Mortgage Repayment Calculator

Why Use a Mortgage Repayment Calculator?

A mortgage repayment calculator is an essential tool for anyone planning to take out a home loan or refinance an existing one. It helps you estimate your monthly, fortnightly, or weekly repayments based on your loan amount, interest rate, and loan term. For example, if you’re considering a $500,000 loan over 30 years with an interest rate of 5.5%, the calculator can show you how much you’ll pay monthly and the total interest over the life of the loan. This insight allows you to compare loan options and make informed financial decisions.

How Does a Mortgage Repayment Calculator Work?

A mortgage repayment calculator simplifies complex loan calculations into easy-to-understand results. By entering key details such as the loan amount, interest rate, repayment type (Principal & Interest or Interest-Only), and repayment frequency, the calculator estimates your repayments and provides an amortisation schedule. This schedule details how your repayments are allocated between the principal and interest over time. For instance, with a 30-year $400,000 loan at 6% interest, you can see how early payments are interest-heavy while later payments contribute more to reducing the principal.

What is the Amortisation Schedule for My Loan?

An amortisation schedule is a breakdown of each repayment throughout your loan term, showing how much goes toward interest and how much reduces the principal. This table or graph helps visualize your progress in paying off the loan. For example, with a $300,000 loan at 4% interest over 25 years, the schedule reveals that in the early years, a larger portion of your repayment goes toward interest. Over time, this shifts, and more of your payment is applied to reducing the principal balance.

Principal & Interest Repayments Versus Interest-Only Repayments

Understanding the difference between Principal & Interest (P&I) and Interest-Only (IO) repayments is crucial when choosing a loan. P&I repayments include both the loan’s principal and the interest, ensuring you gradually reduce the loan balance over time. In contrast, IO repayments only cover the interest for a specified period (e.g., 5 years), meaning the principal remains unchanged during that time. For instance, on a $400,000 loan at 5% interest, an IO repayment might be $1,667 per month, whereas a P&I repayment could be $2,147. After the IO period, your repayments will increase significantly as you start paying off the principal.

How Interest-Only Loans Can Affect Your Long-Term Costs

Interest-only loans may seem attractive due to lower initial repayments, but they often lead to higher overall costs. A calculator helps illustrate the difference. For instance, a $500,000 loan with 5 years of interest-only repayments followed by P&I repayments for 25 years will result in a higher total interest cost compared to a standard 30-year P&I loan. This can help borrowers understand the trade-offs and plan better.

Does the Frequency of My Repayments Matter?

Yes, the repayment frequency can impact the total interest you pay over the life of the loan. Weekly or fortnightly repayments allow you to make additional payments each year compared to monthly repayments, potentially reducing your overall interest. For example, a $350,000 loan at 4.5% interest with fortnightly repayments might save you thousands in interest compared to monthly payments, as you effectively make an extra monthly payment each year.
