Know your true profit before you list
Enter purchase cost + selling price, then add platform fees, taxes, shipping, supplies, and returns.
You’ll see net profit, margin, ROI, and break-even price (including “offer” scenarios).
Inputs
Works for eBay, StockX, FB Marketplace, Amazon, Etsy, etc. (fees are configurable).
Price the buyer pays (before buyer-side tax/shipping).
Purchase price + your inbound costs (if any).
Example: eBay final value fee.
Example: PayPal/processor %.
Example: $0.30 per transaction.
Outbound label cost if you cover shipping.
Boxes, tape, inserts, etc.
Cleaning, repairs, gas, ads…
Only if *you* owe tax on the sale revenue.
Optional: apply to profit (rough estimate).
Expected return rate (affects expected profit).
If buyer offers lower — we’ll compute profit at that price too.
Multiply totals for bulk flips.
