How it works
Investment fees are the one factor you control completely, and they compound against you exactly the way returns compound for you. This tool runs the same portfolio through two fee structures — fund expense ratios plus any advisory or platform charge — and shows the ending-value gap over your horizon. The number that shocks people is the total-fees line: a 0.6% combined fee on a growing portfolio does not cost 0.6% of your money once, it costs a slice of every year's growth forever, and over 20 years that routinely exceeds $50,000 on a six-figure portfolio. Fees are measured against a hypothetical zero-fee portfolio, which is why the figure is larger than the sum of the annual charges — you lose the fee and every return that fee would have earned. The comparison is not an argument that fees are always wasted. A 1% advisory fee is worth paying if the advice changes your behaviour by more than 1% a year — staying invested through a crash, rebalancing, tax-loss harvesting, not panic-selling. That is a real service for some investors. But it should be a conscious purchase of that service, not a default. If you will buy and hold index funds regardless, the lower-fee option wins by an amount that compounds into a meaningful fraction of your retirement.
Formula
Net return = gross return - expense ratio - advisory fee | Ending value = FV(portfolio + contributions, net return, years)
Tips
- Compare total fees — expense ratio plus advisory plus platform — not any single line in isolation.
- Index fund expense ratios under 0.1% are the benchmark; anything above 1% needs to justify itself in changed behaviour.
- Fees compound like returns, so judge the gap over your real horizon, not one year's statement.
- An advisory fee is a purchase of discipline and tax planning — pay it deliberately, not by default.
- Re-check the comparison as your portfolio grows; a flat percentage fee grows with it while the service often does not.
Frequently asked questions
- How much do brokerage fees cost over time?
- Far more than the percentage suggests, because fees compound. A 0.6% annual fee on a $50,000 portfolio growing at 8% with $12,000 added yearly costs roughly $60,000 over 20 years — the fee plus every return that money would have earned.
- Is a 1% financial advisor fee worth it?
- Only if the advisor changes your behaviour or tax outcome by more than 1% a year. For a disciplined buy-and-hold index investor it is hard to justify; for someone who would otherwise panic-sell in a crash or miss tax-loss harvesting, it can pay for itself several times over.
- What is the difference between an expense ratio and an advisory fee?
- The expense ratio is charged inside the fund, by the fund manager, on every investor. An advisory fee is charged by your advisor or platform on top, for their service. You pay both, so the comparison has to add them — a low-expense fund inside a high-fee platform is not cheap.
- Are robo-advisors cheaper than human advisors?
- On fees, clearly — typically 0.25% to 0.5% against around 1% for a human. The trade is that a robo rebalances and tax-loss harvests algorithmically but will not talk you out of a bad decision in a panic, which is where human advisors sometimes earn their fee.
- What expense ratio is too high?
- Broad index funds are available under 0.1%, so anything above about 0.5% needs an active reason to exist. Above 1%, the fund must beat the index by that margin every year just to tie — a bar most active funds fail over long periods.
