Window Replacement Cost Calculator
Pick your city, the type of window or door, and how many. The estimate uses the same cost model behind our local guides for 319 metros, adjusted to your area's price level.
Short answer
Nationally, a standard-size vinyl double-hung window costs about $700–$1,520 installed, and eight of them run about $4,760–$10,335. Fiberglass costs roughly 28–45% more than vinyl, and wood more again. Local price levels run from about 16% below the U.S. average in Monroe, LA to 16% above it in San Francisco, CA.

How the estimate works
Each price starts from the federal NREL Remodeling Database, which prices vinyl windows per square foot. We bring those 2023 figures to June 2026 with the BLS Producer Price Index for windows and doors. Bay and bow windows, specialty shapes and all three door types don't scale with glass area, so they use market ranges escalated the same way.
Frame material is a multiplier on the vinyl price: about 28–45% more for fiberglass and 60–130% more for wood with a clad exterior. Then the whole figure shifts to your metro's price level using the Bureau of Economic Analysis Regional Price Parity (2024). That's a public index, so the local adjustment is the same one anyone could look up.
Full details, including every assumption, are on how we estimate local costs.
What a calculator can't see
Size matters most. The model prices a standard opening, for example 15 square feet for a double-hung (about 3 by 5 feet). A picture window twice that size costs roughly twice as much.
Install type is next. An insert fits a new window into the old frame and costs less; a full-frame job removes everything down to the rough opening, which is the right call when the frame is rotted. Who sells the job also matters. A national brand with in-home sales and its own crews prices higher than a regional installer, and the top of each range is there to cover that.
A few costs only show up once someone looks at the house: rotted sills, structural work, lead-safe practices that federal rules require in homes built before 1978, and custom interior trim.
Window replacement cost calculator: FAQ
›How accurate is this window cost calculator?
It gives a planning range, not a quote. Base costs come from the federal NREL Remodeling Database, brought to June 2026 prices with the BLS Producer Price Index and adjusted to your metro with BEA Regional Price Parity. Real quotes move with window size, install type and brand, so get two or three before you decide.
›Does the number of windows change the price per window?
Yes. Setup, travel and disposal spread across a bigger job, so from 8 windows up the calculator applies a 15% discount per window. Smaller orders are priced at the full per-window rate.
›Why are some quotes far above these numbers?
Full-service national brands bundle in-home sales, premium frames, full-frame installation and their own crews, and they price accordingly. The top of each range is meant to cover that kind of job. A quote well past the top end deserves a line-by-line explanation.
›What is not included in the estimate?
The ranges cover a standard replacement, installed. Rotted framing, structural changes, lead-safe work practices in homes built before 1978, custom interior trim and permit fees can all add to the bill.
›What if my city isn't listed?
Pick the nearest listed metro or use the national average. The local adjustment follows regional price levels, so a nearby metro in the same state is usually a close match.
