Arknights Pull Calculator | 6★ Soft Pity & Pull Budget Odds

Important: This Arknights pull calculator is a fan planning tool with editable rates. It is not official, not affiliated with Hypergryph, Yostar, or any publisher, and cannot read your account. Banner rules, pity, and pools change—verify against in-game notices before spending currency.

Summary: Set your 6★ pity streak (pulls since the last 6★), how many more pulls you plan, and optional base 6★ rate plus soft-pity ramp. The widget runs a transparent Monte Carlo to estimate P(at least one 6★) and mean 6★ count over that window, then charts a few budget checkpoints—same spirit as other scenario tools on this site.

Arknights pull calculator (6★ soft-pity planner)

Headline math models standard headhunting-style soft pity on 6★: flat base chance until a streak threshold, then each further pull adds a configurable bump until success. Defaults match a widely cited community summary—tune them if your banner screen differs.

Model (short)
  • Streak = consecutive pulls without a 6★ before the next roll.
  • If streak < 50 (default threshold): next-pull 6★ chance = base rate.
  • If streak ≥ 50: chance = min(100%, base + ramp × (streak − 49)).
  • On any 6★, streak resets to 0 for the following pull. Monte Carlo averages many independent runs.
  • Rate-up / shared pools / spark systems are not modeled here—use the guide below for expectations.
Pull plan

0 = you just rolled a 6★ or you are tracking from a fresh banner state.

Results and charts will appear here after you run the simulation.

Monte Carlo uses a fixed trial count for repeatability (see results line). For spending decisions, cross-check pity counters in the client and read the long guide for banner-specific caveats.
