What is a Window Replacement Cost Calculator?
A Window Replacement Cost Calculator estimates the total cost of replacing windows in your home, including materials, labor, permits, and additional services. Window replacement is a significant home improvement project that can improve energy efficiency, increase property value, and enhance comfort.
This calculator considers window type, frame material, energy efficiency ratings, installation complexity, and regional cost variations to provide accurate cost estimates. Professional window replacement typically costs $300-$1,200 per window, depending on materials and installation requirements.
Window Replacement Cost Calculation Formulas
Window replacement costs are calculated based on material costs, labor rates, and additional services required for proper installation.
Basic Cost Formula
Total Cost = (Material Cost + Labor Cost) × Number of Windows + Additional Services Cost Per Window = Material Cost + Labor Cost + (Additional Services ÷ Number of Windows)
Energy Efficiency Upgrade Cost
Energy Upgrade Cost = Base Cost × Energy Efficiency Multiplier Annual Energy Savings = Improved Efficiency × Energy Cost × Usage Hours Payback Period = Upgrade Cost ÷ Annual Energy Savings
Example: 10 double-hung windows with vinyl frames:
Material cost: $300 × 10 = $3,000
Labor cost: $200 × 10 = $2,000
Permits: $150
Total project cost: $5,150 ($515 per window)
How to Calculate Window Replacement Costs
Cost Factors by Window Type
Single-Hung Windows

- Best for: Budget-conscious projects, traditional homes
- Energy efficiency: Moderate sealing capability
Double-Hung Windows
- Material cost: $200-$600 per window
- Labor cost: $150-$350 per window
- Best for: Easy cleaning, versatile ventilation
- Energy efficiency: Good sealing with quality frames
Casement Windows
- Material cost: $300-$800 per window
- Labor cost: $200-$400 per window
- Best for: Maximum ventilation, modern designs
- Energy efficiency: Excellent sealing when closed
Common Window Replacement Applications
- Energy Efficiency Upgrade: Replace old windows to reduce heating and cooling costs with modern energy-efficient models
- Home Value Improvement: Window replacement can recoup 65-75% of investment in home resale value
- Maintenance Reduction: Replace high-maintenance wood windows with low-maintenance vinyl or aluminum
- Noise Reduction: Upgrade to double or triple-pane windows for better sound insulation
- Security Enhancement: Install windows with better locking mechanisms and impact-resistant glass
Frequently Asked Questions
How much does window replacement cost per window?
