Formula Used in Home Loan Calculation
This calculator uses the standard mortgage amortization formula, which is widely used in banking and financial institutions.
1. Loan Principal
Loan Principal = Home Price − Down Payment
This is the actual amount borrowed from the lender.
2. Monthly Interest Rate
Monthly Rate = Annual Interest Rate ÷ 100 ÷ 12
This converts yearly interest into a monthly rate.
3. Monthly Mortgage Payment Formula
M=(1+r)n−1P⋅r⋅(1+r)n
Where:
- M = Monthly payment
- P = Loan principal
- r = Monthly interest rate
- n = Total number of months
4. Total Payment
Total Payment = Monthly Payment × Number of Months
5. Total Interest
Total Interest = Total Payment − Loan Principal
Example Calculation
Let’s understand with a real-world example:
- Home Price: $800,000
- Down Payment: $160,000
- Interest Rate: 6%
- Loan Term: 30 years
Step 1: Loan Principal
800,000 − 160,000 = $640,000
Step 2: Monthly Payment Calculation
Using the mortgage formula, the monthly payment comes out to approximately:
➡ $3,838.00 per month
Step 3: Total Payment
3,838 × 360 months = $1,381,680
Step 4: Total Interest
1,381,680 − 640,000 = $741,680
This shows how much interest significantly increases the total cost of a home loan.
