ROAS questions
There's no universal number. A good ROAS is any ROAS above your break-even ROAS, which depends on your profit margin. At a 30% margin you break even at roughly 3.33×, so anything above that is profit. A thin-margin retailer needs a much higher ROAS to stay profitable, while high-margin software can be healthy at 2×. Always compare your actual ROAS to your own break-even, not to a generic benchmark.
ROAS is revenue divided by ad spend, shown as a multiple like 4×, so it ignores margin and counts top-line return. ROI is profit relative to spend, shown as a percentage, so it reflects what you actually keep. A campaign can show a strong ROAS yet a thin or negative ROI once cost of goods and margin are factored in. That's why this calculator reports both.
Break-even ROAS is 1 divided by your profit margin expressed as a decimal. At a 25% margin that's 1 ÷ 0.25 = 4×, meaning every dollar of ad spend must return four dollars of revenue just to cover costs. Beat that number and you're profitable; fall below it and you're losing money on every sale, even if the campaign looks busy.
