TradeStack: TCG Calculator

TradeStack is the trade calculator Pokémon TCG collectors have been doing without. When you're negotiating a trade at your local game store, at a convention, or over Discord, you're doing mental math against prices you don't have in front of you. TradeStack ends that. Search a card, pick the variant and condition, add it to your stack, and set your trade percentage. TradeStack shows you the market value and trade value instantly. The whole session takes under 60 seconds. BUILT FOR HOW COLLECTORS ACTUALLY TRADE Collectors trade at 60–80% of market price. That accounts for liquidity and the absence of platform fees you'd pay on eBay or TCGPlayer. TradeStack has percentage presets at 60, 70, 80, 90, and 100 — tap once, everything updates instantly. CONDITION AND GRADE AWARE Raw pricing for NM, LP, MP, HP, and DMG. Graded pricing for PSA, BGS, CGC, TAG, and ACE. A PSA 10 and a raw NM copy of the same card are different trade items at different prices — TradeStack treats them that way. BUYING AND SELLING Flip the toggle and the calculator reframes instantly. Selling shows you what you're giving up. Buying shows you what you're saving. Same math, the right lens. NO ACCOUNTS. NO SETUP. TradeStack is session-only. Open it, build your stack, close it. Nothing is stored, nothing requires a login. It's a calculator, not a platform. TradeStack uses real market pricing sourced from TCGPlayer and eBay completed listings.
