Twenty-three percent of married couples in the United States kept zero joint bank accounts in 2023, according to a U.S. Census Bureau analysis of marital finances — up from just 15% in 1996. That’s a jump of more than half in under three decades, and it hasn’t leveled off. Among couples who do share some money, the share keeping absolutely everything joint has also slid, falling from 53% to 40% over the same stretch. The generation getting married right now isn’t slowly drifting toward separate finances. It’s rejecting the old assumption that marriage automatically means one shared checkbook, and the numbers show the break starting on the wedding day itself.
Younger Couples Are Leading the Break
A December 2025 Bankrate survey of more than 1,200 adults in committed relationships found that 62% keep at least some money separate from their partner, and 26% keep their accounts completely separate with nothing shared at all. Break it down by generation and the pattern gets sharper: 51% of Gen Z adults in relationships keep everything separate, compared with 34% of millennials, 23% of Gen X, and only 15% of baby boomers. Combined finances run the opposite direction — 45% of boomers pool everything, versus just 22% of Gen Z.
Ted Rossman, Bankrate’s senior industry analyst, put it plainly in the report: “The ‘yours, mine and ours’ approach works well for couples maintaining privacy while pursuing shared goals.” Income plays a role too. Households earning under $50,000 a year are more than twice as likely to keep everything separate (39%) as households earning $100,000 or more (17%) — though higher earners lean hardest into a hybrid setup, at 47%. That pattern cuts against the assumption that separate accounts are mainly a wealth flex for couples who can afford independence. For a lot of lower-income households, keeping a portion of every paycheck untouched looks less like a lifestyle choice and more like a safety net.
Marrying Later Changes the Math
Part of the shift traces back to when people are actually getting married. The Census Bureau’s data shows the median age at first marriage climbed from 24.8 for women and 27.1 for men in 1996 to 28.4 and 30.2 by 2023. That extra half-decade or more of financial independence matters: among women who married between ages 30 and 34, only 29% ended up with fully joint accounts, compared with 47% of women who married between 20 and 24. Couples who build a decade of solo credit history, retirement accounts, and spending habits before a wedding are, understandably, less inclined to fold it all into one account the day after the ceremony. A 32-year-old marrying for the first time already has a mortgage application, a 401(k), and a credit score built entirely without a spouse in the picture — merging all of it isn’t a simple decision to sign a form together, it’s untangling years of separate financial identity.
Marriage length pulls the numbers the other direction. Couples married nine to thirteen years show 79% joint-account adoption, versus 68% for those married four to eight years — evidence that even reluctant newlyweds tend to merge more over time rather than less, once trust and shared goals accumulate.
What the Research Says About Relationship Satisfaction
None of this means separate accounts are a warning sign. Research from Joe Gladstone (University College London), Emily Garbinsky (Notre Dame), and Cassie Mogilner Holmes (UCLA Anderson), summarized by UCLA Anderson Review, did find that couples with fully joint accounts reported slightly higher median relationship satisfaction (6.10 on a 7-point scale) than couples with mixed accounts (5.82) or fully separate ones (5.46). Using data from a 10-year British cohort study, the same researchers found separation rates climbed alongside financial separation too: 24% for fully pooled couples, 26% for partial pooling, and 30% for fully separate finances.
But the researchers themselves are careful to note the effect doesn’t hold for couples together less than a year, and that plenty of couples have legitimate reasons to keep money apart — personal autonomy, safety, and protection from financial abuse among them. A joint account doesn’t manufacture trust that isn’t already there, and a separate one doesn’t automatically signal its absence.
What the data actually captures is a generation renegotiating what “sharing a life” requires. Fewer newlyweds see a single joint account as the price of admission to marriage, and more of them are building financial partnerships that look like theirs alone — separate statements, shared goals, and a lot less assumption about what comes standard.
