Mortgage Calculation Formula Explained
The calculator uses a standard mortgage formula used by banks worldwide:
Monthly Payment Formula:
M=(1+r)n−1P×r×(1+r)n
Where:
- M = Monthly payment
- P = Loan principal (amount borrowed)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (years × 12)
Understanding the Formula in Simple Terms
- The loan amount is spread over the total number of months.
- Interest is added every month based on remaining balance.
- Early payments contain more interest and less principal.
- Over time, interest decreases and principal repayment increases.
This is known as an amortization system.
Example Calculation
Let’s understand with a real-life example:
Loan Details:
- Loan Amount: $200,000
- Annual Interest Rate: 6%
- Loan Term: 20 years
Step-by-Step Breakdown:
- Monthly interest rate = 6 ÷ 12 ÷ 100 = 0.005
- Number of months = 20 × 12 = 240
Results:
- Monthly Payment: $1,432.86
- Total Payment: $343,886.40
- Total Interest: $143,886.40
