Every advertiser wants one clear answer: is this campaign making money? Your ROAS is the first place to look. This free ROAS calculator turns your revenue and ad spend into your return on ad spend in seconds. It also shows your true ROAS with fees, your cost per purchase, and an estimated profit once you add your product costs.
ROAS means return on ad spend. To calculate it, divide your campaign revenue by your ad spend. For example, 3,000 in revenue from 1,000 in ad spend gives a ROAS of 3, or 3x. That means you earned 3 for every 1 you spent on ads. But remember, ROAS is not profit. Enter your own numbers below to see your ROAS, your true ROAS with fees, and your estimated profit.
Enter your ad spend and campaign revenue to get your ROAS. Add purchases, product costs, and fees to see your true ROAS and estimated profit too. Pick your currency and platform first, then use the same currency in every money field. The calculator does not convert exchange rates.
Results are estimates based only on the numbers you enter. ROAS measures revenue against ad spend, and it does not equal profit. Real results depend on product margin, cost of goods, shipping, refunds, payment fees, creative, tracking, landing page, and setup. This is not financial or advertising advice.
A ROAS calculator measures your return on ad spend. It shows how much revenue your ads earned for each unit of currency you spent.
The math is simple. You divide your campaign revenue by your ad spend. A ROAS of 3 means you earned 3 in revenue for every 1 in ad spend.
This tool does more than the basic sum, though. It also shows your true ROAS once fees are added. And when you enter your product costs, it estimates your profit too.
That extra step matters. A strong ROAS can still hide a loss if your margins are thin. So this calculator helps you see revenue and profit side by side.
One honest note comes first. This is a planning tool. It measures what your campaign did. It cannot promise what the next one will do.
Follow these simple steps.
First, pick your currency and campaign platform. The currency selector only changes the symbol. The platform changes the wording of your result.
Next, enter your ad spend and campaign revenue. These two fields are all you need for a basic ROAS.
Then add optional numbers for more detail. Add purchases for cost per purchase and average order value. Add clicks for your conversion rate.
After that, add your product costs to unlock profit. Enter product cost, shipping, payment fee, and returns. The tool then estimates your profit after ad spend.
Finally, add any fees and press Calculate ROAS. Then read the plain English explanation under the results.
Here is exactly what the calculator does. It is written in plain words.
Notice one key point. ROAS uses revenue, not profit. That is why the profit fields matter so much.
Imagine an online store running a sales campaign. Here are the numbers.
First, the basic ROAS. Revenue of 3,000 divided by 1,000 spend gives a ROAS of 3, or 3x.
Now the profit view. The average order value is 50. Product cost, shipping, and fees come to about 23.45 per order. So profit before ads is about 26.55 per order.
Across 60 orders, gross profit before ad spend is about 1,593. Take away the 1,000 ad spend. Your profit after ad spend is about 593.
So a 3x ROAS was profitable here. But the profit is far smaller than the revenue. That gap is the whole point.
Now picture a Google Ads campaign for the same store. Here are the numbers.
The ROAS is 2,000 divided by 800, which is 2.5x. The cost per purchase is 800 divided by 40, which is 20. The conversion rate is 40 divided by 1,000, which is 4 percent.
Is a 2.5x ROAS good? It depends on your margins. Add your product costs to find out. Our break even ROAS calculator shows the minimum ROAS your margins need.
Now a Meta Ads campaign on Facebook and Instagram. Here are the numbers.
The basic ROAS is 1,500 divided by 500, which is 3x. But add the 150 management fee. Your total campaign cost is 650. So your true ROAS is 1,500 divided by 650, which is about 2.31x.
That drop matters. The platform shows 3x, but your real return is lower. This is why fees belong in every honest ROAS review.
ROAS and profit are not the same. This is the most common ROAS mistake.
ROAS compares revenue to ad spend. It ignores your product cost, shipping, and fees. So a high ROAS can still mean a low profit, or even a loss.
Think of two stores with the same 3x ROAS. One sells items with fat margins. The other sells items with thin margins. The first keeps real profit. The second may barely break even.
So never judge a campaign on ROAS alone. Always compare it with your profit margin. A high ROAS does not always mean profit. And a low ROAS does not always mean failure.
Your platform ROAS uses ad spend only. Your true ROAS adds the fees you pay to run the ads.
Those fees include management, setup, and other costs like tools or creative. Add them to your spend, then divide revenue by that larger number.
On small budgets, this gap can be large. A fixed management fee can pull a healthy looking ROAS down sharply. So use the platform ROAS to compare campaigns. Then use the true ROAS for real decisions.
Every ROAS depends on accurate numbers. If your revenue tracking is wrong, your ROAS is wrong too.
Ad platforms count conversions based on their own attribution windows. Those numbers can differ from your real sales. So compare platform data with your store or CRM data.
Set up conversion tracking before you trust any ROAS. Our guide on how to set up PPC conversion tracking walks through it. For online stores, our guide on how to set up Meta Ads for ecommerce covers the tracking too.
Then give a campaign enough time and sales to form a real sample. A few conversions prove very little.
It is a tool that measures your return on ad spend. It divides your campaign revenue by your ad spend. This one also shows true ROAS with fees, cost per purchase, and an estimated profit when you add your costs.
Divide your campaign revenue by your ad spend. For example, 3,000 revenue from 1,000 spend gives a ROAS of 3, or 3x. You can show it as a number or a percentage. A 3x ROAS is the same as 300 percent.
Return on ad spend is the revenue you earn for each unit spent on ads. It measures how efficiently your ads turn spend into revenue. It does not measure profit on its own.
There is no universal good number. It depends on your product margins. A store with fat margins can profit at a low ROAS. A store with thin margins may need a much higher one. Compare your ROAS with your break even ROAS.
No. ROAS compares revenue to ad spend only. Profit is what remains after all your costs. A campaign can show a strong ROAS and still make little profit if margins are thin.
Because ROAS ignores your costs. Product cost, shipping, fees, and returns all reduce profit. A 3x ROAS on a low margin product can leave very little behind. That is why this tool also estimates profit.
Yes. Enter your Google Ads spend and the revenue it produced. Pick Google Ads as the platform. The math works the same for Search, Shopping, and other campaign types.
Yes. Use your Meta Ads spend and revenue from Facebook or Instagram. Pick the right platform in the dropdown. Just make sure your revenue figure matches the same campaign and period.
Yes. It suits Shopify, WooCommerce, and other stores well. Add your product cost, shipping, fees, and returns. Then you see your true ROAS and estimated profit, not just revenue.
For a fair platform comparison, keep them out. For a real business view, add them. This tool shows both. The true ROAS output includes your management, setup, and other fees.
True ROAS adds your fees to your ad spend, then divides revenue by that total. It shows what your ads really returned after the cost of running them. It is usually lower than the platform ROAS.
Review it regularly once a campaign runs. Also check it after any big change to ads, targeting, or budget. Watch the trend over time, and always read it next to your profit.
ROAS is the fastest way to see if your ads earn their keep. But it is only the start of the story. Revenue is not profit, and the platform number is not your true return.
So use this calculator for the full picture. See your ROAS, your true ROAS with fees, and your estimated profit. Then judge your campaign against your margins, not against a benchmark someone else set.
