Move the dial. The max offer moves with it.
Pick a team or a random spot, type the breaker's price and set how much of the spot's value you are willing to pay. The verdict is BID only when the price is at or under your max.

How the card break calculator works
Spot value, max offer and break results, from one set of data.
01
Break spot analytics: what a spot is worth of the box.
Spot value splits what the boxes cost across every spot by checklist value. It is a cost share, not a promise of what comes out. Beside it: how much of that value is backed by completed sales, and when it was last updated.
02
Max bid calculator: set your limit, then hold it.
Turn the dial to the share of box cost you are willing to pay. You get a max offer per team, or a max bid per random spot, with fees already taken out. BID or PASS, in one glance, on your phone, before the timer.
03
Break tracking: log what hit, keep the receipt.
After the break, log the cards and what they net. Your dashboard measures every spot against its all-in cost, fees, shipping and tax included, so next time you know where your limit should sit.
Sports card data and analytics
The data behind every number, open to you and your tools.
Checklists, pack odds, parallel ladders, completed-sale comps, price history and market trends sit behind the calculator. Pro and Breaker accounts reach the same data through our MCP server, so an AI assistant like Claude, ChatGPT or Cursor can verify a card, pull comps or log a break for you.
