Roof Truss Cost Calculator
A standard residential roof truss costs roughly $75-$450 depending on span and material, with total project cost driven by material, labor, and installation together. Enter your span, pitch, spacing, and material choice below and this calculator returns a live material, labor, and installation breakdown for your project.

How to Estimate the Cost of Roof Trusses
Roof truss cost has three main components: material (lumber or steel, priced by board footage or member weight), labor (framing crew time to set and brace each truss), and installation extras like cranes for large spans or wide buildings.
Material choice has the biggest effect on price — SPF lumber is the cheapest option, Douglas Fir and engineered wood trusses cost more per board foot but can span further, and steel trusses carry the highest material cost but the lowest weight-to-strength ratio for very wide spans.
Truss spacing also changes total cost: 24" on-center spacing uses fewer, larger trusses, while 16" or 12" spacing uses more, often smaller trusses — the calculator's cost breakdown updates automatically as you change spacing so you can compare options.
Typical U.S. price-per-truss ranges (standard Fink truss, 2026 market rates):
| Span | Typical Price per Truss |
|---|---|
| 20-24 ft | $100-$180 |
| 26-30 ft | $150-$250 |
| 32-36 ft | $250-$350 |
| 38-40 ft | $350-$450 |
These are general market ranges for planning only — see the Truss Price Calculator for a per-truss and per-square-foot estimate based on your own inputs, and always confirm current pricing with a local supplier.
Frequently Asked Questions
How is the roof truss cost calculated?
This calculator multiplies your estimated board footage by a per-board-foot material rate, then adds labor and installation costs based on total roof area — giving a live material, labor, and installation breakdown as you adjust your inputs.
