set slightly above current AOV
- Bundles and multi-packs featured in Shopping feed titles
- Post-add-to-cart upsells and quantity discounts
- Subscription options for consumables
- Bid more aggressively on high-AOV product categories
Lever 3: Bid strategy and targets
- Do not switch to Target ROAS until you have at least 30 conversions in 30 days, ideally 50
- Set your first tROAS at your trailing 30-day actual, not at your dream number
- Adjust in increments of 10 to 15%, then wait 2 weeks for the learning period
- Setting a target too high is the single most common way to strangle a campaign: impressions collapse and you lose volume without gaining profit
- Split branded and non-branded into separate campaigns so branded ROAS does not mask weak prospecting
Lever 4: Cost per click and waste
- Review the search terms report weekly and add negatives aggressively
- Exclude “free”, “cheap”, “jobs”, “DIY” and competitor misfires where relevant
- Improve Quality Score through ad relevance and page experience to reduce CPC
- Use exclusions for low-value audiences and existing customers in prospecting campaigns
- Trim Display Network expansion if it is quietly eating 30% of budget inside Performance Max
Red flags that your reported ROAS is lying to you
Before optimising, make sure the number is real. Check for all of these:
- Double counting: both Google Ads tag and GA4 import firing for the same purchase
- Counting every conversion: sales, newsletter signups and PDF downloads all stacked into one “Conversions” column
- Revenue includes tax and shipping: inflates ROAS by 10 to 25%
- Refunds never deducted: especially damaging in fashion where returns can top 30%
- Branded search credited with organic demand: people who were coming anyway
- Long attribution windows: a 90-day window makes last month look far better than it was
- Performance Max absorbing branded traffic: use brand exclusions to see true incremental performance
A useful cross-check: compare Google Ads reported revenue with the revenue in your store back office for the same period. If the gap is over 20%, fix tracking before you touch bids.
A practical 30-day plan to raise ROAS
- Week 1: Calculate true contribution margin and break-even ROAS. Audit conversion tracking and deduplicate conversion actions.
- Week 2: Split branded and non-branded. Add brand exclusions to Performance Max. Clean the search terms report and add negatives.
- Week 3: Improve the two landing pages receiving the most spend. Fix speed, headline match and form length. Add a free shipping threshold or bundle to lift AOV.
- Week 4: Set Target ROAS at your trailing 30-day result, feed profit-based conversion values where possible, and pause anything that has spent 3x your target CPA without converting.
Then repeat. ROAS improvement is compounding maintenance, not a one-off fix.
FAQ
How do I calculate ROAS in Google Ads?
Divide total conversion value by total ad spend. In the Google Ads interface, add the Conv. value / cost column and it calculates automatically for any date range, campaign or ad group.
What ROAS should I aim for?
Aim for your break-even ROAS (1 divided by your gross margin) plus roughly 30 to 40% to cover overhead and profit. For a 40% margin business, that means targeting around 3.5x rather than the generic 4x you read online.
Is 2x ROAS good?
It is excellent for a digital product with 90% margins and disastrous for an electronics retailer with 18% margins. Margin decides, not the number.
Is $1 a day good for Google Ads?
No. At $1 a day you will collect around 30 to 60 clicks a month in most niches, which is far too little data for Smart Bidding to learn and too little volume to judge ROAS. For a meaningful test, plan for a minimum budget that can generate 30 conversions per month at your expected cost per conversion.
What is a good conversion rate for Google Ads?
Across Search, 3 to 6% is typical, with e-commerce often sitting at 1.5 to 3% and lead generation and local services reaching 8 to 15% on well-built landing pages. High-intent branded searches can exceed 20%.
Why did my ROAS drop after switching to Target ROAS?
Usually because the target was set too high, which restricts the auctions the campaign enters, or because the campaign re-entered a learning period. Give it 14 days, then adjust by no more than 10 to 15% at a time. Originally covered on https://choco-up.com.
Should I use ROAS or POAS?
If your products have very different margins, use POAS (profit on ad spend) by sending profit values rather than revenue values into Google Ads. It stops the algorithm from chasing high-revenue, low-margin products.
The bottom line
A good ROAS for Google Ads is not 4x. It is the number that sits above your break-even threshold with enough room for overhead and profit, measured with tracking you actually trust. Start from your margin, validate your data, then pull the conversion rate and AOV levers before you touch bidding.
