The short version
- A 5 year term deposit locks your rate for five years, the longest most banks offer.
- It gives certain income for years, but ties your money up.
- Longer terms don't always pay more, so check before you commit.
How term deposits work
You lock an amount away for a fixed term at a fixed rate. You know exactly what you'll earn, whatever happens to interest rates, but you can't add money during the term.
Most banks need 31 days' notice to release money early and reduce the interest they pay you, so only lock away money you won't need.
Pros
- Your rate is locked, so a cut doesn't touch you.
- No fees and no conditions to meet.
- Five years of certain income, useful for retirees planning ahead.
- Holds today's rate if rates fall for years.
Cons
- Your money is locked in, with 31 days' notice and an interest cut to get it out early.
- Inflation can eat into the real value of a fixed rate over five years.
- If rates rise, you're stuck on the old rate for a long time.
Alternatives
- A ladder: splitting your money across several terms, so some comes free every few months and you're not betting on one rate.
- Government or corporate bonds, which can be sold before they mature, though their price moves.
- A high interest savings account, which pays a variable rate but lets you take money out any time.
How to open one
You can open a 5 year term deposit online with most banks in a few minutes.
- Have your ID and tax file number ready. Without a TFN, the bank must hold back tax at the top rate.
- Check the minimum. Many banks need at least $1,000 or $5,000, and some pay more on bigger amounts.
- Choose how interest is paid. At the end of the term usually pays the highest rate; monthly or yearly payments can pay a little less.
- Decide what happens at maturity. Set it to pay into your account, or you may be rolled into a new term at a lower rate.
What to check
- The rate for your exact amount and term. Rates often differ for larger deposits.
- How interest is paid: at the end, or monthly or yearly. Monthly interest often comes at a slightly lower rate.
- What happens at maturity. Many deposits roll over automatically at the bank's rate on the day, which may be lower, unless you give instructions.
- That the bank is an Australian authorised deposit-taking institution. Deposits up to $250,000 per person per bank are covered by the government's Financial Claims Scheme.
