Boston couples are happier than the average couple because they talk about finances, according to TD Bank’s recent “Love and Money” survey.

Only 8 percent of Boston couples argue about money on a weekly basis, which is 7 percent less than the national average, the survey said.

Ryan Bailey, head of consumer deposits, payments and non-real estate lending, said TD Bank was inspired to learn about how couples, especially young ones, manage their money, and how important money is in their relationship.

“We’re always looking for interesting ways to learn more about our customers and what matters to them,” he said. “The results highlight how important it is for couples to talk about money, and we found that people can discuss money regularly and having happy, healthy relationships.”

Among the 60 percent of Bostonians who talk about money at least once a week, 70 percent said they were either extremely happy or very happy in their relationship.

“Bostonians’ happiness is on par with the national results – 70 percent of Bostonians reported they are happy in their relationships, compared with 73 percent nationally. However, we found that they also argue about money less,” 8 percent versus 15 percent, Bailey said.

Couples in Boston are also more likely to make financial decisions together; 85 percent of respondents said they make large financial decisions together, compared with the national average of 78 percent.

Of both Bostonians and Millennials, “seven in 10 respondents believe that talking about money/finances is imperative,” the survey said.

“Millennials talk, and fight, more about money but are also happier (83 percent) than the national average (73 percent). As a whole, the survey found that talking about money regularly is a great thing for happy relationships, regardless of generation,” Bailey said.
