This does not test KiwiSaver withdrawal eligibility, lender approval or a bank's affordability rules.
Planning estimate: This is not KiwiSaver eligibility confirmation, mortgage approval or personalised financial advice.
The target combines a percentage deposit with entered buying costs and a reserve intended to remain after settlement. This avoids treating every available dollar as deposit money.
Compare that target with cash savings, a cautiously entered KiwiSaver withdrawal and other funds that are genuinely available.
The calculator does not decide whether a withdrawal is permitted or how much will be available on settlement day. Check eligibility, timing and balance with official guidance, the provider and lawyer.
Do not enter employer or government contributions that are not part of the withdrawable amount confirmed for the purchase.
The mortgage is purchase price minus the target deposit. LVR is the loan divided by the property value, while the monthly repayment is an unchanged-rate amortising estimate.
Lenders use their own accepted value, verification and serviceability tests, so the result is not an approval amount.
A first-home budget should also allow for rates, insurance, maintenance, utilities and changing mortgage rates. Use the related calculators to test the ongoing household position.
Try a higher interest rate and lower available withdrawal rather than relying on one favourable scenario.
Use property-specific assessments, quotes and professional advice. These sources explain the New Zealand context but do not make the entered assumptions exact.
It compares available cash sources with a target deposit, entered buying costs and a retained reserve. It also estimates the resulting mortgage, LVR and monthly repayment.
No. Enter only the KiwiSaver amount you reasonably expect to withdraw after checking eligibility and the available balance with your provider, lawyer and official guidance.
No. Deposit size is only one part of an application. Lenders assess verified income, expenses, debts, credit history, property security and their own serviceability policy.
Legal work, reports, valuations, moving and other costs normally require cash in addition to the deposit. Separating them helps prevent overstating how much remains for settlement.
No. It is an amortising-loan estimate using the entered rate and term. Actual repayments can differ because of lender calculations, fees, rate changes and loan structure.
