In New Zealand property investment, capital growth builds your wealth, but cash flow pays the bills.
It is easy to get caught up in the excitement of a potential purchase, but before you sign a sale and purchase agreement, you need to strip the emotion away and run the hard math. Will the weekly rent actually cover your mortgage, the council rates, and the property manager? Or will this property drain your personal bank account every single week?
Our tool below features a dual-function setup depending on where you are in your property hunt:
- Standard Mode: Input the purchase price and expected rent to instantly calculate your gross and net rental yield.
- Reverse Mode: Have a specific target in mind? Toggle the calculator to enter your desired yield and projected weekly rent, and the tool will automatically tell you the maximum purchase price you should pay for the property.
Gross Yield vs. Net Yield: Don't Get Caught Out
When real estate agents market an investment property, they almost exclusively advertise the Gross Yield. You need to know the difference before making an offer.
- Gross Yield (The Vanity Metric): This is simply the total annual rent divided by the purchase price. It looks great on a flyer, but it completely ignores the reality of owning a house. It assumes you have zero expenses.
- Net Yield (The Reality Check): This is your true cash flow. Net yield subtracts all your holding costs—council rates, insurance, property management fees, maintenance, and body corporate levies—before dividing the remainder by the purchase price.
If a property has a high gross yield but massive body corporate fees, your net yield will crash. Always make your buying decisions based on the net figures.
