Construction Calculator
Pick a training method, enter your current Construction XP and a target level, and see how many builds -- and planks -- it takes.
XP for level 50
101,333
Builds needed
62
mahogany planks needed
372
How it's calculated
builds needed = ceil( (XP for target level − current XP) / XP per build )
planks needed = builds needed × planks per build
Worked example
The calculator's own defaults: 50,000 Construction XP, building Mahogany table (dining room) (840 xp, 6 mahogany planks each), targeting level 50.
| XP required for level 50 | 101,333 |
| XP still needed | 51,333 |
| Builds needed | 62 |
| mahogany planks needed | 372 |
Frequently Asked Questions
How is Construction different from other skills here?
The math is identical to the Skill Training Calculator (actions needed = XP gap / XP per action) -- Construction just gets its own page because each build action also consumes a specific number of a named plank, so the useful output is a plank count, not just an action count.
Are the preset build methods realistic training methods?
They're a small, typed-from-memory list of common build-and-remove training actions and their approximate XP and plank costs -- a real, efficient training plan usually also factors in gold cost per XP, which this calculator doesn't model. Confirm current costs before committing to a method.
Why is the plank count not the same as the build count?
Different build actions consume different numbers of planks -- a simple item might need one plank, a larger piece of furniture several of a more expensive type. The calculator multiplies builds needed by the selected method's planks-per-build to give a real shopping-list number.
