How This KiwiSaver Calculator Works
​
This KiwiSaver calculator estimates future KiwiSaver balances using assumptions around contributions, employer matching, investment growth, inflation, PIR tax, first home withdrawals and retirement withdrawals.
​
Enter your personal situation in the inputs section at the top. In the accumulation section you can adjust for each year your income, contributions, fund type and first home withdrawal. The graph shows real returns until your retirement age, and income adjusted returns to show you the purchasing power of money in today's terms.
​
In the decumulation section enter an annual withdrawal amount in today's terms. This can also be adjusted year by year.
​
Actual KiwiSaver outcomes will vary depending on market performance, your provider, the fund you are invested in, contribution consistency, and future government policy changes.
​
Growth funds may provide higher long-term returns but can also experience larger short-term market fluctuations. Conservative funds generally experience lower volatility but may produce lower long-term growth over time.
​
This calculator is designed as an educational tool only and should not be treated as personalised financial advice.
