Formula Used in Carpet Calculation
This calculator uses a simple mathematical approach:
1. Area of Room
Area = Length × Width
2. Total Carpet Cost
Total Cost = Area × Price per sq ft
Example Formula Breakdown:
If:
- Length = 15 ft
- Width = 12 ft
- Price per sq ft = $4
Then:
Area = 15 × 12 = 180 sq ft
Total Cost = 180 × 4 = $720

| Length (ft) | Width (ft) | Area (sq ft) | Price per sq ft ($) | Total Cost ($) |
|---|---|---|---|---|
| 10 | 10 | 100 | 3 | 300 |
| 12 | 10 | 120 | 4 | 480 |
| 15 | 12 | 180 | 5 | 900 |
| 20 | 15 | 300 | 6 | 1800 |
