What does a 1% fee actually cost?

A 1% annual fee sounds small. Over 20–30 years of compounding, the difference between a 1.05% active fund and a 0.30% index fund is often six figures. Set your numbers below — same starting balance, same gross return, only the fee differs.

The fee gap

$26,797

Caveats

  • Real-world returns vary year to year. This calculator assumes a constant gross return and constant fee — useful for illustrating the fee impact, not for forecasting actual outcomes.
  • Past performance is not a reliable indicator of future returns.
  • Tax (PIR) is NOT applied here. Use the PIR calculator to see the tax impact separately.
  • Fund-fee figures are usually quoted "after performance fees" or "before performance fees" — check the PDS to confirm.
  • This is general information only, not personalised financial advice.
