Truss Cost Calculator

For standard residential wood trusses, plan on roughly $4–$11 per foot of span per truss in delivered material: a 24 ft Fink commonly lands between $120 and $260, while a 40 ft double-Howe runs $350 to $700. A full package for a 24 × 36 ft building at 24 in. o.c. — 19 trusses — typically totals $2,500 to $5,500 before labor. Every number on this page is a regional range reference, not a quote: your actual price comes from a manufacturer who has your span, pitch, load zone, and roof plan in hand.

A 24 ft truss is the most-quoted size in residential construction, which keeps its price competitive: $120–$260 each in most markets, with 2x4-chord Fink profiles at the low end and snow-zone 2x6 top chords toward the high end. At 24 in. spacing a 36 ft-long building needs 19 of them, so the truss line item alone is roughly $2,300–$4,900. Add delivery (often $150–$500 for one flatbed load) and, if you are not setting them by hand, crane time of $60–$150 per hour with a two-hour minimum.

Installation is usually quoted as part of a whole-roof framing package of $4–$8 per square foot of footprint, but standalone truss setting runs $2–$5 per square foot where the walls are ready and access is clean. A three-person crew sets 10–15 small trusses in a day by hand or 20+ with a boom; a 40 ft truss at 300+ lb is crane work, full stop. Marking layouts, temporary bracing, and permanent bracing are part of setting day — a bid that excludes bracing bundles and hardware is not a complete installation price.

Weight scales with span, chord size, and web count: 2x4-chord Finks run about 4 lb per foot of span (a 24 ft truss ≈ 100–140 lb), while 2x6-chord Howe and Pratt profiles beyond 28 ft run closer to 8 lb per foot (a 40 ft truss ≈ 300–450 lb). Weight is the silent cost driver: it decides whether two people can set each truss or a crane is mandatory, how many trips the flatbed makes, and whether the delivery site needs maneuvering room. The estimator above reports a weight per truss alongside the price range for exactly this reason.

Three legitimate reasons. First, scope: one bid may include engineering seals, bracing bundles, and hangers while another quotes bare trusses. Second, profile assumptions: a 6/12 Fink and a 6/12 Howe at the same span use different lumber volumes, and a bidder who assumes a different pitch than you meant will price a different truss. Third, region: species availability and mill competition move prices 20% or more between markets. Comparing two quotes line by line against your spec sheet — not just the bottom number — is where the savings hide.

No — and a website that pretended otherwise would be lying. The dashboard produces a range built from typical per-foot material pricing, regional factors, and complexity adders, sized for sanity-checking: if a quote arrives at half the low end, scope is probably missing; if it doubles the high end, either your market is genuinely expensive or the package includes work the range cannot see. The Copy spec sheet button turns your inputs into the RFQ text that gets you the number that actually counts.
