Enter a drop rate and your kill count. Each kill is an independent roll, so the chance of still having nothing after n kills is (1 − 1/rate)ⁿ.

The calculator runs in your browser at https://osrsgrandexchange.com/dry-calculator.

## Questions

### Am I dry if I pass the drop rate?

Not by much. At exactly the drop rate (say 5,000 kills on a 1/5,000), about 37% of players still have nothing. At twice the rate it is about 13.5%, and at three times about 5%.

### Does killing more make the next drop more likely?

No. Each kill is a fresh roll at the same rate. Past kills only change how unlikely your streak was.
