HSR warp calculator. Your exact odds of pulling the featured 5★ character or Light Cone.

An HSR warp calculator tells you the exact probability of pulling the featured 5★ within your warp budget. It handles the 0.6% character base rate, the 0.8% Light Cone rate, soft pity, hard pity, the 50/50 on characters, and the 75/25 on Light Cones — both with the lose-next-win-after failsafe.

What is the Honkai: Star Rail pity system?

The Honkai: Star Rail pity system is the set of guarantees HoYoverse bakes into each Warp banner so you never pull forever without a 5★. Every warp has a small flat base rate until you hit soft pity, where the rate ramps sharply, and a hard pity that forces a 5★ on a specific warp. On top of that, event banners add a featured split that decides whether the 5★ you pulled is the current banner unit or a standard one.
The Character Event Warp runs on 0.6% base rate, soft pity around warp 75, hard pity at warp 90, and a 50/50 featured split with a failsafe: lose the 50/50 and your next 5★ is guaranteed to be the featured character. Two hard-pity cycles (180 warps) will always give you the featured character.
The Light Cone Event Warp uses different numbers: 0.8% base rate, soft pity around warp 65, hard pity at warp 80, and a 75/25 split in favor of the featured Light Cone. Per HoYoverse's own support article, if you lose the 75/25 the next 5★ Light Cone is guaranteed to be the featured one, capping the worst case at 160 warps. The Stellar Warp (standard banner) has no featured concept — every 5★ comes from the permanent pool.

How to calculate your HSR warp odds

To use this HSR warp calculator:
1. Pick the banner: Character Event Warp, Light Cone Event Warp, or Stellar Warp (standard). Pity is tracked separately for each, so pulling on Light Cone does not touch your character pity.
2. Enter your current pity — the number of warps since your last 5★. Check it in-game under Warp → Details → History.
3. On the Character banner, toggle "Guaranteed featured" if your previous 5★ was not the featured character. That locks the next 5★ as the featured unit.
4. Enter your warp budget. You can type warps directly, or enter Stellar Jade plus Special Passes — the tool converts at 160 Stellar Jade = 1 warp.
5. Read the output: probability of the featured 5★, probability of any 5★, expected warps to first featured, and the budget breakpoint where you cross 50%, 75%, and 99%.
The calculator is free, runs fully in your browser, and keeps no data. You can bookmark the URL with your pity pre-filled to check back every patch.

HSR per-warp probability formula

P5⋆(n)={r0n<sr0+k⋅(n−s+1)s≤n<h1n=hP_{5\star}(n) = \begin{cases} r_0 & n < s \\ r_0 + k \cdot (n - s + 1) & s \le n < h \\ 1 & n = h \end{cases}
  • nn = Warp index since your last 5★ (1-indexed).
  • r0r₀ = Base rate. 0.006 on Character and Stellar Warp, 0.008 on Light Cone.
  • ss = Soft-pity start. Warp 75 on Character/Stellar, warp 65 on Light Cone.
  • hh = Hard pity. Warp 90 on Character/Stellar, warp 80 on Light Cone.
  • kk = Soft-pity ramp. Roughly 10 × r₀ per warp.
This piecewise per-warp rate is then composed with the featured split — 50/50 on Character, 75/25 on Light Cone — and the guaranteed-featured failsafe to give the probability over a full warp budget. The calculator evaluates this exactly using a dynamic program over (pity, guaranteed) states rather than simulating rolls, so results are deterministic and reproducible across sessions.

HSR warp examples

Character banner, pity 0, 90 warps, 50/50 active

You start from pity 0 with exactly one hard-pity cycle (90 warps) and the 50/50 still active. P(any 5★) is 100% because you are guaranteed to hit hard pity. P(featured 5★) lands at roughly 56–60% — you win the 50/50 outright about half the time, and in the fraction of cases where you pull an early 5★ you may still have enough budget for a second 5★ on the failsafe.

Light Cone banner, pity 0, 80 warps

Eighty warps guarantee at least one 5★ Light Cone via hard pity, but only the 75/25 split decides whether that 5★ is the featured Light Cone. P(featured) is approximately 78% — the base 75% plus a small boost from the rare case where you get an early 5★ and have warps left for the failsafe. If you need a strict guarantee, you have to budget two cycles.

Light Cone banner, 160 warps — the strict guarantee

160 warps is the worst-case guarantee for the featured Light Cone. Two full hard-pity cycles of 80 warps each give you at least two 5★ Light Cones; if the first is not the featured one, the failsafe locks the second as featured. P(featured) = 100% at 160 warps, which is why community guides often quote "160 warps = guaranteed Light Cone."

Character banner, pity 60, lost last 50/50, 40 warps

You are 15 warps from soft pity with the guarantee already active. Any 5★ you pull is guaranteed featured. With 40 warps the calculator returns P(featured) ≈ 99% — you will almost certainly hit a 5★ inside the soft-pity ramp, and it is guaranteed to be the featured character because of the failsafe.

Budget comparison table (Character banner, pity 0, 50/50 active)

The table below shows how the probability of the featured 5★ character scales with your warp budget on the Character Event Warp, starting from pity 0 with the 50/50 still active.

Use the 180-warp row as your "I must have this character" budget on the Character banner.

Tips for planning your HSR warps

  • Commit to the 180-warp character budget before you start pulling. Two full cycles are the only mathematical guarantee for a featured 5★ character, and stopping at 90 after losing the 50/50 is the most common way F2P accounts run dry.
  • On the Light Cone banner, plan for 160 warps if the Light Cone is a must-have signature for your main DPS. One cycle (80 warps) only gives you about 78% odds — acceptable for quality-of-life Light Cones, risky for DPS multipliers that carry your entire team.
  • Never pull from pity 0 on a character you are unsure about. Expected warps to the first 5★ is around 62–64 on the Character banner, so half of your 90-warp budget vanishes just getting to the 50/50 roll.
  • If your result card shows P(featured) below 40%, you are gambling, not planning. Either push your budget higher, or skip to the next banner and stack Stellar Jade. Most players quote 70% as the comfortable threshold for a single-banner pull.
  • Pity carries over between Light Cone Event Warps. If you lost a 75/25 on the previous Light Cone banner, your next 5★ on any future Light Cone Event Warp is still guaranteed featured.
  • Stellar Jade converts at 160 Jade per warp. When budgeting, subtract the Special Passes you already own first, then convert the remaining Jade — this avoids double-counting currency the tool pulls from both sources.
  • Losing the 50/50 to another Himeko stings, but the failsafe banks it. Your next 5★ is yours. Two cycles, no exceptions — stopping at pity 90 just wastes the bank.

Frequently asked questions about HSR warps

How many pulls for a 5★ in Honkai: Star Rail?

Hard pity on the Character banner is 90 warps and on the Light Cone banner is 80 warps. Soft pity starts around warp 75 (Character) or 65 (Light Cone), where the drop rate climbs sharply. The average first 5★ lands between warps 75 and 85.

Does the Light Cone banner have a 50/50?

No, it has a 75/25. Every 5★ Light Cone has a 75% chance to be the featured one. If you lose the 75/25, the next 5★ Light Cone is guaranteed to be the featured one, so the worst case is 160 warps total.

What is the soft pity start in HSR?

Warp 75 on the Character Event Warp and Stellar Warp, and warp 65 on the Light Cone Event Warp. From that warp onwards the 5★ rate ramps roughly 6% per warp on the character banner and 8% per warp on the Light Cone banner.

Is HSR pity shared across banners?

No. Character, Light Cone, and Stellar Warp pity counters are completely independent. Pity does carry over between consecutive Light Cone Event Warps of the same type, and the same is true for Character banners, but the three types never mix.

How many warps to guarantee the featured 5★ character?

180 warps. One hard-pity cycle (90 warps) covers the case where you win the 50/50, and a second cycle (another 90 warps) covers the failsafe if you lose the first 50/50. At 180 warps the probability of getting the featured character is 100%.

How many warps to guarantee the featured Light Cone?

160 warps. Two hard-pity cycles of 80 warps guarantee two 5★ Light Cones; if the first is not the featured one, HoYoverse's failsafe locks the second as the featured Light Cone. At 160 warps the probability is 100%.

Is this HSR warp calculator accurate?

Yes. The base rates (0.6% character, 0.8% Light Cone), soft pity thresholds, hard pity thresholds, and featured splits match the values published by Game8 and ONE Esports. The math is validated against 100,000-trial Monte Carlo runs for every banner and every pity state.

Is the calculator free?

Yes. No sign-up, no tracking, no data sent to a server. Everything runs in your browser and your pity values stay on your device.

My result shows 60% featured — is that a good number?

60% is a coin flip with a slight edge. Most HSR guides recommend saving enough to reach at least 80%, which on the Character banner means around 140 warps from pity 0 with the 50/50 active. Below 50% you are in pure gamble territory.

HSR warp glossary

Warp

The HSR name for a single pull on a banner. One warp costs 160 Stellar Jade or 1 Special Pass / Star Rail Pass.

Pity

The counter of warps since your last 5★. Banner-scoped and persists across patches on the same banner type.

Soft pity

The ramp in 5★ drop rate that starts at warp 75 (Character) or 65 (Light Cone). Most 5★s drop inside this range.

Hard pity

The guaranteed-5★ warp at pity 90 (Character / Stellar) or 80 (Light Cone).

50/50

The 50% chance a 5★ pulled on the Character Event Warp is the featured character. Losing it guarantees the next 5★ is featured.

75/25

The 75% chance a 5★ pulled on the Light Cone Event Warp is the featured Light Cone. Losing it guarantees the next 5★ Light Cone is featured, capping the worst case at 160 warps.

Stellar Jade

HSR's base premium currency. 160 Stellar Jade = 1 warp.

Special Pass

Event warp ticket. 1 Pass = 1 warp on the Character or Light Cone Event Warp.

Star Rail Pass

Standard warp ticket for the Stellar Warp. 1 Pass = 1 warp on the permanent banner.
