What Is ROAS? How to Calculate Return on Ad Spend
In Brief
ROAS, or Return on Ad Spend, tells you how much revenue every 1 TL of ad budget brings back. The formula is one line: revenue from ads divided by ad spend. Spend 5,000 TL, generate 25,000 TL in sales, and your ROAS is 5:1, or 500 percent. There is no universal "good" number, because your profit margin sets the threshold. Calculate your break-even ROAS first, set the target 20 to 30 percent above it, then manage campaigns against that line.
Picture a store spending 10,000 TL a month on Google Ads. Revenue climbs in the dashboard, order count rises, the team feels good. Then the monthly books open and the cash simply is not there. The ads looked like they were working while margin quietly disappeared.
ROAS is usually the number that exposes that gap. It divides revenue attributed to ads by the money spent on those ads and reduces the whole thing to a single ratio. Simple to compute, harder to read correctly. Are you measuring gross revenue, what is your real margin, and is conversion tracking wired up properly?
What ROAS Measures
ROAS stands for Return on Ad Spend. It answers one question: how much revenue did the money I put into advertising bring back? The output is a ratio, not an amount. A campaign showing 4:1 produced 4 TL of revenue for every 1 TL spent.
Its real strength is comparability. If you judge two campaigns purely on revenue, one running on 8,000 TL and another on 1,200 TL, the bigger budget wins every time. A ratio removes that distortion because scale sits in the denominator.
Which Decisions It Drives
Three questions govern day-to-day ad management, and this metric answers all of them. Is this campaign paying for itself? Where should budget move from and move to? Is Google Ads or Meta Ads more efficient for this product? Agency reports usually lead with this column because it works at campaign level and channel level simultaneously.
Where the Formula Applies
Google Ads, Meta Ads, TikTok Ads and LinkedIn Ads all use the same math. Turkish marketplace dashboards do the same. The "ad revenue divided by ad spend" line in a Trendyol advertising report is ROAS under a different label, and Hepsiburada works identically. The channel changes, the division does not.
The Metric's Blind Spot
The ratio measures gross revenue. Cost of goods, shipping, packaging, returns, marketplace commission and payment gateway fees all sit outside it. Treating the number as a profitability signal on its own is the most expensive misreading in performance marketing. Think of it as a speedometer: it reports how fast you are moving, not whether you are pointed the right way. Direction comes from the break-even calculation. To read it alongside the other columns in your dashboard, our guide to CTR, CPC, CPM and CPA explains which indicator points to which problem.
How to Calculate ROAS: Formula and Five Examples
The calculation is almost disappointingly simple:
ROAS = Revenue From Ads / Ad Spend
Results appear either as a ratio (5:1, 3:1, 1.33:1) or a percentage (500 percent, 300 percent, 133 percent). Both express the same value. The formula is easy; deciding which revenue belongs in the numerator is where people get stuck.
Five Scenarios, Five Different Decisions
An online shoe store spent 5,000 TL on Google Ads this month and generated 25,000 TL from that traffic, giving a 5:1 ratio. A cosmetics brand running Instagram ads at 2,000 TL a week against 6,000 TL in revenue lands at 3:1. A product launch that burned 3,000 TL for 4,000 TL of sales sits at 1.33:1, and a test campaign with zero orders returns 0:1.
| Scenario | Spend | Revenue | ROAS | Decision |
|---|---|---|---|---|
| Footwear, Google Ads | 5,000 TL | 25,000 TL | 5:1 | Profitable at most margins, scale budget |
| Cosmetics, Instagram | 2,000 TL | 6,000 TL | 3:1 | Depends on margin, borderline |
| Product launch, Meta Ads | 3,000 TL | 4,000 TL | 1.33:1 | Likely a loss, optimise or cut |
| Test campaign | 1,000 TL | 0 TL | 0:1 | Pause and audit the setup |
| Remarketing | 1,500 TL | 12,000 TL | 8:1 | Shift budget here |
Converting to a Percentage
Some reporting tools display a ratio, others a percentage. Multiply by 100 to convert. A 5:1 return is 500 percent, and 2.5:1 is 250 percent. Match the units before you place two dashboards side by side, or you will judge a channel as four times better or four times worse than it really is.
Which Revenue Goes in the Numerator?
This is the step most people skip. The platform records gross order value at checkout. In an apparel store with a 15 percent return rate, that figure is fiction. Subtracting returns in the monthly report can pull a 5:1 result down to 4.25:1, which is enough to change a budget decision.
Attribution windows move the number too. The Google Ads default and Meta's seven-day click window can both claim the same purchase. Reconcile platform totals against your ecommerce order report at month end, and if the gap passes 10 percent, go back to the tracking setup.
What Counts as a Good ROAS?
"My ROAS is 3:1, is that good?" has one honest answer: it depends on your business. The same ratio is excellent for someone selling digital products and a disaster for an appliance retailer. Read the ranges below as a starting reference, never as a target handed to you.
| Sector | Common target ROAS | Why |
|---|---|---|
| Ecommerce (general) | 4:1 and above | Margins typically fall in the 20 to 30 percent band |
| B2B | 5:1 and above | Long sales cycle, high customer acquisition cost |
| Restaurants and food | 3:1 to 4:1 | Thin margins offset by repeat purchase |
| SaaS | 3:1 to 5:1 | Weak in month one, subscription revenue continues |
| Fashion and apparel | 4:1 to 6:1 | Stock risk, seasonal discounts, return rate |
Margin Sets the Threshold
Sell a product for 100 TL when it costs you 80 TL and your margin is 20 percent, which demands a high ratio. Bring the cost down to 40 TL and the margin becomes 60 percent, where even a modest return leaves profit. The rule is blunt: as margin falls, the required ratio rises.
Cost Lines That Erode Margin in Turkey
Margin here is never just cost of goods. The list worth checking:
- Marketplace commission takes a meaningful cut that varies sharply by category.
- Payment gateway fees and instalment costs bite hard on card-heavy baskets.
- Courier contract rates and free-shipping thresholds can wipe out profit on small orders.
- Return rates, especially in apparel and footwear, hit both revenue and operational cost.
A concrete case: an apparel brand running at 25 percent margin is profitable at 4:1. Launch a free-shipping promotion and the effective margin drops to 20 percent, at which point that same 4:1 is exactly break-even. Recalculate the target every time campaign conditions change.
Break-Even ROAS and Setting a Target
Break-even ROAS is the point where you neither gain nor lose. Below it you are funding sales out of profit; above it you are earning. Knowing this single number matters far more than memorising sector averages. The formula stays short: Break-Even ROAS = 1 / Profit Margin, where margin is what remains after every cost except advertising.
| Profit margin | Break-even ROAS | Typical example |
|---|---|---|
| 10 percent | 10:1 | Grocery and fast-moving goods with very thin margins |
| 20 percent | 5:1 | 100 TL sale against 80 TL total cost |
| 33 percent | 3:1 | 150 TL sale against 100 TL total cost |
| 50 percent | 2:1 | Digital products, online courses, software subscriptions |
Checking the Math
At a 20 percent margin, break-even lands on 5:1. Verify it. You spend 1,000 TL on ads and produce 5,000 TL in sales. Gross profit at 20 percent is 1,000 TL. Ad cost is also 1,000 TL. Net profit is zero. Drop below 5:1 and you start losing money on every order.
The Math of Advertising on Thin Margins
A business at 10 percent margin needs 10:1 to break even, which is out of reach in most performance categories. Three paths remain open. Keep ad budget deliberately small, raise the average order value through bundles so the margin itself improves, or bet on lifetime value and recover the first-order loss on repeat purchases.
Where to Put the Target
Once break-even is known, set your goal at least 20 to 30 percent above it. Break-even at 4:1 means a target of 5:1 or 6:1. That gap is your actual profit. Planning paid and organic traffic together makes the threshold easier to clear, since organic visitors never enter the denominator. We worked through that balance in our piece on splitting budget between SEO and ads.
ROAS or ROI? Clearing Up the Confusion
The two get swapped constantly, and the mistake is expensive. ROAS looks only at advertising spend. ROI accounts for everything: ads, product cost, operations, staff, shipping and commissions.
ROAS = Ad Revenue / Ad Spend
ROI = (Total Revenue - Total Cost) / Total Cost x 100
One Campaign, Two Verdicts
Take a real ecommerce campaign. Ad spend 5,000 TL, revenue attributed to ads 20,000 TL, cost of goods sold 12,000 TL, shipping and packaging 1,500 TL, platform commission 1,000 TL.
- ROAS = 20,000 / 5,000 = 4:1, which looks excellent in the dashboard.
- Total cost = 5,000 + 12,000 + 1,500 + 1,000 = 19,500 TL
- Net profit = 20,000 - 19,500 = 500 TL
- ROI = (500 / 19,500) x 100 = 2.5 percent
Only now does the picture become honest. The ratio reads 4:1 while the profit left over is a couple of percent of revenue. Double this campaign on the strength of ROAS alone and revenue doubles while profit does not, because every non-advertising cost scales alongside it.
How Often to Check Each
Use both on different clocks. ROAS suits daily and weekly campaign calls: which campaign is working, where should budget move? ROI belongs to monthly and quarterly business reviews: is this channel genuinely making money? Marketers watch the first, owners watch the second, and healthy teams put both numbers on the same table.
Allocating budget across channels requires reading them together. Our Google Ads versus Meta Ads budget comparison walks through which channel returns better for which product type.
Tracking ROAS in Google Ads and Meta Ads
Before you can calculate anything, you need to measure the revenue your ads produce. That depends entirely on conversion tracking. Get the setup wrong and every budget decision built on it is wrong too.
Setting Up on the Google Side
To report store sales into your Google Ads account, install the Google Tag and send the value of each order as a conversion value. A 500 TL order should land in the dashboard as 500 TL. On managed ecommerce platforms this connection is usually a single screen.
To see the metric, open the Campaigns view, go to Columns, choose Modify Columns, and under Conversions add "Conv. value" and "Conv. value / cost". The second is your ROAS. For a channel breakdown, open the ecommerce reports in Google Analytics.
Setting Up on the Meta Side
The Meta Pixel alone no longer does the job. Paired with the server-side Conversions API, browser-related data loss drops noticeably. The Purchase event and its value must fire correctly with no duplication. Inside Meta Ads Manager, customise your columns and add "Purchase ROAS" and "Website Purchase ROAS".
KVKK, IYS and Data Quality
Measurement in Turkey carries a legal layer. Firing marketing pixels without a cookie consent banner and a published KVKK privacy notice creates risk and degrades data at the same time. Visitors who decline never reach your dashboard, so the ratio reads lower than reality.
Email and SMS remarketing require registration with IYS, the national message management system. Sending to an unpermissioned list grows your penalty exposure, not your return. For stores that would rather solve pixel connections, consent handling and page speed at the infrastructure level, the Tecof ecommerce platform ships these pieces already wired.
The Target ROAS Bid Strategy
Google Ads offers an automated bid strategy called Target ROAS, and Meta reaches similar behaviour through Cost Cap. You tell the platform "I want at least 4:1 on this campaign" and the algorithm adjusts bids accordingly, using your conversion history to predict how much each user is likely to spend.
| Advantage | Drawback |
|---|---|
| Removes the manual bidding workload | Expect volatility for the first two to four weeks |
| Optimises toward the goal you define | Cannot learn without 50 to 100 conversions in 30 days |
| Prioritises higher-value customers | Sometimes turns cautious and underspends the budget |
Set a realistic goal. If break-even is 3:1, target 4:1. Enter 10:1 and the system will barely spend, leaving the campaign without enough volume to learn from.
Raising ROAS and Diagnosing a Weak One
Lifting the ratio is not a budget exercise. You either grow the numerator or spend the denominator more efficiently. The levers that grow revenue:
- Raise the average order value. Moving a free-shipping threshold from 150 TL to 200 TL pushes shoppers to add one more item. Spend stays flat while revenue climbs.
- Improve conversion rate. Landing pages should load under three seconds, checkout should be short, trust badges should be visible. Removing a single unnecessary form field can cut cart abandonment. Our conversion rate guide covers the steps in order.
- Test creative properly. Run at least three variants and sharpen the headline. "Sale on now" and "50 percent off, ends today" attract very different click quality. Our A/B testing guide shows how to structure the test.
- Build cross-sell paths. Offering a care kit to someone buying shoes grows order value on the same ad spend.
Spending the denominator well matters just as much. Open the search terms report in Google Ads weekly and push irrelevant queries into your negative list, because someone searching for "free" will not buy. If analytics shows women aged 25 to 34 averaging an 800 TL basket while men average 300 TL, shifting budget alone lifts the ratio.
A Seven-Step Diagnostic
When the ratio falls under break-even, work through these in order. The fault is usually in one place.
- Campaign breakdown: is everything weak, or is one campaign dragging the average? One at 1:1 next to one at 6:1 is common.
- Audience: which segment clicks without buying? Exclude the age or location slices that never convert.
- Creative and copy: a low click-through rate points at the ad, not the site.
- Landing page: traffic arriving with conversion under 1 percent means speed, trust or checkout needs work.
- Pricing: if a competitor is clearly cheaper, ads cannot fix it. Try a shipping or gift incentive instead of cutting price.
- Seasonality: January and February are slow in most categories while November and December peak. Compare against the same period last year.
- Competition and cost: rising CPC and CPM mean the market moved, not you. Leaning harder on remarketing makes sense in those weeks.
If you have worked all seven and the ratio still sits far below break-even, that product or that channel may simply not be right for you. Moving budget to a more profitable channel is sometimes the smartest available call.
Tomorrow morning, do one thing when you open the dashboard: sort the last 30 days of campaigns by the ROAS column, move the daily budget from the bottom campaign to the top one, and write the change down with the date. Return to that list in two weeks and you will know which lever works in your account from data rather than instinct.
Frequently Asked Questions
What is the difference between ROAS and ROI?
ROAS compares only ad spend against revenue from ads. ROI includes every cost, from product and shipping to commission and operations. That is why a campaign can show 4:1 while returning 2 percent ROI. Use the first for campaign decisions and the second for business decisions.
What is a good ROAS?
There is no single correct figure. Ecommerce commonly references 4:1, but the answer tracks your profit margin. A digital product at 50 percent margin profits at 2:1, while a business at 10 percent margin only breaks even at 10:1. The right answer is your own break-even number.
How do I convert ROAS to a percentage?
Multiply the ratio by 100. A 4:1 return is 400 percent and 2.5:1 is 250 percent. Some dashboards show ratios and others show percentages, so match the units before comparing reports. Otherwise you can misread performance by a factor of four.
Should I pause a campaign as soon as ROAS drops?
No, let enough data accumulate first. New campaigns spend their first 7 to 14 days in a learning phase where volatility is expected. Pause campaigns that sit clearly below break-even and have not recovered in two weeks. For the rest, try creative and audience changes before cutting.
Why is remarketing ROAS always higher?
That audience already knows your brand and has shown purchase intent once. Showing a small incentive to someone who viewed a product without adding it to the basket converts well. In most accounts this segment runs at two to three times the return of cold traffic.
Does the calculation work the same on marketplaces?
The formula does not change: ad revenue divided by ad spend. On channels like Trendyol and Hepsiburada, though, commission cuts the margin significantly, so your break-even sits higher than it does on your own site. Managing both against a single target will mislead you.
What happens if conversion tracking is broken?
The ratio reads lower than reality and you end up pausing campaigns that were actually working. Missing pixels, double counting and conversion values sent as zero are the three most common faults. Place a test order once a month to confirm the correct amount reaches the dashboard, and add server-side measurement where you can.
Should returns be subtracted from the calculation?
In monthly reporting, yes. Platforms record gross value before returns. In a category running a 15 percent return rate, that difference is large enough to change a budget decision. Use the dashboard figure for daily campaign monitoring and the returns-adjusted figure for month-end review.
Why does combined platform ROAS exceed my actual revenue?
Both platforms can claim the same sale inside their own attribution window. If a shopper sees an Instagram ad and later searches your brand on Google, the order appears in both dashboards. Compare campaigns within a platform, and take total revenue from your ecommerce order report instead.
How often should I update my target?
Whenever your cost structure moves. A change in supplier pricing, courier rates or commission shifts your margin, which shifts break-even with it. Make recalculating the target part of every price list update. Stores that review it twice a year are usually working from a stale threshold.
