Unboxing chance calculator

Calculate total chance after repeated boxes, attempts needed for a target probability, or attempts affordable within a cash budget. Results are mathematical estimates for independent attempts.

Why inputs are user-provided

Official sources do not publish crate odds, pity rules or box prices. User-provided inputs keep the calculation useful without presenting assumptions as game data.

Frequently asked questions

Is the calculator official?

No. It applies standard probability formulas to values you enter.

Does it support pity?

No confirmed pity formula is available, so the calculator assumes independent attempts.
