Baby boomers entering their “second acts” should think about these matters.

Retirement is undeniably a major life and financial transition. Even so, baby boomers can run the risk of growing nonchalant about some of the financial challenges that retirement poses, for not all are immediately obvious. In looking forward to their “second acts,” boomers may overlook a few matters that a thorough retirement strategy needs to address.

For millennials, today is the right time.

If you are under 30, you have likely heard that now is the ideal time to save and invest. You know that the power of compound interest is on your side; you recognize the potential advantages of an early start.

Now is the time to explore the possibilities.

Grandparents Day provides a reminder of the bond between grandparents and grandchildren and the importance of family legacies.

Save and invest, year after year, to put the full power of compounding on your side.

Have you been saving for retirement for a decade or more? In the foreseeable future, something terrific is likely to happen with your IRA or your workplace retirement plan account. At some point, its yearly earnings should begin to exceed your yearly contributions.

A lack of money is but one answer.

Common wisdom says that you should start saving for retirement as soon as you can. Why do some people wait decades to begin?

Nearly everyone can save something. Even small cash savings may be the start of something big if they are invested wisely.

Sometimes, the immediate wins out over the distant. To young adults, retirement can seem so far away. Instead of directing X dollars a month toward some far-off financial objective, why not use it for something here and now, like a payment on a student loan or a car? This is indeed practical, and it may be necessary. Even so, paying yourself first should be as much of a priority as paying today’s bills or paying your creditors.

Some workers fail to enroll in retirement plans because they anticipate leaving. They start a job with an assumption that it may only be short term, so they avoid signing up, even though human resources encourages them. Time passes. Six months turn into six years. Still, they are unenrolled. (Speaking of short-term or transitory work, many people in the gig economy never get such encouragement; they have no access to a workplace retirement plan at all.)

Other young adults feel they have too little to start saving or investing. Maybe when they are further along in their careers, the time will be right – but not now. Currently, they cannot contribute big monthly or quarterly amounts to retirement accounts, so what is the point of starting today?

The point can be expressed in two words: compound interest. Even small retirement account contributions have potential to snowball into much larger sums with time. Suppose a 25-year-old puts just $100 in a retirement plan earning 8% a year. Suppose they keep doing that every month for 35 years. How much money is in the account at age 60? $100 x 12 x 35, or $42,000? No, $217,114, thanks to annual compounded growth. As their salary grows, the monthly contributions can increase, thereby positioning the account to grow even larger. Another important thing to remember is that the longer a sum has been left to compound, the greater the annual compounding becomes. The takeaway here: get an early start.1

Any retirement saver should strive to get an employer match. Some companies will match a percentage of a worker’s retirement plan contribution once it exceeds a certain level. This is literally free money. Who would turn down free money?

Just how many Americans are not yet saving for retirement? Earlier this year, an Edward Jones survey put the figure at 51%. If you are reading this, you are likely in the other 49% and have been for some time. Keep up the good work.2

Why striving to stay in the workforce a little longer may make financial sense.

The median retirement age for an American woman is 62. The Federal Reserve says so in its most recent Survey of Household Economics and Decisionmaking (2017). Sixty-two, of course, is the age when seniors first become eligible for Social Security retirement benefits. This factoid seems to convey a message: a fair amount of American women are retiring and claiming Social Security as soon as they can.1

What if more women worked into their mid-sixties? Could that benefit them, financially? While health issues and caregiving demands sometimes force women to retire early, it appears many women are willing to stay on the job longer. Fifty-three percent of the women surveyed in a new Transamerica Center for Retirement Studies poll on retirement said that they planned to work past age 65.2

Staying in the workforce longer may improve a woman’s retirement prospects. If that seems paradoxical, consider the following positives that could result from working past 65.

More years at work leaves fewer years of retirement to fund. Many women are worried about whether they have saved enough for the future. Two or three more years of income from work means two or three years of not having to draw down retirement savings.

Retirement accounts have additional time to grow and compound. Tax-deferred compounding is one of the greatest components of wealth building. The longer a tax-deferred retirement account has existed, the more compounding counts.

Suppose a woman directs $500 a month into such a tax-favored account for decades, with the investments returning 7% a year. For simplicity’s sake, we will say that she starts with an initial contribution of $1,000 at age 25. Thirty-seven years later, she is 62 years old, and that retirement account contains $974,278.3

If she lets it grow and compound for just one more year, she is looking at $1,048,445. Two more years? $1,127,837. If she retires at age 65 after 40 years of contributions and compounded annual growth, the account will contain $1,212,785. By waiting just three years longer, she leaves work with a retirement account that is 24.4% larger than it was when she was 62.3

A longer career also offers a chance to improve Social Security benefit calculations. Social Security figures retirement benefits according to a formula. The prime factor in that formula is a worker’s average indexed monthly earnings, or AIME. AIME is calculated based on that worker’s 35 highest-earning years. But what if a woman stays in the workforce for less than 35 years?4

Some women interrupt their careers to raise children or care for family members or relatives.

Whether you want to leave work at 62, 67, or 70, claiming the retirement benefits you are entitled to by federal law is no casual decision. You will want to consider a few key factors first.

How long do you think you will live? If you have a feeling you will live into your nineties, for example, it may be better to claim later. If you start receiving Social Security benefits at or after Full Retirement Age (which varies from age 66-67 for those born in 1943 or later), your monthly benefit will be larger than if you had claimed at 62. If you file for benefits at FRA or later, chances are you probably a) worked into your mid-sixties, b) are in fairly good health, c) have sizable retirement savings.1

If you sense you might not live into your eighties or you really, really need retirement income, then claiming at or close to 62 might make more sense. If you have an average lifespan, you will, theoretically, receive the average amount of lifetime benefits regardless of when you claim them; the choice comes down to more lifetime payments that are smaller or fewer lifetime payments that are larger. For the record, Social Security’s actuaries project the average 65-year-old man living 84.3 years and the average 65-year-old woman living 86.6 years.2

Will you keep working? You might not want to work too much, for earning too much income can result in your Social Security being withheld or taxed.

Prior to Full Retirement Age, your benefits may be lessened if your income tops certain limits. In 2017, if you are 62-65 and receive Social Security, $1 of your benefits will be withheld for every $2 that you earn above $16,920. If you receive Social Security and turn 66 this year, then $1 of your benefits will be withheld for every $3 that you earn above $44,880.3

Social Security income may also be taxed above the program’s “combined income” threshold. (“Combined income” = adjusted gross income + non-taxable interest + 50% of Social Security benefits.) Single filers who have combined incomes from $25,000-34,000 may have to pay federal income tax on up to 50% of their Social Security benefits, and that also applies to joint filers with combined incomes of $32,000-44,000. Single filers with combined incomes above $34,000 and joint filers whose combined incomes surpass $44,000 may have to pay federal income tax on up to 85% of their Social Security benefits.3

When does your spouse want to file? Timing does matter. For some couples, having the lower-earning spouse collect first may result in greater lifetime benefits for the household.4

Finally, how much in benefits might be coming your way? Visit ssa.gov to find out, and keep in mind that Social Security calculates your monthly benefit using a formula based on your 35 highest-earning years. If you have worked for less than 35 years, Social Security fills in the “blank years” with zeros. If you have, say, just 33 years of work experience, working another couple of years might translate to slightly higher Social Security income.4
