First Home calculator assumptions - Fisher Funds Scroll

How this First Home Calculator works


The calculations presented here are based on assumptions about your KiwiSaver account that may differ from your actual behaviour up to and in retirement. These assumptions are listed below.

Neither Fisher Funds nor the Supervisor guarantees the estimates nor accept any liability for any loss or damage of any kind arising out of the use of, or reliance on, the information provided in these estimates including, without limitation, any loss of profit or other damage, direct or consequential.

The estimates are based on the following assumptions:

  Method of calculation

Your estimated balance at purchase date

  • This calculator assumes you are between the age of 18 and 65, and have been a member of KiwiSaver for at least 3 years before your purchase date.
  • Your estimated account balance at purchase date is presented by default in today's dollars (adjusted for inflation) and is based on the level of contributions you enter. It assumes you save continuously on this basis until your selected first home withdrawal date, your investment strategy does not change and you do not make any withdrawals.  $1,000 has been deducted from your estimated account balance at withdrawal date.
  • KiwiSaver savings that originate from an Australian complying superannuation scheme cannot be withdrawn to purchase a first home. This amount should be deducted from your estimated balance at purchase date.
  • The projected returns we've used are based on our assessment of current and likely future economic and investment market conditions. The figures are indicative estimates only and they cannot show the actual or prospective performance of any investment strategy or fund. They do not take into account any additional return that Fisher Funds may add through picking investments that do better than broad market averages.
  • We have also made an allowance for wage/salary increases (if applicable) of 3% per annum over time.


  • This calculator uses a nominal rate of return, and inflation has not been taken into account.


  • If you select that you are employed, your employee and employer contributions increase by 3% per annum until your withdrawal date.
  • If you select that you are employed, the calculator will apply employer's superannuation contribution tax (ESCT) on employer contributions until your withdrawal date.
  • All contributions are assumed to be received halfway through the calendar year.
  • All contributions continue until your withdrawal date.
  • The calculator assumes you are 18 or over and entitled to receive Government annual contribution of 50c for each dollar you contribute, up to a maximum of $521.43 a year (from 1 July to 30 June). We have not allowed for Government contribution in part years.
  • We assumed that you meet all eligibility criteria for the home start grant if you choose to include it. 

Other Investments

  • Your other savings will grow at the rate you have provided (which we have assumed to be after fees and taxes).


  • The following nominal rates of returns per annum (after fees and taxes) are used for the projections.

    Investment Option Rate of Return
    Conservative 2.34%
    Balanced 3.88%
    Growth 5.15%

    The investment options above have suggested minimum timeframes. If you have less than 4 years to go until you intend to purchase your property the calculator assumes that you will be invested in the Conservative Fund and defaults to the conservative rate of return. If you have 4 years to go it defaults to the balanced rate of return, and if you have 5 years or more it defaults to the growth rate of return. You can choose a different rate to the default rate of return if you believe another fund is more suited to your situation.


  • For simplicity, Swedish rounding has been used (numbers have been rounded up or down to the nearest dollar).
