Figures are shown in today's dollars: growth and salary are projected in nominal terms, then converted back using a 2% inflation assumption, matching FMA methodology.
NZ Superannuation is only added from age 65. If you plan to retire earlier, the years before 65 show savings-only income.

Life expectancy at 65 in NZ is around 85-87. Plan longer for safety.

How this calculator works
The calculator runs your numbers through two phases. The accumulation phase grows your KiwiSaver and other savings from now until your retirement age, using nominal salary growth, your contribution rate and chosen fund type. The result is then converted to today's dollars using a 2% inflation assumption. The drawdown phase works out the maximum sustainable weekly withdrawal in today's dollars so your savings last to your nominated age. NZ Super is added on top only from age 65 onward.
Growth during working years uses FMA-aligned nominal returns, net of fees and 28% PIR: Conservative 2.5%, Balanced 3.5%, Growth 4.5%, Aggressive 5.5%.
Salary is assumed to grow 3.5% a year nominally, the FMA's standard projection assumption, with contributions rising in line.
A 2% annual inflation assumption converts the projected nominal lump sum and drawdown income back into today's purchasing power.
During retirement, savings are assumed to earn a nominal 2.5% net of fees and tax, converted to a real rate of roughly 0.5% for the drawdown calculation.
Employer KiwiSaver contribution is 3.5% of gross salary (the compulsory minimum from 1 April 2026), shown before Employer Superannuation Contribution Tax (ESCT), which reduces the amount that actually reaches your account.
Government KiwiSaver contribution is 25 cents per dollar you contribute, up to $260.72 a year, requiring at least $1,042.86 of your own contributions, for members under 65 earning $180,000 or less.
NZ Superannuation rates used are effective 1 April 2026 (M tax code): single living alone $555/wk, single sharing $512/wk, couple (combined) $854/wk — and only applied from age 65.
If "Couple" is selected, all figures should be entered as combined household amounts. This calculator doesn't yet model two individual incomes, balances or contribution rates separately.
What this calculator doesn't model: Employer Superannuation Contribution Tax on the employer contribution, a partner who is older or younger with separate KiwiSaver settings, overseas pensions reducing NZ Super, healthcare costs above average, downsizing the family home, or part-time work in retirement. Past performance is not a guarantee of future returns. This tool is illustrative only and not financial advice.
