Shopify Break Even ROAS: When Ads Stop Making Money

A campaign can show a strong ROAS and still lose money if product cost, shipping, payment fees, refunds, and discounts are high. Shopify sellers need a contribution margin model before judging ads.

Break-even ROAS tells you the minimum return on ad spend needed before profit starts.

Break-even ROAS = revenue / allowable ad spend. Allowable ad spend is the selling price minus product cost, shipping, payment fees, discounts, and other variable costs.

If a $50 product has $25 contribution before ads, the break-even ROAS is 2.0. Spending more than $25 to acquire the order loses money unless repeat purchases recover it.

Do not scale only because ROAS looks acceptable. Check cash flow, refund rate, and contribution margin by product.

If repeat purchase data is not yet proven, use first-order profit as your safety line.
