How much can you borrow?

It comes down to two limits: your deposit, and what you can afford to repay. One will max out before the other, and that's what caps how much you can borrow. Once you know which, you can move with confidence knowing your number, or understand exactly what you can do to increase it.

What's inside

What your deposit really lets you borrow

Your deposit isn't just your savings. Add up everything you can use, and most people are closer than they think. You should be aiming for at least 10% of the price, or 5% if you qualify for the First Home Loan, which we explain below.

Places a deposit can come from
  • Your savings
  • Your KiwiSaver
  • A gift from family
  • Equity in a parent's home
A rough figure on the deposit side
Multiply your deposit by 10

With a 10% deposit, $60,000 points to roughly a $600,000 home (the 5% First Home Loan stretches it further).

The 5% First Home Loan

It's a government-backed scheme that lets eligible first home buyers borrow with just a 5% deposit, instead of the usual 10 to 20%. There's no cap on the house price, but there are income limits, the property has to meet certain conditions, and it's only offered through some lenders. It can be a genuine shortcut into your first home, and we work out whether you qualify and whether it's the right move for you.

Why 20% is worth aiming for

Under 20% deposit, banks usually add a low-equity cost (an interest loading or one-off fee). Cross 20% and more opens up: sharper rates, better cashback, and no low-equity cost or extra valuations. You don't have to wait for 20% to buy, and the First Home Loan can often skip the cost, but it's worth knowing what 20% is worth, and we'll tell you when pushing for it pays off.

What you can really afford to repay

It's not just your salary. What you can afford to repay comes down to your income, the fixed costs you already carry, and where interest rates sit. Here's how each one shapes your number.

What can count as income
  • Salary & wages
  • Overtime & allowances
  • Bonuses & commission
  • A partner's income
  • Boarder or flatmate income
  • Self-employed income

Banks count these differently, some take all your overtime, some none. The right lender for your mix can change your number a lot.

Just want a rough figure?
Around 5 times your household income

So $100,000 of before-tax household pay points to roughly $500,000, give or take. Your debts, deposit, lender and today's rates all move it, so it's a starting point, not a promise.

What reduces what you can borrow
  • Fixed loan repayments, like a car or personal loan
  • Student loan repayments
  • Buy-now-pay-later (Afterpay, Laybuy)
  • Credit card limits, the limit, not the balance
  • Childcare and other dependants

Clearing or cutting these is often the fastest way to lift your number.

Why your number moves with interest rates

Banks don't test you at today's rate. They check you could still pay at a higher "stress test" rate. So when rates are low you can borrow more; when they're high, less.

Before you go

A few myths worth busting

"I should wait to apply until my accounts look tidy."
You don't need to. One-off costs like a holiday, or the eating out and nights at the pub you have while you're renting, can all be explained, and the bank can work off what you'll actually spend once you own the place, not your last few months. So a messy-looking account isn't a reason to wait.
"I have to borrow from my own bank."
No. The same situation can be a yes at one bank and a no at another, so the right lender for you can change both your number and your rate.
"Whatever the bank approves is what I should spend."
Their maximum isn't your target. We pressure-test the repayments against your real life, so you borrow a number you're comfortable with, not just the most they'll allow.
