Wat is een kostenratio?

De jaarlijkse beheerkosten van het fonds als percentage van je investering, automatisch verrekend met het rendement.

The expense ratio is the fund's annual operating cost expressed as a percentage of assets. A 0.03% expense ratio means a $10,000 position costs about $3 per year; a 0.95% ratio costs about $95. You never receive a bill — the fee is shaved off the fund's net asset value day by day, so it quietly reduces your return.

Expense ratios vary enormously by strategy: broad index ETFs can charge 0.02–0.10%, sector and factor funds often 0.10–0.60%, and active, leveraged, or niche funds 0.50–1.00%+. Compare funds within the same strategy — a cheap S&P 500 fund and a 'cheap' single-country fund are different products.

Costs compound just like returns. Over 20 years, the difference between 0.05% and 0.75% on the same gross performance is thousands of dollars per $100,000 invested. Fees are one of the few things an investor controls completely, which is why every fund page here shows them prominently.
