Log Prices – WNC Sawmill

The chart with log prices should be read as price per 1000 BF. In other words, if you add a decimal in front, that would be price per board foot. For example: Poplar: #1 250 would be read as $250/1000 BF or .25/BF Poplar: #3 75 would be read as $75/1000 or .075/BF. Multiply the price per BF by the scale and that is the value of your log.
