Emergency Fund Calculator
Work out how much to set aside for unexpected costs, based on your monthly spending, and how long it takes to save it. Free, no sign-up.
Your Spending and Savings
For a emergency fund, liquidity comes before return — a savings account with the Depositor Compensation Scheme is a common choice.
Your Emergency Fund
Recommended Target (6 months)
$21,000
$3,500/mo × 6 months of cover
💬 In Plain Words
With spending of $3,500/mo, you need $21,000 to cover 6 months of unexpected costs. You have already saved $3,000 — you are $18,000 short. Saving $300/mo you have the full amount in 4 years and 9 months.
Target by Months of Cover
This is a general guideline. Adjust the number of months of cover to how stable your income is. This is not financial advice.
How the Calculator Works
👋 Simple Explanation
A emergency fund is money you set aside for unexpected costs — losing your job, a medical bill, an emergency repair — without having to take on expensive debt. The target is worked out by multiplying your essential monthly spending by the number of months of cover you want.
Target = Essential Monthly Spending × Months of Cover
To know how long it takes to reach the target, the calculator simulates your saving month by month, with an optional return (if you put the money in an instrument that pays one), until you reach the amount.
Why the Depositor Compensation Scheme Matters Here
The Depositor Compensation Scheme, run by the Reserve Bank of New Zealand, has protected deposits with licensed deposit takers up to $100,000 per depositor, per institution, since 1 July 2025. Before then, New Zealand had no deposit guarantee at all. Cover is automatic. For an emergency fund — which by definition has to be safe and reachable — it is wise to keep it with a licensed deposit taker and, if the amount is large, to check you do not exceed the limit at one institution.
Frequently Asked Questions
- How much should I have in an emergency fund?
- A common rule of thumb is between 3 and 6 months of essential spending (not your whole income). If you have irregular income, for example as a self-employed person, a larger fund is wise — 6 to 12 months.
- What counts as 'essential spending' when I work out the fund?
- Rent or mortgage, food, energy, broadband, transport, insurance and the minimum repayments on loans you already have. Spending you control (nights out, hobbies, non-essential purchases) usually does not count, because you can cut or drop it temporarily in a real emergency.
- Where should I keep the emergency fund?
- In a liquid, low-risk account you can reach quickly and without penalty: an on-call savings account. Instruments with more risk, such as shares or KiwiSaver, are not suitable for this fund. Check that the bank is a licensed deposit taker covered by the Depositor Compensation Scheme, which protects deposits up to $100,000 per depositor, per institution, since 1 July 2025.
