Truss Price Calculator
Truss price is usually quoted two ways: a flat price per truss, or a price per square foot of roof area. This calculator estimates both from your span, material, and truss spacing, so you can sanity-check a supplier quote before you buy.

What Drives the Price of a Single Truss?
Per-truss price scales mainly with span and depth — a wider span needs more lumber and stronger connector plates per truss, so price per truss rises faster than price per square foot as span increases.
Material choice shifts the baseline: SPF lumber trusses price lowest, Douglas Fir and engineered-wood trusses cost more per truss but often allow wider spans, and steel trusses carry the highest per-unit price but the lowest weight-to-strength ratio for very wide spans.
Price per square foot is often the more useful number for comparing quotes across different spacing options, since it normalizes for truss count — this calculator's cost breakdown shows both figures so you can compare fairly.
Frequently Asked Questions
How much does a single roof truss cost?
A single standard residential truss commonly costs $75-$250 depending on span, material, and complexity — wider spans, steeper pitches, and specialty types (scissor, attic) cost more per truss. Enter your specs above for an estimate.
Is it cheaper to price trusses per truss or per square foot?
Neither is inherently cheaper — they are two ways of expressing the same total cost. Per-square-foot pricing is more useful for comparing different spacing options on the same roof, since it accounts for truss count automatically.
