Calculators

Calculators are used to determine things like experience points, profit, and hourly rates using data such as real-time prices in the Grand Exchange Market Watch. Even if a player gathers their own materials, using the real-time market prices to measure value is best practice due to opportunity costs.

Below is a curated list of most calculators. A full list of calculators can be seen here.
