There are a number of variables at play, but one you should know is the sequence of returns. If you start taking income withdrawals from your portfolio in a down market, and continue that course without making adjustments, your money may not last as long as you need it to.
Early Negative Returns vs. Early Positive Returns Hypothetical Example
Jim, age 65, has $500,000 in savings invested in an index fund that mirrors the performance of the S&P 500. He begins to withdraw 5% each year for income. Compare the difference in his portfolio balance in the graph below.
In each scenario, the average annual rate of return is 4.95 percent. But starting withdrawals in years with negative returns yields a very different portfolio outcome than when withdrawals begin in years with positive returns.
