Mortgage Repayment Calculator NZ

This NZ mortgage repayment calculator estimates repayments from a loan amount, annual interest rate, loan term, and payment frequency. It uses a standard amortising loan formula, divides the annual rate into the selected payment frequency, and applies it across the full term.

It is useful after a deposit and buying-cost check, because repayment pressure can look different from the headline purchase price. General information only. Estimate only. Results depend on user inputs.

A $650,000 loan over 30 years at 6.75% will show a different payment amount depending on whether you choose weekly, fortnightly, or monthly repayments.

A buyer comparing homes could run several loan amounts, then use the rent vs buy calculator to compare estimated ownership cash flow with current rent.

• Uses a standard amortising loan formula with a fixed rate for the whole term.
• Does not include fees, changing rates, offset accounts, redraw, or lender-specific rounding.
• Payment frequency changes the period used for the estimate.

This calculator does not include lender fees, changing interest rates, fixed-rate rollovers, offset accounts, redraw, revolving credit, repayment holidays, default interest, income testing, credit assessment, or lender-specific rounding.

It does not imply lending approval, affordability, serviceability, or a particular mortgage product. Not legal, financial, tax, valuation, mortgage, insurance, investment, property, lending, or compliance advice.

The estimate comes from a transparent client-side amortisation formula and user-entered figures. Compare outputs with current lender repayment calculators, loan documents, mortgage adviser guidance, and bank approval conditions before relying on them.

Use the buyer property planning workflow to connect repayments with deposit, buying costs, LVR, and DTI checks.
