FAQ
Questions about offset accounts and Offsetly
What is an offset account?
An offset account is a transaction or savings account linked to your home loan. Its balance is subtracted from your loan balance before interest is worked out, so $50,000 in offset against a $500,000 loan means you are charged interest on $450,000.
How much can an offset account save?
It depends on your rate, loan term and how much you keep in offset. As an example, a $500,000 loan at 6% over 30 years with $50,000 in offset and $500 a month in extra repayments pays about $306,000 less interest and is repaid 11 years and 7 months sooner. Offsetly works this out for your own figures.
How is stamp duty calculated?
Stamp duty (called land transfer duty in Victoria) is a state or territory tax on buying property, charged on a sliding scale by price. Each state has its own scale and concessions. Offsetly uses each state's general residential rates and shows registration fees too; first home buyer concessions are not included.
What is a rate-rise stress test?
It shows your repayment if interest rates rise. Offsetly shows rises of 0.25, 0.5, 1, 2 and 3 percentage points; 3 points is the serviceability buffer Australian banks assess new loans against.
Do I need an account?
No. Every calculator works without an account and runs on your phone. You only link Offsetly to your mortgage broker if they send you a code.
How do I link Offsetly to my broker?
If your broker uses MyLoanBook, they can send you a one-time code by text or email. Enter it in Offsetly within 48 hours. Once linked you can see your loan as your broker's statement reports it, answer their check-ins and ask them to review your rate. You can unlink at any time.
Is Offsetly credit advice?
No. Offsetly gives general information only and doesn't take your objectives, financial situation or needs into account. Speak to your broker or lender before making a decision.
