If you’re ready to open a term deposit, there’s a lot you’ve already figured out. You’ve decided on the length of your term and found the best interest rate, but there’s something you still might be wondering. How do you calculate term deposit interest?

One of the easiest ways to calculate term deposit interest is by using a term deposits calculator. However, you can also estimate your total earnings on your own.

A fixed interest rate signifies what percentage of your original balance your term deposit will earn annually. For example, a deposit of $1,000 at an interest rate of 3 per cent will earn three per cent of $1,000 annually – meaning you’ll earn $30 of interest each year.

You can estimate your interest using three variables. Multiply together your deposit amount, interest rate, and term length and you’ll approximate the interest a deposit will earn. For example, if you invest in a term deposit for $5,000 at an interest rate of 3 per cent for two years, your interest would total $300.

What is the best interest rate for a fixed term deposit?

The best interest rate for a fixed term deposit changes all the time, as interest rates move up and down and banks compete with each other to win market share.

To find the best interest rate for a fixed term deposit, it’s helpful to understand how interest rates are applied to term deposits.

There are three factors that determine the fixed interest of term deposits:

  1. The size of your deposit
  2. The duration of the term
  3. The frequency of interest paid

Term deposits vary in duration from one month to five years or more. Interest rates generally work on a sliding scale; shorter terms get a lower rate, longer terms get a higher rate.

Here are a couple of examples of how interest is applied to term deposits.

  • A $10,000 term deposit taken out over 12 months, with interest paid at maturity, might receive a fixed interest rate of 2.20 per cent.
  • A $10,000 fixed term deposit taken out over 12 months, with interest paid quarterly, might receive a fixed interest rate of 2.00 per cent.

Using the size of your deposit, the duration of the term and how often you want to be paid interest, you can shop around for the best interest rate for a fixed term deposit.

How often do term deposit rates change?

One of the advantages of a term deposit is that this type of investment enjoys a fixed interest rate. This means that the interest rate that you have signed up for will not change during the period of your term deposit, regardless of rising or falling market interest rates.

However, it is important to be aware of the end of your term deposit. Once your term ends, whether this is in three months or three years, many banks will default to rolling over your deposit into a new term, sometimes with a lower interest rate. Once your term deposit rolls over, you will then be locked into this new fixed interest rate for another term.

Make sure to use the grace period at the end of your term to your advantage. Shop around for a competitive interest rate and reinvest your money accordingly.

What is a term deposit rate?

The term deposit rate is the agreed interest rate for your term deposit. It remains fixed for the term of the deposit.

For example, if you deposit $5,000 for 12 months at a 2.5 per cent term deposit rate, that 2.5 per cent term deposit rate will be fixed for the entire 12 months and won’t change until the term matures.

The term deposit rate is one of the most important factors to consider when comparing your term deposit options. The general rule of thumb is that the longer the term, the higher the term deposit rate.

Term deposits are a popular type of investment because they’re safe and provide reliable returns.

The return you get on your term deposit will be determined by the amount you initially invest, the amount of time you choose to invest it for, and the term deposit rate.

What is a term deposit?

A term deposit is an investment savings account. A term deposit usually pays a higher rate of interest than a regular savings account, with the interest rate fixed for the term (or duration) of the deposit.

You can open a term deposit account for one month or up to five years depending on your investment goal, and invest as little as $500 to start earning a profit.

With a term deposit, you get to decide how much you want to invest (the principal or deposit), for how long (the term or duration) and the frequency of interest payments.

A term deposit represents a secure form of investment, unlike trading in shares or purchasing real estate. And a term deposit up to $250,000 is protected by the government guarantee.

How long is a term deposit?

A term deposit refers to when you lock your money in an account for a certain period of time and at a specified interest rate. You will not be able to access your money for the length of the agreed term without incurring a penalty fee.

A long term deposit generally refers to a term deposit that lasts for more than 12 months – which in some cases may be as long as 10 years.

Usually, the longer you store your money, the better the interest rate you’ll get, so a long term deposit will tend to pay higher interest than a short term deposit.

At the end of the term, you can roll over the money (plus the interest you’ve made during the term), or you can withdraw it all.

How safe is a term deposit?

You may have heard that a term deposit is a type of investment, different to a traditional savings account. All investment comes with inherent risk, so it’s important to know how safe a term deposit is before committing.

Term deposits offer a fixed interest rate which is guaranteed, so you do not have to worry about rising or falling interest rates when investing. You can add up how much interest you will earn over your fixed term, and this will be paid into your account per the conditions of your term deposit.

Term deposits with authorised deposit-taking institutions are also guaranteed for up to $250,000 by the Financial Claims Scheme, so you don’t have to worry about the bank collapsing either.

The only inherent risk of a term deposit is if you may need to break it early. If this happens, you will need to pay a breakage fee and possibly sacrifice some of your interest as a penalty. But if you know you can invest a certain amount of money for a fixed period of time, you can rest assured that a term deposit is a safe investment option.

Is term deposit interest taxable?

The interest that you earn from your term deposit is considered taxable income. Because your term deposit interest is taxable, it should be disclosed on your annual tax return.

It’s important to note that circumstances may differ depending on whether you provided the account holder with your tax file number (TFN). If you did not supply your bank or other financial institution with your TFN, they are typically required to withhold tax from your interest earnings.

If you’ve invested in a deposit that lasts longer than 12 months, you’ll need to claim your earned interest in the year that you received it. For example, if you receive interest monthly, you’ll need to claim your earnings at the end of the financial year. However, if you only receive interest at maturity, you should claim your earnings in the year that you received the lump sum of interest.
