Property & Mortgage Calculators

Buying, borrowing or investing in New Zealand property — model mortgage repayments and the full amortisation schedule, check how much you can borrow against LVR and DTI limits, work out how long to save a deposit, and assess rental yield and cash flow.

Calculations use monthly compounding (the way NZ banks charge home-loan interest) and reflect Reserve Bank LVR and DTI settings.

Frequently asked questions

How much deposit do I need to buy a house in NZ?
Most banks want a 20% deposit for an owner-occupied home; below that a Low Equity Premium or Margin usually applies. The Mortgage and Deposit Savings calculators help you plan for it.
What is LVR and why does it matter?
Loan-to-Value Ratio is your loan as a percentage of the property value. Above 80% LVR, banks face Reserve Bank lending limits and usually charge a low-equity premium. Use the LVR Calculator to check yours.
