Let's say you're 20 years old, earning $70,000 a year with a super balance of $20,000. If you make no additional contributions on top of your employer's contributions, your super balance at retirement is estimated to be $543,599.
If you started to contribute $500 a month (a bit over $100 a week), your estimated super balance jumps to $1,002,393. Of this, $282,000 is the amount you've contributed and $123,995 is the extra investment earnings you've made on those contributions.
As you can see from this example using Moneysmart's super calculator, starting to make extra contributions while you're young can have a huge impact on your final super balance.
