Whether you’re saving for a first home deposit, a car, an emergency fund, or a holiday, this calculator tells you exactly how long it will take — and what happens if you increase your monthly contributions.
Saving $100,000 for a house deposit from scratch takes about 6 years at $1,200/month in a 4.5% p.a. savings account. At $2,000/month it takes 4 years. The biggest lever is your monthly contribution — increasing it by $500/month usually saves 1–2 years of saving time. Interest rate matters less than contribution amount for shorter-term goals.

Common NZ Savings Goals — How Long They Take
| Goal | Target | Monthly saving | Rate | Time |
|---|---|---|---|---|
| Emergency fund (3 months expenses) | $15,000 | $500 | 4.5% | 2.4 years |
| Emergency fund (6 months expenses) | $30,000 | $500 | 4.5% | 4.6 years |
| First home deposit (5%, $750k home) | $37,500 | $1,500 | 4.5% | 2.1 years |
| First home deposit (20%, $750k home) | $150,000 | $1,500 | 4.5% | 7.5 years |
| New car | $25,000 | $800 | 4.5% | 2.7 years |
| Holiday | $8,000 | $600 | 4.5% | 1.1 years |

Where to Keep Your Savings While You Build
| Stage | Account type | Why |
|---|---|---|
| Under $5,000 | On-call savings (bonus saver) | Flexibility, earn 4–4.5% |
| $5,000–$20,000 | Bonus saver or notice saver | Better rate, still accessible |
| $20,000+ | Mix: bonus saver + term deposit ladder | Lock in rate on portion, keep some accessible |
For home deposit savings specifically: keep your deposit in a high-rate savings account (not shares) as you get within 2–3 years of purchase. Market falls near purchase could wipe out gains.
KiwiSaver as Part of Your Savings Goal
If you’re saving for a first home, KiwiSaver is an additional savings lever:
- First Home Withdrawal: After 3 years in KiwiSaver, you can withdraw all contributions (yours, employer, and returns) minus $1,000 for a first home
- First Home Loan: 5% deposit if your income and purchase price are within caps (income under $150,000/year, price cap varies by region)
This means your KiwiSaver balance may be part of your deposit. At 3% employee + 3% employer on $60,000 salary = $3,600/year in combined contributions. Over 5 years with returns: roughly $20,000–$25,000 available to withdraw.
Frequently Asked Questions
How long does it take to save for a house deposit in NZ?
A 10% deposit on NZ’s national median price (~$750,000) is $75,000. Saving $1,500/month at 4.5% p.a. takes approximately 4 years. A 20% deposit ($150,000) at the same rate takes 7.5 years. KiwiSaver first home withdrawal can supplement your savings significantly.
What is a realistic savings goal for a New Zealander?
Saving $300–$500/month is achievable for many single-income earners. $1,000–$2,000/month for dual-income households is realistic. The most important thing is to automate savings — treat it as a non-negotiable expense rather than what’s left over.
Should I save in a bank account or invest?
For goals under 3–5 years away: high-interest savings account or term deposit (capital preservation matters). For goals 5+ years away: investing in diversified index funds will likely produce better returns. For KiwiSaver: invest in a growth fund if retirement is 10+ years away.
What is the best savings account for a house deposit in NZ?
Rabobank Online Saver (4.75%), SBS Incentive Saver (4.60%), and Kiwibank Notice Saver (4.50%) are the leading options in April 2026. Bonus savers with no-withdrawal conditions work if you won’t need to touch the money. Keep 1–2 months of expenses in a separately accessible on-call account.
How much should I have saved by 30 in NZ?
As a rough guide: by 30, aim to have 1× your annual salary in KiwiSaver + savings. On a $60,000 salary, that’s $60,000 in combined savings. This is aspirational — many New Zealanders have less. More important is having momentum: consistent monthly contributions, minimal high-interest debt, and a growing KiwiSaver balance.
