Dear Liz: I just found out I am cured of cancer. I thought I would be dead in three years and thus did not save very much. I’m 62, single, with no children and an annual salary of $85,000. I’m now contributing the maximum to my employer’s 403(b) retirement plan plus $6,500 to a Roth IRA. My mortgage balance is $380,000 on a 30-year loan fixed at 3.65%. I have about $380,000 in equity. I have about $30,000 saved outside of my $10,000 emergency fund. What should I do with it to get the highest return with minimal risk?

Answer: There’s no such thing as an investment that offers high returns with minimal risk. You get one or the other.

There’s also no such thing as “making up” for decades of not saving, short of an extremely unlikely windfall such as a lottery win or a big inheritance. This is why financial planners tell young people to start saving for retirement from their first paychecks and not to stop or touch those funds prematurely. Waiting until the last minute simply won’t work, and the longer you delay the tougher it will be to catch up — until catching up becomes impossible.

Still, at some point you won’t be able to keep working, so you need to save what you can. The more you save, the better off you’ll be.

Continue to take full advantage of your retirement savings options. Thanks to catch-up provisions, you can put up to $24,000 in your workplace retirement fund (the 2016 limit of $18,000 plus a $6,000 “catch up” for those 50 and over) and $6,500 into an IRA or Roth IRA (the 2016 limit of $5,500 plus a $1,000 catch-up). You’ve saving more than a third of your income, and several years of contributions like that will go a long way toward easing your final years. A balanced approach to your investments, with 50% to 60% in stocks, should give you the growth you’ll need to overcome inflation over the decades to come.

Your home could be another source of funds. Downsizing or moving to a lower-cost area could free up some of your equity to bolster your nest egg. Another option could be a reverse mortgage, but make sure you get objective, expert advice before you proceed.

Finally, it’s crucial to delay claiming Social Security as long as possible, since this benefit is likely to comprise most of your income in retirement and you want that check to be as large as possible. Try to put off claiming until age 70 when your benefit maxes out.
