Frequently Asked Questions
What is the Loot Box Probability Calculator?
This tool helps you determine the likelihood of receiving specific items from loot boxes or gacha games based on drop rates and the number of attempts you plan to make.
How do I calculate my chances of getting an item at least once?
Enter the drop rate of the item (as a decimal, e.g., 0.02 for 2%) and the number of loot boxes you intend to open. The calculator uses the cumulative probability formula to determine the chance of obtaining the item at least once.
What is the difference between 'At Least One' and 'Exactly X' results?
'At Least One' calculates the probability of getting a specific item one or more times within your attempts. 'Exactly X' calculates the odds of obtaining the item a specific number of times (e.g., getting exactly 3 legendary items in 100 pulls).
Why does my percentage not reach 100% even after many attempts?
Probability is not a guarantee. Unless the drop rate is 100% or you have infinite attempts, there is always a mathematical chance (however small) that you will not receive the desired item. The calculator simply measures the likelihood, not the certainty.
Can I calculate probabilities for items without pity systems?
Yes, this calculator assumes independent probability for every attempt. It does not automatically account for 'pity systems' or 'bad luck protection' where drop rates increase after a certain number of failures unless you manually adjust the input rate.
What format should I use for the drop rate input?
Please enter the drop rate as a decimal between 0 and 1. For example, if the game lists a drop rate of 5%, enter '0.05'. If the rate is 0.5%, enter '0.005'.
