This New Zealand calculator helps first-home buyers work out the gap between the deposit they have and the deposit they need for the home they want, and how to close it. You enter the purchase price, the deposit percentage you are aiming for, your current savings, and any KiwiSaver you can withdraw, and the tool calculates the shortfall and what it would take to bridge it. It helps clarify whether a low-deposit loan, more saving, or a different price range is the realistic path. The breakdown shows the required deposit, your available funds including KiwiSaver, and the remaining gap, giving buyers a clear-eyed view of where they stand and what their next move should be.
A KiwiSaver first home withdrawal is subject to the rules, including leaving a minimum balance, so confirm your eligibility. Lower-deposit lending may be available but can come with conditions and a higher rate. Estimate only, not financial advice.
The required deposit is the purchase price times your target deposit percentage. Your available funds are your current savings plus any KiwiSaver you can withdraw. The gap is the difference. The calculator also shows the loan you would need, which is the price minus your deposit, and the loan-to-value ratio that goes with it. A lower target percentage reduces the deposit needed but increases the loan and LVR.
On a $750,000 home with a 20% target, the deposit needed is $150,000. With $60,000 saved and $35,000 of KiwiSaver, you have $95,000, leaving a gap of $55,000. The loan would be $600,000 at an 80% loan-to-value ratio once the full deposit is in place.
