What current 2026 data says
Modernize reports a 2026 national average of $1,047 per replacement window, with a typical installed range of $700–$1,400. Angi reports a broader individual-window range of $300–$2,500 and a project average of $7,348. The gap is useful: replacement pricing varies sharply by project scope and specifications.
- ✓Treat national averages as planning benchmarks, not quotes.
- ✓Compare at least two current datasets before publishing a single number.
- ✓Keep material, style, glass and installation complexity separate in your budget.
Why your quote can move
Window type, frame material, size, glass package, full-frame work, access, trim repair, permitting and local labor can all change the installed cost. Premium bay/bow assemblies and structural work can move far beyond a standard double-hung replacement.
Use the numbers
Turn benchmarks into a project range
Change window count, frame material, style and location in the estimator. It returns a planning range and shows the assumptions instead of hiding them.
