What will your windows actually cost?
Nine inputs, a per-window range, and the component prices behind it. Nothing is sent anywhere and nothing is gated.
Planning range for the United States, checked November 2026. Not a quote. Excludes structural repair, rot, masonry, lead abatement, siding, drywall and paint. The regional multiplier is a planning band, not a measured wage.
What the calculator is actually adding up
A window price is four things stacked: the unit, the labour to set it, the removal of the old one, and the weatherproofing and trim around the opening. Most calculators collapse those into one multiplier. This one does not, so you can see which line is driving your number.
| Component | Per window | Notes |
|---|---|---|
| Unit, vinyl double-hung, standard size | $200 – $430 | Material only, no install |
| Labour, insert into existing frame | $120 – $260 | Per opening, one crew |
| Labour, full-frame replacement | $230 – $480 | Per opening, plus trim |
| Removal and disposal | $25 – $55 | Per old window |
| Weatherproofing (foam, caulk, tape) | $15 – $40 | Insert; $35 – $85 full-frame |
| Interior and exterior trim | $40 – $110 | Per window, full-frame only |
| Permit | $0 – $350 | Flat, varies by jurisdiction |
The two markets, and why they differ by 2×
The same window opening can be bought two ways. You can buy the unit from a supplier and pay a local installer a day rate, or you can sign with a full-service replacement company that bundles the product, the crew, the warranty and the sales process into one price.
The installed difference between those two markets is consistently around double. That is not a markup on the same thing — the full-service side carries a longer labour warranty, its own crews, and a sales cost per job. But it does mean that a single "average cost" number is meaningless until you say which market it describes.
Worked examples
Ten standard vinyl double-hung inserts, national average labour, is the default the calculator opens on. Here is what changes when one variable moves.
| Project | Per window | Project total |
|---|---|---|
| 10 vinyl double-hung, insert, national | $360 – $785 | $3,600 – $7,850 |
| 10 vinyl double-hung, full-frame | $530 – $1,160 | $5,300 – $11,600 |
| 10 fiberglass double-hung, insert | $480 – $1,043 | $4,800 – $10,430 |
| 10 wood-clad double-hung, full-frame | $810 – $1,762 | $8,100 – $17,620 |
| 3 bay windows, insert | $1,745 – $4,980 | $5,235 – $14,940 |
| 10 impact, Low-E glass, South region | $910 – $1,966 | $9,096 – $19,664 |
What moves the number most
- Install method. Full-frame roughly doubles the labour line and adds trim. It is also the only option when the frame is rotted.
- Size. An oversized unit costs 1.7× a standard one before any upgrade, because glass and frame are priced by area.
- Frame material. Fiberglass runs about 1.6× vinyl; wood-clad about 2.4×.
- Glass package. Triple pane adds about 30% to the unit. Low-E with argon adds about 12% and is usually the better buy.
- Style. A bay or bow is its own project, not a window — it needs a structural opening and its own labour band.
- Market tier. The single largest swing on most jobs.
What the estimate does not cover
- Rot, structural damage or a failed header found after removal.
- Masonry, stucco or siding repair around the opening.
- Lead paint abatement on pre-1978 housing — a legal requirement, not an upgrade.
- Interior drywall and paint beyond the immediate trim line.
- Engineering, HOA approval or historic-district review.
- Financing interest. The cash price is what is shown.
How to use the number
Take the range, not the midpoint. If a bid lands inside it, the scope is probably in the normal band and the question becomes what is included. If a bid lands well below it, the scope is missing something — usually trim, disposal, permit or a proper flashing detail. If a bid lands well above it, ask which line is above the published band.
Our methodology page explains how the bands are checked, the cost hub carries the full price table by style, and the contractor hub covers how to read a quote line by line.
Frequently asked
Why is the range so wide?
Because two markets are being priced. Buying the window and hiring a local installer runs roughly half of what a full-service replacement company charges for the same opening. The market switch above the inputs applies that gap instead of hiding it in a single average.
Is this a quote?
No. It is a planning range built from the component prices we publish below. A quote depends on the exact unit, the opening condition, the trim, the permit and the installer. Use this to judge whether a bid is in the right neighbourhood.
Does the ZIP code change the price?
Only through the regional labour multiplier you select. We do not adjust the unit price by ZIP, because manufacturer pricing is national while installer pricing is local. The multiplier is a planning band, not a measured wage.
Why is full-frame so much more?
The old frame comes out, so the opening needs new flashing, insulation, exterior trim and often interior repair. That is roughly double the labour of an insert, plus 40 to 110 dollars a window in trim.
What is not included?
Structural repair, rot, masonry, lead paint abatement, exterior siding repair, interior drywall and paint, and any design or engineering fee. Anything the installer discovers after removal is an extra.
Where do the numbers come from?
Published 2026 installed-price bands, cross-checked against four independent cost guides and the component arithmetic shown on this page. Every figure is a planning band labelled with the month it was checked, not a manufacturer price list.
