Overview

Deterministic spot pricing, fee auditing, and weighted tier allocations for live card breakers.

BreakerCalc Pro is the essential, deterministic spot-pricing engine and profit auditor built specifically for live card breakers and hobby streamers. Whether you are breaking cases of NFL, NBA, MLB, Pokémon, or Magic: The Gathering across Whatnot, TikTok Shop, or eBay Live, pricing your spots incorrectly eats into your margins fast. BreakerCalc Pro eliminates guesswork, factor-in platform fee drag, overhead, and case costs in real time, giving you exact floor prices and mathematically sound Pick-Your-Team (PYT) distributions. KEY FEATURES & LIVE STREAM WORKFLOWS ⚡ Instant Spot Break-Even Solver • Input your sealed case/box cost, supply overhead per spot, and target net dollar profit. • Automatically computes the exact required floor price per spot for 32-team, 30-team, 8-division, 6-division, or custom 16-spot breaks. ⚡ Pre-Loaded Multi-Platform Fee Models • Whatnot: 8.0% commission + 2.9% + $0.30 processing per transaction. • TikTok Shop: 8.0% commission + 2.9% + $0.30 processing. • eBay Live: 13.25% all-in fee structure + $0.40 per order. • Custom Mode: Flat 10% processing toggle for independent off-platform/invoice breaks. ⚡ Weighted PYT (Pick-Your-Team) Value Generator • Moving away from randoms? Instantly distribute your total required gross revenue across 4 strategic tiers: Tier 1 (Super Chase - 4 Spots): 40% of total pool value. Tier 2 (Contenders - 8 Spots): 30% of total pool value. Tier 3 (Mid-Tier - 10 Spots): 20% of total pool value. Tier 4 (Floor/Value - 10 Spots): 10% of total pool value. ⚡ 1-Click Live Stream Clipboard Exporter • Click one button to format and copy your complete break breakdown directly to your clipboard. • Paste clean break notes, pricing summaries, and tier guides directly into your stream chat, community Discord, or listing descriptions. ⚡ Zero-Latency & Local Memory • 100% client-side calculation engine with instant input responsiveness. • Automatically remembers your last inputs via local browser storage—ready the moment you click the icon on your toolbar. WHO IS THIS FOR? • Sports card streamers breaking sealed cases of Topps, Panini, Bowman, and Upper Deck. • TCG box breakers opening Pokémon, One Piece, Yu-Gi-Oh!, and Magic: The Gathering booster boxes. • Resellers seeking clean, accurate risk allocation before committing capital to distributor pre-orders. PRIVACY FIRST BreakerCalc Pro runs entirely inside your browser. No user tracking, no external API calls, and zero data leaves your local machine.
