Money and Matrimony: Why married couples with joint bank accounts are happier 

Marriages between co-financiers may last longer.

Research shows couples who combine their bank, credit card, and investment accounts are happier over the long run.

Sharing resources also makes it easier for them to reach milestones like buying a home and retirement savings.

Married couples with joint bank accounts not only have better relationships but also dispute less over money.

They also have greater confidence in the management of household finances.

Combining encourages stronger financial goal alignment, transparency, and a shared view of marriage.

Couples with separate accounts see financial decision-making as more of an exchange.
