Comparison rate

Why the comparison rate matters

Australian lenders must publish a comparison rate alongside the advertised rate. It bundles most fees into a single figure so you can compare loans fairly, since a low headline rate with high fees can cost more than a slightly higher rate with none. Use the comparison rate when you shop, and enter it here for a truer repayment.

Offset and extra repayments

Offset accounts and fortnightly repayments

Many Australian loans come with an offset account: money sitting in it reduces the balance interest is charged on, without you formally repaying. Paying fortnightly rather than monthly is another common tactic, since 26 fortnightly payments add up to more than 12 monthly ones over a year. Toggle fortnightly above, or add extra repayments, to see the effect on your interest and term.

Insurance

LMI under 20% deposit

With a deposit under 20%, lenders usually require Lenders Mortgage Insurance. It protects the lender, not you, and the premium can be substantial, so it is often worth weighing against saving a larger deposit or using a guarantor. LMI is commonly added to the loan.

Questions & answers

Frequently asked

What is a comparison rate?
A single figure Australian lenders must show that combines the interest rate with most fees, so you can compare loans on a like-for-like basis rather than on the headline rate alone.
How does an offset account work?
It is a transaction account linked to your loan. The balance in it offsets your loan balance, so you are charged interest only on the difference, while your money stays accessible.
Should I pay weekly, fortnightly, or monthly?
Fortnightly or weekly repayments squeeze in the equivalent of an extra monthly payment each year, which shortens the loan. Monthly is simpler. The savings from fortnightly can be meaningful over 30 years.
What is LMI?
Lenders Mortgage Insurance, required on most loans with a deposit under 20%. It protects the lender if you default and is usually added to your loan amount.
