No black box. Here's the math.
Flippt tells you how to spend money — so you deserve to see exactly how every verdict is computed.
Real eBay market data, every scan
When you analyze an item, Flippt queries eBay's official APIs in real time for comparable listings — up to 40 of them — and computes the median, the typical range, and the full spread. Nothing is made up, cached for days, or "estimated by AI."
Today, prices are derived from current listings and calibrated down 13%, because items rarely sell at asking price — you'll see an "EST. SOLD VALUES" label on every result. We've applied for eBay's exact sold-price data program; the moment it's granted, verdicts switch to true sold prices automatically and the label disappears.
What "you make" actually means
− ebay fees 13.25% + $0.30 per order
− shipping your size estimate, if you ship free
− your cost what they're asking for it
= net profit the number on the verdict
ROI is net profit divided by your cost. A $10 buy that nets $15 is a 150% return — better than most things you can legally do with ten dollars.
Where the line is drawn
Net profit of at least $15 AND at least 50% ROI. Worth your trunk space and your time at the post office.
Profitable, but thin — or fewer than 5 comparable listings, which means low confidence. Buy it only if you know the niche.
You'd lose money at the typical sale price. Put it down and feel nothing.
It stays on your device
Your scan history, watchlist, and profit ledger live in your browser's local storage — we don't have accounts, and we can't see them. Photos are processed in memory to identify the item and detect condition flaws, then discarded; they are never stored or used for anything else.
