Home Deposit Timeline Calculator NZ
This calculator works out how long it will take to save a deposit for your first home in New Zealand, and shows what brings that date forward. You enter your target deposit, how much you already have saved, how much you can put aside each month, the interest rate your savings earn, and any KiwiSaver balance you expect to withdraw under the first home withdrawal rules. From these figures it projects your starting point, made up of savings plus KiwiSaver, how much you still need to save, the interest you are likely to earn as your balance grows, and the total time in years and months until you reach your goal. It adds your monthly contribution and interest to your balance each month until the target is hit, so you can see the effect of saving more, earning a better rate, or adding a KiwiSaver withdrawal. Try lifting your monthly saving to see how many months it shaves off the timeline, or add your KiwiSaver amount to see how much sooner you could get there. If your savings and KiwiSaver already cover the target, the calculator tells you so. Because it relies on the figures you enter and assumes a steady saving pattern and interest rate, treat the result as a planning estimate, and check your KiwiSaver eligibility with your provider before relying on a withdrawal amount.
KiwiSaver first home withdrawal is subject to the rules, including a minimum amount that must be left in the account, so check your eligibility. Interest is applied monthly on your growing balance. Estimate only, not financial advice.
How it works
The calculator starts with your current savings plus any KiwiSaver you can withdraw, then adds your monthly saving each month and applies interest on the balance. It counts the months until the balance reaches your target deposit. Increasing your monthly saving is usually the fastest lever, while interest and a KiwiSaver withdrawal both bring the goal closer. If you already have enough, it tells you that too.
Worked example
With a $120,000 target, $25,000 saved, $30,000 of KiwiSaver available, and $1,500 saved a month at 4% interest, you start at $55,000 and need $65,000 more. That takes about 3 years 1 month, including roughly $10,670 of interest earned along the way, around seven months sooner than the 3 years 8 months it would take with no interest. Lifting the monthly saving shortens it noticeably.
