NZ KiwiSaver First Home Calculator
Project your KiwiSaver balance at your planned purchase date, estimate your withdrawal amount, and see how contribution rate, employer contributions, and fund type affect your deposit. All figures in NZD.
Your contribution rate is the single biggest lever you control. See how 3%, 6%, and 10% contributions compare over 5 years at your current salary.
| Contribution Rate | Your Contrib/yr | Projected Balance | Withdrawal |
|---|---|---|---|
| 3% | NZ$2,250 | NZ$46,888 | NZ$45,888 |
| 6% | NZ$4,500 | NZ$59,321 | NZ$58,321 |
| 10% | NZ$7,500 | NZ$75,898 | NZ$74,898 |
After 12 months in KiwiSaver you can take a contribution savings suspension (holiday) for up to 3 years at a time. This stops both your and your employer's contributions.

| Eligibility | Must have been contributing for at least 12 months |
| Duration | Apply for 3 months to 3 years at a time; can renew |
| Employer contributions | Employer contributions also stop during the holiday |
| Government contributions | Government $521/yr contribution also stops |
| Balance | Your existing balance keeps growing (if invested in growth fund) |
| How to apply | Submit a Savings Suspension form to IRD (ir1022) |
How to Use This NZ KiwiSaver First Home Calculator
Enter your current KiwiSaver balance, annual salary, contribution rate, employer rate, and years until purchase. The calculator projects your balance at purchase date, estimates your withdrawal amount (balance minus the required $1,000), and shows total employer and government contributions you will accumulate.
Use the Advanced section to compare what different contribution rates (3%, 6%, 10%) mean for your final balance — this is the most powerful lever you control. The fund type comparison shows how conservative, balanced, and growth fund returns affect your projected balance over your timeline.
The Formula
Annual Contributions = Employee Contrib + Employer Contrib + Government Contrib
Employee Contrib = Salary × Employee Rate
Employer Contrib = Salary × Employer Rate (min 3%)
Government Contrib = min(Employee Contrib × 0.5, $521.43/yr)
Withdrawal Amount = Projected Balance − $1,000
The government contributes 50 cents per dollar you contribute, up to $521.43 per year. To receive the full government contribution, you must contribute at least $1,042.86 per year to your KiwiSaver. For a person on $75,000 salary, a 2% contribution rate ($1,500/yr) easily exceeds this threshold.
Example
Priya: 5 Years to First Home Purchase
Priya earns $80,000/yr, has $18,000 in KiwiSaver, contributes at 4%, employer contributes 3%, and chooses a balanced fund (est. 5% return).
| Starting Balance | $18,000 |
| Employee Contribution/yr | $3,200 (4%) |
| Employer Contribution/yr | $2,400 (3%) |
| Government Contribution/yr | $521 (full — she contributes over $1,042) |
| Fund Return (est.) | 5% per annum (balanced) |
| Projected Balance at Year 5 | ~$53,100 |
| Withdrawal Amount | ~$52,100 (balance minus $1,000) |
If Priya switched to 6% contribution, her balance would reach ~$57,800, adding ~$4,700 to her deposit — a meaningful boost for a first home.
KiwiSaver First Home Withdrawal Rules
- 3-year minimum: You must have been a KiwiSaver member (contributing or suspended) for at least 3 years
- Amount: You can withdraw your full balance minus $1,000 that must remain in the account
- First home only: Property must be in New Zealand and you must be buying your first home, or be in a no-better financial position than a first home buyer
- Apply early: Contact your KiwiSaver provider at least 10–15 working days before settlement
- Statutory declaration: You must sign a declaration within 12 months of IRD approving the withdrawal
- No income cap: Unlike the First Home Grant, there is no income test for the KiwiSaver withdrawal itself
Maximising Your KiwiSaver for a First Home
The three strategies that make the biggest difference are:
- Increase your contribution rate — even moving from 3% to 4% adds thousands over 5+ years. Going to 6% or higher is the fastest way to build your balance.
- Maximise the government contribution — make sure you contribute at least $1,042/yr to receive the full $521 government match. On most salaries, even the 3% minimum exceeds this easily.
- Choose the right fund — for a 5+ year timeframe, a balanced or growth fund will typically outperform conservative. Switch to conservative 2–3 years before you plan to buy to lock in gains and protect against market drops.
