Use conservative, mid, and optimistic return assumptions to see a realistic range of outcomes — then decide what’s feasible for your budget.
Open the Money Growth CalculatorFor Australian high income earners, $1,000 a week is a serious wealth-building commitment — roughly $52,000 a year directed into investments outside of superannuation. At a 7% average annual return broadly in line with long-run ASX and global index performance, your $520,000 in contributions grows to around $750,000 over 10 years, with compounding alone adding around $230,000. This level of investing is common among professionals using low-cost ETFs like VAS, VGS or a mix of both, often alongside maximising concessional super contributions. A portfolio tracker like Sharesight is particularly useful at this scale — it handles tax reporting, dividend tracking and performance benchmarking automatically.
At $1,000 a week, extending your timeline has an enormous impact. Here's how the numbers change across time horizons at a 7% return:
| Time period | Total contributed | Final balance (7%) | Growth from compounding |
|---|---|---|---|
| 10 years | $520,000 | ~$750,000 | ~$230,000 |
| 20 years (scaled: $100/wk) | $104,000 | ~$274,000 | ~$170,000 |
| 30 years (scaled: $100/wk) | $156,000 | ~$529,000 | ~$373,000 |
At $1,000 a week, 10 years puts you close to a million dollars. Extending to 20 or 30 years at this rate would produce extraordinary results — use the calculator to model your specific scenario.
| Return rate | Final balance | Total contributed |
|---|---|---|
| 5% (conservative) | ~$673,000 | $520,000 |
| 7% (mid) | ~$750,000 | $520,000 |
| 10% (optimistic) | ~$888,000 | $520,000 |
Investing $1,000 a week for 10 years means contributing $520,000 of your own money — and at a 7% return, compounding adds around $230,000 on top, growing your balance to roughly $750,000. At this level you're approaching life-changing wealth within a single decade, with compounding alone adding nearly a quarter of a million dollars. For high income earners serious about financial independence, $1,000 a week invested consistently over 10 years puts a seven-figure net worth firmly within reach.
If you invest $1000/week for 10 years, the result depends heavily on the return rate. Use the calculator to test a conservative, mid, and optimistic scenario.
It’s a solid starting habit. The best amount is one you can maintain consistently, then increase over time.
Use 5% for a conservative baseline, 7% for a mid-range estimate, and 10% as an optimistic scenario.
No. Treat results as estimates. You can lower your assumed return rate to be more conservative.
For long-term modelling, converting to monthly is usually close enough.
