Odds calculator
Pick a treasure and how many chests you plan to open. The calculation uses only the rates Epic has published.
Result
- Chance of finding it at least once
- 0.087 %
- Odds per chest
- 1 in 137,5000.00073 %
- Average chests until the first find
- 137,500Chests to reach 50%: 95,308
This treasure can only be obtained once.
Every chest is an independent roll with the same odds. A long run without treasure does not make the next chest more likely.
No number of chests guarantees a find. Opening as many chests as the rate suggests gives about 63%, not 100%.

What is left out of the calculation
- Whether vaults or rare chests have better odds. Epic publishes a single rate per chest.
- Whether a find is shared with the whole squad. Several outlets say so; Epic has not confirmed it.
- Whether refilled chests count the same as new ones. Epic does not say.
