Gacha Calculator

$

Gacha games are popular for their randomized reward systems, but players often struggle to estimate their chances of getting desired items or characters. Our Gacha Calculator is designed to help players calculate success probabilities, expected pulls, and costs, including advanced systems like hard and soft pity.

This tool is ideal for both casual and competitive players who want to plan resources effectively and avoid overspending.

How to Use the Gacha Calculator

  1. Drop Rate (%):
    Enter the probability of obtaining the desired item per pull. For example, a 0.6% chance is entered as 0.6.
  2. Number of Pulls:
    Specify how many pulls you plan to make. The calculator estimates the probability of success over this number.
  3. Pity System (Optional):
    Select No Pity, Hard Pity (Guaranteed), or Soft Pity (Increased Rate).
    • Hard Pity: Guarantees a reward after a set number of pulls.
    • Soft Pity: Increases the drop rate gradually after a certain number of pulls.
  4. Pity Count & Soft Pity Start:
    If using a pity system, input the total pulls until hard pity or the soft pity start threshold.
  5. Current Pity Progress:
    Track your current number of pulls toward the pity counter.
  6. Cost Per Pull:
    Enter the in-game currency or real money cost for a single pull.
  7. Desired Copies:
    Enter how many copies of the item you want. The calculator estimates the number of pulls and cost required to reach your goal.
  8. Click Calculate:
    The calculator displays:
    • Success probability for at least 1 copy
    • Failure probability
    • Expected number of wins
    • Average pulls needed for 1 copy
    • Pulls needed for desired copies (90% probability)
    • Pulls until pity
    • Total cost for entered pulls
    • Estimated cost for desired copies

Example Calculation

Suppose you want a 0.6% drop rate item with a hard pity at 90 pulls. You plan 100 pulls at $1 per pull and want 1 copy.

  • Success Probability: 45.12%
  • Failure Probability: 54.88%
  • Expected Wins: 0.6 items
  • Average Pulls for 1 Copy: 167 pulls
  • Pulls Until Pity: 90 pulls
  • Total Cost: $100
  • Estimated Cost for Desired Copy: $167

This gives a clear picture of how luck and costs interact, helping players make informed decisions.
