Interior Door Installation cost
Carpentry ranges track material grade and fitment surprises once trim or openings are open. For Interior Door Installation we use mid hours of 2.5 and materials around $160, then apply the same 2.0× / 2.25× / 2.5× labor markup schedule as every other Fairange job.

How the national mid is built
Before you enter a ZIP we use the U.S. OEWS mean wage for Carpenters (SOC 47-2031): $31.55/hr (BLS OEWS May 2025). Mid estimate ≈ 2.5 hours × $31.55 × 2.25× markup + materials mid $160 (with a small regional materials factor). Low uses p10 wages × 2.0×; high uses p90 × 2.5×. National planning band: $138 – $337 – $830.
Full algebra: methodology. Markup schedule is Fairange’s published assumption, not a BLS figure.
Materials band
Published materials low / mid / high: $80 / $160 / $350 (prehung hollow-core or solid-core interior door, standard opening). Baselines are Fairange editorial figures tied to public retail when we have a SKU basket; full source notes live in DATA_SOURCES and the methodology page. We dampen materials with a regional factor (about 0.88–1.18) so wages — not a fake local parts market — do most of the geography.
