The reason is shared consumption of important expenses such as housing, utilities, cars, and so on. The study found that older couples save between 24 and 40 percent more on shared expenditures than their single counterparts.
The study also found that husbands only needed to spend 76 cents to attain the same standard of living that would cost a single man one dollar. And wives only need to spend 60 cents to attain the same standard of living that would cost a single woman one dollar.
The study measured the relative effect of sharing consumption between husbands and wives and found that men spend a higher proportion of household income on their own needs compared to women. Translation: Older men spend more on their man-cave, golf clubs, and the boat than women spend on their shoes, the spa, and beauty supplies.
But this inequality decreases when men have poor health. Translation: When a man's health declines, he reduces his spending on the man-cave, golf clubs and the boat, and more of his consumption is shared with his wife. Individual consumption by women was unchanged by their health.
The results of this study can help married couples plan for the eventuality that one of them will become widowed at some point in their lives; most likely it will be the wife. How much income does she need to maintain her standard of living? It makes sense to plan that the surviving spouse will need at least two-thirds -- and possibly more -- of the couple's household income when both are alive. This has implications for how much couples draw from their 401k savings, when they begin to draw Social Security benefits, and whether they buy a joint and survivor annuity.
Don't want to get married, or that prospect seems unlikely? While the study only looked at married people, it's reasonable to assume that two or more unmarried people who live together and share resources would also benefit from shared consumption -- the "Golden Girls" solution. And that's just the financial impact; a living companion can have significant emotional benefits as well, which will increase the likelihood that you'll stay healthy longer than your "living-alone" counterparts.
Aging boomers, both married and unmarried, will need to make every dollar count in their retirement years. That means making informed and creative decisions about your consumption needs and living arrangements, and planning for the well-being of those who might survive you. Then you can truly look forward to your retirement years!
