Calculating Timber Prices: A Formula For Sawmills

23-01-2020· While prices in the state or region reflect the typical rate, local market conditions are more consequential. Case in point: if the timber you're looking at grows near several mills, it may command a higher price than if your mill were the only one nearby. The value of a timber depends on the species, size, and quality of the trees.
