How the numbers are calculated
Revenue per unit = price. Fees: Amazon = price × referral % + FBA fee; Shopify = price × payment % + fixed fee. Profit = price − unit cost − shipping − fees − ad cost. Margin = profit ÷ price. ROI = profit ÷ (unit cost + shipping). Break-even ROAS = price ÷ (profit before ads). Your data never leaves the browser.
