See what every card in your break actually sells for on eBay. Raw and PSA 10 values, always up to date. No more guessing what a card is worth.

The Break Calculator uses real card values to generate team slot prices. Your costs, your profit margin, your platform — fair prices backed by data, not guesswork.

Watch how card values move over time with price history charts. See which cards are rising, which are cooling off, and make better decisions about when to chase in a break.

Track cards you're interested in buying and pull live eBay listings on demand, each shown as how far below market it sits so deals stand out. Plus a grading scanner that surfaces cards where the PSA 10 is worth 2× the raw — your best buy-and-grade candidates.

Log the boxes, raw cards, and graded cards you own — what you paid versus what they're worth now, with profit and loss tracked over time. Your whole collection's value, always current, in one place.

Football, basketball, baseball, and Pokémon — every team, every set. Whether you're breaking Topps Chrome, Donruss Optic, or your favorite Pokémon sets, BreakLogic has you covered.
