Interest is paid once at maturity as simple interest, the usual convention for shorter terms.

Before you lock it away

A term deposit trades access for certainty — your rate is fixed, but breaking the term early usually means reduced interest and notice. Compare current rates and terms on our term deposit comparison, and weigh it against an at-call account with our term deposit vs savings account guide.

FAQs

How is term deposit interest calculated?

It depends on payment frequency. On terms of 12 months or less paid at maturity, banks generally pay simple interest. Paid periodically and reinvested, it compounds; paid out, it doesn’t.

Paid out or reinvested?

Reinvesting earns slightly more (interest on interest); paying it out gives regular income. Toggle “reinvest interest” above to compare.

What happens at maturity?

There’s usually a short grace period to withdraw or change. Do nothing and many banks auto-roll into a new term, sometimes at a lower rate — check the renewal rate near maturity.

Is this calculator financial advice?

No — a general estimate that ignores tax on interest (which is taxable income). Banks may round or apply their own conventions. Confirm with your bank.

Estimates only, for general information. Terms over 12 months paid at maturity may compound at the bank’s discretion; this tool treats maturity payments as simple interest. Excludes tax on interest and any fees. Not financial advice — confirm figures with your bank.
