How the OSRS Slayer Calculator Works

See the calculation flow used by the OSRS Slayer Calculator.

Flow diagram explaining how the OSRS Slayer Calculator converts user inputs into its main results.
The calculator keeps rates, prices, averages, and probability assumptions visible instead of hiding them.

How the OSRS Slayer Calculator works

XP remaining equals target XP minus current XP. Tasks needed equal XP remaining divided by average XP per completed task and rounded up. Points earned multiply tasks by average points per task. Time divides tasks by tasks per hour. Total task cost and total loot value multiply their per-task averages by tasks needed, and net value subtracts cost from loot value.
