Calculate ROAS
Enter your ad spend and the revenue that came from that ad, in your own currency. The result updates as you type.
How much you spent on this campaign in total
Revenue that came from this ad in the same period
ROAS
3.2
Doing well
1 spent brings 3.2 back. More than twice what you spent turned into revenue; if your margin is reasonable, this ad is making you money.
Revenue difference (revenue minus ad spend)
11
This is not profit, it is the revenue difference. Your product cost comes out of this.
For every 1,000 of ad spend
3,200

ROAS measures revenue, not profit. Enter your profit margin too and we calculate what the ad leaves in your pocket and the minimum ROAS you need to avoid a loss.
The share of a 100 sale that stays with you. If a product you sell for 100 costs you 60, your margin is 40.
Enter your profit margin and we will show your net profit and break-even ROAS here.
Sample calculations
Three examples to see how the formula works. We divide the revenue from the ad by the ad spend; the resulting number is ROAS.
| Situation | Ad spend | Revenue | ROAS |
|---|---|---|---|
| Cafe, weekday afternoon campaign | 3,000 | 9,000 | 3.0 (3 for every 1) |
| E-commerce, new product launch | 10,000 | 18,000 | 1.8 (on the edge) |
| Hair salon, neighborhood ad | 1,500 | 1,200 | 0.8 (loss) |
These rows are examples prepared only to show the formula, not real customer data. Enter your own numbers in the calculator above to see your result.
What does this mean?
What is ROAS?
ROAS is the ratio that shows how much revenue you earned for your ad spend. It stands for "return on ad spend". The formula is one line: divide the revenue from the ad by the ad spend.
If you spent 10,000 and made 30,000 in sales, ROAS is 3. In everyday words, for every 1 you gave to ads, 3 of revenue came into the till. If ROAS is 1 you got your money back exactly; below that, the ad did not even cover its own cost.
ROAS does not mean profit
This is the most common mistake. ROAS looks at revenue, not profit. If a product you sell for 100 costs you 60, your profit margin is 40%, and only 40 of that 100 sale is yours. In that case the ad only makes you money when ROAS is above 2.5.
That threshold is called break-even ROAS and the calculation is simple: 100 divided by the margin percentage. If your margin is 50% the break-even ROAS is 2; if it is 25%, it is 4. Asking "is a ROAS of 2 good" without knowing your own threshold is meaningless; for one business it is good, for another it is a loss. Enter your margin in the calculator above and we show you both the threshold and your net profit.
What to watch when reading ROAS
Meta counts the sales it attributes to its own ads. If a customer saw the ad and bought directly on your site two days later, Meta usually claims it. So the ROAS in the panel and the money in your bank account do not always match exactly. The right habit is to look at at least a week’s total rather than deciding on a single day’s ROAS.
For a product with a high return rate, real ROAS is lower than it looks; for a business with repeat customers, first-sale ROAS understates the real value because the same customer comes back. For businesses that collect appointments, calls or WhatsApp messages there is no instant revenue at all. There it is more accurate to look at cost per customer request instead of ROAS.
Frequently asked questions
What is a good ROAS?
There is no single number that applies to everyone, because the answer depends on your profit margin. The right question is not "what is a good ROAS" but "what is my break-even ROAS". If your margin is 40% your threshold is 2.5; a ROAS of 3 puts you in profit, 2 puts you in loss. Enter your margin in the calculator and you see your own threshold.
What is the difference between ROAS and ROI?
ROAS divides revenue by ad spend, so it only looks at the sales the ad brought. ROI takes all costs into account, such as product cost, rent and staff, and measures real profit. That is why a business can be losing money while ROAS looks high.
I don’t track sales. Can I calculate ROAS?
Approximately. Multiply the number of customers from the ad by what an average customer leaves you and you get a revenue estimate. For exact results you need to install the Meta Pixel on your site or turn on conversion tracking in the panel.
Should I switch off the ad immediately if ROAS is low?
Don’t rush. The first days of a new campaign are Meta’s learning period and the results have not settled. Wait for enough data first, then review the audience, the ad copy and your landing page. Stopping a losing campaign with a budget cap is usually smarter than switching it off completely.
Is this tool free? Do you store data?
Completely free and no sign-up. The calculation happens inside your browser; the numbers you enter are not sent to the server or stored.
You don’t have to do this calculation yourself every day
When you connect your ad account to Webdesiz, the panel tracks your ROAS, cost per customer and spend for you. Instead of a table you get sentences: how many requests came in the last 7 days, what each cost, what you need to touch today.
- The AI assistant prepares the ad copy, image and audience
- The ad is created paused; no spending starts until you approve
- Protection rules stop a campaign that exceeds its spend limit
