Break ROI Tracker

A break ROI tracker logs every group break you participate in — the product, team spot cost, and every card you pull with its estimated value. It calculates your running profit or loss, ROI percentage, and lifetime stats so you can see whether breaks are profitable for you over time. Most breakers lose money without tracking, so this tool helps you make data-driven decisions about which breaks to join.

Use recent eBay sold prices (not listings) for the most accurate values. Search for the exact card — player, year, set, parallel, and condition — and look at the last 3-5 sales. For base cards worth under $1, you can enter $0.50 or $0 and focus on tracking your hits (autos, relics, numbered parallels). The goal is a reasonable estimate, not perfection.

Breaking even (0% ROI) is actually above average for most break participants. The break host takes a margin, so the average participant loses 20-40% of their spot cost. If you are consistently above -10% ROI, you are picking good teams. Positive ROI usually requires hitting a big card occasionally or consistently buying undervalued team spots.

Yes, all break data is stored in your browser's localStorage. It persists between sessions on the same device and browser. No account or sign-up is required. You can export your complete break history to your clipboard at any time, or clear all data to start fresh.

It depends on your goal. For a realistic P&L picture, include everything — even base cards worth $0.25 each. But for a simpler workflow, many breakers only log cards worth $2+ and accept that base cards are essentially worthless. Either approach works as long as you are consistent across all your breaks.
