RS3 · Skill Cost Calculator
Work out the gold cost to train any skill between two levels. Enter your method's XP and GP per action for the exact total — or a negative GP to see profit.
Enter your method's real rates — the XP you get per action and what each action costs (buy price of materials minus anything you get back). Current best rates live on the RuneScape Wiki and in the efficient skilling guide.
It depends entirely on the method. Take the XP needed (13,034,431 for a 99 from level 1), divide by the XP you get per action, and multiply by the cost of each action. This calculator does that for you — enter your method's XP-per-action and GP-per-action and it returns the exact total.
GP per XP is how much gold each point of experience costs you: total cost divided by total XP. It's the standard way to compare training methods — a lower gp/xp is cheaper per XP, even if the hourly cost looks higher.
Yes — gathering skills and some production methods profit. Enter a negative GP-per-action (what you make per action) and the calculator shows total profit instead of cost.
