Anime Origins Calculator

Use this working summon probability calculator: enter a per-pull rate and pull count to see at-least-one odds, no-hit odds, expected successes, and the visible formula.

Inputs

Output

Recommendation

Claim listed codes first, then spend rewards only after you know which upgrade path stays useful.

Use exact game rates when they are available. Until then, treat this as a conservative planning helper.

Summon probability calculator

Enter the rate shown on your current banner. This tool does not assume an official rate or a pity guarantee.

Formula: 1 − (1 − p)n. Expected successes: n × p. Results are mathematical estimates from your inputs, not official Anime Origins odds.

Summon planning

Use visible banner odds, not guessed Anime Origins rates

The safest way to use this calculator is to copy the percentage shown on the current in-game banner, enter the number of pulls you can afford, and treat the result as a planning estimate. The official Roblox page confirms Anime Origins includes summons, upgrades, evolution, Story, Infinite, Raids, challenges, and team building, but it does not publish a universal summon-rate table on the public Roblox listing.

If a guide, video title, or code tracker mentions a rare unit, a new code, or a banner target, treat it as a reason to double-check in game. Do not convert it into a rate, pity rule, or guaranteed pull path unless the game screen or creator-owned source shows the exact value.

Decision checklist

Before spending gems or rerolls

  • Check the current banner screen for the exact per-pull percentage.
  • Redeem listed codes first, because gems and rerolls can change your pull count.
  • Run the calculator once for your current pulls and once for the pulls you can farm today.
  • Stop if the banner does not show the rate, pity state, or reward pool clearly.
What this tool answers

Probability, pity, and source boundaries

At-least-one odds

Use this when the banner lists a rate and you want to know how likely one target hit is over a pull session.

No-hit risk

Use the no-hit number to decide whether to keep saving, farm codes and dailies, or spend only part of your currency.

Pity rules

Leave pity out unless Anime Origins shows a pity counter or official source. A community claim alone is not enough for an exact formula.

Turn pull odds into a roster plan

Browse unit roles after estimating your summon chance.

Verify banner assumptions

Check the data boundary before entering a current banner rate.
