When your KiwiSaver (or any investment) makes a return, those returns start ‘also’ making returns. This is known as compound interest or more specifically compounding returns.

To make the most of compounding returns, the sooner you start, the better off you will be. Let’s compare two friends Blake and Barnaby.

Blake, aged 15 starts doing holiday work on the family farm. She manages to save $5,000 each year for ten years into a managed fund (like Pathfinders). Along the way she receives an average return of 10% per year including all dividends that are reinvested. And she stops contributing annually after ten years but holds the investment until she is 65.

Barnaby waits until he gets a full-time job before he starts investing at age 25. Like Blake, he puts in $5,000 a year, but unlike Blake, he doesn’t stop. He keeps on investing $5000 every year until he’s 65 years old (also reinvesting his dividends).

All up, Blake put in $50,000. Barnaby puts in $200,000. Question: Who do you think has more money?

Answer: Even though Blake put a quarter of the money, her investment is worth 50 per cent more! (Blake’s investment is worth $4,363,970, Barnaby’s is $2,683,184. That’s the power of long-term investing. That’s the power of time.

Long-term investing great way to grow your finances, even if you don’t have a lot to begin with and especially if you start early. Compounding returns thankfully take some of the pain out of saving for the future. It’s easy to increase contributions to your KiwiSaver through your employer or by making a one off or regular deposit (FAQs | Pathfinder Asset Management), or if you think you may need your money sooner than age 65 you can look at investing outside KiwiSaver in an ethically managed fund.
