FlipCalc - eBay Profit Calculator

Real-time profit calculator for eBay sellers. Know your true profit before you list.

Stop Losing Money on Hidden Fees If you've ever listed an item for $24.99 thinking you'd make good profit, only to realize you netted $1.12 after eBay fees, payment processing, and shipping... this extension is for you. FlipCalc is a real-time profit calculator that shows your TRUE net profit BEFORE you list. No spreadsheets. No calculators. No surprises. ━━━━━━━━━━━━━━━━━━━━━━ 🧮 WHAT IT CALCULATES - eBay Final Value Fee (13.25% + $0.30) - Payment Processing Fee (2.9% + $0.30) - Shipping costs (if you offer free shipping) - Your actual net profit - ROI percentage - Break-even price ━━━━━━━━━━━━━━━━━━━━━━ ✨ HOW IT WORKS 1. Install the extension 2. Go to any eBay listing or "Create Listing" page 3. FlipCalc automatically appears on the right side 4. Enter your item cost and shipping cost 5. As you type your sale price, see your real profit instantly 6. Red = losing money. Green = making money. ━━━━━━━━━━━━━━━━━━━━━━ 💡 WHO THIS IS FOR - eBay resellers who source from thrift stores, garage sales, or wholesale - Part-time flippers who need to know if an item is worth listing - Anyone tired of manually calculating fees in a spreadsheet - Sellers who've accidentally listed items at a loss ━━━━━━━━━━━━━━━━━━━━━━ 🎯 THE PROBLEM THIS SOLVES You find a jacket at Goodwill for $3. You think "I'll list this for $25 and make $22!" But after: - eBay's 13.25% cut ($3.61) - Payment processing 2.9% ($1.03) - Shipping materials ($1.50) - Your time photographing and listing (15 minutes) You actually net $16.86. Still good! But what if you priced it at $18? You'd net $9.86. What if you offered free shipping and shipping costs $5? Now you're at $11.86. FlipCalc does this math in real-time so you never list an item at a loss again. ━━━━━━━━━━━━━━━━━━━━━━ 📊 FEATURES ✓ Real-time calculation as you type ✓ Automatic fee breakdown ✓ Color-coded profit indicators (green = good, red = bad, yellow = marginal) ✓ Break-even price calculator ✓ Remembers your last shipping cost (so you don't re-enter it every time) ✓ Works on all eBay listing pages ✓ 100% privacy - no data sent to any server ✓ Zero setup required ━━━━━━━━━━━━━━━━━━━━━━ 🔒 PRIVACY FlipCalc runs entirely in your browser.
