How to calculate term deposits?

You can use the free term deposit calculator in this guide to find out exactly what your term deposit will be worth based on the deposit size, the interest rate and the term length.

How much interest can I earn on $500,000 in Australia?

The amount of interest you'll earn on a term deposit with $500,000 will depend on the interest rate and term length. For example, if you had a 12-month term with a fixed rate of 4% p.a., using the term deposit calculator above shows you can earn $20,000 interest.

The term I chose is for four years, but that is not given as an option in the calculator. What should I do?

The calculator recognises terms in months, so you only need to multiply the number of years by 12. For example, in this case you would choose a 48 month term for four years.

I want to make at least $500 in interest, how would I figure that out?

You would have to play with the numbers that you insert into the field, particularly the length of terms as this is the option you have the most control over, until you come out with the earnings you are striving for.

Can I use this calculator for a regular savings account?

No, it won't work for a savings account. There are other variables to consider with a typical high interest savings account that are not needed with the term deposit calculator. If you are interested in comparing the interest earning benefits of both types of accounts, you can see a savings account vs term deposit calculator that could help.

How to use the term deposit calculator

Deposit amount. Enter the amount of money you plan to invest into the term deposit account.
Term length. Enter the number of months you will be investing for (you can change this to see how it impacts the total interest earned).
Interest rate. Enter the fixed interest rate for the term deposit you are planning to go with (you can compare term deposits in the table below). Pay attention to the details, as in most cases that amount will be different depending on a number of factors including; the length of terms, how much you invest, and how often you are receiving interest payments.

How can the term deposit calculator help me?

Here's a few things the calculator can help with:

See your exact return on investment. Because term deposit rates are fixed, you'll be able to see the exact dollar amount of interest you'll earn. This can help you plan and make long-term goals.
Choose the right term length. By changing the term length in the calculator, you can easily see how the total interest earned changes.
See how much the rate impacts your investment. If you're investing a large amount of money, the calculator can show you how much extra interest you can earn with a slightly higher rate.
See what your payments could be. You can see what your interest payments will look like depending on how frequently you're paid interest.

i put $5000 in a fixed term deposit with com bank in 1980
what would the value be now?

Finder

AlisonApril 6, 2022Finder

Hi Steve,

We’d suggest you get in touch with CommBank directly to speak about your term deposit account. Term deposits usually are opened for a maximum period of 5 years, after this, they may roll over into another term of the same length but with the current interest rate. Interest rates have changed a lot since 1980, so the rate that you were getting when you first opened the account wouldn’t be what you’re getting now.

I’d recommend speaking with CommBank directly.

Thanks,
Alison

I will soon be investing $98000.00. Where can I find the best term deposit with no fees for 24 months. Thanks

Hi John,

Thanks for your inquiry.

Sorry for the delayed reply. Usually, term deposit accounts do not charge a fee, but some banks may charge fees. You can compare your term deposit options. I would suggest that you play with the calculator on top of the table on that page by entering your deposit and term of investment to be able to compare the results.

When choosing an account, it’s ways best to consider some factors like interest rates on the term deposit, what happens if you break the term of your deposit, any ongoing fees that may apply, etc. When you are ready, you may then click on the “Go to site” button and you will be redirected to the bank’s website where you can proceed with the application or get in touch with their representatives for further inquiries you may have.

Cheers,
May
