Zenless Zone Zero Pity Calculator
Enter your current pity (pulls since your last S-Rank agent) and how many pulls you have saved to see your chance of getting at least one S-Rank agent, including the 50/50 for the featured unit.
How Zenless Zone Zero pity works
Zenless Zone Zero advertises a base rate of 0.6% per pull for a S-Rank agent. 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 65: the per-pull rate starts climbing steeply, which is why most S-Rank agents appear in a tight window rather than at the base rate.
- Hard pity at pull 90 guarantees the S-Rank agent if you somehow reached it without one.
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 S-Rank agent in N pulls is:
P(at least one) = 1 − (1 − p)N
where p is the per-pull rate (0.6%). But Zenless Zone Zero raises p on every pull past 65, 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 — especially once the 50/50 is involved.
How to use this Zenless Zone Zero pity calculator
- Enter your current pity. That's the number of pulls since your last S-Rank agent (0 if you just got one or are starting fresh).
- Enter pulls available. How many pulls you can currently afford on this banner.
- Set the guarantee toggle. Turn on “guaranteed featured” if you lost your last 50/50, so your next top-rarity unit is the featured one for certain.
- Read your odds. See your chance to land the featured S-Rank agent, plus the average pulls each S-Rank agent takes.
Worked example
Starting from 0 pity with 90 pulls saved, with 90 pulls from 0 pity you are guaranteed at least one S-Rank agent, because hard pity forces a drop on pull 90. Whether that guaranteed unit is the featured one then comes down to the 50/50 (unless your guarantee toggle is on). Lower your pulls or raise your starting pity and watch the headline percentage move in real time.
What is the 50/50?
On a limited banner, your first guaranteed S-Rank agent has roughly a 50% chance to be the featured one. Lose that coin-flip and you get a random standard unit instead — but your next guaranteed S-Rank agent is then the featured one for certain. So in the worst case it takes two pity cycles to secure a specific featured S-Rank agent. Toggle "guaranteed featured" in the calculator to model the case where you already lost your last 50/50.
Pull-planning tips
- Know your distance to pity. From your current pity, hard pity is 90 − (current pity) pulls away — budget for that worst case.
- 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.
- Carry your guarantee. If you lose a 50/50, your next featured unit is locked in — plan banners so you don't waste that guarantee.

Frequently asked questions
How accurate is this calculator?
It models the published base rate (0.6%), the soft-pity ramp that begins around pull 65 and the hard pity guarantee at pull 90. Exact internal numbers are not officially documented, so treat results as a very close estimate.
What is the 50/50?
On a limited banner, the first guaranteed top-rarity unit has roughly a 50% chance to be the featured one. If you lose it, your next guaranteed unit is the featured one for certain.
How many pulls until pity in Zenless Zone Zero?
Hard pity is at pull 90. From your current pity, subtract it from 90 to see how many pulls until a guaranteed S-Rank agent.
Does saving up improve my odds per pull?
No. Outside of soft/hard pity, each pull has the same 0.6% base chance. Saving pulls only increases your cumulative probability by giving you more attempts, and lets you reach the soft-pity ramp around pull 65 where rates climb.
