Can someone help me understand pricing calculations better? I have been reading a bit, but the confusion is not going away.:glare: A few real life examples of calculation would be great!

Thanks a lot

Board Foot

A board foot is actually a 1 foot square piece of wood 1" thick. Consequently, a board 8' long by 8" wide by 1½" thick is 8 board feet. The math is: 96 " long x 8" wide = 768 square inches / 144 = 5.334 square feet x 1.5" thick = 8 board feet. It's almost like figuring cubic measure but not quite. As you can see, at the end you are multiplying square feet by inches thickness to get "Board Feet".

Thanks for the reply. That makes sense.
But what about a board that is 2" thick, or more? Will the cost be calculated differently, or will the price per BF simply be greater?

edp explained bft well. Length X Width divided by 144 is bft on a 1" board, then multiply for thicknesses over 1" (1.5, 2, 2.25...), hey where have I heard that before? All I did was repeat what edp said :laughing:.

For your question on price per thickness there is a "value added" number on top of the bft for thicker stock. For example 8/4 (2") is more expensive because of a number of factors, one of them being it is harder to dry. I am using round numbers here but say you pick up a 4/4" board that is 6 bft and a 8/4" board of the same species/grade/width/length that is 12 bft. The price will be higher than just double, most often.

I also charge more per bft for wider stock, anything over 12" wide is a premium for example (species vary greatly). Two 6" wide boards totaling 8 bft are cheaper than one 12" wide board that is 8 bft in most cases.

And, if you buy surfaced lumber, you will pay bd/ft based on 1 inch thickness, for example, a surfaced 1 X 12 X 8 feet long is actually 3/4 of an inch thick, but you pay the board feet just like it was a full inch, or 8 board feet. Rough sawn is typically a full inch, like 4/4, and 8/4 is a full 2 inches thick.
