Frequently Asked Questions

How does Vanguard make money on ETFs?

Vanguard earns revenue from expense ratios on its ETFs and mutual funds. Despite having some of the lowest fees in the industry, Vanguard manages over $8 trillion in assets. Even at 0.03%, a fund like VOO generates significant revenue due to its massive scale.

Do ETF investors pay for securities lending?

Securities lending income typically benefits the fund and its shareholders, not just the issuer. When an ETF lends its shares to short sellers, the lending income can offset expenses and slightly improve fund returns. Vanguard returns 100% of lending income to the fund.

Why are ETF fees so low?

Competition and scale drive fees down. Most index ETFs require minimal management, and issuers compete aggressively for assets since even small fee differences drive investor flows. The race to zero has made broad index ETFs nearly free to own.
