Rates are best case. Experience per hour assumes a demon butler and good execution. Ordinary play is slower. The wiki publishes no rate for methods marked ~: below level 40 you cannot hire a servant, so those assume 1,600 planks an hour carried yourself. The Mahogany Homes calculator plans contracts tier by tier. Method data checked against the OSRS Wiki on 30 August 2026. Prices are live.
