Frequently Asked Questions

What is a good home loan interest rate in Australia?
Variable home loan rates in Australia typically range from around 5.5% to 7.5% depending on the lender, loan type and your financial profile. Owner-occupier P&I loans tend to have lower rates than investor or interest-only loans. Always compare rates across multiple lenders and consider using a mortgage broker.
How much superannuation will I have at retirement?
Your super balance at retirement depends on your current balance, salary, contribution rate, investment returns and years to retirement. As a rough guide, the ASFA Retirement Standard suggests a comfortable retirement for a single person requires around $595,000. Use our Superannuation Projector to estimate your balance based on your own numbers.
How do I pay off my credit card faster?
The fastest way to pay off credit card debt is to pay more than the minimum each month. Even a small extra payment each fortnight can save thousands in interest and years off your debt. Our Credit Card Payoff calculator shows exactly how much you'll save with extra repayments.
What is compound interest and how does it work?
Compound interest means you earn interest on your interest, not just your original deposit. Over time this creates exponential growth — the longer your money is invested, the more powerful compounding becomes. For example, $10,000 at 7% p.a. grows to around $76,000 over 30 years with no additional contributions.
Should I choose fortnightly or monthly mortgage repayments?
Fortnightly repayments result in 26 payments per year — the equivalent of 13 monthly payments. This extra month's payment each year can save tens of thousands in interest and cut years off a 30-year loan. Our Mortgage Calculator shows the difference side by side.
