How rent vs buy comparison works

Compares total cost of renting vs buying over a chosen period — including rent increases, mortgage interest, rates, maintenance, and capital growth.

  1. 1

    Total rental cost

    Rent_total = annual_rent × years × (1 + rent_increase_%)^years

    Compound rent rises (3-5%/yr typical in NZ).

  2. 2

    Buying costs

    Buy_costs = deposit + total_interest + rates + insurance + maintenance + selling_costs

    Maintenance ~1%/yr. Selling ~3% commission + legal.

  3. 3

    Property value growth

    Future_value = purchase_price × (1 + capital_growth_%)^years

    NZ long-term avg 5-6%/yr.

  4. 4

    Net buying cost

    Net_buy = buy_costs − (future_value − loan_balance)

    Equity reduces effective cost.

  5. 5

    Break-even point

    Break_even = years where buy_cost = rent_cost

    NZ typically 7-10 years.

Worked example

Inputs: $700k property, 20% deposit, $580/wk rent, 10 years

Result: Rent: ~$370k. Buy net: ~$280k. Buy wins by ~$90k.

Frequently Asked Questions

Is it cheaper to rent or buy in NZ?
In New Zealand's current market (2025), the answer depends heavily on your location, available deposit, and time horizon. In most major centres, the weekly cost of servicing a mortgage at 80% LVR on a median-priced home exceeds weekly rent for an equivalent property. For example, in Auckland a median home at $1,000,000 with 20% deposit ($200,000) and a 6.5% mortgage rate would cost around $1,200 per week in interest and principal, while a comparable rental might be $700–$800 per week. However, buying builds equity over time and provides protection from rent increases and landlord evictions. Over a 30-year horizon, buyers in most NZ cities have historically outperformed renters financially, partly due to capital gains. The comparison changes significantly depending on deposit size, rental yield, and whether you factor in opportunity cost.

How do I compare the true cost of renting vs buying?
To properly compare renting versus buying in New Zealand, you need to account for all costs on both sides. For buying: mortgage repayments, rates (council and water), insurance, maintenance (typically 1–2% of property value p.a.), body corporate fees (for apartments), and legal/valuation costs at purchase. For renting: rent payments, contents insurance, and any bond costs. You should also consider opportunity cost — the return you could earn by investing your deposit elsewhere (e.g., in term deposits or KiwiSaver). On the buying side, capital gains and equity build-up are important benefits. A realistic comparison typically spans 10 years or more. Tools like the Sorted rent-vs-buy calculator account for these factors. As a rough guide, if your price-to-rent ratio (property price divided by annual rent) exceeds 25–30x, renting is often financially competitive with buying in the short to medium term.

What hidden costs come with buying a home in NZ?
When buying a home in New Zealand, many costs beyond the purchase price and mortgage are often overlooked. One-off purchase costs include: solicitor/conveyancing fees ($1,500–$3,000), LIM report from the council ($300–$400), building inspection ($500–$1,000), valuation ($700–$1,200), and mortgage registration fees. Ongoing ownership costs include: council rates (averaging $2,500–$4,500/year depending on region and property value), water rates, building insurance ($1,200–$3,000/year), and maintenance (budget 1–2% of property value annually — a $600,000 home may need $6,000–$12,000 in maintenance each year). Body corporate levies for apartments can range from $3,000 to $15,000+ per year. Unexpected repairs — roof replacement ($15,000–$25,000), re-piping ($20,000+), or weathertight remediation — can be very costly. Budget for these before committing to purchase.

How does the NZ property market affect the rent vs buy decision?
New Zealand has one of the most expensive housing markets in the world relative to income, with a national price-to-income ratio consistently above 8x (Auckland above 10x). This makes the rent-vs-buy decision particularly complex. When house prices are rising strongly (as in 2020–2021), buying quickly builds equity and capital gains can dwarf mortgage costs. When prices are flat or falling (as in 2022–2024), renters avoid capital losses and the high cost of ownership. The RBNZ's OCR changes directly affect floating mortgage rates and influence fixed rates, making repayment costs volatile. Rental markets are also tight in most NZ cities, with vacancy rates often below 2% and annual rent increases common. In this environment, both renters and buyers face significant financial pressure. The decision is highly personal and should consider job security, family plans, geographic flexibility, and long-term financial goals.

The rent-vs-buy calculator compares the total financial cost of renting versus buying a home in New Zealand over a chosen time horizon. It accounts for mortgage interest, property rates, insurance, maintenance, equity accumulation, and the opportunity cost of the deposit (what the deposit money could earn if invested instead).

How this calculator works

Buying costs over the period include: mortgage repayments (P&I), property rates (~1.0% of value per year), home insurance (~0.3%–0.5% of value per year), and maintenance (~1% of value per year), less the equity built up in the home. Renting costs include rent payments and foregone investment returns on the deposit. The opportunity cost of the deposit is calculated by assuming the deposit could earn a market return (e.g. 5–7% p.a.) in a diversified portfolio. The break-even point is typically 7–12 years in NZ depending on city and interest rate environment.

Worked Examples

$800,000 house, 20% deposit ($160,000), 30-year mortgage at 7%, vs renting at $2,800/month

Monthly mortgage repayment ~$4,262. Monthly renting cost $2,800. Buying costs more monthly short-term but builds equity long-term.

  1. Loan amount: $800,000 − $160,000 = $640,000
  2. Monthly P&I repayment at 7% over 30 years: ~$4,262
  3. Annual property rates (1%): $8,000 / 12 = $667/month
  4. Annual maintenance (1%): $8,000 / 12 = $667/month
  5. Total monthly buying cost (excl. equity gain): ~$5,596
  6. Monthly renting cost: $2,800
  7. Monthly cost difference (buying vs renting): +$2,796
  8. But buying builds ~$640,000 equity over 30 years (before capital gains)
  9. Opportunity cost of $160k deposit at 6% p.a.: ~$9,600/year or $800/month
  10. Break-even depends heavily on future house price growth vs investment returns
