If you work in woodworking, construction, or carpentry, understanding how much you’re paying per board foot is essential for cost control and planning. A board foot is a unit of measurement for lumber volume that helps standardize pricing across different wood dimensions. Knowing the cost per board foot allows you to accurately budget for your material expenses, compare vendor prices, and manage your overall project costs.
Whether you’re building a deck, constructing furniture, or ordering wood in bulk, this calculator makes it easy to determine how much you’re actually paying per board foot.
Formula
The basic formula to calculate cost per board foot is:
Cost Per Board Foot = Total Cost ÷ Total Board Feet
Where:
- Total Cost is the price paid for all the wood.
- Total Board Feet is the total volume of lumber in board feet.
For example, if you spend $120 on 40 board feet of wood:
$120 ÷ 40 = $3.00 per board foot
How to Use the Cost Per Board Foot Calculator
The calculator above is simple and user-friendly. Here’s how to use it:
- Enter Total Cost ($): Input the amount you paid for your wood.
- Enter Total Board Feet: Input the board feet total, which can be calculated based on the wood’s dimensions (length × width × thickness ÷ 144).
- Click “Calculate”: The cost per board foot will be instantly displayed in dollars.
This calculator works for all types of wood including pine, oak, cedar, mahogany, and more.
Example Use Case
Let’s say you buy:
- 10 pieces of lumber, each measuring 8 ft long, 6 inches wide, and 2 inches thick.
- First, calculate board feet:
Each piece = (8 × 6 × 2) ÷ 144 = 0.6667 board feet
Total = 10 × 0.6667 = 6.667 board feet
If the total cost was $100:
- Cost per board foot = $100 ÷ 6.667 = $15.00 per board foot
Knowing this, you can compare vendors or calculate how many more pieces you can buy within your budget.

16. What’s the difference between nominal and actual dimensions?
Nominal dimensions are the “named” size (like 2×4), but actual sizes are smaller due to planing.
17. Can I use this calculator for MDF or plywood?
