Keep your money working harder for you

Kaiden and Jen are both 60 years old and want to maximise their retirement funds by the time they reach 70.


Kaiden decides to invest his super in a cash investment option. His reasoning is that while he won’t earn a huge amount of interest, he’s unlikely to lose any money.


Jen decides to keep all her super invested in a balanced investment option. She understands there’s an element of risk with exposure in the stock market but that there’s also the possibility of higher growth.

Here’s what could happen to both.
