- Under Ad spend (€), enter how much you spent on the campaign – the pure ad spend, without agency or production costs.
- Under Revenue from ads (€), enter the revenue the campaign demonstrably generated. Use the value from Google Ads, Meta Ads, or your store tracking.
- Enter your average profit share per order under Margin (%). All three values update the results instantly – you don’t need to submit anything.
How to read the three results
The first tile shows your ROAS, the second the Break-even ROAS, which the calculator derives from the margin you entered. The third tile works out with Profit after ad spend how many euros actually remain after cost of goods and ad spend.
Below the tiles, a colored note puts the result into context: if the note appears on a green background, your campaign is above break-even and working profitably. On a red background it is currently costing you money – the profit after ad spend is then additionally shown in red. That way you can tell at a glance whether to scale the campaign or pause it.
Practical tips for reliable ROAS values
Always calculate campaigns individually instead of using the channel average: a profitable brand campaign can mask a loss-making new-customer campaign. Also pay attention to the attribution window – if you shorten it from 28 to 7 days, the reported ad revenue usually drops significantly without anything changing in actual orders.
The most critical input is the margin: if you set it too optimistically, you get a break-even shown that reality never reaches. Work out your real margin after sourcing, shipping, and returns with our margin calculator – and then enter that figure here again.

Frequently asked questions
- How do I calculate the ROAS for my ad campaigns?
- Divide the revenue a campaign generates by the ad spend: ROAS = revenue / ad spend. With €4,000 in revenue and €1,000 in ad spend, the ROAS is 4. The calculator above handles this calculation and additionally shows you the profit after ad spend.
- What is the difference between ROAS and ROI?
- ROAS only measures the ratio of revenue to ad spend and ignores all other costs. ROI relates profit to the total capital employed, including cost of goods, shipping, and personnel costs. Anyone who only looks at ROAS often significantly overestimates their profitability.
- What is a good ROAS in e-commerce?
- That depends entirely on your margin. As a rule of thumb, a ROAS of 4 is considered solid, but with a 20% margin you need at least 5 just to cover the ad costs. What matters is your break-even ROAS, which the calculator derives automatically from your margin.
- How do I calculate my break-even ROAS?
- The break-even ROAS is 100 divided by your margin in percent. With a 40% margin that gives 2.5: every ROAS above it earns profit, every one below a loss. Note that shipping, returns, and marketplace fees lower your actual margin further and shift the threshold.
- Why am I losing money despite a high ROAS?
- A high ROAS says nothing about your cost structure. If cost of goods, shipping, return rate, and fees together eat up almost all revenue, even a ROAS of 5 is not enough. So first check your real margin after all costs, then compare the ROAS with your break-even value.
