The fee on every fund over a working life

A fund's yearly fee is taken out of returns every year for as long as the money is held, so over a working life a difference of one percentage point removes a large share of the final balance.

Who this exists for. This exists for anyone contributing to funds for decades, since a yearly fee compounds against the saver the same way returns compound for them. Ticks that show it: My job offers a retirement plan (401(k), 403(b), 457, TSP); I have an IRA or an old workplace plan; I hold investments outside retirement accounts; I am under 50.

How it works

A fee of 1 percent a year on a fund earning 7 percent leaves the holder 6 percent, and the dollars taken by the fee also stop compounding. Over 40 years of steady contributions the 1 percent fee removes close to a quarter of what the balance would have been at 0.1 percent, because each year's fee is charged on a larger balance and each lost dollar misses every later year of growth. The fee is listed in the fund's documents as an expense ratio and in a workplace plan's yearly fee disclosure, which the plan is required by federal law to provide. Index funds tracking the same market as a higher cost fund are available in most plans and at every major broker. The fee is one of the few figures about a fund known in advance.

What it gives

A lower fee is a certain gain of the same size every year, unlike a return.

The figure is published for every fund and can be compared in minutes.

Switching funds inside a retirement account has no tax cost.

What it costs, or where the catch is

A plan menu may offer no low cost choice in some asset classes.

Switching funds in a taxable account can trigger capital gains tax.

Fee differences feel tiny year to year, so the cost is easy to ignore.

A worked example

Lucia saves $600 a month for 40 years. At 7 percent minus a 0.1 percent fee, she ends with about $1,531,000. At 7 percent minus a 1 percent fee, she ends with about $1,195,000. The gap of about $336,000, which is $1,531,000 minus $1,195,000, is the fee plus the growth the fee prevented, on total contributions of $288,000, which is $600 times 480 months.

Where it goes wrong

The common miss is leaving a plan's default fund in place for a career without once reading the fee disclosure the plan mails each year.
