ROAS, Break-even ROAS and Profitability: What You Need to Know
ROAS (Return on Ad Spend) shows how much revenue every 1 lira spent on ads brings back. The formula is simple: ROAS = Ad Revenue / Ad Spend. If you spend ₺10,000 and generate ₺42,000 in revenue, your ROAS is 4.2x: every ₺1 produced ₺4.2 in revenue. ACOS (Advertising Cost of Sale) is the same relationship read the other way around: spend divided by revenue. A 4x ROAS equals a 25% ACOS.
A high ROAS alone does not mean profit; your margin decides that. Break-even ROAS = 100 / profit margin. With a 30% margin your break-even point is 3.33x: every campaign below 3.33x loses money even though its ROAS looks positive. At a 20% margin the threshold rises to 5x. That is why a target ROAS should be based on your own margin, not on industry averages; remember to include shipping, commissions and returns in the margin.
ROAS also has classic pitfalls. Brand search and retargeting campaigns capture users who would have bought anyway, so they artificially inflate account-level ROAS; measuring per campaign gives a more honest picture. Second, ROAS works against scale: as budgets grow, diminishing returns push ROAS down, so the goal should be "maximum total profit above break-even", not "maximum ROAS". Third, ROAS only measures the first sale; in businesses with strong repeat purchases and high customer lifetime value (LTV), a ROAS slightly below break-even can still be profitable in the long run.
