Understanding Mortgage Amortization

Mortgage amortization is the process of paying off a home loan over time through regular monthly payments. Each payment includes a portion for the loan principal and interest. Over time, the interest component decreases, and the principal portion increases, ensuring that the loan is paid off in full by the end of the term.

Mortgage Amortization Formula

\[ M = P \cdot \frac{r(1 + r)^n}{(1 + r)^n - 1} \]

Where:

  • M = Monthly payment
  • P = Loan principal (amount borrowed)
  • r = Monthly interest rate (annual rate divided by 12)
  • n = Total number of payments (loan term in years multiplied by 12)

FAQs

What is a down payment?

A down payment is the upfront amount you pay when purchasing a home, expressed as a percentage of the home price. It reduces the loan amount.

What is included in the monthly payment?

The monthly payment includes principal and interest. If property taxes and insurance are entered, these costs are also included.

Why is amortization important?

Amortization helps you understand how your payments reduce your loan balance over time and how much interest you will pay during the loan term.

Can I pay off my mortgage early?

Yes, paying extra towards the principal can reduce the total interest and shorten the loan term. Check with your lender for prepayment penalties.
