Compare shares
Why this matters. A mix of share indexes grows by the return you type, minus the fees you type. The boxes are assumptions. The past-performance lines are labelled as past, and they are not copied into those boxes. A fall you switch on is an illustration, not a forecast.
Put 100% of starting capital and monthly additions across the three. Drag the mix — it always adds to 100%. The thick line is your blend. The thin lines are 100% in one index, for comparison.

Falls
S&P Dow Jones Indices, education paper on the S&P 500 Managed Risk 2.0 indices. Data from 28 March 1990 to 31 March 2020. The paper does not call these the all-time worst falls, and it is not a 2026 factsheet. The S&P/ASX 200 price-return factsheet as of 30 September 2026 publishes risk as annualised standard deviation. It does not publish a peak-to-trough worst fall, so this page does not print one for the ASX 200.
- S&P 500, Global financial crisis. -55.3% Peak 5 October 2007, trough 9 March 2009. S&P 500 column of that table.

- S&P 500, COVID-19 sell-off. -33.8% Peak 19 February 2020, trough 23 March 2020. The paper’s figures stop at 31 March 2020.

Past performance, not a forecast
The 8.5%, 10% and 12% boxes are assumptions you can edit. They are not these published returns.
- S&P/ASX 200 (TR) ↗ 9.04% a year13 October 2026
10-year annualised. Total return. Not the 8.5% box. S&P Dow Jones Indices, featured total-return table.
- S&P 500 (TR) ↗ 15.72% a year13 October 2026
10-year annualised. The index provider’s total return. Not an unhedged Australian-dollar return, and not the 10% box. S&P Dow Jones Indices, featured total-return table.
Nasdaq-100 past performance is published by Nasdaq. This page does not copy a figure from that page into the 12% box. Nasdaq-100 ↗
Next: If you'd invested — What those markets actually did, not the assumption.
What doctors often miss
The chart uses the returns and fees you type. The extra MER and tax-drag boxes start at 0%. A typed return is not a forecast.
