Mortgage Calculation Formula Explained
This calculator uses the standard amortization formula used worldwide for mortgage loans.
Monthly Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan amount (principal)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of months (years × 12)
What This Formula Means
- The loan is divided into equal monthly payments
- Early payments contain more interest and less principal
- Over time, interest portion decreases and principal increases
This method ensures the loan is fully paid off by the end of the term.
Example Calculation
Let’s understand with a real-life example:
Loan Details:
- Loan Amount: $100,000
- Interest Rate: 6% per year
- Loan Term: 20 years
Step-by-step:
- Monthly interest rate = 6 ÷ 12 ÷ 100 = 0.005
- Total months = 20 × 12 = 240
Results:
- Monthly Payment: ≈ $716.43
- Total Payment: ≈ $171,943
- Total Interest: ≈ $71,943
This shows how interest significantly increases total repayment over time.
