Window Replacement Cost Calculator
Your windows
Example: 10 vinyl double-hung windows at the midpoint of $625 each cost $6,250 installed, with a typical range of $4,500 to $8,000.
Behind the numbers
How window replacement cost is calculated
Prices are typical installed prices in the US in 2026 — the window plus standard installation labor. Start with the price of a double-hung window in your chosen material, apply the multiplier for your window type, then multiply by the number of windows.
10 windows × $625 (vinyl double-hung midpoint) × 1.00 = $6,250. The low end uses $450 per window ($4,500) and the high end uses $800 per window ($8,000).
Typical installed price per double-hung window, US 2026
Type multipliers: double-hung 1.00, casement 1.10, sliding 0.90, bay 2.20, picture 1.50. Bay and picture windows cost more because they are larger and more complex to install; sliding windows cost a little less than double-hung.
A few comparisons
Example window replacement costs
| Windows | Type & material | Per window | Estimated total | Range |
|---|---|---|---|---|
| 10 | Vinyl double-hung | $625 | $6,250 | $4,500 – $8,000 |
| 10 | Wood casement | $1,265 | $12,650 | $8,800 – $16,500 |
| 6 | Fiberglass sliding | $855 | $5,130 | $3,780 – $6,480 |
| 4 | Aluminium bay | $1,210 | $4,840 | $3,520 – $6,160 |
| 8 | Vinyl picture | $938 | $7,500 | $5,400 – $9,600 |
Per-window figures are midpoints, rounded to the nearest dollar; totals use the unrounded midpoint. This is an estimate — actual quotes vary by region, installer and glazing options.
Small changes. Lower window bill.
Replacing several windows at once usually costs less per window than one at a time, because the installer makes fewer trips.
Vinyl is the cheapest material and needs almost no maintenance; wood looks warmer but costs more and needs regular painting or sealing.
Get at least two or three local quotes for the same window type and material — prices for the same job can differ by hundreds of dollars per window.
Ask whether the quote includes removing the old windows, new trim and disposal; a low quote sometimes leaves those out.
Good to know
Your window cost questions, answered.
How much does it cost to replace one window?
A typical installed vinyl double-hung window costs $450 to $800 in the US in 2026. Wood runs $800 to $1,500, fiberglass $700 to $1,200 and aluminium $400 to $700. Bay and picture windows cost more because they are larger and more complex to install.
Does the window type change the price?
Yes. This calculator starts from the price of a double-hung window in your chosen material, then applies a multiplier: casement 1.10, sliding 0.90, bay 2.20 and picture 1.50. A sliding window costs a little less than a double-hung, while a bay window costs more than twice as much.
Are these prices installed or just the window?
The prices on this page are installed prices — the window plus standard installation labor. They do not include structural repairs, new trim, custom sizes or premium glazing options, which can add to the final quote.
Why do actual quotes vary so much?
Quotes vary by region, installer, window size, glazing options such as double or triple pane, and the condition of the existing frames. Always get at least two or three local quotes before you commit.
