The flip intelligence Card Ladder never built.

Grade ROI Engine

Should you even grade it? Real 2026 fees + turnaround, weighed against your grade odds.

Odds are yours to set — be honest. A card that grades PSA 9 instead of 10 is where money dies. Assumes ~13.6% sell fee on the graded sale.

Net-in-Hand by Venue

You lose 28–35% to fees. Here's your real take-home on each platform, ranked.

eBay 13.6%+$0.40 · StockX ~9%+3% · Whatnot ~8% · Consignment ~18% (but usually a higher sale) · Reddit/local 0% (slower, cash). Taxes not modeled — 1099-K applies over $2,500 in 2026.
