Expense ratios: What they are & how they work
You won't find them on your account statement
The cost of investing is usually associated with trading commissions and account service fees—items you see as "debits" from your accounts.
But expense ratios are less obvious because they're not itemized on your account statements or confirmations. Instead, each fund's expenses are deducted from its total value on a regular basis. And those expenses cut directly into your investment returns.
What an expense ratio is
An expense ratio reflects how much a mutual fund or an ETF (exchange-traded fund) pays for portfolio management, administration, marketing, and distribution, among other expenses.
You'll almost always see it expressed as a percentage of the fund's average net assets (instead of a flat dollar amount).
For example, the average expense ratio across the entire fund industry (excluding Vanguard) was 0.47% in 2022, which equates to $47 for every $10,000 invested. Compare that with Vanguard, where the average for all of our mutual funds and ETFs was 0.08%, or just $8—that's 83% lower!*
How expense ratios are calculated at Vanguard
As each fund passes its fiscal year-end, the annual expense ratio is calculated by dividing the fund's operational expenses by its average net assets. If the fund's assets are increasing faster than its costs, you'll enjoy lower expenses as a fund shareholder.
It's not competitive or promotional. It's not an attempt to attract more money. It's just how we've been doing business for more than 40 years.
