About OSRS Calc

What the site provides

OSRS Calc is an independent collection of browser-based tools for planning skill training, comparing combat setups, checking drop odds, following Grand Exchange prices and keeping personal goals. Calculators run in your browser and do not require an account.

The tools are intended to help compare options and estimate time or cost. They are not a game client, do not interact with game servers, and do not guarantee a particular result in game.

How estimates are maintained

Experience thresholds use the game's published progression formula. Training rates, item prices and encounter assumptions are estimates based on cited community references and public data. Actual results vary with account unlocks, equipment, attention, world conditions, market movement and updates to the game.

Pages identify important assumptions and link to references where available. If you find a stale figure, broken calculation or unclear assumption, send the page URL and details to [email protected].
