Borrowing Capacity Calculator NZ 2026

This borrowing capacity calculator estimates how much you could borrow for a home loan in New Zealand, based on your deposit, expected interest rate, preferred loan term and the repayment you could comfortably afford each week, fortnight or month. Enter your deposit, the interest rate as a percentage, the loan term in years, and the repayment you could manage, and the calculator works backwards from that figure to estimate the property price a lender could theoretically fund. Because a slightly bigger budget can unlock more borrowing power than expected, it also returns three extra results alongside your main figure, showing the property price you could afford if you paid 5%, 10% or 15% more than your chosen repayment. This lets you see how much stretching your budget changes what you could buy. Use it to set a realistic house-hunting budget, test how sensitive your borrowing power is to rate changes, or weigh up whether a higher repayment is worth the risk. Keep in mind that real lenders also test your ability to repay at a higher stressed rate, often around 8 to 9%, and apply debt-to-income and loan-to-value limits, so your actual approval may be lower than shown here. Being conservative with the repayment figure you enter gives a more realistic result. These figures are indicative estimates only, not a substitute for advice from a lender or mortgage adviser.
