Whole-house cost by window count
Because most homeowners replace multiple windows at once, the project total matters more than the per-unit price. Bob Vila estimates 5 windows at $1,000 to $5,750, 10 windows at $2,000 to $11,500, and 20 windows at $4,000 to $23,000.

- Installation: Bob Vila puts labor at $100 to $300 per window ($55 to $65 per hour); full-frame replacements with rot repair or resizing cost more than insert installs.
