Understanding Fixed Loan Prepayment Interest


What is fixed loan prepayment interest?

Fixed Loan Prepayment Interest, which is also referred to as a 'break fee', may be payable if you choose to pay off your fixed rate home loan before the end of the fixed interest rate term. Fixed Loan Prepayment Interest may also be payable if you make voluntary payments of more than $10,000 of your outstanding loan balance in a calendar year, or if you to change to a different interest rate or loan type.


Why is fixed loan prepayment interest charged?

When you take out a fixed rate home loan, you get the certainty of knowing how much the loan repayments will be over the fixed term you choose. If you decide to repay your home loan early, make additional loan repayments, or switch to a different interest rate or loan type (e.g. a lower fixed rate) before the end of the fixed term, the Bank may incur a loss of income. Fixed Loan Prepayment Interest is charged in order to recover this loss of income. 


How is fixed loan prepayment interest calculated?

The calculation for Fixed Loan Prepayment Interest is based on a number of factors, including:

  • The amount being repaid early
  • Time remaining in the fixed term
  • Current lending rates
  • Contractual principal and interest repayments of the loan. 

Fixed Loan Prepayment Interest is calculated by comparing the interest that would have been payable for the outstanding time remaining on the fixed term interest rate, to the interest that would be payable if the Bank re-lent the money today. If there is a loss of income to the Bank, then Fixed Loan Prepayment Interest will be payable.

To get an approximate estimate of Fixed Loan Prepayment Interest, the following formula can be used:
Fixed Loan Prepayment Interest = (Loan Interest Rate – Current Rate for remaining term) * Loan Balance * Years Remaining of fixed term

For example, John borrowed $250,000 on a 5 year fixed term at 5.75% p.a. After 3 years, John has $200,000 remaining on his home loan balance and repays the amount in full. Fixed Loan Prepayment Interest is calculated on the $200,000 repaid early, at the difference between John’s existing rate (5.75%) and the current lending rate for 2 years (for this example we'll use 5.50% p.a.). This amount is then multiplied by the years remaining in the fixed term (2 years).

Fixed Loan Prepayment Interest = (5.75% - 5.50%) * $200,000 x 2yrs = $1,000

If John had instead decided to make lump sum payment of $100,000, the Fixed Loan Prepayment Interest would be;

Fixed Loan Prepayment Interest = (5.75% - 5.50%) * $100,000 x 2yrs = $500

If the current 2 year lending rate was 6.00% (i.e. higher than John’s existing loan rate) then no Fixed Loan Prepayment Interest would have been charged.

Please note: The above examples are simplified and the actual Fixed Loan Prepayment Interest calculation is very complex.
