1. What is the WoW Drop Rate Formula?

The WoW drop rate formula calculates the probability of receiving at least one drop after a certain number of attempts. It accounts for the cumulative probability across multiple attempts.

2. How Does the Calculator Work?

The calculator uses the probability formula:

Where:

• \( p \) — Drop probability per attempt (0 to 1)
• \( n \) — Number of attempts/kills

Explanation: The formula calculates the chance of getting at least one drop after n attempts, considering the independent probability of each attempt.

3. Importance of Drop Rate Calculation

Details: Understanding drop probabilities helps players estimate how many attempts they might need for rare items and manage their expectations for farming runs.

4. Using the Calculator

Tips: Enter the drop chance as a decimal (e.g., 0.01 for 1%) and the number of attempts. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does killing more mobs guarantee a drop?
A: No, the probability approaches but never reaches 100%. Even with 100 attempts at 1% drop rate, you have only ~63.4% chance.

Q2: Are drop chances independent?
A: Yes, each attempt is independent unless specified otherwise by game mechanics.

Q3: What's the 90% confidence point?
A: For a p% drop chance, you need log(0.1)/log(1-p) attempts for 90% chance of getting it.

Q4: How accurate are displayed drop rates?
A: Community data suggests most displayed rates are accurate, but some may be rounded or outdated.

Q5: Do drop rates change with party size?
A: Generally no for personal loot, but may affect master loot or special mechanics.
