What does one per cent really cost?

A one per cent fee sounds small. Over thirty years, it can eat a third of your final portfolio. Time turns small fees into large losses.

Frequently asked questions

What is a good fee level?

For a self-managed index portfolio: under 0.30 per cent all-in is excellent (platform plus fund TER). 0.30 to 0.50 per cent is reasonable. 0.50 to 0.80 per cent is on the high side. Above one per cent needs justification. If you have an advisor, expect to pay an additional 0.50 to 1.00 per cent for their service. Fair if they earn it via tax planning, behavioural coaching, and complex situations. Expensive if they are just rebalancing the portfolio annually.

Why does a small fee cost so much?

Because fees compound. Every year a fee comes out, the portfolio is smaller, so next year's gain on that money is smaller too. Over thirty years, the compounding gap dwarfs the headline fee number. The longer the horizon, the worse it gets.

Are there other hidden costs?

Yes. Transaction costs, bid-ask spreads, fund-of-fund layering, advisor platform mark-ups, exit penalties. The published ongoing charges figure is often less than the true all-in cost. When choosing, ask for the all-in number including transaction costs and any platform tier-up at higher balances.

Is paying for an advisor ever worth it?

Sometimes. The value is in tax planning, complex household coordination, behaviour during volatile markets, and complex financial events (divorce, inheritance, sale of a business). Pure rebalancing of a passive portfolio is not usually worth advisor-level fees. The honest test: would you make a different decision without their input, and is that decision worth the fee?
