My mortgage comes off its fixed rate in two months. I want to know what the payments will be, but I don't want to rush the decision. Where should I start?
You’re in a good position to plan ahead. With your New Zealand mortgage coming off its fixed rate in two months, you have time to work out what your repayments might look like, compare your options, and make a decision without feeling pressured to accept the first rate your bank offers.
I’d start by separating this into two things: what your new repayments could be, and which mortgage option makes the most sense for you.
1. Work out what your repayments could be
Your new repayment will depend mainly on three things:
- Your remaining mortgage balance — how much you’ll still owe when the fixed term ends.
- Your new interest rate — the rate you might refix at, or the floating rate if you don’t immediately refix.
- Your remaining loan term — for example, 20 or 25 years.
You don't need to decide on a new rate yet. Start by calculating repayments at a few different interest rates so you can see the range of possible outcomes.
2. Use a calculator to compare a few rates
A useful starting point is the free Sorted mortgage calculator and guides. You can compare repayments without committing to anything. How to find a good deal on your mortgage » SortedHow to manage your mortgage and pay off your home loan early » Sorted
For example, here’s an illustration of how repayments might change on a 25-year principal-and-interest mortgage.

3. Start talking to your bank, but don't rush to lock in
Over the next few weeks, I’d suggest:
- Ask your bank for options now. Request the rates available for different fixed terms, your estimated repayments, and the date by which you need to make a decision.
- Compare other lenders. Your existing bank isn't necessarily your only option. A mortgage adviser can help compare lenders, but ask about their fees, lender coverage and commission arrangements. How to find a good deal on your mortgage » SortedMortgages and home loans
- Check your flexibility needs. A shorter fixed term, a longer fixed term, or splitting the mortgage into portions may suit different circumstances. Consider whether you might want to make extra repayments or need access to savings.
- Check what happens if you do nothing. Ask whether your loan automatically moves to a floating rate at the end of the fixed term and what that rate would be. Don't assume it will remain on your current rate. Re-fixing your loanHow to manage your mortgage and pay off your home loan early » Sorted
You can use your bank's quoted rates to compare realistic repayment scenarios without making a commitment straight away.

I can help you work out what your repayments might be when your fixed rate ends in December 2026. To get started, what is your approximate remaining mortgage balance?
For example, you could say $450,000. We'll then work through the remaining term and possible interest rates together, one step at a time.
