Gacha Pull Pity Calculator

About this calculator

In gacha-style mobile games, “pulling” spends in-game currency for a randomized chance at a rare item or character, but most games include a pity system as a fairness backstop: a guaranteed rare drop after a fixed number of failed pulls, known as hard pity, with many games also raising drop odds gradually as pity count climbs (soft pity). This calculator takes your hard pity threshold, current pity count and cost per pull, and tells you exactly how many more pulls — and how many gems or premium currency — you'd need to guarantee hitting pity if luck doesn't cooperate first.

The tool speaks directly to mobile gacha players budgeting toward a specific character or item, whether they're planning how much to spend during a limited-time banner or deciding whether they have enough saved currency to safely pity out before a banner ends. It's also useful for players comparing the “worst-case” cost of guaranteeing a pull across different games' pity systems, since hard pity thresholds and costs vary significantly by title.
