Why fix your rate

  • Rate fluctuations: protect yourself from the uncertainty of rate fluctuations by fixing over your chosen term.
  • Manage your cash flow: better plan your expenses by fixing your rate. You'll know how much interest you need to pay every month or you can pay your interest up-front.
  • Tax: by pre-paying your interest payments in full, you may be able to claim a tax deduction in the current financial year.

Fixed vs Variable Interest Comparison Calculator

To help you decide whether a fixed or variable rate is best for you, we have developed a Comparison Calculator.

Use this calculator to compare the potential interest savings between fixed and variable rates over different terms. You can also simulate potential future movements in the variable interest rate, and estimate the outcomes of fixing all, or just a portion of your loan balance.

While gearing can multiply your gains, it can also increase your losses when a trade doesn't go your way. CommSec provides you with a suite of tools and information to help you effectively manage risks and maximise your returns.

How to use the calculator

  • Enter your loan balance, the fixed period and the portion of your loan to be fixed
  • Enter your applicable margin lending fixed interest rate. If you're not sure of your available rates, contact our Margin Loan specialists on 13 17 09 (+61 2 9115 1402), between 8am and 6pm (Sydney time) Monday to Friday.
  • Adjust the variable interest rate to see how future rate movements affect your interest payments over the following 1-5 years.

How to fix your rate

  • Decide on the loan amount, fixed term, and payment option for your fixed request.
  • To fix your loan for 12 months, login and go to:
    Portfolio > Accounts > Select your margin loan account > Transfers > Select “Margin Loan Transfers” > Select "Variable loan to fixed loan", and submit your completed fixed loan request.
  • To fix your loan for two years, or to discuss other fixed terms, contact our Margin Loan specialists.
