The Break-even ROAS Planner needs three inputs: your gross margin percentage, average order value (AOV), and your website or funnel conversion rate. From those three numbers alone it derives your break-even cost-per-sale, break-even cost-per-click and break-even ROAS — the point where paid media spend and revenue cancel out.
Because it runs entirely in your browser, you can test different margin or AOV scenarios in seconds — useful before a promotion or price change, when your break-even point moves and your media buying needs to move with it.
