Gacha Pity & Pull Probability Calculator
Enter the banner rules and your pulls. We calculate your exact chance to get the featured 5★, plus how many pulls you need for 50% and 90%.
The default numbers are a common example setup, not the rates of any specific game. Always copy the official rates from the banner's details page.
FAQ
What is soft pity and hard pity?
Hard pity is the pull where a 5★ is guaranteed. Soft pity is the point before that where the 5★ rate starts climbing each pull. Most modern gacha games use both.
What does 50/50 mean?
When you get a 5★, it may be the featured character or a standard one. In many games, losing the 50/50 makes your next 5★ the featured one (a guarantee).
How accurate is this calculator?
The math is exact for the rates you enter: it computes every possible outcome instead of simulating. Accuracy depends on the rates being correct for your game, so enter the official rates from the game's banner details.
Which games does it work for?
Any gacha that uses a base rate, optional soft pity, hard pity and an optional featured guarantee. Change the inputs to match the game.
