Construction Loan Cost Calculator
Explanation
How to calculate the cost of a construction loan?
A construction loan is a short-term loan used to finance the building of a home or other real estate project. The cost of a construction loan can be determined using the following formulas:
1. Monthly Payment Calculation:
The monthly payment can be calculated using the formula:
§§ M = \frac{P \times r}{1 - (1 + r)^{-n}} §§
where:
- § M § — monthly payment
- § P § — principal amount (loan amount minus down payment)
- § r § — monthly interest rate (annual interest rate divided by 12)
- § n § — total number of payments (loan term in months)
Example:
- Loan Amount (§ P §): $100,000
- Down Payment: $20,000
- Interest Rate: 5% (0.05)
- Loan Term: 30 years (360 months)
First, calculate the principal:
§§ P = 100,000 - 20,000 = 80,000 §§
Then, calculate the monthly interest rate:
§§ r = \frac{0.05}{12} = 0.004167 §§
Now, calculate the monthly payment:
§§ M = \frac{80,000 \times 0.004167}{1 - (1 + 0.004167)^{-360}} \approx 429.46 §§
2. Total Payment Calculation:
The total payment over the life of the loan can be calculated as:
§§ T = M \times n §§
where:
- § T § — total payment
- § M § — monthly payment
- § n § — total number of payments
Using the previous example:
§§ T = 429.46 \times 360 \approx 154,803.60 §§
3. Total Interest Calculation:
The total interest paid can be calculated as:
§§ I = T - P §§
where:
- § I § — total interest
- § T § — total payment
- § P § — principal amount
Using the previous example:
§§ I = 154,803.60 - 80,000 \approx 74,803.60 §§
