Turn a window count and style into a planning range for installed cost.
Use this estimator to build a planning range before you call contractors. Enter how many windows you plan to replace, pick a window type to load an illustrative per-window range, and adjust the low and high figures to match what local bids suggest. The Extras field covers costs that are not tied to a single window, such as permits, debris disposal, interior trim work, or lead-safe work practices in a pre-1978 home.
The math is simple: low estimate = windows x low cost per window + extras, and high estimate = windows x high cost per window + extras. For example, 10 windows at $500 to $1,100 each plus $400 in extras gives a range of $5,400 to $11,400. Those figures are illustrative defaults, not quotes or current market prices.
Limits: the tool does not know your region, the size of each opening, whether you need full-frame work, or whether rot is hiding behind the trim. Large, custom-shaped, egress or tempered-glass units usually cost more than the base range. Treat the result as a way to spot a bid that is far outside the range and ask why, then collect at least three written bids to find your real number.
