More bank accounts, more problems

Couples may choose to keep their bank accounts separate to avoid marital conflict, but those who pool their finances together are actually happier and, usually, richer.

Less than half (or 43%) of couples pool their finances together without keeping any separate bank accounts, according to one survey. About one-third of couples have some combination of joint and separate accounts, leaving more than one-fifth who choose not to share their finances at all.
