KiwSaver Calculator Methodology:

For each period (month), the following components of the calculation are taken into consideration:
- the fund types available for this KiwiSaver and their respective expected return on investment rates are as follows: Cash 1.00%, Conservative 2.50%, Balanced 4.00% and Growth 7.00%.
- the specific return on investment rate by month is used in each calculation to adjust for the ability for the user to change the fund at any age.
- the specific salary and the expected increase is used in each calculation. This is adjusted after every year to the new salary as expected by the user.
- the compounding of the respective investment gains occurs at the month level, as seen in the month by month KiwiSaver balance schedule.

a. The opening balance of the month, which contributes to the previous balance calculations for the compound interest investment gains and investment tax to provide the previous balance adjustment moving forward.
b. The employment additions, which relates to the employee and employer contributions. Tax is then applied to the employer contribution value only before the net add from the employment addition is calculated. From there, the month specific investment gains and investment tax are calculated to provide the KiwiSaver contribution balance moving forward.
c. The employee additional contribution, which relates to the optional regular top-up from the user. From the per period addition the month specific investment gains and investment tax are calculated to provide the additional contribution balance moving forward.
d. The government contribution, which is a $521.43 bonus to accounts that contribute to the required threshold every 12 months. From the per period addition, of which 11 out of 12 months is zero, the month specific investment gains and investment tax are calculated to provide the Government contribution balance moving forward.
e. The account fees as declared are removed for every period.
f. The first home buyer reset trigger is applied if the month is assigned as the period of a balance change for the first home purchase. This resets to the balance to $1,000.

The formula for calculating the balance at the end of each respective period throughout the saving scheme is:
- If not a flagged period for first home buyer reset: (a. previous period balance + investment gains) + (b. employment contribution for period) + (c. employee additional contribution for period) + (d. government contribution for period [if any]) - (e. account fees for period)
- If a flagged period for first home buyer reset: (a. previous period balance reset to $1000 + investment gains) + (b. employment contribution for period) + (c. employee additional contribution for period) + (d. government contribution for period [if any]) - (e. account fees for period)
