Cost per window calculator
Multiply your count by a per-window price for a quick project total, with labeled installed bands by type to sanity-check the figure.
At $650.00 a window, 10 windows is about $6,500.00. Installed vinyl double-hung windows run roughly $300–800 each; wood ~$800–2,000 — labeled bands, not a quote.
Calculator inputs
The simplest cost view: how many windows, times what each one costs. It is the right tool for a first-pass budget or for turning a lump-sum quote into an apples-to-apples per-window number you can compare against the labeled bands below. For the full picture — labor, add-ons, contingency — step up to the replacement cost calculator.
Formula
total = count × your $/window
Whether your per-window price is material-only or installed is up to you — just be consistent when you compare quotes.
Worked example
Ten windows at $650 each is $6,500. That $650 sits comfortably inside the vinyl double-hung band ($300–800) but below the wood band ($800–2,000), which tells you at a glance what class of window the price implies.
Reading the per-window price
A per-window price is the fastest lie-detector for a quote. Divide a lump sum by the opening count and you can immediately see whether the number lands in the vinyl band, the wood band, or somewhere that needs explaining. The contractor quote check does exactly this and flags it against the labeled band for the material.
Watch for scope hiding inside “per window.” A pocket insert and a full-frame replacement of the same window are different products at different prices; a picture window and a crank-out casement of the same size are too. Match like with like, and confirm the opening count on site — a bay or bow is one opening but several glass panels.
Reference table
| Window type | Typical installed $/window | Fit |
|---|---|---|
| Double-hung | $300–$800 | Two vertical sashes; the value default |
| Casement | $400–$1,000 | Crank-out; seals tight, opens fully for egress |
| Sliding | $350–$900 | Horizontal glider; value option |
| Awning | $400–$1,000 | Top-hinged; vents in rain |
| Picture | $300–$1,200 | Fixed; best U-factor, no ventilation |
| Bay / bow | $1,500–$4,500 | Projecting multi-panel unit |
