Dear Liz: My wife is distressed by your recent column about how many multiples of salary are needed to retire. She interpreted the column as saying you must have the sum total of those numbers. So if you need one times your salary saved at 30, three times by 40, six times at 50 and eight times at 60, she thinks you would need 18 times your salary in total by age 60, or $1.8 million if you earn $100,000. I interpreted it to mean that your target would be $800,000 at age 60. Am I wrong?

Answer: You are interpreting the guidelines correctly: You would need eight times your salary at 60, not 18 times. The numbers, by the way, come from Fidelity Investments and are meant as general guidelines for people hoping to retire at 67 (at which point, Fidelity says they should have 10 times their salaries saved). Your needs may vary; some people will need less, some will need more. People who have large traditional defined benefit pensions, for example, may not need to save as much, while those who want to retire early or indulge in expensive hobbies, such as traveling or supporting adult children, may need to save more.

Guidelines tend to be the most helpful when you’re many years away from retirement and only guessing about how much money you’ll need. Once you’re five to 10 years from your desired retirement age, you should have a better handle on your likely expenses and sources of income. Well before you actually retire, though, you should consider consulting with a fee-only, fiduciary financial planner for a second opinion on your retirement plans. (“Fee only” means the advisor is compensated only by fees paid by clients, rather than through commissions or other arrangements. “Fiduciary” means the advisor is required to put your interests first.)

The National Assn. of Personal Financial Advisors, the XY Planning Network and the Garrett Planning Network all represent fee-only planners and can offer referrals.
