Building a realistic savings plan means understanding your current position and creating actionable steps to reach your goal.
Step 1: Calculate Your Target Deposit Determine your target property price range, the deposit percentage you need (10-20%), and additional costs like legal fees, building inspections, and moving expenses. Add 10-15% buffer for these costs.
Step 2: Assess Your Current Position Calculate your current savings and KiwiSaver balance. Review your spending for the past 3 months to understand your actual monthly surplus or deficit. Be honest about your realistic timeline to purchase.
Step 3: Set Your Monthly Savings Target Bridge the gap between your current position and goal. Divide the required amount by months until your target purchase date. Build in a buffer for unexpected expenses or market changes.
Step 4: Choose Your Strategies Start with the highest-impact strategies for your situation. If you're already frugal, focus on income generation. If you earn well but spend freely, focus on expense reduction.
Step 5: Automate Everything Possible Set up automatic transfers to savings accounts on payday. Automate KiwiSaver contribution increases. Remove manual decision-making from the savings process.
Step 6: Track and Adjust Monthly Review your progress every month. Celebrate milestones. Adjust your strategies if life circumstances change. Recommit to your goal regularly.
Scenario: Couple targeting $750,000 property with 10% deposit
| Savings Source | Year 1 | Year 2 | Year 3 | Total |
|---|---|---|---|---|
| KiwiSaver (both) | $16,400 | $17,300 | $18,200 | $51,900 |
| Monthly Savings ($1,800) | $21,600 | $21,600 | $21,600 | $64,800 |
| First Home Grant | - | - | $10,000 | $10,000 |
| Side Income | $6,000 | $8,000 | $10,000 | $24,000 |
| Interest Earned | $400 | $1,200 | $2,100 | $3,700 |
| Annual Total | $44,400 | $48,100 | $61,900 | $154,400 |
Result: This couple exceeds their $75,000 target in under 2 years, giving them options for a larger deposit or purchasing sooner.
It varies significantly based on income and deposit size. Typical timeframes are 3–5 years for first-home buyers saving 10–20% deposits, though it can be faster with high incomes or living at home.
Generally, eliminate high-interest debt first (credit cards, personal loans), then save for your deposit while maintaining minimum payments on lower-interest debt like student loans.
Aim for 20–30% of your after-tax income. On a $70,000 salary (~$55,000 after tax), that's $900–$1,400/month.
Yes, genuine gifts are acceptable to banks. Document the gift properly and show it's been in your account for at least 3 months before applying for a loan.
Both are important. KiwiSaver gets you free money (employer and government contributions) but can only be accessed for a first home. Balance both approaches.
The fastest approach combines multiple strategies: maximize KiwiSaver contributions, significantly reduce housing costs (move home), generate additional income through side hustles, and cut discretionary spending. This combination can reduce saving time by 50% or more.
If prices rise faster than you can save, consider whether a lower deposit option (10% vs 20%) makes sense despite higher costs. Sometimes entering the market sooner is financially better than waiting.
Keep 3–6 months of expenses separate from your house deposit savings. This prevents you from raiding your deposit fund for unexpected costs and shows banks you have financial discipline.
