Breaking a term deposit before its maturity date is possible, but it comes at a cost. Here’s what the penalty actually is, when it makes sense to break, and when you’re better off waiting.
Breaking a term deposit early typically costs you 1–3 months of interest — not the full interest earned. If you've held it for more than 3 months, you'll likely still receive some interest. Most banks allow early withdrawal with notice (usually 31 days). Calculate the break cost vs the benefit of the funds before deciding.
What Is the Break Cost?
NZ banks structure early withdrawal penalties as a partial interest reduction, not a fee charged on top. The most common structure:
| Time held | Break penalty |
|---|---|
| Under 1 month | No interest paid at all |
| 1–3 months | 1 month’s interest forfeited |
| 3–6 months | 2 months’ interest forfeited |
| Over 6 months | 3 months’ interest forfeited |
Policies vary by bank — always confirm with your specific institution before breaking.
Example: $20,000 term deposit, 12-month term at 4.5%, broken at month 8
- Full interest earned to date: $20,000 × 4.5% × (8/12) = $600
- Break penalty (3 months interest): $20,000 × 4.5% × (3/12) = $225
- Net interest received: $375
You still receive some interest ($375), just not the full amount you would have earned by completing the term ($900).
When Breaking a Term Deposit Makes Sense
1. Emergency cash need
If you need funds immediately for a genuine emergency (medical, urgent repair, job loss), breaking the term deposit is often the right call. The interest penalty is small relative to the cost of using a high-interest credit card or personal loan.
Compare: 3 months interest penalty at 4.5% on $20,000 = $225. Credit card interest at 20% for 3 months on $20,000 = $1,000. Breaking the term deposit is clearly better.
2. Interest rates have risen significantly
If you locked in a term deposit at 4.0% and rates have risen to 6.0%, reinvesting at the higher rate may offset the break cost.
Break-even calculation:
- Break cost: 3 months interest at old rate
- Gain from new rate: (new rate − old rate) × remaining term
- If gain > break cost: consider breaking
Example: $50,000 deposit, 4.0% rate, 9 months remaining, new rate 6.0%
- Break cost: $50,000 × 4.0% × (3/12) = $500
- Rate gain over 9 months: $50,000 × 2.0% × (9/12) = $750
- Net benefit: $750 − $500 = $250 gain from breaking
Worth doing in this case. If the rate difference were smaller (4.0% → 4.5%), the break-even would not be met.
3. Better investment opportunity
If you identify a significantly better investment (e.g., a property opportunity, or you want to deploy into a sharply lower share market), breaking a term deposit may be worthwhile. Calculate the break cost and compare to the expected benefit of the alternative investment.
When Breaking a Term Deposit Is NOT Worth It
Short remaining term: If you only have 3–4 weeks left, the break penalty often exceeds the interest you’d earn in that remaining period. Wait it out.
Marginal rate difference: A 0.2%–0.3% difference in rates rarely justifies a break penalty — the math usually doesn’t work.
Market timing: Breaking a term deposit to invest in shares because “the market looks cheap” is speculative. Don’t break predictable fixed-income investments to time variable markets.
How to Break a Term Deposit in NZ
Step 1: Check your bank’s policy
Call your bank or check online. Most NZ banks require:
- Written notice or a form to be completed
- 31 days’ advance notice (some allow immediate break for genuine hardship)
- Confirmation of the break cost calculation
Step 2: Calculate the break cost
Ask the bank for the exact calculation before committing. Don’t rely on estimates.
Step 3: Request the break
Submit the request in writing (email or secure message via online banking). Confirm the funds will transfer to your nominated account on maturity of the notice period.
How to Avoid Needing to Break a Term Deposit
The best solution is prevention. A term deposit ladder (splitting your deposit across multiple terms) means you have funds maturing regularly — reducing the chance of needing to break any single deposit.

Also: always maintain a separate savings account emergency fund that you don’t need to break a term deposit to access.
