About this calculator

The rates of return are after fees, before tax. Tax on investment returns (PIR) is calculated based on your income using the thresholds effective 1 April 2025: ≤$15,600 = 10.5%, ≤$53,500 = 17.5%, above $53,500 = 28%.
Employer contributions are reduced by ESCT (Employer Superannuation Contribution Tax) before being credited to your KiwiSaver. Thresholds (effective 1 April 2025) are based on prior-year salary + employer super contributions: ≤$16,800 = 10.5%, ≤$64,200 = 17.5%, ≤$93,720 = 30%, ≤$216,000 = 33%, above $216,000 = 39%.
In retirement, the PIR applied to investment returns is based on the "Other taxable income in retirement" you enter (e.g. NZ Super, rental, dividends). KiwiSaver withdrawals themselves are not taxable income.
The fees used are an average for the fund type and will not reflect the actual fees you will pay.
The returns sourced in this calculator are sourced from the latest Morningstar KiwiSaver report for a 10 year period ending March 2026. Returns and the period-end date can be updated in the Fund type return assumptions table below.
The government contribution (member tax credit) is calculated at 25 cents per dollar of employee and voluntary contributions, up to a maximum of $260.72 per year (effective 1 July 2025). It applies from age 16 and ends in the year you turn 65 (last full year of eligibility is age 64). Members earning over $180,000 are not eligible. Employer contributions do not count toward the threshold.
