Deposit Gap Calculator

This calculator is built for New Zealanders working out whether they have enough deposit to buy the home they want, and if not, how big the gap is and what closing it would take. You enter the purchase price, the deposit percentage you are targeting, such as the 20% many lenders prefer, your current savings, and any KiwiSaver first home withdrawal you expect to have available. The calculator adds your savings and KiwiSaver to get your available funds, works out the required deposit at your target percentage, and shows the shortfall as a single dollar figure, with a label confirming whether you have reached your target or still have a gap to close. It also breaks down the required deposit, your available funds, and the loan amount you would need with the resulting loan-to-value ratio, so you can see how a bigger or smaller deposit changes your borrowing. Use it to test different price points, deposit targets, or savings scenarios, and to see how a low-deposit loan, more time saving, or a cheaper property would change your position. Because a KiwiSaver withdrawal has its own eligibility rules and a minimum balance requirement, and low-deposit lending can come with conditions and a higher rate, treat the results as a planning estimate rather than a loan approval, and confirm your figures with your KiwiSaver provider and lender.

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.
