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 270,018,920 gp in total loot — about 8,438,091 gp per hour at 5 runs per hour. The biggest earner over that stretch is Avernic treads at about 146,094,858 gp.

Each run has a 0.625% chance at Avernic treads. Half of all players get it within 111 runs, 368 runs covers 90%, and 735 runs covers 99% — so going past 160 runs without one is unlucky, but not unusual.

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