Formula

Borrowing Power=min(Serviceable Loan,DTI Loan)\text{Borrowing Power} = \min(\text{Serviceable Loan}, \text{DTI Loan})

The serviceable loan is calculated from the monthly mortgage payment your budget can support at an assessed interest rate. The DTI threshold loan compares total debt with annual gross income using current New Zealand DTI threshold settings.

Preguntas Frecuentes

Is this bank approval?

No. It estimates a possible borrowing range for planning. A lender or broker must assess your full application.

What DTI threshold is used?

The calculator uses 6x gross income for owner-occupiers and 7x gross income for investors as high-DTI threshold comparisons.

Why include existing debt balance?

DTI compares total debt with gross income, so other debts reduce the loan amount available before crossing the selected threshold.

Why include living costs?

Responsible lending assessments consider whether repayments are affordable after normal living costs and existing commitments.
