My artist husband likes to say that if I were in charge of our spending, we’d be sitting on milk crates instead of furniture and that if he were in charge, we’d have no retirement accounts.

The fact that we have both nice furniture and retirement funds is a testament to compromise — and the wealth-building power of marriage.

Married people are significantly wealthier than single people in every age group, and the gap tends to widen as people approach retirement age. Married couples age 55 to 64 had a median net worth, excluding home equity, of $108,607 in 2011, the latest available Census Bureau figures show. By contrast, single men in the same age bracket were worth a median $14,226 and single women $11,481.

Income and education also contribute heavily to wealth — and to the likelihood that people will marry. But a 15-year study of 9,000 people found that even after controlling for those and other factors, marriage itself contributed to a 4 percent annual increase in net worth. The same study found that wealth typically began to drop four years before a divorce, which ultimately reduced people’s wealth by 77 percent.

Since marital status is so powerfully associated with financial status, people would be smart to view marriage as a business arrangement in addition to a romantic one. Taking a few pages from the business world has certainly made our 19-year marriage stronger as well as wealthier.

In my latest for the Associated Press, a look at what works for us and how to apply it to your own marriage.
