The price of firewood is affected by its dryness, location and energy content. Other important factors in cost include the size of the bundle being purchased and the distance it was transported.
Soft woods such as poplar and spruce do not produce as much energy per cord as hardwoods such as white oak or iron wood, so hard woods cost more per cord than soft woods. Even though soft woods are less expensive, the cost of transportation and storage is the same for all wood species. Transportation and storage also affect the cost of firewood sold in urban areas, which is at least double that of firewood sold in rural areas.
Wood that has been stored for a longer period of time tends to be dryer and more expensive. Green wood is not as dry and is therefore less expensive, since it doesn't burn as well. In addition, the smaller the pieces of wood per cord, the more expensive it is, since smaller pieces require additional handling and labor.
Cost also depends on where the bundle is purchased. Wood suppliers have the best deals for a full cord and usually allow customers to have access to the storage area to ensure they are buying quality wood. Convenience stores, grocery stores and smaller retailers charge more and do not usually sell full cords.
