Why do fund fees matter so much?

They compound against you every year

Fund managers | TradeLiga

Pension funds, insurers and many savings apps all hand money to the same kind of firm: an asset manager. Its fund managers decide where billions go.
Active funds pay experts to pick investments and try to beat the market. Passive funds simply copy an index, like the S&P 500 or India's Nifty 50, at a low cost.
The biggest, BlackRock, manages more than US$10 trillion. That's more than twice the yearly economic output of Japan.
Long-term scorecards are harsh. Over 15 to 20 years, around 90% of US large-company active funds did worse than the S&P 500.
Fees are a big reason. US$10,000 growing 7% a year for 30 years becomes about US$76,000. With a 1% yearly fee, you end with about US$57,000: about 25% less.
Common mistake
Myth: "Last year's top fund will win again." Top performers rarely stay on top. Research finds low fees are one of the most reliable signs of better future results.
Key takeaway
Fund managers invest other people's money. Most active funds trail their index after fees, so always check what a fund costs.

A passive fund... Copies an indexA passive fund holds what the index holds, so it needs no star picker and can charge low fees.
Over long periods, most active funds... Trail their index after feesLong-term scorecards show around 90% of US large-company active funds trail the S&P 500 over 15 to 20 years.
Why do fund fees matter so much? They compound against you every yearA fee takes a slice every year, and that slice can no longer grow, so the gap widens over time.
Two funds track the same index. Fund A charges 0.1% a year, fund B 1%. Which likely leaves you more? Fund ASame index, same holdings, so the cheaper fund keeps more of the return for you.
