About MarginScan - Amazon FBA Profit & VAT Calculator

Stop bleeding money on Amazon FBA fee surprises and expensive £30/month software subscriptions. MarginScan is the instant, accurate net profit & margin calculator built specifically for Amazon Online Arbitrage, Retail Arbitrage, and Wholesale sellers across the UK, US, and Europe. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚡ WHY MARGINSCAN IS DIFFERENT (NO SUBSCRIPTION FATIGUE) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Most FBA sourcing extensions charge £20 to £45 every single month—adding £240 to £500+ in annual overhead to your business before you've even made a sale. MarginScan eliminates subscription fatigue with a 7-Day Free Trial and a 1-Time Lifetime Deal (£24.99 / $29.99). One single profitable flip pays for MarginScan for life. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 KEY FEATURES BUILT FOR ARBITRAGE & WHOLESALE ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 1. TRUE NET MARGIN & CASH PROFIT Most basic calculators show "optimistic" false profits because they ignore real-world logistics costs. MarginScan calculates: • Amazon Category Referral Fees (15% standard or category-specific) • Amazon FBA Pick & Pack Fees (auto-calculated from product dimensions & weight tier) • Inbound Shipping to Amazon Warehouses (auto-calculated per kg or per lb) • Prep Center & Polybagging Costs (£0.20/unit default) • UK & EU VAT on Amazon Fees (Crucial for non-VAT registered sellers: protects you from the 20% tax Amazon charges on seller fees!) 2. MAX ALLOWABLE BUY COST (MABC) ENGINE Don't waste time guessing your buy price. Choose your target ROI (20%, 30%, 40%, 50%), and MarginScan instantly reveals the maximum price you can pay at your supplier. 3. 1-CLICK REVERSE SOURCING SHORTCUTS Find profitable inventory instantly. Jump directly from any Amazon listing to Google Shopping, eBay, Walmart, Alibaba, and Keepa price charts in one click. 4. 1-CLICK EXPORT TO GOOGLE SHEETS & CSV Build your sourcing buy-list effortlessly. Copy formatted tab-separated rows directly into Google Sheets (Ctrl+V) or export all saved leads to CSV with 1-click. 5. 📋 COMMUNITY DEAL BREAKDOWN SHARER Discussing a potential flip with your mastermind or on Reddit/Discord? Click "Copy Deal Breakdown" for a perfectly formatted markdown summary including ASIN, buy cost, fees, net profit, and ROI. 6. ZERO ACCOUNT LINKING (ZERO RISK) MarginScan runs 100% on public Amazon product pages. You NEVER need to connect your Amazon Seller Central account or share SP-API tokens, guaranteeing zero account health or suspension risks. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🌍 MULTI-CURRENCY & REGIONAL VAT ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Built for sellers operating in the UK, US, and Europe with seamless multi-currency support: • Automatic currency detection across Pounds (£), Dollars ($), and Euros (€) • Imperial and metric unit conversions (pounds/inches and kilograms/centimeters) • 1-click UK & European VAT toggles on seller fulfillment and referral fees ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY & TRANSPARENCY ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ MarginScan does not collect personal data, tracking cookies, or browsing history. All product fee math is computed locally on your device. Licensing and secure checkout are powered by Stripe via ExtensionPay. MarginScan v1.2.0 — The Amazon UK 20% Fee VAT & Sourcing Radar Update ✨ What's New in v1.2.0: • UK HMRC 20% Fee VAT Engine: 1-click toggle calculating the mandatory 20% VAT on Amazon referral and fulfillment fees for non-VAT registered UK sellers, eliminating unexpected margin loss. • Instant Sourcing Deal Verdict: Real-time decision indicator (🟢 Strong Buy / 🟡 Moderate / 🔴 Pass) with automated Buy Box and Section 3 Brand IP risk checks. • Max Allowable Buy Cost (MABC) Reverse Pills: One-click target ROI calculators (20%, 30%, 40%) that instantly calculate the maximum allowable purchase price for reverse sourcing. • Saved Sourcing Leads Vault: Filter, store, and export up to 500 profitable sourcing opportunities with clean CSV/TSV copy options. • Local Privacy-First Architecture: 100% client-side calculations with zero third-party cloud data harvesting.
