Pack odds calculator
Quick answer
If an estimated pull rate is 1 in 100 packs, opening 100 packs does not guarantee the card. It means the statistical chance of at least one hit is about 63%, assuming independent odds. This calculator does that math for any rate and pack count.
Stats help set expectations. They do not change your odds or guarantee results.
Accepts “1 in 100”, “1/100”, “1%” or “0.01”. Use an observed estimate — remember it is not an official or guaranteed rate.
Estimated result
At an estimated rate of ≈ 1 in 100 packs (1.00% per pack), opening 36 packs gives a statistical chance of 30.4% of at least one hit, with about 0.36 expected hits on average.

Estimates, not guarantees
Pull statistics are estimates based on available data and may vary. Opening packs is random. No pack, box, or sealed product guarantees a specific card unless the product explicitly states it.
Always check official product details and set lists before buying.
How the math works
With a per-pack probability p and n packs, the chance of at least one hit is 1 − (1 − p)n. Each pack is independent — previous packs never change the next pack's odds, and no number of packs reaches 100%.

Frequently asked questions
How does the pack odds calculator work?
If the estimated pull rate per pack is p and you open n packs, the chance of at least one hit is 1 − (1 − p)^n, assuming independent packs. For example, at an estimated 1-in-100 rate, opening 100 packs gives roughly a 63% chance of at least one hit — not a guarantee.
Does opening more packs guarantee the card?
No. More packs raise the statistical chance of at least one hit, but every pack stays random. A 90% chance still means missing about 1 time in 10. No number of packs guarantees a specific card unless the product explicitly states it.
Where do the pull rates in the calculator come from?
You can type any estimated rate, or start from one of our observed datasets. Each dataset shows its source, sample size, collection method and confidence level. None of them are official odds unless marked official.
Collect responsibly
Open packs for fun and collecting. If you need a specific card, compare the cost of buying the single.
