Choose a source-labelled Anime Origins trait or enter a custom live rate to estimate hit chance, zero-hit risk, expected results, and reroll budget.
The calculator finds your chance of at least one target result, the risk of getting none, the expected hit count and an optional total resource budget. Tracked traits also show their sources, confidence and pity caveat beside the input.
Rates and reroll rules can change. Community-reported presets are a convenience, not an official table. Override the percentage with the live game value whenever it differs.
Reported data or your custom rate
Choose a tracked trait to fill its community-reported rate and sources, or switch to a custom value from your live game.
For chance p and rerolls n, the chance of at least one hit is 1 − (1 − p)ⁿ. Zero-hit risk is (1 − p)ⁿ, expected hits are p × n, and budget is n × cost.
A result is only as reliable as the percentage entered. Do not borrow rates from another game or an old update.
Expected hits describe repeated budgets across many trials. Any one set of rerolls can finish above or below that average.
Choose a maximum budget before rerolling. Recalculate if the displayed rate, cost or pool changes.
Choose a tracked trait to use its clearly labelled community-reported rate, or override it with the percentage displayed in your current game.
No. It estimates repeated independent attempts. Reported pity notes are shown, but the calculator never adds an unverified pity rule.
It is the long-run average across many comparable budgets, not a promise for one player.
Resource names and costs have not been directly confirmed, so the calculator accepts the current value you see.
Yes. The calculator accepts percentages down to four decimal places and keeps extra precision for small results.
