Useful mortgage calculators for New Zealand borrowers.

These tools give you a starting point, not a final answer. Every situation has variables a calculator can't account for. If the numbers raise questions, that's exactly what we're here for.

Could I save by refinancing?

Compare your current rate against a new rate to estimate monthly savings and how quickly you'd break even.

If the numbers look interesting, let's talk.
Talk to an adviser

This calculator is a guide only, based on a fixed rate held for the full remaining term and a like-for-like principal and interest structure. It assumes constant rates and does not account for break fees, cashback offers, or a lender's specific terms. Talk to us for advice specific to your situation.

Why people choose The Loan Supply Co.

  • We work for you, not the bank

    We're paid by lenders on settlement, which means our advice is always focused on what's right for your situation, not which lender pays the most.

  • More lenders, more options

    We have access to major banks and non-bank lenders across New Zealand. More options means a better chance of finding the right fit.

  • One adviser, start to finish

    You deal with one person throughout. No handoffs, no repeating yourself, no starting over.

  • Complex situations welcome

    Tricky income, self-employed, or a situation that doesn't fit the standard criteria. That's where we're most useful.

Not sure what the numbers mean for you?

That's what we're here for. A quick conversation costs nothing and gives you a clear picture of where you stand.
