OSRS Slayer XP, Tasks, Points and Time
Estimate OSRS Slayer tasks, points, time, cost, and loot by using realistic long-run averages for your own task mix.

Use the calculator first
Open the OSRS Slayer Calculator and replace the example defaults with values for the exact OSRS activity you are modeling.
Formula and assumptions
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.
Worked example
If your goal requires 1,000,000 Slayer XP and your completed tasks average 15,000 Slayer XP, the calculator estimates 67 tasks after rounding up.
Visual explanation
The calculator includes a live result diagram and a calculation-flow diagram. They use the same inputs and outputs as the calculator rather than a separate hidden model.
Important limitations
Actual Slayer XP, points, duration, supply cost, and loot vary heavily by task, Slayer master, streak, skips, blocks, extensions, boss tasks, superior creatures, combat style, and gear. This calculator uses user-entered long-run averages and does not fetch live prices or account data.
Source
Verify method-specific values against current Old School RuneScape information before using a large cost, training, or probability plan.

Frequently Asked Questions
- What inputs matter most for this Slayer estimate?
- Use values for the exact method you plan to use, especially rate, price, success, yield, or probability inputs.
- Does this use live prices or account data?
- No. The calculator uses visible user-entered assumptions unless a field explicitly states otherwise.
- Why can actual results differ?
- Random outcomes, method execution, account unlocks, market prices, and game updates can change real results.
- Should I use best-case rates?
- Use sustainable long-run rates rather than a short perfect benchmark.
