Then enter any lump sum to be paid on the loan and the number of the month in the loan term where the lump sum is added (eg, month 1, 2... 10, 12 of the loan term etc) and/or the amount of any extra repayments and the number of the month in the loan term where the lump sum is added (eg, month 1, 2... 10, 12 of the loan term etc).

To compare one set of criteria with another (for example monthly vs. weekly repayments or one lump sum v. another) select the COMPARE button. To return to one set of loan criteria select the COMPARE button again. To see the results of you calculation click on the CALCULATE button.

About this calculator

The Advanced Repayment calculator allows the user to calculate their loan repayments and see the effect of making additional repayments:

  • Entering fixed interest rate information is optional. If your loan is a variable interest rate and you only know the current variable rate enter this in the Interest rate field.
  • The calculator is based on interest being calculated and charged monthly.
  • Additional repayments, both one off and every month, are assumed to occur during the month, hence are deducted prior to interest being calculated. Similarly, redraws are added to the balance prior to interest being calculated.
  • Entry fees are added to the amount borrowed.
  • The graph and updated loan summary show the difference between the initial loan details entered and all the additional repayments and redraws listed.
  • If the user enters both an initial fixed interest rate and a variable interest rate the repayments for both these periods are set prior to any additional repayments or redraws being made. This means that if the borrower makes additional repayments in the initial period of the loan, they will reduce the term of the loan not the required repayment in the second period of the loan.
  • The final repayment is the repayment made in the last period of the loan to pay out the remaining balance.
