Do I really need a 20% deposit in NZ?

Not always. The First Home Loan scheme allows 5% deposits for eligible buyers, and most banks have LVR-exempt lending capacity, especially for new builds and certain first home buyers.

Can I use KiwiSaver as part of my deposit?

Yes. After three years of contributing you can withdraw most of your KiwiSaver balance (leaving $1,000) for a first home. It counts towards your deposit alongside cash savings.

What savings rate should I assume?

NZ on-call savings accounts currently sit around 3–5%. Notice-saver or term-deposit accounts pay more (4.5–6%) but lock your money up for longer.

Should I save longer or buy with a smaller deposit?

It depends on house price growth, your rent vs repayment gap and lender pricing. A low-deposit loan can attract a Low Equity Margin (LEM) — an adviser can model whether waiting pays off.

Disclaimer

This calculator provides estimates only based on generic information. Actual savings timeline may vary based on interest rate changes, fees, taxes on interest, and your personal circumstances. A 20% deposit is typically recommended to avoid Lender's Mortgage Insurance (LMI), though some lenders offer options with lower deposits.

Quick answer

This tool projects how quickly you'll reach your deposit goal by combining your current savings, regular contributions and the compound interest your savings earn along the way.

About this calculator

Most NZ banks want a 20% deposit on an existing home — though there are two important exceptions. The First Home Loan scheme (Kāinga Ora) lets eligible buyers purchase with just a 5% deposit, and many banks allocate a portion of their lending to low-deposit ('LVR exemption') applicants, especially for new builds.

The calculator works forwards from where you are today: it takes your starting balance, adds your weekly, fortnightly or monthly contributions, and applies your savings interest rate as monthly compounding. Each month your balance grows from both your contributions and the interest already earned, which is why higher rates and longer time horizons disproportionately accelerate progress.

Remember to budget for more than the deposit: legal fees ($1,500–$2,500), a builder's report ($600–$1,000), LIM ($300–$500) and moving costs. A KiwiSaver first-home withdrawal can supplement your cash savings — model that separately in our KiwiSaver First Home Calculator.

Worked example

Target: $800,000 home with a 20% deposit = $160,000. You have $50,000 saved and contribute $1,000/month into a 4.5% savings account.

With compounding, you'd hit the $160,000 goal in roughly 8 years and 2 months — about 4 months sooner than a non-interest-bearing account, with around $9,000 of that total coming from interest earned.
