Calculation breakdown
- Maturity value
- Maturity = deposit × (1 + rate)^(months ÷ 12)
- Interest
- Interest earned = maturity value − deposit amount
Worked example
A $20,000 term deposit at 4.5% p.a. for 12 months grows to about $20,900, earning roughly $900 in interest at maturity.
Assumptions
- Assumes interest compounds annually to the rate entered and is paid at maturity.
- Excludes tax on interest earned and any early withdrawal penalties.
How this calculator works
Enter your deposit amount, annual interest rate and term length to estimate the total interest earned and the maturity value of an Australian term deposit. It supports simple compounding at maturity, the way most retail term deposits are structured, so you can compare offers from different banks.
Frequently asked questions
Is interest paid during the term or at maturity?
Most Australian term deposits pay interest at maturity for shorter terms, or annually for longer terms; this calculator assumes interest compounds to maturity.
Is term deposit interest taxable?
Yes, interest earned is assessable income and must be declared on your tax return in the year it is received or credited.
Can I withdraw early?
Early withdrawal usually reduces the interest rate or incurs a break fee; check your bank's terms before locking in funds.
