Term deposit early withdrawal calculator: interest, fees and payout
Estimate what remains after an early interest adjustment and administration fee, using a worked ANZ example and your own bank's confirmed terms.
An early withdrawal can cost you part of the interest already earned, a separate administration fee and time waiting for the money. Those are three different things. The interest you would have earned by leaving the deposit until maturity is a fourth figure—not another fee the bank charges you.
In ANZ’s published example, a $10,000 deposit at 5% earns $375.34 over 274 days. After the example’s 40% interest reduction, $225.21 remains. Subtracting a separate $30 administration fee leaves $195.21 of net interest. If no interest has already been paid and there are no other adjustments, the corresponding estimated payout is $10,195.21.
That is an illustration, not a current rate offer or a quote for your account. The calculation below separates the components so you can replace the assumptions with the terms your bank confirms.

Start with the payout date, not just the penalty
A lower estimated cost is not useful if the money arrives after you need it. ANZ Advance Notice Term Deposits normally require 31 days’ notice for early access. Ordinary ANZ Term Deposits and Advance Notice products are distinct; do not apply that notice rule to every product or bank.
The terms also qualify the timing. Business-day adjustments can matter, and giving notice within 31 days of maturity does not necessarily require an earlier payout. Hardship provisions may help in particular circumstances, but approval is not guaranteed.
Ask the bank for the expected release date first. Use the interest-accrual days it confirms for that date, rather than automatically using the date you request access. The ANZ terms dated 1 December 2025, printed pages 47–53, are the source for the ANZ example here. Your own product and contract remain the authority for your withdrawal.
Calculate earned interest, its reduction and the fee separately
For a simple-interest estimate using ANZ’s stated 365-day basis:
Accrued interest = principal × annual rate × elapsed interest days ÷ 365.
Enter a 5% annual rate as 0.05 in that formula. Then multiply accrued interest by the reduction percentage to estimate interest lost. Subtract that reduction to find retained interest, and deduct the administration fee separately.
ANZ’s published early-withdrawal bands use the proportion of the original term elapsed. They reduce accrued interest—not the principal by that percentage.
| Original term elapsed | Reduction in accrued interest |
|---|---|
| Less than 20% | 90% |
| 20% to less than 40% | 80% |
| 40% to less than 60% | 60% |
| 60% to less than 80% | 40% |
| 80% to less than 100% | 20% |
At maturity, use the maturity terms rather than extending the last early-withdrawal band. ANZ also specifies a normal $30 administration fee, with an exception following an account holder’s death. These are labelled ANZ terms, not an Australia-wide schedule.
For the worked example, 274 ÷ 365 is about 75.1%, placing it in the 40% reduction band.

Worked example and source figures
| Component | Worked example |
|---|---|
| Principal | $10,000.00 |
| Annual rate and elapsed days | 5%; 274 days |
| Accrued interest | $375.34 |
| Interest reduction | $150.13 |
| Retained interest before fee | $225.21 |
| Separate administration fee | $30.00 |
| Net interest after fee | $195.21 |
| Estimated payout, with no earlier interest payments | $10,195.21 |
The published $225.21 figure is retained interest before the separate fee. Calling it the final cash benefit would overstate this example by $30. The table preserves ANZ’s displayed $150.13 reduction. Applying 40% to the unrounded accrued interest gives $150.14 when independently rounded to cents, while retained interest still rounds to $225.21. The estimator keeps full precision between steps, so its displayed components can differ by a cent from the published illustration or from their displayed sum. Ask for the bank’s settlement quote if a few cents or a boundary date matters.
Use your own numbers without importing another bank’s rules
The estimator’s example inputs are $10,000 principal, a 5% annual rate, a 365-day original term, 274 elapsed days, a 40% interest reduction, a $30 fee and no interest already paid. These defaults reproduce the labelled example; they do not identify the best available deposit or predict your bank’s charge.
Replace the principal, contracted rate and elapsed interest days. Then enter the reduction and fee your bank confirms. The elapsed-term percentage helps you check a published band, but it should not silently impose ANZ’s bands on another provider.
ANZ’s simple daily calculation does not compound interest and excludes the maturity day. A different contract may need a different calculation, so this estimate is not suitable for every interest method. It also models a full withdrawal, not the allocation between withdrawn and remaining balances in a partial withdrawal.
For context, Judo Bank’s explanation of early-withdrawal fees distinguishes administration fees, interest adjustments and notice periods. It supports checking the separate components; it is not a universal fee table or a substitute for your deposit terms.
Reconcile interest already paid before reading the payout
If interest has already reached your transaction account, do not add it again to the amount you expect on closure. A useful reconciliation is:
Estimated closure cash = principal + final retained interest − interest already paid − fee.
For example, suppose the bank confirms final retained interest of $225.21, earlier payments of $300 and a $30 fee. This arithmetic gives $9,895.21 payable on closure. Adding the $300 already received produces $10,195.21 in total cash across both dates.
That example is an accounting reconciliation conditional on the bank confirming those settlement components. It is not a claim that every bank automatically recovers earlier interest from principal. ANZ’s explicit unpaid-interest-first deduction rule cited here concerns partial withdrawals; it must not be generalised into a universal full-closure rule.
A negative remaining interest balance should stay visible in the estimate. Replacing it with zero would hide the difference between money previously received and money still payable. If the calculation suggests a deduction from principal, ask the bank to explain its actual treatment before relying on the payout figure.
Compare early access with waiting, without double-counting
At 5%, the $10,000 example would earn $500 over the full 365-day term on the same simple-interest basis. The difference between that and $195.21 net interest is $304.79. It combines interest not earned after leaving early, the reduction to interest already accrued and the fee.
Do not add that $304.79 to the fee again. It is a comparison with staying until maturity, not an extra debit on your statement. Any return on money after withdrawal, borrowing costs avoided or other benefit of access would be a separate comparison with its own assumptions.
For future deposits, our term deposit maturity ladder guide explains how staggered maturity dates can reduce reliance on breaking one deposit. A ladder does not remove the terms of a deposit you already hold.
Before proceeding, get a written quote showing the release date, accrued interest, reduction, administration fee, treatment of earlier interest payments and final cash amount. Check those lines against the estimate. The practical result is not merely a smaller penalty number: it is knowing how much cash arrives, when it arrives and which assumptions could change it.
