How to use the personal loan calculator

To use the personal loan calculator, you’ll need to enter some details about your loan. These are explained below:

  • Borrowing Amount — The amount of money you are looking to borrow from a lender under a personal loan agreement, including any fees included in the loan.
  • Interest Rate — This is the interest rate the lender will apply to your personal loan, and is used to calculate both the total amount of interest you will pay over the loan period and your scheduled repayment amount. Personal loan interest rates can be fixed or variable: If you have a variable rate of interest, you will have difficulty accurately determining your payments over the life of your loan.
  • Loan Term — The length of your personal loan as dictated by your loan agreement. The shorter your loan term, the higher your scheduled repayments will be. Your loan term is important as it will allow you to accurately calculate your monthly, fortnightly, or weekly payments through an Annual Percentage Rate (APR) calculation, provided you are working with a fixed interest rate.
  • Establishment Fees — Any upfront fees charged by the lender when creating the secured personal loan agreement. Establishment fees are included in the calculation for your repayments to provide a more accurate total loan amount.

Once you have filled in your personal loan details, simply click ‘See My Repayments’ to view an estimated repayment amount.

You can then select Monthly, Fortnightly, or Weekly repayments to see what your repayment amount will be at various frequencies.

If you are calculating a personal loan with variable interest, you will only be able to calculate the current repayment amount based on the current rate of interest.

Personal loan repayment calculation

The personal loan calculator uses amortisation calculations to estimate interest and repayment amounts. Amortisation is the method of splitting payments between interest and the principal amount to repay the full amount in regular, consistent payments:

  • When you make your first repayment on your personal loan, a greater portion of the amount will go toward repaying the interest.
  • As you continue to meet your repayments, the portion of interest paid on each amount will decrease, and the portion paid on your principal amount will increase.

When you calculate your personal loan repayments using this formula, it allows you to see what your regular repayments will be, and also allows you to estimate your savings should you choose to repay a portion of the loan early.

Personal loan repayment examples are calculated using weekly repayments with a fixed interest rate on a 5-year term. They do not include any fees that may be charged by a lender in addition to interest.
