About OldSchoolCalc

An independent project for Old School RuneScape players who want clearer ways to plan their next goal.

What we are building

Our focus is practical calculators and supporting guides: drop probability, XP gaps, materials and training costs. A useful answer should explain the inputs and assumptions as clearly as the result.

Our approach

We aim to keep tools focused, make limitations visible and distinguish expected estimates from guaranteed outcomes.

Accuracy and corrections

Game mechanics and prices can change. Our methodology page explains how we document calculations and their assumptions. Check the assumptions and relevant source when reviewing a result.
