High interest savings accounts with some strings attached

Outside of bonus introductory interest rates, which often only last for a set period of time, some financial institutions may also offer conditional bonus rates. This is where you need to meet certain conditions to receive the bonus interest each month.

For example, you may need to deposit a certain amount of money into your account each month, make no withdrawals during the month, or have a linked transaction account and make a specific number of card purchases each month.

Be aware that for some of these accounts, if you fail to meet the bonus interest conditions, you’ll receive little or no base interest. Check with the provider to confirm what conditions may apply.

How to find the best high interest savings account

Although a high interest savings account yields high returns on your savings, the interest rate shouldn’t be the only thing you consider. The best savings account for you will differ depending on your needs and circumstances, so you should consider the following questions when comparing accounts:

• What type of saver are you? Are you a regular saver who can abide by stricter saving conditions for higher interest rates? Or do you need flexibility that allows you to save without worrying about any finer details?

• What is the interest rate? Although it isn’t the only factor to consider, when it comes to savings the higher the interest rate, the quicker your savings will grow.

• Are there any interest rate conditions? If there are certain conditions that need to be met in order to acquire the high interest, do they match your saving style? If there are a number of requirements to meet, do you think you’re able to keep on top of them each month?

• What are the account fees? Fees can erode your savings, so it’s best to search for a fee-free account, or one that waives fees if you meet certain conditions. Check for account fees and any transaction fees that may apply.

• Does the account have any useful features? It’s also worth considering if there’s a linked transaction account and what features it provides. For example, some of our 5-Star Rated bank accounts offer refunds on international transaction fees or cashback on eligible purchases or bills.

What are the benefits of a high interest savings account?

The main benefit of a high interest savings account is the interest you’ll earn and that it’s one of the easiest and least risky ways to grow money you may have stored away. This low associated risk comes from the Federal Government’s Financial Claim Scheme (FCS), which guarantees deposits up to $250,000 per account holder per authorised deposit taking institution (ADI).

On top of that, it’s also flexible, so you’re generally able to deposit or withdraw your savings at any time.

To maintain your high interest savings, you could also automate them by setting up a recurring payment transfer between your transaction and savings accounts or request that your employer pay your wage directly into your savings account.

Unlike a term deposit, the flexibility of a high interest savings account may mean it’s easier to budget and manage emergency funds while still being able to accrue interest from your savings.

But keep in mind, some savings accounts only have high conditional bonus interest rates, so if you do end up withdrawing from your savings, it may mean you lose out on the high interest earnings for that month, depending on your account’s terms and conditions. Even so, you can always try to meet the requirements the next month.

What is a high interest savings account?

In Australia, financial institutions such as banks, credit unions and other deposit-taking institutions (DPIs) generally offer a transaction account or savings account, or a combination of the two.

Savings accounts are designed to earn you interest while limiting withdrawals, and, unlike a transaction account, usually don’t allow for cash withdrawals or direct spending through the account. A high interest savings account, as the name suggests, comes with a high interest rate, which means you can potentially earn more money through interest payments on your savings.

How do high interest savings accounts work?

High interest savings accounts often come with certain terms and conditions, such as limited withdrawals and a set amount that must be deposited into the account each month in order for your savings to accrue the higher interest rate.

These terms and conditions are often put in place to encourage you to regularly deposit into your savings account and withdraw less, which typically results in more interest being earned.

Another common feature to a high interest savings account is the opportunity to earn compound interest. Compound interest allows you to earn interest on the interest you’ve already earned and is calculated as a percentage of the total balance in your savings account.

In other words, you’re able to earn interest on whatever the current balance is in your savings account, even if part of that balance comes from the interest previously paid by the financial institution.

To give you a better idea, here’s an example of the kind of interest you could potentially earn on a savings account with compound interest.

The table below shows the accumulated interest earned for a $10,000 deposit into a savings account with compound interest at 5.00% per annum that’s paid monthly (with no additional deposits made).

Key features of a savings accounts

• Higher interest rates: One of the main features of a savings account is the ability to earn interest, which is typically not offered by a transaction account.

• Variable interest rates: Another aspect to a savings account is the impact of variable interest rates, which can go up or down depending on the economic conditions (e.g. the cash rate). This is unlike a term deposit, which locks in a certain interest rate for a set period of time.

• Compound interest: A common feature to high interest savings accounts, compound interest allows you to earn interest on the interest you’ve already earned and is calculated as a percentage of the balance in your savings account.

• No account fees: The majority of savings accounts have no associated ongoing account fees, but often require a linking transaction account, which might have an account fee. You may also be charged a fee for certain transactions or if you require over-the-counter services or ATM access.

• Accessibility: Although not as accessible as a transaction account, you can generally transfer money out of your savings account at any time. This means if you suddenly require the funds, you’re able to access your savings. Just be mindful you may lose out on any conditional bonus interest linked to the account for that month (if your account has a conditional bonus interest rate).

High interest savings accounts also tend to have terms and conditions that need to be met for the account to accrue higher interest than a standard savings account.

Can the interest rate of a high interest savings account change?

Yes, the interest rate you’re offered when opening a savings account may change over time. This is due to most savings accounts having a variable interest rate, which means the rate can change due to economic conditions (e.g. the lowering or raising of the cash rate).

It can be important for savers to keep an eye on the RBA’s cash rate decisions, as the raising of the cash rate could see their interest rate increase, whereas a cut could see their rates fall.

How to apply for a high interest savings account

A savings account can generally be applied for and opened like any other bank account. Depending on the financial institution, you may be able to apply online within minutes. That being said, you may also have to open a linked transaction account first in order to apply for the savings account of your choice.

Some general eligibility requirements to open a savings account in Australia are:

• Be an Australian resident with an Australian postal address

• Provide some form of identification documents (e.g. driver’s licence or passport) and other personal information in order to confirm your identity

• Provide your tax file number (TFN) if you don’t wish the bank to withhold tax on the interest you’re paid

• If you’re a minor (those under 16), you may require the assistance of a parent or guardian in order to open an account.
