What is ROAS?
ROAS (return on ad spend) measures how much revenue your advertising generates per euro spent. The formula is simple: ROAS = revenue from ads ÷ ad spend. If you spend €2,000 on Meta or Google Ads and those campaigns drive €6,000 in revenue, your ROAS is 3.0×.
The calculator above works the way campaign planning works in practice: your budget and average cost per click determine clicks, your conversion rate turns clicks into conversions, and your average order value turns conversions into revenue. Improving any one of those four numbers improves your ROAS — which is why creative and landing pages matter just as much as bid settings.
Keep in mind that a "good" ROAS is different for every business. A 4× ROAS can be highly profitable for one store and loss-making for another; it depends entirely on your margins. That is why the more important number is your break-even ROAS — the minimum return at which your ads stop losing money. Work yours out with our free break-even ROAS & max CPA calculator.
ROAS questions, answered
There is no universal good ROAS — it depends on your gross margin. As a rule of thumb, many e-commerce brands aim for 3–4× or higher, while businesses with high margins or high customer lifetime value can be profitable below that. The number that actually matters is your break-even ROAS: selling price divided by gross profit per order. Anything structurally above it is profitable.
ROAS compares ad revenue to ad spend only (revenue ÷ ad spend). ROI compares profit to total costs, including product costs, fees and agency fees. A campaign can have a positive ROAS and still a negative ROI if margins are thin — which is why we plan campaigns around break-even ROAS and maximum CPA, not revenue alone.
The four levers are the same ones in this calculator: lower your cost per click with better ad relevance and creative, raise your conversion rate with stronger creative and landing pages, raise your average order value with bundles and upsells, and cut wasted spend with sharper targeting and A/B testing. In our experience creative is the biggest lever, because it affects CPC and conversion rate at the same time.
