Calculate return on ad spend, and the break-even ROAS your store needs to cover its cost of goods.
Revenue minus cost of goods, as a percentage of revenue — used only to calculate break-even ROAS below.
ROAS is revenue divided by ad spend. Break-even ROAS is 1 ÷ gross margin — the ROAS at which ad spend exactly consumes your gross profit on the resulting sales, before accounting for any other costs (shipping, returns, fixed overhead). This is platform-style ROAS math, not blended or true ROAS — see how to calculate true ROAS for the difference.
