How to use
This tool calculates how many attempts you need to get a rare drop in games with known drop rates. • Enter the drop rate percentage (e.g., "1" for 1% chance per attempt) • Use preset buttons for common rarity tiers: Common (50%), Uncommon (10%), Rare (5%), Epic (1%), Legendary (0.1%), or Mythic (0.01%) • Set your desired confidence level (default 90% means 90% chance you'll get the drop) • Optionally enter attempts already made to see remaining runs needed • Click Calculate to see results The calculator shows: • Main result: runs needed for your confidence level • Expected runs (mathematical average) • Median runs (50% chance) • Unlucky scenario (99% chance) • Probability table showing your chances at different attempt counts If you entered previous attempts, it shows your odds so far and whether you're getting unlucky. Each attempt is independent - previous failures don't improve future odds. Use this for farming rare items, mount drops, or any RNG-based rewards in games.
