Rent vs Buy Calculator

The Property

Enter the details of the property you are considering buying.
$
NZ national median is around $795,000. Auckland sits around $1,015,000. Enter the price of the home you have in mind.
20%
Most NZ buyers use 20%. First home buyers can use KiwiSaver and the First Home Grant for deposits as low as 5-10%, but this increases your mortgage and repayments.
$
Covers legal fees, LIM report, building inspection, and loan setup. Budget $10,000-$20,000 for a typical NZ purchase.

Renting Costs

Enter what you are currently paying in rent, or the rent you would pay instead of buying.
$/week
NZ national average is $627/week (2025). Auckland averages $686/week. Check Trade Me or Realestate.co.nz for your area.
3%
NZ rents have increased ~4-5%/year historically, though 2025 saw a slight drop. Use 3% as a conservative estimate.

Your Mortgage

Enter your expected mortgage terms. Check your bank or use a mortgage broker to get current rates.
%
NZ average 1-year fixed rate is around 4.82% (Apr 2026). Special rates with 20%+ deposit can be as low as 4.39%.
30years
Most NZ home loans run for 25-30 years. A shorter term means higher repayments but less interest paid overall.

Annual Ownership Costs

These are the ongoing costs of owning the property on top of your mortgage.
$
Check rates.nz or your local council website. NZ average is around $2,500-$4,000/year depending on region and property value.
$
Typical NZ home insurance runs $1,200-$2,000/year. Get a quote from your insurer for accuracy.
1% of house value
Rule of thumb: budget 1% of your home's value per year for repairs and upkeep. New homes may be less (0.5%), older homes more (1.5-2%).

Growth Assumptions

These assumptions affect the long-term comparison. Adjust to match your expectations.
4%
NZ long-term average is around 5-6%/year, though it varies hugely by region and period. 3-4% is a conservative estimate for the current market.
6%
If you rent instead of buy, your deposit could be invested. NZ index funds have historically returned 7-9%/year. Use 6% as a conservative after-tax estimate.
10years
How many years to compare. The longer the period, the more buying typically benefits from capital growth. 10 years is a common benchmark.
