Gacha Pity Calculator

Gacha games use a randomized loot system where players spend in-game currency — called pulls, wishes, or rolls — for a chance to obtain rare characters or items. Because base drop rates for the rarest five-star characters are typically very low (often 0.6%), most gacha systems implement a pity mechanic that guarantees a five-star reward after a certain number of consecutive failed pulls.

Understanding your pity counter is essential for planning your resources. If you are sitting at 70 pity on a banner with a hard pity of 90, you need at most 20 more pulls to guarantee a five-star — a very different situation from someone at 0 pity who might need up to 90. The gacha pity calculator on this page helps you turn that raw pity number into concrete probabilities and pull counts so you can budget wisely.

Pity systems generally fall into two categories: soft pity and hard pity. Soft pity is a zone where the drop rate begins climbing sharply with every additional pull. Hard pity is the absolute ceiling where the game must give you a five-star. Most modern gacha games — including Genshin Impact, Honkai: Star Rail, Wuthering Waves, and many others — layer both systems together to create a curve that feels fair while still encouraging spending.

Beyond simply knowing whether you will get a five-star, players also need to understand the 50/50 system. In most banners, a five-star win only guarantees the featured character 50% of the time; the other 50% gives you an off-banner standard five-star instead. However, if you lose the 50/50, your next five-star is guaranteed to be the featured character. The calculator accounts for this by letting you toggle a "Guaranteed" checkbox when you already lost your last 50/50.

By combining pity count, soft and hard pity thresholds, base rate, soft pity boost rate, planned pull count, and 50/50 win rate, this gacha pity calculator gives you a realistic featured character probability — not just the theoretical base rate printed on the banner.

The calculator derives your pull probability in three distinct regions depending on how many pulls deep you are into the current pity counter. Let n be the total pity count on a given pull attempt (current pity + pull number in the sequence).

Per-Pull Rate Function

Each pull's individual drop rate is determined by:

• If n ≥ hardPity: rate = 100% (guaranteed)
• If n ≥ softPityStart: rate = min(100, baseRate + softPityRate × (n − softPityStart + 1))
• Otherwise: rate = baseRate

Cumulative Probability

Because each pull is an independent trial with a changing success rate, the probability of getting at least one five-star across k pulls is calculated iteratively. The calculator tracks a running "no-drop probability" — the chance of having failed every pull so far — and accumulates it pull by pull.

Featured Character Probability

The final featured character chance depends on whether you have a guarantee (you lost your last 50/50):

• Guaranteed: featuredChance = cumulativeProbability × 100
• Not guaranteed: featuredChance = (cumulativeProbability × fiftyFiftyRate + cumulativeProbability × (1 − fiftyFiftyRate) × cumulativeProbability) × 100

The non-guaranteed formula covers two paths: winning the 50/50 directly, and losing the 50/50 but then also getting a second five-star (which would be guaranteed featured) within the planned pulls.

Almost every modern gacha game uses a two-stage pity system. Knowing the difference between soft and hard pity changes how you plan your pulls and when you stop or continue spending resources.

Soft pity is a range of pull counts where the drop rate increases significantly with every pull. In Genshin Impact and Honkai: Star Rail, soft pity begins around pull 74. Each pull inside soft pity adds roughly 6 percentage points to the drop rate. So by pull 80 (seven pulls into soft pity), the rate has jumped from the base 0.6% to over 42%. By pull 85, the rate exceeds 72%. In practice, the vast majority of five-stars are obtained somewhere inside the soft pity zone, which is why experienced players often say "soft pity starts at 74."

Hard pity is the absolute ceiling — the pull number at which the game's system guarantees a five-star with 100% probability. In Genshin Impact this is pull 90; in some other games it is lower (80 or even 50). Hard pity is a worst-case guarantee, not a target. Because soft pity dramatically raises the rate well before hard pity, most players never reach pull 90 in practice. However, if your pity is at 88 and you are planning only 2 pulls, knowing you are just 2 from the ceiling is crucial information.

The relationship between soft and hard pity matters most when you are close to soft pity start. If you have 68 pity and are planning 10 pulls, you will enter soft pity at pull 7 of your session (reaching pity 74). At that point, your rate will begin climbing rapidly. Entering soft pity partway through your pull session can significantly change your cumulative probability versus starting fresh at 0 pity.

This calculator computes the exact per-pull rate for every pull in your sequence, accounts for soft pity correctly from the first pull after the threshold, and gives you a precise cumulative probability rather than a rough estimate. You can also customize all thresholds to match any gacha game you play.

The expected number of pulls to obtain a five-star is the probability-weighted average across all possible outcomes. The calculator computes it as:

expectedPulls = Σ (i × P(no drop before pull i) × rate at pull i), summed from i = 1 to hardPity − currentPity

This is not the same as the hard pity number divided by 2. Because the rate is not flat — it starts very low and ramps sharply in soft pity — the expected value is biased toward the soft pity zone. For a fresh Genshin Impact banner starting at 0 pity, the expected number of pulls is approximately 62 to 65, not 45 (half of 90). This means if you are planning to pull a featured character and want a better-than-even chance, you should budget at least 60 to 70 pulls.

The expected pulls figure also depends on your current pity. If you are at pity 60, you have already "banked" progress toward soft pity, so your expected remaining pulls are much lower. The calculator dynamically adjusts expected pulls based on your current pity count, giving you a personalized estimate rather than a generic one.

For resource planning purposes, note that expected pulls represents the median scenario, not a guarantee. If you want a 90%+ chance of getting the featured character (accounting for 50/50), you will often need resources for nearly two full pity cycles — roughly 160 to 180 pulls. This is why whale and F2P resource planning looks so different: one missed 50/50 can double the cost of obtaining a character.

Use the pull probability table generated by the calculator to see exactly how your cumulative probability grows pull by pull. This table is especially useful when you have a limited number of pulls saved and want to know whether it is worth using them now or saving for a banner where you have a guarantee.

The 50/50 system is one of the most misunderstood aspects of gacha games. When a player wins a five-star from a limited banner, the game then runs a second random check: did you get the featured five-star, or an off-banner standard five-star? In most games, each outcome has a 50% chance, hence the name "50/50."

If you win the 50/50, you get the featured character directly. If you lose it, the game notes internally that you have a "guarantee" — your next five-star on any limited banner is automatically the featured character. This guarantee transfers between banners in most games, so losing the 50/50 on one banner means your next pull is guaranteed featured on the next limited banner you choose.

The calculator lets you set the 50/50 win rate (default 50%) and toggle the "Guaranteed" checkbox. When guaranteed is checked, the featured character chance equals your raw five-star cumulative probability — no 50/50 coin flip needed. When guaranteed is unchecked, the featured character probability accounts for two winning paths: directly winning the 50/50, or losing the 50/50 but obtaining a second five-star (which would then be the guaranteed featured) within the same pull session.

Some games deviate from the standard 50/50. Certain banners have a 75/25 split in favor of the featured character, or use a different win rate entirely. The 50/50 Win Rate input lets you set the exact percentage for the game and banner you are playing, making the calculator flexible across all gacha titles.

Tracking your guarantee status is just as important as tracking your pity count. Many experienced players keep a spreadsheet noting both values so they can accurately plan across multiple banners in advance.

While the default settings match the Genshin Impact and Honkai: Star Rail standard banner parameters (0.6% base rate, soft pity at 74, hard pity at 90, 6% boost per soft pity pull, 50% 50/50 win rate), the calculator is fully configurable for any gacha game.

Here are typical parameter sets for popular gacha games to help you configure the calculator accurately:

To use the calculator for a different game, simply update the Soft Pity Start, Hard Pity, Base Rate, and Soft Pity Boost fields. If a game does not use soft pity, set the soft pity start equal to the hard pity value. If the 50/50 rate differs, change the 50/50 Win Rate field accordingly.

The pull probability table updates in real time as you adjust settings, so you can immediately see how different banner configurations change your odds with each additional pull.
