How to use this tool?
This calculator estimates the resources needed to train Construction in Old School RuneScape from one level to another.
- Set Current & Target Levels – Enter your current level (1–99) and desired target level (2–99). The target must be higher than the current level.
- Optional XP Overrides – If you have partial XP or want to stop at a specific XP amount, enter Current XP and/or Target XP. Otherwise, the calculator uses the XP at the given levels.
- Enter Action Details – Input the XP per Action (e.g., 140 for a mahogany larder), the Plank Cost per action, and any Other Material Cost (e.g., nails, saws).
- Click "Calculate" – The results show:
- Total XP needed
- Number of actions required (rounded up)
- Total plank cost, other costs, and combined total cost
Note: All costs are in gold pieces (gp). Ensure XP per action is a positive number. The calculator uses the standard OSRS XP table for levels.
