Honkai: Star Rail Pity Calculator
Enter your current pity (pulls since your last 5★ character) and how many pulls you have saved to see your chance of getting at least one 5★ character, including the 50/50 for the featured unit.
How Honkai: Star Rail pity works
Honkai: Star Rail advertises a base rate of 0.6% per pull for a 5★ character. 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 74: the per-pull rate starts climbing steeply, which is why most 5★ characters appear in a tight window rather than at the base rate.
- Hard pity at pull 90 guarantees the 5★ character 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 5★ character in N pulls is:
P(at least one) = 1 − (1 − p)N
where p is the per-pull rate (0.6%). But Honkai: Star Rail raises p on every pull past 74, 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 Honkai: Star Rail pity calculator
- Enter your current pity. That's the number of pulls since your last 5★ character (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 5★ character, plus the average pulls each 5★ character takes.
Worked example
Starting from 0 pity with 90 pulls saved, with 90 pulls from 0 pity you are guaranteed at least one 5★ character, 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 5★ character 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 5★ character is then the featured one for certain. So in the worst case it takes two pity cycles to secure a specific featured 5★ character. 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 74 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 Honkai: Star Rail?
Hard pity is at pull 90. From your current pity, subtract it from 90 to see how many pulls until a guaranteed 5★ character.
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 74 where rates climb.
