About On Drop Rate

On Drop Rate helps you check roughly how long you'd need to grind for an item, and whether you're actually dry right now, or just feeling like it.

We're passionate OSRS players, grinding since the game's 2013 release across multiple accounts and every seasonal game mode along the way.

This vibe-coded project is built and maintained by us.

Greetings from Team On Drop Rate.

Additional information

During this grind you will also be making roughly 10,448,613 gp in total loot — about 761,878 gp per hour at 28 kills per hour. The biggest earner over that stretch is Dragon bones at about 941,040 gp.

Each kill has a 0.2604% chance at Sarachnis cudgel. Half of all players get it within 266 kills, 884 kills covers 90%, and 1,767 kills covers 99% — so going past 384 kills without one is unlucky, but not unusual.

Loot values use live Grand Exchange prices and shift with the market.
