Practical Example: Calculating Costs for 10 Windows

Suppose you want to install 10 double pane windows with the following specs:

• Average width: 36 inches
• Average height: 48 inches
• Material cost per square foot: $25
• Installation cost per window: $150
• Estimated annual energy savings per window: $75

How the Calculator Works with These Inputs:

• Calculate Window Area per Window:
  (36 in × 48 in) ÷ 144 = 12 sq.ft. per window
• Total Window Area:
  12 sq.ft. × 10 windows = 120 sq.ft.
• Material Cost:
  120 sq.ft. × $25 = $3,000
• Total Installation Cost:
  $150 × 10 = $1,500
• Total Project Cost:
  $3,000 + $1,500 = $4,500
• Average Cost per Window:
  $4,500 ÷ 10 = $450
• Estimated Annual Energy Savings:
  $75 × 10 = $750
• Payback Period:
  $4,500 ÷ $750 = 6 years

This calculation means you can expect to recover your investment in six years through energy savings, alongside enjoying the comfort and durability of double pane windows.
