Formula Used in House Cost Calculation
The calculator follows a structured financial formula used in real construction budgeting.
1. Base Construction Cost
Base Cost = Area × Rate per sq ft
2. Additional Costs
Additional Costs = Material + Labor + Permit
3. Subtotal
Subtotal = Base Cost + Additional Costs
4. Contingency Amount
Contingency = Subtotal × (Contingency % ÷ 100)
5. Total Estimated Cost
Total Cost = Subtotal + Contingency
Example Calculation:
If:
- Area = 1200 sq ft
- Rate = $40 per sq ft
- Material = $10,000
- Labor = $8,000
- Permit = $2,000
- Contingency = 10%
Then:
Base Cost = 1200 × 40 = $48,000
Additional Costs = 10,000 + 8,000 + 2,000 = $20,000
Subtotal = $68,000
Contingency = $6,800
Total Cost = $74,800
House Construction Cost Example Table
| Area (sq ft) | Rate ($/sq ft) | Material ($) | Labor ($) | Permit ($) | Contingency (%) | Total Cost ($) |
|---|---|---|---|---|---|---|
| 1000 | 35 | 8,000 | 5,000 | 2,000 | 10% | 59,500 |
| 1200 | 40 | 10,000 | 8,000 | 2,000 | 10% | 74,800 |
| 1500 | 45 | 12,000 | 10,000 | 3,000 | 12% | 103,040 |
| 1800 | 50 | 15,000 | 12,000 | 3,500 | 15% | 129,025 |
| 2000 | 55 | 18,000 | 15,000 | 4,000 | 10% | 159,500 |
