Calculate if I could save using an offset account

Play with this calculator to explore how much you could save on your home loan interest and term.

 

How does an offset account work? 

Normally, you accrue interest on your whole home loan balance. But when you link our everyday Westpac Choice account to our Rocket Repay home loan, it becomes an offset account. Every dollar there reduces your loan interest, while giving you easy access to it for day-to-day living, or a rainy day.

Why choose our variable home loan with offset

Save by packaging

Package your loan to save on fees, get a home loan rate discount, and pay no annual fee on a Westpac credit card ($395 annual package fee applies#).

Easy access to your money

Our offset account has all the benefits of our Choice everyday account, like a Debit Mastercard, ATM access, Apple Pay and Google Pay.

Save interest with 100% offset

Every dollar in your offset account counts towards reducing the interest on your linked home loan.

Flexible features

Split your loan across variable and fixed rate, redraw anytime with no fees, and enjoy unlimited extra repayments on the variable portion.

Everything offset

FAQs

It’s an everyday bank account linked to a variable home loan that lets you reduce the interest paid on your loan. 


Every day, 100% of the balance in your Westpac transaction offset account is ‘offset’ against the amount owed on your Westpac Rocket Repay Home Loan. As interest is calculated daily and charged monthly, only the net amount (your loan balance minus your offset balance for that day) attracts interest.

This mortgage offset calculator offers an estimate of the interest and time you could save by having money in your Westpac offset account, and is based on the info you’ve entered. 

 

Calculator assumptions 

  • Interest rate. This calculator doesn’t take into account compound interest savings. 
  • Interest and loan term savings. This calculator compares a home loan without an offset account, to a loan linked with an offset account. Total Interest Saved = (Total interest paid on loan without offset) - (Total interest paid on loan with offset). 
  • Extra repayments. Calculator is based on your offset account balance, and doesn’t take into account any extra mortgage repayments you might make to your home loan account. 
  • Weekly, fortnightly or monthly repayments. Your initial loan will be set up as monthly. Weekly and fortnightly repayments are only available with P&I. To calculate these, we multiply your P&I monthly amount by 12 to get a yearly value, then divide either by 26 for fortnightly or 52 for weekly, and round it up.  

 

*Comparison rate: The comparison rate is based on a loan of $150,000 over the term of 25 years. WARNING: This comparison rate is true only for the examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate.
