Mortgage calculator
Mortgage repayment calculator: see what a home loan actually costs each payday.
Free and live-updating. Drop in the price, your deposit, an interest rate and a term, and see the weekly, fortnightly and monthly repayment, plus what you'll pay in interest over the life of the loan.
Your loan
Loan amount$700,000
That's an 82% LVR, above 80%, so most banks apply a low-equity premium or margin. Worth a chat about the deposit options.
Fortnightly repayment · 6.50% over 30 years
$2,041
On a $700,000 loan. Over the full term you'd repay $1.59m, of which $892k is interest.
Repayment at each frequency
Weekly$1,020
Fortnightly$2,041
Monthly$4,424
Where your repayments go
Principal (the loan)$700,000
Interest$892,061
Estimates only. Assumes a fixed rate held for the whole term. In reality you re-fix every 1–3 years and the rate changes. Doesn't include fees, insurance, rates or low-equity premiums. Not financial advice; figures are a guide to help you plan.
How this calculator works
What the repayment number includes, and what it doesn't.
This is a standard amortisation calculation. It takes your loan amount (price minus deposit), spreads it over the term you choose, and works out the level repayment that clears the loan exactly by the end, splitting each payment between interest on the balance and principal. Numbers update live as you change the inputs.
What's included
- Repayments at weekly, fortnightly and monthly frequencies, calculated properly for each, not just a monthly figure divided down.
- Total interest and total repaid over the full term, so you can see the real cost of the loan, not just the monthly bite.
- Your loan-to-value ratio (LVR), with a flag when you're above 80% and a low-equity premium is likely.
What's not included
- Rate changes. NZ home loans fix for 1–3 years, not 30. The calculator holds one rate flat so you can compare scenarios, and your actual rate will move at each re-fix.
- Fees and extras: application fees, insurance, council rates, body corporate, and low-equity premiums all sit on top.
- Whether the bank will actually lend it to you. That's servicing and policy, which is what the borrowing calculator and a proper chat are for.
Want the number that counts?
A calculator shows you the maths. What it can't tell you is which structure, term and rate strategy actually fit your situation. That's where a broker saves you real money. We do an initial chat for free.
