How this estimate is calculated

Based on BLS, FRED & EIA data

Labor, weatherproofing and price escalation come from federal data. The base material cost does not — and we say so below rather than rounding it into the same sentence. Reference window: standard vinyl double-hung, retrofit install.

Labor: 2 man-hrs (NREL/Craftsman) × $29/hr national carpenter wage (BLS OEWS, SOC 47-2031) × 2.84 contractor markup = $165
Materials: Vinyl frame + Low-E glass, escalated 4.9% since 2025 by the FRED producer price index. The base cost this escalates is not independently sourced — it is the largest single term in the estimate and the one we cannot yet cite. Retail listings for the products named in our tiers put a comparable unit at $284–$379, which brackets it. How we are trying to close that.
Weatherproofing: $20–$35 per opening — flashing tape, foam, backer rod and caulk, priced per opening rather than as a percentage of the window (DuPont GREAT STUFF)
Installed cost: $509–$1,600 per window installed — the low end is buying the window and hiring an installer, the high end is a full-service replacement company. Both are installed prices; they are different markets, roughly 2× apart. · $5,090–$16,000 for a 10-window project (before bulk discount)

What drives your number

Most homeowners pay $509 to $1,600 per window installed in 2026, around $749 at the midpoint; a whole house of 10 to 15 windows runs $5,090 to $24,000. The calculator above prices your own count, types, frame, glass, install method and zip. Six things move it:

Window type. A double-hung insert is $509 – $1,013; a bay window is $2,162 – $5,832 and is quoted separately. Cost by window type
Frame material. Vinyl is the value leader; fiberglass and wood cost more and last longer. Cost by frame material
Glass package. Double-pane Low-E with argon is the sweet spot; triple-pane pays back in cold climates. Cost by glass
Labor and install method. $124 – $207 per standard window on an insert; full-frame adds 40–67% in labor. Installation and labor costs
Where you live. Labor rates, codes and climate move the same window 30–50% between metros — enter your zip above, or pick your state below.
How many at once. Ten or more windows earns volume pricing. Cost by number of windows

The full guide — every table, the energy and tax-credit picture, ROI and how to save — is at how much does window replacement cost in 2026. Every figure on both pages comes from the same model: BLS carpenter wages, FRED material indexes and NREL install-time benchmarks — see the methodology.
