Mortgage Calculation Formula Explained
The calculator uses the standard mortgage formula:
M=P⋅(1+r)n−1r(1+r)n
Where:
- M = Monthly payment
- P = Loan principal ($189,000)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of payments (years × 12)
Breaking Down the Formula
- The formula accounts for compound interest, meaning interest is calculated on both the principal and accumulated interest.
- Monthly payments remain fixed throughout the loan term.
- Early payments mostly cover interest, while later payments reduce the principal.
Example Calculation
Let’s look at a real-life scenario:

| Metric | Value |

| Monthly Payment | $1,133.00 |
| Total Interest Paid | $218,000+ |
| Total Cost | $407,000+ |
Explanation:
- You pay around $1,133 per month
- Over 30 years, interest nearly exceeds the original loan
- Total repayment becomes more than double the principal
