Deciding how to invest

Three things to think about when you're investing:

Risk isn’t bad; it’s a normal part of investing. It’s the chance you take you won’t get the return you expected, or that you might lose some or all of the money you invested.

All investments have different levels of investment risk. Property and shares are generally higher risk than bonds and cash for example.

Higher risk investments have a lot more ups and downs so you’d expect your returns to rise and fall more frequently and in larger amounts. It’s hard to predict how they’ll perform, but if you’re investing for at least 10 years you should end up with a larger amount than if you’d taken less risk.

Lower risk investments have fewer ups and downs over time. But if you invest in lower risk products it’s possible your money won’t grow as fast as inflation. This means your money could be worth less when you eventually spend it. Other investment risks include:

  • Interest rate risk: when interest rates rise after you lock in your money, meaning you don't earn as much on your money as you would have if you'd invested at the higher rate.
  • Liquidity risk: there might not be buyers interested in your investment when you want to sell.
  • Credit risk: the organisation may not be able to repay its debts, and you might lose your money.
  • Economic risk: the economy may or may not be doing well, which could affect the value of your investment.
  • Industry risk: risks affecting a particular industry, like shortages of raw materials or changes in consumer preferences.
  • Currency risk: your investment is affected by changes in the value of the New Zealand dollar.
  • Inflation risk: your investment doesn't earn enough to keep up with inflation.

How to manage risk

Taking on risk is what you’re getting paid for, through investment returns. When you take on more risk, you should get paid more in return. Risk is only bad if:

  • you’ve accepted too much or too little for your investment goal; and/or
  • you’re not being paid enough in return to compensate you for the risk you’ve accepted.

Understanding your investing goals, your attitudes to risk, and then protecting yourself by having more than one type of investment can all help you manage risk.

Return is the money you make on an investment. When choosing investments, you need to consider whether the return is going to be enough to help you reach your goals.

You'll need a bigger return if:

  • Your goal is a large sum
  • You need to achieve your goal in less than 10 years
  • You don’t have much money to start with and/or you don’t plan to contribute regularly.

3 ways you can make money:

  • Interest paid when you invest in fixed interest investments such as bonds or cash deposits. You usually know how much you’re going to be paid and for how long.
  • Dividends paid when you invest in a company’s shares. The amount you’ll be paid will depend on how well the company has performed and the type of shares you own. 
  • Capital gain made when you sell an investment for more than you paid for it. 

Investments aren’t free, even if you invest directly. Any fees you pay reduce the return you make, so you should understand them before you invest.

Types of fees 

Our ways to invest pages explain the fees associated with specific types of investments.

If you’re using a financial adviser or broker, they may also charge you a fee for their services. See paying for advice.

How fees stop your money growing

Only pay higher fees if you’re confident you’ll be persistently rewarded with returns high enough to make it more financially worthwhile than an investment with lower fees.

For example, if you were confident that by paying the higher 1.25% fee, you’d make a 7% return on your $10,000 investment, it would be worthwhile. This is because your return after fees would be higher than if you’d paid lower fees and achieved a 6% return.

Things to remember

  • Fees are usually shown in percentages.
  • Small percentage differences can mask how much impact fees have in actual dollar terms.
  • Use an online calculator, or ask your provider to help you work out your potential net returns in dollars.

Financial advice can help you identify what you need, what’s right for you, and make sure you’re aware of the risks of certain investments or different types of insurance protection.  This is all about helping to set yourself up for the future. See our Getting financial advice page for more information. Read  more about getting advice.

Spotlight on: Compound interest

The story goes that Albert Einstein once called compound interest the eighth wonder of the world, saying “He who understands it, earns it; he who doesn't, pays it”.

Whether or not those are actually his words, it’s true that compound interest is a powerful effect of investing that, over time, will get your money working for you.
