What you actually get
Most boxes land well below the average. Chase cards pull the mean up — your typical box is the median, not the EV.
- Floor (10%)
- $86.44
- Typical
- $132
- Average (EV)
- $143
- Lucky (90%)
- $216
The average box ($143) is $11.21 above a typical box ($132) — 8%of the EV comes from above-median outcomes you probably won't see.
Pack vs box economics
Should you buy a sealed box or individual packs? EV per pack is the same either way; the question is what you pay per pack.
- Box price
- $299
- Standalone pack listing
- $34.95
- Implied pack (box / packs)
- $24.91
- EV per pack
- $11.94
- $143 / box
- Return opening box
- −52%
- Return buying packs at listing
- −66%
The box is the better deal per pack ($24.91 vs $34.95 listing). Still a losing bet on average at −52% return.

The odds
- P(box ≥ box price)
- 1.1%
- P(box ≥ expected value)
- 42.0%
- Typical box (median)
- $132
- Average box (EV)
- $143
- Unlucky box (10th pct)
- $86.44
- Lucky box (90th pct)
- $216
- God box (99th pct)
- $303
Roughly 1% of boxes return more than the $299 you paid. You'd need to open about 273 boxes (~$81,608) for a 95% chance that even one of them breaks even. A typical box (median $132) is $11.21 below the $143 average - most of the EV lives in chase cards you probably won't pull.
Where a box's value comes from
Expected contribution of each booster slot to the $143 box EV. Cards valued under $0.25are treated as $0 bulk, since penny commons and foils can't realistically be sold at their listed price.
