About this construction calculator
The XP you need is the difference between the table value of your target and your current experience; actions are rounded up. Costs use the live Grand Exchange price of every material multiplied by the number of actions, and products are valued at the instant-sell price; the net column is what the plan costs (red) or earns (green) overall, and gp/xp divides that by the XP gained, so methods are comparable regardless of speed. Hours come from a typical actions-per-hour figure and are only a rough guide.
Methods above your current level are listed so you can plan a path; the game will not let you use them until you reach the level. Other skills: all skill calculators. Formula and sources: how it's calculated.
FAQ
What is the fastest Construction XP here?
Mahogany table (6 planks) gives 840 xp per action (level 52). Whether it is the best choice depends on today's prices: sort the table by gp/xp.
Where do the prices come from?
From the OSRS Wiki real-time Grand Exchange price API, refreshed every five minutes. Inputs are priced at the instant-buy price and outputs at the instant-sell price, so the result is conservative.
Why is a method missing?
The list has methods whose materials and products trade on the Grand Exchange, so a live cost can be shown. Untradeable methods (quests, minigames, drops) are not included.
