How much KiwiSaver could you put toward your first home?
Projects your balance forward to your planned purchase date and checks the withdrawal rules along the way.
Your eligibility
Your KiwiSaver
Growth is net of fees, applied monthly. Markets move — treat this as a planning estimate, not a promise.
Timing
Estimates only, in NZD. Employer contributions are shown before ESCT (the tax deducted from them), so your real balance will be a little lower. Not all KiwiSaver providers or complying funds allow first home withdrawals — check with yours, and confirm eligibility with Kāinga Ora before relying on this.
KiwiSaver First Home Withdrawal Calculator
Buying your first home is one of the biggest financial milestones for many New Zealanders. While saving a deposit can take years, KiwiSaver can significantly reduce the amount you need to save yourself by allowing eligible members to withdraw most of their accumulated balance towards the purchase of their first home.
However, many people aren’t sure whether they qualify, how much they’ll actually be able to withdraw, or how much their KiwiSaver balance could grow before they’re ready to buy.
Our KiwiSaver First Home Withdrawal Calculator helps answer those questions by checking your eligibility under the current withdrawal rules while projecting how your KiwiSaver balance could grow between now and your planned purchase date. It estimates your future balance, calculates government contributions, includes employee and employer contributions, estimates investment growth, and then works out how much you could potentially withdraw while leaving the required minimum balance in your account.
Whether you’re buying your very first home or you’ve received confirmation from Kāinga Ora that you’re eligible as a previous owner, this calculator provides a practical estimate to help you plan your deposit with greater confidence.
What Is the KiwiSaver First Home Withdrawal Calculator?
The KiwiSaver First Home Withdrawal Calculator estimates how much of your KiwiSaver savings you may be able to withdraw towards buying your first home.
Unlike a simple savings calculator, it performs two separate tasks:
- Checks whether you are likely to qualify for a first home withdrawal.
- Projects your KiwiSaver balance up to your planned purchase date.
After estimating your projected balance, the calculator subtracts the mandatory $1,000 that must remain in your KiwiSaver account and displays your estimated withdrawable amount.
The calculator also estimates:
- Future KiwiSaver balance
- Employee contributions
- Employer contributions
- Government contribution
- Investment growth
- Eligibility date
- Estimated withdrawal amount
Why Use This Calculator?
Many home buyers focus only on their current KiwiSaver balance.
In reality, your balance continues growing every payday through:
- Your own contributions
- Employer contributions
- Government contributions (where eligible)
- Investment returns
By estimating these future contributions, you can better understand how much money could be available when you’re ready to purchase your first home.
This helps you:
- Plan your deposit.
- Choose a realistic purchase date.
- Compare different contribution rates.
- Estimate future savings.
- Check your eligibility before applying.
How This Calculator Works
The calculator follows four major steps.
- Check your eligibility.
- Estimate future KiwiSaver contributions.
- Project investment growth.
- Calculate the withdrawable balance.
Each stage updates automatically whenever you change your salary, contribution rate, expected investment return, or planned purchase date.
KiwiSaver First Home Withdrawal Eligibility
Before calculating any withdrawal amount, the calculator first checks whether you satisfy the current first home withdrawal requirements.
To qualify, all four eligibility conditions must be met.
If even one requirement isn’t satisfied, the calculator explains which condition is preventing eligibility.
Rule 1 – At Least Three Years of KiwiSaver Membership
The first requirement is completing at least three years of KiwiSaver membership.
The calculator determines your eligibility by comparing:
- Date you joined KiwiSaver
- Planned purchase date
Formula:
Eligibility Date = Join Date + 3 Years
If your planned purchase occurs before the three-year anniversary, you won’t yet qualify.
For example:
Joined KiwiSaver:
6 August 2022
Eligibility Date:
6 August 2025
Purchase Date:
6 August 2027
Since the purchase date occurs after the three-year anniversary, this condition is satisfied.
Rule 2 – First Home Buyer
The second requirement is that the purchase must be for your first home.
The calculator includes a checkbox asking whether:
“This will be my first home.”
Some previous homeowners may also qualify if Kāinga Ora has confirmed they are in a similar financial position to a first-home buyer.
The calculator reflects this option through the eligibility checkbox.
Rule 3 – You Haven’t Used a KiwiSaver First Home Withdrawal Before
A KiwiSaver first home withdrawal is generally a one-time opportunity.
The calculator checks that you have not previously withdrawn your KiwiSaver savings for a first home purchase.
If you have already used the scheme, you generally won’t qualify for another withdrawal.
Rule 4 – You Intend to Live in the Property
The property must become your principal place of residence.
KiwiSaver withdrawals cannot normally be used to purchase:
- Investment properties
- Rental properties
- Holiday homes
The calculator therefore asks whether you intend to live in the home.
Projecting Your KiwiSaver Balance
Once eligibility has been confirmed, the calculator estimates how your KiwiSaver balance may grow before your planned purchase.
Future growth comes from two sources:
- New contributions.
- Investment returns.
The calculator combines both to estimate your future balance.
Employee Contributions
Employee contributions are calculated using:
Annual Salary × Your Contribution Rate
For example:
Annual Salary:
$80,000
Contribution Rate:
3.5%
Annual Employee Contribution:
80,000 × 3.5%
= $2,800These contributions continue accumulating until your planned purchase date.
Employer Contributions
Employers also contribute to your KiwiSaver account.
The calculator estimates:
Annual Salary × Employer Contribution Rate
Example:
Salary:
$80,000
Employer Rate:
3.5%
Employer Contribution:
80,000 × 3.5%
= $2,800The calculator displays these contributions before Employer Superannuation Contribution Tax (ESCT).
Because ESCT reduces the amount actually credited to your account, the projected balance may be slightly higher than your real balance.
Government Contribution
Eligible KiwiSaver members may also receive an annual Government Contribution.
The calculator estimates this automatically.
The Government Contribution is based on your own contributions during the year.
To receive the maximum contribution, you must contribute at least the required minimum amount during the contribution year and satisfy the applicable eligibility requirements.
The calculator applies the current contribution rules and annual maximum automatically.
If your taxable income exceeds the eligibility threshold reflected in the calculator, the Government Contribution is shown as $0.
Monthly Contributions
Each month, the calculator combines:
- Employee contribution
- Employer contribution
- Government contribution
- Voluntary contributions
These are added to your growing KiwiSaver balance before investment growth is applied.
Investment Growth
Your existing KiwiSaver balance continues earning investment returns throughout the projection period.
The calculator applies your selected expected annual growth rate, compounds it monthly, and adds investment earnings to both your existing balance and your ongoing contributions.
Because investment markets rise and fall, the selected growth rate should be viewed as a planning assumption rather than a guarantee.
Future Balance Projection
Once your eligibility has been confirmed, the calculator estimates how your KiwiSaver balance could grow between today and your planned home purchase.
It considers two sources of growth:
- Regular contributions made throughout the projection period.
- Investment returns earned on both your existing balance and new contributions.
Unlike a basic savings calculator that simply adds deposits together, this calculator applies compound growth, allowing your investment earnings to generate further returns over time.
This provides a more realistic estimate of your future KiwiSaver balance.
How Monthly Growth Is Applied
Every month, the calculator performs the following sequence:
- Adds your employee contribution.
- Adds your employer contribution.
- Adds any voluntary contributions.
- Adds the estimated Government Contribution (where eligible).
- Applies monthly investment growth to the entire balance.
Repeating this process every month produces a projected balance by your planned purchase date.
Because contributions made earlier remain invested for longer, they benefit from additional compound growth compared with contributions made shortly before purchasing your home.
Withdrawable Amount
After projecting your future KiwiSaver balance, the calculator estimates how much you may be able to withdraw.
The calculation is simple.
Formula
Withdrawable Amount = Projected KiwiSaver Balance − $1,000
The remaining $1,000 stays in your KiwiSaver account.
This amount cannot normally be withdrawn because it allows your KiwiSaver membership to remain active after the first home withdrawal.
Why Must $1,000 Stay in Your Account?
Many first-home buyers are surprised that they cannot withdraw their entire KiwiSaver balance.
Under the current rules, the first $1,000 contributed to your KiwiSaver must remain in your account.
This means your withdrawal is usually:
Projected Balance − $1,000
For example:
Projected Balance:
$32,276
Required Balance Remaining:
$1,000
Withdrawable Amount:
32,276
−1,000
--------
31,276This matches the estimate displayed by the calculator.
Government Contribution Explained
One of the biggest advantages of KiwiSaver is the annual Government Contribution available to eligible members.
The calculator estimates this automatically based on your own annual KiwiSaver contributions.
To receive the maximum Government Contribution, you generally need to contribute at least the required minimum amount during the contribution year and satisfy the applicable eligibility requirements.
If your own contributions are lower, the Government Contribution is reduced proportionally.
The calculator also recognises that members above the applicable taxable income threshold are not eligible for the Government Contribution and will display $0 accordingly.
Including this contribution helps produce a more realistic projection of your future balance.
Employer Superannuation Contribution Tax (ESCT)
The calculator estimates employer contributions before Employer Superannuation Contribution Tax (ESCT).
In reality, employers deduct ESCT before the contribution reaches your KiwiSaver account.
This means:
- Actual employer contributions may be slightly lower than the amount displayed.
- The projected balance may therefore be slightly optimistic.
The calculator highlights this limitation so users understand that the projection is intended for planning rather than guaranteeing an exact future balance.
Voluntary Contributions
Many KiwiSaver members choose to make additional voluntary contributions alongside their regular salary deductions.
The calculator includes an Extra Voluntary Contributions field so you can estimate how additional savings may affect your future withdrawal amount.
Examples include:
- Monthly voluntary payments
- Annual lump-sum contributions
- Irregular additional deposits
Increasing voluntary contributions can significantly increase both your projected balance and your eventual withdrawable amount, especially when combined with long-term investment growth.

How to Increase Your Withdrawable Amount
If you’re still saving for your first home, there are several ways to potentially increase the amount available for withdrawal.
Increase Your Contribution Rate
Choosing a higher KiwiSaver contribution percentage means more money is invested each payday, helping your balance grow faster.
Make Voluntary Contributions
Additional one-off or regular voluntary contributions can boost your projected balance beyond compulsory deductions.
Delay Your Purchase
Waiting longer before purchasing allows:
- More employee contributions
- More employer contributions
- Additional Government Contributions (if eligible)
- More time for investment growth
Even delaying your purchase by several months may noticeably increase your balance.
Improve Investment Returns
Selecting a fund that better matches your investment timeframe and risk tolerance may improve long-term growth, although higher returns are never guaranteed.
Always consider professional financial advice before changing funds.
Common Mistakes First Home Buyers Make
Many buyers misunderstand how KiwiSaver withdrawals work.
Common mistakes include:
Assuming the Entire Balance Can Be Withdrawn
At least $1,000 generally remains in your KiwiSaver account.
Forgetting the Three-Year Membership Rule
The eligibility period begins when you joined KiwiSaver, not when contributions first appeared.
Assuming Employer Contributions Are Exact
Employer contributions shown by the calculator are before ESCT.
Actual amounts may be lower.
Expecting Guaranteed Investment Returns
Investment markets fluctuate.
Future growth cannot be predicted with certainty.
Assuming Previous Homeowners Never Qualify
Some previous homeowners may still qualify if Kāinga Ora determines they are in a similar financial position to a first-home buyer.
