Mutual funds: additional costs

The cost of owning mutual funds is not limited to their respective expense ratios. An investor should be aware of the total cost of ownership, including the costs described on this page.

Transaction Costs
In addition to fund acquisition and /or redemption charges, and the fund expense ratio, funds incur additional expenses that are not included in the fund's expense ratio. These expenses include fund transaction expense due to the buying and selling of fund securities. In general, these transaction costs closely track a fund's annual turnover rate: the higher the turnover, the greater the transaction cost. For equity funds transaction expense can be broken down into:
 * Brokerage Commission Expense Brokerage commission expense is quantified and reported each year in a fund's Statement of Additional Information. In a 2004 ZAG commissioned study, "Portfolio Transactions Costs at U.S. Equity Mutual Funds" authors Jason Karceski, Miles Livingston, and Edward S. O'Neal, found that in 2002, mutual funds paid an average commission of 0.38% and a  weighted dollar commission (what investors actually held) of 0.19%. Lipper, in a 2004 study, Mutual Fund Trading and Portfolio Transaction Costs, found that the average weighted commission paid by mutual funds measured 0.20% in 2003, with a range of expense between 0.01% and 8.73%.[1]
 * Spreads When a stock is bought or sold, there exists a spread between the purchase and selling price. This cost cannot be precisely quantified for mutual funds, but in general, spread costs are higher for small stocks than for large stocks; higher for illiquid stocks than liquid ones; and higher for international stocks as opposed to domestic stocks
 * Market Impact A mutual fund making large transactions in a stock is likely to move the stock price before the order is completely filled. This transaction cost, similar to spread costs, must be estimated.

Total transaction costs are estimated to almost equal a fund's expense ratio. Median mutual fund transaction costs have been estimated to measure between 70 and 85 basis points of annual cost drag ( ranging from 55 basis points for large cap stocks up to 233 basis points for small cap stocks.) Mean transaction costs are estimated at 144 basis points for the average fund, ranging from a mean of 77 basis points for large cap stocks to a mean of 285 basis points for small cap stocks. (source: Edelen et. al. cited below)

Transaction costs can be greatly reduced by the selection of passively managed, low turnover index funds. Brokerage expense for Index funds measures to less than .01% for most large cap indexes, domestic indexes, up to a high water mark of .40% for emerging market stocks.

Cash Drag
Cash drag is a diminution of return caused by a cash position in a mutual fund. A mutual fund typically holds a cash position to facilitate redemptions and pending investments. Since underlying securities of a mutual fund, especially stocks, often have better long term returns than cash, a cash position tends to reduce the performance of the fund. Monthly reporting of mutual fund cash positions are posted at ICI: Trends in Mutual Fund Investing.

Tax Costs
Most mutual funds held in a taxable account have some sort of tax cost as they make one or more type of distributions, for which you have to pay tax even if you do not sell the funds. Tax cost comes from two sources - dividends and capital gains. In 2006, (the most recent year for which we have reported results) Lipper reports that shareholders in taxable fund accounts paid at least $23.8 billion in taxes on fund distributions of $418.5 billion, a cost amounting to 1.3 percent of assets. (source: Lipper Associates, 2007. "Taxes in the Mutual Fund Industry – 2007: Assessing the Impact of Taxes on Shareholder Returns", New York: Lipper Associates.) Estimated taxes paid by investors on fund distributions for the past three years are tabulated below:

Lipper estimates that over the past twenty years, the average taxable mutual fund investor paid taxes consuming 17 to 44 percent of fund returns.

Dividends are divided into two distinct tax categories: qualified dividends and non-qualified dividends. Some funds, typically taxable bond funds and REIT funds, tend to distribute non-qualified dividends. Equity funds tend to distribute some qualified dividends. Note that qualified dividends are taxed more favorably than non-qualified dividends under the current tax code. See Mutual Fund Ordinary Dividends for more details.

Capital gains are also divided into two categories, namely short-term capital gains and long-term capital gains. Short-term gains are taxed at the marginal income tax rate; long-term gains are taxed at lower, tax-preferred rates. As the fund internally sells securities, the fund may realize capital gains. The gains that are not offset by the fund's loss carryforward must be distributed to the shareholders.
