Window Replacement Cost Calculator: what to expect
Window replacement is priced per opening, and the spread comes from frame material, glass package, and whether it's a retrofit (insert) or full-frame replacement. Larger and custom shapes carry a premium.
Across the United States, a window replacement cost averages $10,184 once mid-range materials, licensed labor, and standard permits are included. The figures below are a national baseline; pick your state or city to apply local labor rates, material delivery costs, and permit fees.

- Look for ENERGY STAR rebates and utility incentives.
How this estimate is calculated
We start from a base cost-per-opening for window replacement cost and adjust it for finish quality, labor complexity, waste, and equipment, then apply national baseline indices. The figures update with the cost data and reflect mid-range, licensed-contractor pricing, not a binding quote.
