Break-Even ROAS Calculator
Calculate the ROAS at which ad spend exactly offsets your gross margin — a profitability threshold, not a performance score.
Gross margin as a percentage of revenue — e.g. if a $100 sale costs $60 in cost of goods sold, your margin is 40%.
At this ROAS, ad spend exactly consumes the margin it generated — zero profit, zero loss, from ad spend alone. A ROAS above this threshold is contributing profit from a margin standpoint; below it, ad spend is costing you more than the margin it returns. This assumes "margin" means gross margin (revenue minus cost of goods sold) as used above — if you define margin differently (e.g. after other variable costs), your real break-even point will differ. This is a threshold, not a guarantee of overall profitability, which also depends on costs this simple model doesn't include (overhead, returns, other operating expenses).

Break-even ROAS is the return on ad spend at which your margin exactly offsets what you spent — Break-even ROAS = 100 ÷ Gross Margin %. A 40% margin means you need at least a 2.5x ROAS just to avoid losing money on ad spend from a margin standpoint.
This assumes "margin" means gross margin (revenue minus cost of goods sold) — a different margin definition changes what break-even actually means. This is a threshold, not a guarantee of overall profitability, which also depends on costs this simple model doesn't include.
