Break Spot EV Calculator

One break, both sides of the math: what the room pays versus what the box is expected to hold, and what the breaker clears after the platform's cut. Buyers and breakers are looking at the same numbers — this shows them side by side.

Picking a box fills the EV and box cost from the catalog's live numbers.

Expected value of everything in the box. Filled from the catalog when you pick a box; editing it makes the buyer-side verdict YOUR estimate, not Wildcard's.

How to read it

  • Room premium is what buyers collectively pay per dollar of expected contents. 1.0× means the room pays exactly what the cards are worth on average; the gap above 1.0× is the breaker's margin, the platform's fee, and the entertainment.
  • EV per spot divides the box EV equally. A team break's spots are NOT equal — treat this as the average seat, not your seat.
  • Break-even spot price is what the breaker must charge just to cover the box after the platform's cut — before shipping, supplies, and time.
  • A premium isn't a scam — breaks are entertainment with variance. It should just be a number both sides chose, not a surprise.
