Arknights Pity Calculator
Enter your current pity (pulls since your last 6★ operator) and how many pulls you have saved to see your chance of getting at least one 6★ operator.
How Arknights pity works
Arknights advertises a base rate of 2% per pull for a 6★ operator. On its own that base rate would make long droughts common — so the game layers a pity system on top.
- Soft pity kicks in around pull 51: the per-pull rate starts climbing steeply, which is why most 6★ operators appear in a tight window rather than at the base rate.
- There is no hard pity guarantee in Arknights, so the base rate (plus any soft ramp) is what carries you.
This calculator models that exact behaviour with a Monte-Carlo simulation, so the percentage you see reflects the real soft/hard-pity curve, not just the flat base rate.
The math behind the odds
Without any pity, the chance of at least one 6★ operator in N pulls is:
P(at least one) = 1 − (1 − p)N
where p is the per-pull rate (2%). But Arknights raises p on every pull past 51, so your real probability accelerates dramatically once you enter soft pity — far faster than the flat formula suggests. Because of that ramp, we simulate tens of thousands of pull sessions and report how often you'd succeed, which is more honest than a single closed-form number.
How to use this Arknights pity calculator
- Enter your current pity. That's the number of pulls since your last 6★ operator (0 if you just got one or are starting fresh).
- Enter pulls available. How many pulls you can currently afford on this banner.
- Read your odds. See your chance to land the 6★ operator, plus the average pulls each 6★ operator takes.
Worked example
Starting from 0 pity with 90 pulls saved, there is no hard-pity guarantee, so even a large number of pulls only makes a 6★ operator very likely, never certain. Lower your pulls or raise your starting pity and watch the headline percentage move in real time.
Pull-planning tips
- Know your distance to pity. Without hard pity, budget generously: variance can be brutal at low base rates.
- Don't fall for the gambler's fallacy. Outside the pity ramp, each pull is independent — a long dry streak doesn't "owe" you a win.
- Compare other games with the general gacha probability calculator, or see all gaming tools.
Frequently asked questions
How accurate is this calculator?
It models the published base rate (2.0%), the soft-pity ramp that begins around pull 51. Exact internal numbers are not officially documented, so treat results as a very close estimate.
How many pulls until pity in Arknights?
Arknights has no hard-pity counter, so there is no fixed guaranteed pull — results are probabilistic. Use the calculator to see how likely a 6★ operator is for your pull count.
Does saving up improve my odds per pull?
No. Outside of soft/hard pity, each pull has the same 2% base chance. Saving pulls only increases your cumulative probability by giving you more attempts, and lets you reach the soft-pity ramp around pull 51 where rates climb.
