KiwiSaver Rate Change 3% to 4% Calculator

This calculator shows what lifting your KiwiSaver contribution from three percent to four percent really costs your weekly pay in New Zealand, and how much extra it could add to your balance by the time you retire. It is a decision worth thinking about carefully, because the contribution rate you choose is one of the few levers fully in your control, and a one percent increase that feels small today compounds into a surprisingly large sum over a working life. The trade-off is simple: the extra one percent comes out of your take-home pay now, in exchange for a bigger nest egg later. You enter your salary, the years until you retire, and the average annual return you expect, and the calculator works out the extra contribution a year, the cost per week from your pay, and the extra amount in your KiwiSaver at retirement once that one percent has compounded over the years. Use it to weigh up whether the weekly cost is worth the long-term gain. Note that your employer is only required to match up to the compulsory minimum, so if you voluntarily go above it, the extra is usually your own contribution. Returns vary and are not guaranteed. This is a projection and general information, not financial advice.
