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 5,486,457 gp in total loot — about 814,396 gp per hour at 19 kills per hour. The biggest earner over that stretch is Wine of Zamorak at about 596,114 gp.

Each kill has a 0.7813% chance at Dragon chainbody. Half of all players get it within 89 kills, 294 kills covers 90%, and 588 kills covers 99% — so going past 128 kills without one is unlucky, but not unusual.

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