Calculate ROI for e-commerce investments: ad spend, platform fees, inventory costs. Get net profit, gross margin, and return on ad spend (ROAS).
> Calculate your ad ROI. Use sliders to model scenarios.
For e-commerce businesses, ROI calculations need to account for multiple cost layers: product cost (COGS), advertising spend (Google, Meta, TikTok), platform fees (Shopify, Amazon), shipping, and returns. The key metrics to track: ROI on total investment, ROAS (Return on Ad Spend = Revenue / Ad Cost), and Profit Margin ((Revenue − COGS) / Revenue × 100%). A healthy e-commerce operation typically targets ROAS of 3-5x (300-500%) and net margin of 10-20%.
ROAS (Return on Ad Spend) = Revenue / Ad Spend — it measures the revenue generated per dollar of advertising only. ROI includes ALL costs (ads, platform, shipping, COGS). ROAS of 4x = $4 revenue per $1 ads. This doesn't account for product cost, so a 4x ROAS can still be unprofitable if margins are thin.
