What is a Gacha Rate Calculator?

A Gacha Rate Calculator computes the probability of obtaining specific characters or items in gacha games based on drop rates and number of attempts.

How to use

Enter the drop rate percentage and number of pulls. The calculator shows your probability of success and expected pulls needed.

Frequently Asked Questions

What is a Gacha Rate Calculator?

This tool calculates the statistical probability of obtaining specific items (characters, weapons, or cards) in 'gacha' games. It uses drop rates, pity systems, and the number of pulls you plan to perform to estimate your odds.

How does the Pity System work?

The pity system guarantees a high-rarity item after a certain number of failed pulls. If the base drop rate is 0.6%, the calculator factors in that you are guaranteed the item (usually at 'Hard Pity') after a set number of pulls, dramatically increasing your overall chances.

What is Soft Pity?

Soft Pity is a threshold before the Hard Pity limit where the drop rate begins to increase gradually. For example, if Hard Pity is 90 pulls, Soft Pity might start at 75 pulls. The calculator approximates this rate increase to give you a more accurate percentage.

How do I use the 50/50 or 75/25 settings?

Many games have a 'spike' rule where, if you win a high-rarity item, there is a chance (usually 50% or 75%) it is the featured promotional character rather than a standard character. Toggle this to calculate your odds of getting the specific character you want.

Why is the result not 100% even if I have enough currency for Hard Pity?

Unless you are exactly at the Hard Pity count (e.g., the 90th pull), there is always a mathematical chance you do not receive the item in fewer pulls. The calculator provides the cumulative probability of success *within* that specific number of pulls.

Can this calculator predict my luck?

No. Gacha systems are based on RNG (Random Number Generation). This tool shows statistical averages and probabilities over a large number of players, not the outcome of your specific personal account.
