How can I figure out how much money I need to save for retirement? How big does my nest egg need to be?
A good way to think about this is in terms of expenses. At its simplest, a nest egg helps cover your living expenses in later life. With that in mind, the following calculation—courtesy of William Bernstein, an investment adviser and author—can help pinpoint your particular “number” for retirement.
The first step, not surprisingly, is to add up your basic annual expenses. I know, that exercise alone will stop some people in their tracks. But get over it. If you care enough about your future (and you should) to calculate the savings you’ll need for retirement, you can spend part of a weekend examining receipts and account statements and estimating how much you spend each year.
And don’t forget, Mr. Bernstein notes, to include the taxes you’ll owe on withdrawals (voluntary and required) from your retirement accounts and on the income (interest, dividends, capital gains) in your taxable assets.
Once you have that figure, subtract your Social Security and, if you’re fortunate, any money you get from a pension. This will leave you with what Mr. Bernstein calls your “residual living expenses,” or RLE.
Example: You determine that you need $70,000 a year to meet your expenses and pay taxes. And let’s say you receive $30,000 a year from Social Security and a small pension. If we subtract the latter total from the former, we end up with $40,000 in residual living expenses—those that aren’t covered by guaranteed sources of income. Knowing that figure can help you calculate how large your nest egg should be.
Mr. Bernstein recommends that most people should plan to save for about 25 years of RLE. (Which is a reasonable number if you retire at or near age 65, since most financial planners would urge you to assume a life expectancy of 90, if not longer.) To continue our example above, we multiply $40,000 (again, your annual shortfall) by 25 years. That gives us a target of $1 million for your nest egg. That’s how much you would need to save before retiring. The math, of course, isn’t a guarantee of retirement success, Mr. Bernstein notes, but “at least gives you a decent shot at it.”
Obviously, you can play with the numbers somewhat. If you retire at 60—or at 70—you might need more, or fewer, years of RLE. Or if you have a large pension, or modest living expenses, your annual shortfall could be modest, as well. In which case, you might be fine with a relatively small nest egg. But again, the point is to think about retirement savings in terms of assets and expenses: How much will you need to acquire to pay the bills that your guaranteed income won’t cover?
Finally, if you reach your particular savings goal, Mr. Bernstein recommends that the bulk of your portfolio should be invested in relatively safe holdings, such as bonds, Treasury inflation-protected securities and inflation-adjusted immediate annuities. Think about it this way, he suggests: If you have saved and invested well, it’s possible you have “won” the game; you have built the nest egg you need. And if that’s the case, stop playing. In other words, start reducing the risk in your savings.
I just qualified for Medicare and had my “welcome” appointment. I was very surprised that while Medicare covers treatments of all kind, the diagnostic tests (e.g., blood tests for diabetes, cholesterol, etc.) aren’t covered and cost hundreds of dollars. This seems extremely counterproductive. What’s behind this policy?
Something seems to be amiss with your appointment or how you were billed.
In reality, Medicare covers a number of diagnostic tests. Philip Moeller, author of “Get What’s Yours for Medicare,” notes that, in 2010, the Affordable Care Act “greatly expanded the menu of preventive screenings and wellness care available to Medicare beneficiaries, often for free or reduced rates.”
The Medicare website has a section that can help you determine which tests are covered. As you will see, the list includes screenings for diabetes and cardiovascular disease, which includes blood tests for cholesterol levels.
As for your recent appointment, I wonder if an error occurred in how your tests were coded or billed. Certainly worth asking about.
