The **Cost of Floor Joists** calculator computes the cost of lumber based on the unit price and the number of joists required for a floor based on the dimension of the room.

**INSTRUCTIONS: **Choose your preferred units and enter the following:

**(W)**Width of Floor across joists**(L)**Length of Floor parallel to the joists**(oC)**On-center- (
**uP**) Unit Price of a floor Joist board

**TOTAL PRICE: **The calculator computes the number of floor joist boards needed and applies the unit price to compute a total cost in U.S. dollars. However, this can be automatically converted into other currency units (e.g. Pesos) via the pull-down menu.

**ASSUMPTIONS:** this algorithm assumes that the following:

- the length of the area is less than or equal to the length of one joist. For spans greater than the length of one joist, a beam is often required and a second row of joists. This would double the number and cost of joists.
- the plate boards are approximately the same size as the joists.

One should always use local pricing for the unit price of a supply like lumber for rafter lumber. However, for convenience, the following prices of 2x6s, 2x8s, 2x10s and 2x12s were observed on the Internet and presented for your convenience

The 2x6 Lumber Pricing table contains recent lumber prices for 2x6 of a variety of lengths with prices from Lowes, Home Depot, Menards and potentially other stores based on their web sites.

This table is a repository of pricing data for common lumber (2x6's) as surveyed from the websites of major lumber retailers in the United States.

**2x6 Price Survey Date**: 4/10/24**2x6 Price Survey Store**: Menards**2x6 Price by Length****Price of an 8' 2x6**: $6.98**Price of a 10' 2x6**: $10.53**Price of a 12' 2x6**: $11.52**Price of a 16' 2x6**: $14.62

All prices are in U.S. dollars and based on searches of nationally advertised prices from the provider's web sites. Search string: "kiln dried 2x6 lumber" is used in the retailer's website. The term two by six (2x6) refers to the rough cut dimensions of construction grade lumber. However, the typical 2x6 purchased at a lumber yard is actually `1 3/4`" x `5 1/2`". Nonetheless, the term 2x6 persists. These values can be used in the **Stud Framing Calculator ** and the Joist Framing Calculator.
