Mortgage Payment
What Is an Amortized Mortgage?
An amortized mortgage is a type of loan where you pay both principal and interest through regular monthly payments over the life of the loan. Early in the mortgage, a higher portion of the payment goes toward interest, while over time, more of the payment reduces the principal balance.
This structure ensures that the mortgage is fully paid off by the end of the term, making it easier to budget for monthly payments and plan long-term finances.
How the Amortized Mortgage Calculator Works
The calculator uses the standard amortization formula:M=P(1+r)n−1r(1+r)n
Where:
- M = Monthly Payment
- P = Loan Amount (Principal)
- r = Monthly Interest Rate (Annual Rate ÷ 12 ÷ 100)
- n = Total Number of Payments (Years × 12)
If the interest rate is 0%, the calculator divides the principal evenly across the months. Otherwise, it calculates the compound interest to determine the monthly amount accurately.

Example Calculation
Suppose you borrow:
- Loan Amount: $350,000
- Annual Interest Rate: 4%
- Term: 30 years
Monthly Payment Calculation:M=350,000(1+0.003333)360−10.003333(1+0.003333)360
Resulting in a monthly payment of $1,671.57.
This figure includes both principal and interest, ensuring the loan is fully paid off at the end of the term.

Tips for Mortgage Planning

- Lock Interest Rates: Secure rates early to protect against market fluctuations.
- Account for Taxes and Insurance: Include property taxes and homeowner’s insurance in your budget.
Understanding Amortization Schedules
An amortization schedule shows how each monthly payment is split between principal and interest. Early payments mostly cover interest, while later payments reduce the principal more significantly.
| Payment # | Principal Paid | Interest Paid | Remaining Balance |
|---|---|---|---|
| 1 | $521.43 | $1,150.00 | $349,478.57 |
| 60 | $602.00 | $1,069.43 | $318,500.00 |
| 360 | $1,659.57 | $12.00 | $0 |
Understanding this can help you plan for early repayment or refinancing.
