How is Interest Calculated on a Home Loan?

Interest on a home loan is calculated daily and billed monthly on your remaining loan balance. This means that each month, you pay interest only on the outstanding amount. As you make payments, your loan balance decreases, which in turn reduces the interest you pay over time.

Example Calculation

Let’s consider a $600,000 home loan with a 6.00% interest rate over 30 years:

1. Convert the Interest Rate: Change the interest rate to a decimal: 6.00% / 100 = 0.0600.
2. Calculate Annual Interest: Multiply the loan amount by the decimal: $600,000 x 0.0600 = $36,000.
3. Determine Daily Interest: Divide the annual interest by 365 days: $36,000 / 365 = $98.63.
4. Compute Monthly Interest: Multiply the daily interest by the number of days in a month (e.g., 31 days): $98.63 x 31 = $3,057.53.

Your monthly interest cost would be approximately $3,057.53.

How Are Regular Mortgage Repayments Calculated?

Regular mortgage repayments are determined by the loan amount, interest rate, any applicable fees, and the loan term. The repayment amount is calculated by distributing the total loan balance—both principal and interest—over the loan term. Each lender may use a slightly different method for this calculation. The frequency of your payments (monthly, fortnightly, or weekly) is also considered and adjusted accordingly.
