Assumes independent pulls with pity mechanics: base rate, optional soft pity ramp, hard pity guarantee, and 50/50-style featured logic.
What this pity calculator does
If you play gacha games, you already know the emotional roller coaster of “just one more pull.” This pity calculator helps replace guesswork with numbers. You can estimate your probability of getting a featured unit or item based on your current pity, planned pulls, and banner rules.
The model supports common systems: a base top-rarity rate, soft pity that increases the rate after a threshold, hard pity that guarantees a top-rarity hit, and a featured split (like a 50/50).
How the calculator models pity
1) Base probability
Each pull starts with a base chance of hitting top rarity. For example, 0.6% means most pulls fail, but over many pulls your cumulative chance grows.
2) Soft pity ramp
After the soft pity starting pull, the calculator increases the top-rarity rate by your specified increment per pull. This mimics banners where odds rise rapidly late in the cycle.
3) Hard pity guarantee
At hard pity, top rarity becomes guaranteed. This prevents infinite bad luck and strongly shapes long-run expected outcomes.
4) Featured vs off-banner logic
When you hit top rarity, the result may or may not be featured. If your game has a guarantee after losing a featured coin flip, check the “Guaranteed featured” box when applicable.
How to use it well
- Enter your exact current pity before you begin pulling.
- Use realistic planned pulls (not wishful pulls).
- Set target copies to your actual goal (1 copy, 2 copies, etc.).
- Try multiple scenarios: “What if I stop at 60?” vs “What if I go to 120?”
Interpreting the output
The most important number is usually your chance to reach your target copies. A 75% chance can still fail one out of four times. A 95% chance is strong, but not certain. Probability helps planning; it does not remove randomness.
The distribution lines (“exactly 0,” “exactly 1,” “at least N”) are useful for budget planning. If your chance of ending at zero is still high, that is a warning to wait, save more currency, or lower your target.
Strategy tips for smarter pulls
Set a hard budget before rolling
Decide your pull cap before emotions kick in. The best pity plan is one you can afford without stress.
Use pity carryover intentionally
If your game carries pity between banners, partial progress can be valuable. You do not always need to force a full cycle right now.
Know your risk tolerance
Some players are comfortable with 60% odds. Others want 90%+ before committing. Neither is “correct”—just be intentional.
Quick FAQ
Is this exact?
It is exact for the rules you enter. If your game has extra mechanics (separate weapon pity paths, fate points, multi-banner pools, spark systems), results are an approximation unless those mechanics are included.
Why can I still fail with high odds?
Because randomness has tails. Even a 90% success rate fails 1 out of 10 attempts on average.
Can this help me spend less?
Yes. Seeing your real odds usually encourages better stopping rules and fewer impulse pulls.
Final thought
A pity system is designed to reduce extreme bad luck, not eliminate uncertainty. Use this calculator to plan like an adult: define a target, define a budget, and stop when your plan says stop.
