Formula Used by the Window Cost Calculator
The calculator follows a straightforward cost estimation process.
1. Material Cost Formula
Material Cost = Number of Windows × Cost Per Window
Example
If:
- Number of Windows = 10
- Cost Per Window = $400
Then:
Material Cost = 10 × 400
Material Cost = $4,000
2. Subtotal Formula
Subtotal = Material Cost + Installation Cost + Additional Expenses
Example
If:
- Material Cost = $4,000
- Installation Cost = $1,200
- Additional Expenses = $300
Then:
Subtotal = 4,000 + 1,200 + 300
Subtotal = $5,500
3. Sales Tax Formula
Sales Tax Amount = Subtotal × (Tax Rate ÷ 100)
Example
If:
- Subtotal = $5,500
- Tax Rate = 8%
Then:
Sales Tax = 5,500 × 0.08
Sales Tax = $440
4. Total Window Project Cost Formula
Total Cost = Subtotal + Sales Tax
Example
Total Cost = 5,500 + 440
Total Cost = $5,940
Complete Example Calculation
Suppose you are replacing windows throughout your home.
Project Details
| Item | Value |
|---|---|
| Number of Windows | 12 |
| Cost Per Window | $450 |
| Installation Cost | $1,800 |
| Additional Expenses | $400 |
| Sales Tax | 7% |
Step 1: Material Cost
12 × $450 = $5,400
Step 2: Subtotal
$5,400 + $1,800 + $400 = $7,600
Step 3: Tax
$7,600 × 7% = $532
Step 4: Total Cost
$7,600 + $532 = $8,132
Estimated Total Project Cost = $8,132
