All sorts of fees—including administrative, transaction, and investment management charges—can whittle away your nest egg over time. If a worker invests $5,000 annually in a 401(k) over a 35-year period and pays 1.5 percent of the account balance in fees (using constant 2008 dollars and assuming an after-inflation return of 4.9 percent annually), he will have $345,000 at retirement. If the same worker can cut expenses to 0.5 percent of the account balance, his nest egg will be $423,000 at retirement—$78,000 more. But keeping costs low can be difficult because not all 401(k) fees are fully disclosed. Many financial advisers think a reasonable rate to aim for is an expense ratio of 1 percent or less. Low-cost index funds are typically a good way to invest in stocks at rock-bottom prices.
