The four numbers you need to know in your life

The four numbers you need to know in your life

Numbers are a big part of our personal finances, and getting it right is vital for our financial wellbeing.

But many Australians are not across some of the most important numbers in their lives, which can have serious financial implications on their finances, particularly in a recession.

By understanding these key numbers, such as the interest rates you’re paying, you can expect to make a more well-informed comparison of different financial product options to make the best decision for you and your family.

Here are some numbers in your life that are important to know (and you don’t have to be a maths whiz to get on top of it).

1. Home loan rate

The largest debt you might hold in your lifetime is likely to be your home loan. The interest you’re facing on this debt could be hundreds of thousands of dollars over the life of the loan.

Despite this, three quarters of mortgage holders aren’t aware of the interest rate they’re paying on their home loan, according to UBank’s 2019 Know Your Numbers Index.

If you’re on a variable rate mortgage, it could make even more sense for you to know your rate as it is more susceptible to changes, depending on factors including the Reserve Bank of Australia’s cash rate movements and competition in the market.

You may think that if you’re on a fixed rate mortgage, you can set and forget your rate as it’s locked in for at least a year. While this is true to some extent, the time will eventually come when your fixed rate period ends. When this happens, your bank will likely revert your home loan rate to its standard variable rate, which is usually much higher than rates you’d otherwise manage to secure through negotiating or through a promotion. This is why it’s important to pay attention to not only your interest rate, but also when your fixed rate term ends. That way, you won’t be caught off-guard when it happens and you’ll be well-prepared to either negotiate with your lender or refinance.

2. Credit card purchase rate

Credit card debt is a problem for many Australians, yet only one in five of those who use the plastic know the interest rate their card is charging them, a 2019 CUA survey found.

Not knowing your credit card purchase rate can be expensive, as it’s common for many to put their everyday expenses onto their plastic. Yet credit card debts often incur high interest charges, sometimes up to 20 per cent, if not paid off in full every month. This is often how many people end up racking large credit card debts without realising.

And it’s not just the interest from your credit card purchases that can snowball. 

If you’ve ever needed to take out cash from your credit card, you may remember the shock when you received your bill. Credit card providers charge interest on cash withdrawals at a different rate, known as the cash advance rate, which is often higher than the purchase rate. On top of this, cash advances don’t have interest-free days, so it’s likely you’ll be charged interest on the withdrawal from day one.

3. Savings rate

As home loan rates fall for borrowers, so is the interest rate you earn from your life savings.

While savings interest rates are remarkably low, many people are keeping their cash close to them as they ride out the bumpy recovery from the recession.

If you have cash to spare, you may be looking to stash your money into your existing savings account or term deposit. Or, you may even be on the hunt for a savings or term deposit account with higher interest.

It should be a priority for savers to find out what interest rate your savings and term deposits are on, and compare it with other potential options, as this can have an impact on what you earn from your savings.

4. Superannuation rate

While your superannuation may not necessarily be at the front of your mind, chances are your nest egg is one of your most important assets. 

What you end up with at retirement is going to depend in part on your super fund’s return rate. It could be a good idea to look at the return rates over a longer term, such as five or 10 years.

Fees also have a major impact on the balance in your super. Even the best performing super fund may not mean much if a big chunk of it is being eaten away at by high fees,

So if your super fund isn’t working as hard as it should be for you, it may well be time to consider switching.

What is the interest rate on savings accounts?

As banks frequently change their rates, the most accurate way to look at interest rates on savings accounts is to use a savings accounts comparison tool. When you look at the savings rate check what the maximum and minimum rates are. Often banks will offer you a promotional rate for the first few months which is competitive, but then revert back to a base rate which can sometimes be less than inflation. Ongoing bonus rates are often a safer bet as they will keep rewarding you with the maximum rate, provided you meet their criteria

How much money should I have in my savings account?

A good rule of thumb when working out a minimum balance for your savings account is to make sure that you’ll earn more in annual interest on your savings than what you’ll be charged in annual fees.

If you’re saving with a specific goal in mind, prepare a budget so the interest you earn on your deposits will help you efficiently reach this goal. Online financial calculators may be helpful here.

Can you have a joint savings account?

Yes. Joint savings accounts can be useful for two or more people wanting to combine their savings to meet shared financial goals, including spouses, flatmates and business partners.

Some joint savings accounts require all parties to sign before they can access the money. While less convenient, this extra security can help encourage all parties to meet their shared financial goals.

Other joint savings accounts allow any of the account holders to access the money. These accounts can be convenient for financially responsible couples that trust one another implicitly. 

Can you set up a savings account online?

Yes. Several large and small banks offer online applications for savings accounts, and there are also online-only financial institutions to consider.

Online-only savings accounts are often less expensive than other savings accounts, though they may not offer the same flexibility, features, or face-to-face service as more traditional savings accounts.

What is a good interest rate for a savings account?

A good rule of thumb to keep in mind with savings accounts is to look for a rate that is higher than the CPI inflation rate. This number is constantly changing, so check the Reserve Bank of Australia’s page. If you aren’t earning interest above this then the value of your money will go backwards over time.

How does interest work on savings accounts?

The type of interest savings accounts accrues is called compound interest. Compound interest is interest paid on the initial deposit amount, as well as the accumulated interest on money you have. This is different from simple interest where interest is paid at the end of a specified term. Compound interest allows you to earn interest on interest at a higher frequency. 

Example: John deposits $10,000 into a savings account with an interest rate of 5 per cent that he leaves untouched for 10 years. At the end of the first year he will have $10,512 in savings. After ten years, he will have saved $16,470.

How to open a savings account for my child?

Some banks and financial institutions allow parents to open a bank account for their child as soon as it is born, and start depositing funds to go towards the child’s future.

Children’s savings accounts generally don’t have fees, and are structured to help develop positive financial habits by limiting withdrawals, encouraging regular deposits, and earning interest on the savings, similarly to standard savings accounts.

Who has the highest interest rates for savings accounts?

As banks frequently change their rates, the most accurate way to know who currently has the highest interest rate is to use a savings account comparison tool.

What is a savings account?

A savings account is a type of bank account in which you earn interest on the money you deposit. This makes it one of the easiest and safest investment tools.

Can I overdraft my savings account?

A lot of savings accounts won’t let you overdraw. Some will allow this feature but you’ll need to apply first. It’s best to read the fine print and check with your lender whether this is a feature they offer. It can be a helpful addition, but as your lender can charge you a fee as well as interest for going into negative numbers, it’s best to avoid overdrafting when possible.

Can you direct deposit to a savings account?

Yes. You can make one off payments or set up regular direct deposits into a savings account. This can be organised easily through online banking or by making deposits in a branch. Talk to your lender to find out the easiest way for you to set up direct deposits.

How do I open a savings account?

Opening a savings account is a relatively simple process. If you’ve found an account with a suitable interest rate, you’ll just need to get in contact with your chosen lender via a branch, phone call or hop online to begin the process. 

You may be required to provide:

  • Personal details, including identification (driver’s license, passport etc.)
  • Tax file number
  • Employment details

How to make money with a savings account?

Savings accounts make you money by earning interest on your savings. The more money you deposit, the longer you leave it in the account, and the higher the account’s interest rate, the more interest you’ll be paid by the bank or financial institution, and the more your wealth will grow.

To make sure your savings account makes money and doesn’t lose money, it’s important to maintain a large enough minimum balance that the annual interest earned exceeds any annual fees charged on the account.

Can you set up direct debits from a savings account?

It’s not usually possible to set up a direct debit from your savings account to cover ongoing expenses or bills, as savings accounts are structured around growing your wealth by earning interest on regular deposits, and discouraging withdrawals.

Some transaction accounts allow you to set up direct debits and also earn interest, though you may not enjoy as much flexibility as a dedicated transaction account, or get as high an interest rate as a dedicated savings account.
