Term deposits

A term deposit provides a guaranteed return on your investment, allowing you to lock away your money and earn a fixed interest rate for a set term. Both NAB and Commonwealth offer term deposits for periods ranging from one month to five years, with different interest rates available depending on the amount you deposit and the term you select. There are no monthly account fees to contend with and both banks require a minimum investment of $5,000.

The table below outlines the interest rates that apply to term deposits of $5,000 with CommBank and NAB. As you can see, the highest rate available depends on the term you choose. For example, while CommBank offers a 0.40% p.a. higher rate for one-month deposits, NAB’s rate for 36-month deposits is 1.30% p.a. higher than CommBank’s.

Online banking

From checking your account balance to paying bills and even transferring funds overseas, there’s plenty of everyday banking transactions you can complete via your bank’s online banking portal.

NAB’s portal is known as NAB Internet Banking. It allows you to keep track of your finances 24/7 and offers protection against scams through NAB Defence. You can pay bills, transfer funds, report lost or stolen cards and check your account balance and recent transaction history.

CommBank customers do their online banking through NetBank. This multi-award-winning online banking platform is designed to make it convenient and easy to manage your finances whenever you want. It allows you to do everything from paying bills and viewing online statements to transferring funds to more than 200 countries around the world. There’s also a Security Guarantee to cover losses from unauthorised transactions.

The tasks and transactions you can perform are fairly similar between the two platforms, so deciding which one is better may come down to your opinion of which one is easier to use. CommBank offers a demo NetBank account to help you sample the features on offer, while you can also read reviews of each platform and ask family and friends for their recommendations.

The verdict

There’s no easy answer to the question of which bank is better for savers, NAB or Commonwealth Bank.

So before you choose NAB, Commonwealth Bank or any other bank to handle your savings or transaction account, compare the products and services on offer from each bank. This will help you make an informed decision about which bank is right for you.
