IdleMMO Construction Calculator
Every construction resource ranked by XP/hr and gold/hr — pick the best one for fast levels or profit.
Construction 1-100 leveling route →
UpdatedConstruction is a crafting skill: turn raw materials, logs and bars into planks, beams, bricks, glass and fittings to earn Construction XP plus a little Strength XP. Most builds consume materials, so the real profit is what the finished build sells for minus what its inputs cost. The table below ranks each build by XP per hour and by NET gold per hour after material cost, so you can pick the best build for fast levels or real profit.

Enter where you are and where you want to be — see exactly how many actions, how long, and what materials it takes.
Per-level XP requirements are community-sourced estimates — IdleMMO does not publish an official XP curve, so treat action and time totals as close approximations, not exact figures.

The Materials column shows what each craft costs. Net profit (sale − materials) is shown only where a live market price exists for the output — crafted gear isn't meaningfully sold to vendors, so we show “—” rather than a misleading vendor-based loss. Live market pricing is coming to fill these in.
