Managed Fund vs KiwiSaver Calculator

This calculator compares investing extra money in a managed fund against contributing more to KiwiSaver, weighing KiwiSaver employer and government contributions against the access a managed fund keeps. You enter your figures, and it shows the trade-off between the KiwiSaver boost and the flexibility of money you can reach before 65.

KiwiSaver adds the employer and government contributions you enter, but is locked until 65 or a first home. A managed fund has no such additions but stays accessible. Employer and government amounts depend on your pay and eligibility. Estimate only, not financial advice.

How it works

The calculator grows your monthly contribution at your expected return for both options. For KiwiSaver it also adds the employer contribution each month and the government contribution each year, all compounding. For the managed fund it grows only your own contribution. The KiwiSaver boost is the difference, the value of the contributions you only get inside KiwiSaver, set against the fact that KiwiSaver is locked away.

Worked example

Contributing $400 a month at 6% for 20 years grows a managed fund to around $185,000. Inside KiwiSaver, with a $240 monthly employer contribution and a $521 yearly government contribution added, the balance could reach roughly $300,000, a large boost, but you cannot access it until 65 or a first home.
