Professional local profit and margin calculator with auto-grab features for e-commerce sellers.

$9.99 One-Time Purchase — Lifetime Access (No Subscriptions) E-Com Margin & Profit Pro is a high-performance, privacy-first browser utility designed to give e-commerce entrepreneurs, dropshippers, and multi-channel merchants instantaneous visibility into their true bottom line. By stripping away complex, bloated server-side software, this tool runs entirely local to the user's browser, providing lightning-fast financial modeling with zero data leakage. Key Capabilities One-Click Price Auto-Grab: Instantly pull product pricing straight from active Etsy and eBay pages directly into your calculator with a single click, eliminating tedious manual typing. Granular Cost Breakdown Engine: Instantly calculates gross margins, net profit, and profit percentages by factoring in multifaceted expenses beyond simple Cost of Goods Sold (COGS)—including payment gateway transaction fees, warehousing costs, regional shipping tiers, and marketing ad spend. Local Session Storage Manager: Allows users to save, catalog, and compare multiple product variations and pricing strategies directly in their browser storage without requiring external databases or cloud logins. "What-If" Margin Simulator: Empowers sellers to stress-test their pricing strategies against fluctuating supplier costs or discount thresholds before committing to store-wide promotions. 100% Air-Gapped Privacy: Because it operates entirely client-side via lightweight HTML, CSS, and vanilla JavaScript, sensitive product data, proprietary margins, and pricing formulas never leave the user's machine.
