The Total Cost of Rafter Boards calculator computes the cost of lumber based on the unit price and the number of rafters required for a two sided roof.

INSTRUCTIONS: Choose your preferred units and enter the following:

• (L)  The length of the ridge line.
• (oC) The on-center spacing.
• (uP) The unit price of the boards (see below)

Total Cost:  The calculator computes the number of rafters in the roof and applies the unit price to compute the total cost in U.S. dollars.  However, this can be automatically converted into other currency units via the pull-down menu.

This function assumes that the pitch of the roof is the same on both sides.  For roofs of different pitches, one must estimate the cost of the rafters one each side individually, since they will be different.  It also assumes that a single rafter board will go from the edge of the roof to the roof's ridge (i.e. no scabbing boards together).

Unit Price

One should alway use local pricing for the unit price of a supply like lumber for rafter lumber.  However, for convenience, the following prices were observed on the Internet and presented for your convenience
