Plank making calculator[edit source]
The table below lists the profit (or loss) made from buying logs, having them converted into planks by the sawmill operator and selling the planks. For those interested in the costs associated with the Lunar spell Plank Make, please see the spell's main page. The prices are based from Grand Exchange Market Watch/Woodcutting and Grand Exchange Market Watch/Construction.
Please note: Loss will have the - sign next to the amount of GP, if it doesn't have that then it is a profit.
