Price Per Linear Foot Calculator

What Is a Price Per Linear Foot Calculator?

This calculator determines the cost per linear foot of any material or product. You provide the total price paid and the total length in feet, and the tool divides the cost by the length to give you a per-foot price. This is useful for comparing pricing across different lengths of lumber, trim, molding, piping, cable, fabric, or any material sold by the foot.

How to Calculate Price Per Linear Foot

The calculation is straightforward:

Price Per Linear Foot = Total Price ÷ Total Length (in feet)

For example, if you pay $45 for a 15-foot board, the price per linear foot is $45 ÷ 15 = $3.00 per foot.

This formula works for any material where the total cost and total length are known. The result gives you a standardized unit price that makes it easy to compare costs between different suppliers or different lengths of the same material.

How to Use the Calculator

1. Enter the total price — the amount you paid or the listed price for the item.
2. Enter the total length — the length of the material in feet.
3. Click calculate — the tool instantly shows the price per linear foot.

You can adjust either value to see how changes in price or length affect the per-foot cost.

Practical Use Cases

• Lumber and building materials — Compare pricing on dimensional lumber, decking, trim, and molding from different suppliers.
• Pipes and conduit — Evaluate cost differences between PVC, copper, or steel pipes sold by the foot.
• Cable and wiring — Determine the per-foot cost of electrical wire, coaxial cable, or networking cable.
• Fabric and textiles — Compare fabric prices when buying by the yard or by the foot.
• Fencing and railing — Calculate the cost per foot for fencing materials to estimate project budgets.

Understanding Your Results

The result is a simple dollar amount per linear foot. A lower price per foot generally indicates better value, but consider material quality, thickness, and grade when comparing. For example, a cheaper per-foot price on lower-grade lumber may not be a better deal if you need higher-grade material for structural applications.

Note that this calculator assumes the total price covers the entire length. If there are additional fees (delivery, cutting charges, or waste factors), those should be included in the total price for an accurate per-foot comparison.

Common Mistakes to Avoid

• Mixing units — Ensure the length is entered in feet. If you have inches, convert to feet first (divide inches by 12).
• Forgetting additional costs — If you're comparing suppliers, include delivery fees or minimum order charges in the total price.
• Ignoring material grade — A lower price per foot may reflect lower quality. Always compare like-for-like materials.
• Confusing linear feet with square feet — This calculator measures length only, not area. For materials sold by area (like plywood), use a price per square foot calculator instead.

Limitations

This calculator provides a simple division based on the numbers you enter. It does not account for volume discounts, bulk pricing tiers, or material waste. For accurate project budgeting, consider adding a waste factor (typically 10–15% for lumber and similar materials) to your total length before calculating.
