Run 3 return-rate scenarios to see a realistic range of outcomes — then adjust your monthly amount until it fits your budget.
Open the Money Growth Calculator| Return rate | Final balance | Total contributed |
|---|---|---|
| 5% (conservative) | ~$78,000 | $60,000 |
| 7% (mid) | ~$87,000 | $60,000 |
| 10% (optimistic) | ~$102,000 | $60,000 |
Investing $500 a month for 10 years means contributing $60,000 of your own money — and at a 7% return, compounding adds around $27,000 on top, growing your balance to roughly $87,000. A decade at this level builds a serious financial asset, crossing the $100,000 mark at optimistic returns. For many Australian households $500 a month represents a meaningful but achievable commitment that within 10 years creates a substantial investment foundation.
If $500/month feels hard right now, test a smaller starting amount and increase it each year. Even small step-ups can move the result a lot over long horizons.
It can be. The biggest drivers are consistency and time. Use the calculator to compare multiple return scenarios.
Try 5% (conservative), 7% (mid), and 10% (optimistic) to see a range.
No. Treat results as estimates. You can lower your assumed return rate to be conservative.
If you can’t do both, extra time often helps a lot. Then increase contributions over time.
