Growth Projection
Method and scope
The initial balance compounds monthly at the entered nominal annual rate divided by 12. New contributions arrive at the end of each month. The savings-goal tool solves the same model for the monthly contribution, with a zero-rate limit. Taxes, charges and changing rates are excluded. Enter an assumed rate; investment growth is not guaranteed.
Using this calculator in New Zealand
Figures are shown in NZD for New Zealand; selecting another country does not convert an existing investment. Contributions arrive at month end. The entered return is an assumption, not a live local savings rate or a guaranteed investment return. Local tax allowances, account wrappers and charges are not modelled.
Try the starting example
Current balance: $10,000; Target balance: $50,000; Assumed annual return (nominal): 5%; Years to goal: 10.
Monthly saving required: $215.93.
Compare one assumption at a time
A deadline changes the monthly saving required. A longer horizon also gives the assumed growth more time to contribute. If the payment is unaffordable, compare a smaller target or later deadline rather than assuming a higher return will occur. These fictional scenarios use the starting inputs printed above, not your current entries in the interactive calculator.

Have you separated contributions from the return assumption?
The KiwiSaver model separates employee, employer and eligible government contributions, including its stated rate transition. Do not replace those contributions with the assumed investment return. Compare employer amounts after the selected ESCT treatment and check the government eligibility choice before interpreting the balance.
To reproduce the table, reset the calculator, change only the named input and compare the result and any warning. Record the assumptions with your result. See worked planning examples and our calculation and correction process.
