Worked example: 5 double-hung windows, 2 of them upstairs
The calculator above starts on a common partial job: three failed double-hung windows on the ground floor and two upstairs, in vinyl with double-pane Low-E glass, insert installation and an average-cost region. It returns $2,350 – $4,950, typical $3,550 for 5 windows (average $710 per window).
| Group | Per window | Group typical |
|---|---|---|
| 3 × Double-hung | $450 – $950 | $2,050 |
| 2 × Double-hung (upper floor) | $500 – $1,060 | $1,500 |
The two upstairs windows carry the model's 12% upper-floor factor, which is why their per-window range is higher than the ground-floor row. Open this example in the whole-house calculator.
What changes the total on a small job
With only five openings, a single choice moves the total noticeably. Same five windows, one input changed:
| Change | Calculator output | Typical |
|---|---|---|
| As above (insert, Low-E) | $2,350 – $4,950 | $3,550 |
| Full-frame instead of insert | $2,950 – $6,250 | $4,400 |
| Plain double-pane instead of Low-E | $2,150 – $4,500 | $3,200 |
Partial jobs are often triggered by rot or leaks around the frame. If that's why you're replacing these windows, price them as full-frame: an insert sits inside the old frame and can't fix the opening around it. The full-frame vs. insert calculator shows the gap for any style.
Choosing which windows go first
- Failed or leaking units. Fogged glass between panes (a failed seal), water stains under the sill, or sashes that won't stay open or lock.
- Soft or rotted frames. These usually need full-frame work, so price them separately from sound openings.
- Safety and access. Bedroom windows that won't open fully, and upper-floor windows that can't be cleaned safely.
- Worst exposure. Windows on the side of the house that takes the most sun or weather.
Why a small job can quote above the range
This calculator is linear: five windows cost exactly half of ten identical ones, with no minimum job charge. Installers don't always work that way. Angi recommends replacing no fewer than five to eight windows per job, because crews often bid a flat rate and their overhead is the same for a short job (Angi, October 15, 2026). So on a five-window job, a quote somewhat above the range isn't automatically a red flag. Ask how the price would change if you added the next few windows on your list; the methodology limitations explain what the model leaves out.
One window on its own, in the same specification, comes to $450 – $950 in the main calculator.

Frequently asked questions
How much does it cost to replace 5 windows?
In this calculator, 5 vinyl double-hung windows with Low-E glass and insert installation, 2 of them upstairs, come to $2,350–$4,950, typical $3,550. Full-frame installation raises that to $2,950–$6,250. Use the calculator above to change the style, frame or floor of each window.
Is it worth replacing only a few windows?
Yes, when only a few have failed or the budget won't stretch. Keep the same product line so later phases match. Expect a higher price per window than on a whole-house job, since Angi notes installers' overhead is the same on short jobs.
Does the calculator add a minimum charge for small jobs?
No. The model prices each window the same whether you replace 1 or 60, so small jobs can quote above its range. This is listed in the methodology limitations.
