Term deposit and savings calculator explained

How do I use the term deposit and savings calculator?

The term deposit calculator is simple to use, with clear areas for you to enter the amount you wish to deposit, the interest rate you have been offered and the amount of time you intend to leave your savings locked up. Choose whether you want interest to be added to your deposit sum, so it compounds, or whether the interest will be paid into a separate account, to produce an income stream. 

Once completely entered, you’ll be able to see the results of how much you’re set to earn. From there, you can compare interest rates with Savvy and use the calculator to see for yourself how a small increase in the interest rate can have a large effect on the size of your nest-egg at the end of your savings period.  

How do term deposits work?

A term deposit is an agreement to lock away your savings for a set period in return for a fixed rate of interest. Banks and financial institutions offer different interest rates based on these periods, which are known as the term of the deposit. During the agreed term, you won’t be able to add to your savings or withdraw any money. If you have to withdraw your funds early, you’ll have to give notice and will be penalised for early withdrawal.  

There are short term deposits, which are less than 12 months, and long term deposits, which are between one and five years in length. When you deposit your savings, you choose how long you wish to deposit them for and receive a fixed interest rate in return. The most popular terms are six, nine and 12 months. At the end of the deposit period, you can choose to roll your funds over for another term or withdraw them and the interest earned to another transaction or savings account

What is compound interest and how does it work?

Compounding means the interest earned is added back into the same deposit account where your savings are stored, so you end up earning interest on the interest. The effect of compounding means your savings will grow more rapidly over time. 

For example, if you deposit $10,000 at an interest rate of 2.5% p.a., you’ll earn $250 in interest at the end of 12 months. If this is added to your original sum annually, you’ll be earning interest on $10,250 in the second year.  

However, if the interest earned is added back in more often (such as monthly or quarterly), you’ll start earning interest on boosted sum sooner. The more frequently your interest is compounded, the quicker your savings will grow.  

Financial institutions calculate interest daily, so if you decide to add the interest back into your account monthly, you can watch your savings grow month by month. However, not all banks allow monthly interest to compound, and if they do, the rates offered can be lower than if you opt to have your interest paid less often. For this reason, it’s important to compare terms and interest rates with Savvy before making your final investment decision.

What factors will affect how much interest I earn?

Top tips about how to maximise your term deposit interest

Deposit as much as possible

Naturally, the more you can lock away in a term deposit, the more interest you’ll earn and the faster your savings will grow. Invest as much as possible in your term deposit, as you won’t be able to add to it once you’ve committed to a particular sum. 

Invest your savings for as long as possible

Term deposits are ideal for people who tend to spend any surplus money they earn. Longer terms generally come with higher rates, so choosing as long a term as possible will help you maximise the benefits of having your savings locked away out of reach. 

Leave your savings alone for the entire term

Even if things get tough, resist the urge to withdraw your funds from a term deposit early, as not only will you earn less interest, but you may have to pay an early withdrawal administration fee or receive a rate reduction.

More of your questions about term deposits answered

What are the minimum and maximum amounts I can invest in a term deposit?

All banks and financial institutions have their own maximum and minimum term deposit limits. Some allow you to open a deposit with as little as $500, whilst others require $1,000 up to a $10,000 minimum. The same applies to maximum deposit sums. These can range from $250,000 all the way up to $5 million or more by special arrangement. 

What is the longest period I can invest in a term deposit?

The maximum length of term deposits in Australia is five years. Prior to the global financial crisis, ten-year term deposits were on offer, but they were withdrawn after the GFC.  

What will happen if I urgently need to access my savings due to an emergency?

If you have to dig into your savings early, you’ll usually have to give notice of your intent to break your agreed term. This notice ranges from seven days up to 31. You’ll also suffer a reduction in the interest you’ll earn, and in some cases will have to pay an early redemption fee, which is often around $30. How much interest you’ll lose will depend on how early in the term you have to break the deposit agreement, but can be as much as 90% if you do so early on in your term.  

How old do I have to be to open a term deposit?

All banks and financial institutions have a minimum age limit they allow to open a term deposit. In most cases, the minimum age is 18, but some banks do allow children as young as 12 or 13 to open a term deposit account. 

Is it possible for two people to open a term deposit together?

Yes – many, but not all, banks allow joint term deposits. There tend to be many involved terms and conditions around joint term deposit accounts, mainly centred on what happens if one of the partners dies during the term of the deposit, but also who has permission to open and close the account. 

Can I have multiple term deposits at once?

Yes – it’s possible to hold multiple term deposits, either with the same bank or financial institution or spread across several different ones. Some investors hold multiple term deposits with different maturity dates, so if they do suffer financial hardship, they’ll have a deposit which is close to the expected maturity date to minimise interest loss for early withdrawal. In addition, if you are investing in a period of rising interest rates, it might make more sense to choose shorter deposit terms and roll your funds over for a potentially higher interest rate.
