Couples Now Keeping Finances Separate

It used to be that uniting your lives as a married couple also meant a union of bank accounts, but new research suggests that’s hardly a given anymore. Fidelity Investments’ new 2026 Couples & Money Study shows that these days, only 42% of couples combine their finances into joint accounts.

According to the research, about one in five now keep all of their finances separate, and that number has more than doubled since 2018. Younger Americans are leading the shift, as 34% of Gen Z and 26% of millennials prefer fully separate accounts, compared to 19% of Gen X and 15% of baby boomers.

• Independence is important to many, as two-thirds say they value having financial autonomy.
• Younger couples are also preparing for the unexpected, with more than a quarter of Gen Z couples saying they have a formal or informal prenup in place. That’s twice as many as the general population.
• While most couples report feeling good about how they communicate with their partner, 68% admit they didn’t know their partner’s complete financial situation before moving in together.
• For nearly 20%, it took more than a year of living together before they learned it all.
• Less than a third regularly talk about day-to-day finances or long-term financial decisions and almost half (49%) avoid money conversations to prevent arguments.
• But nearly a quarter (24%) admit they’re still hiding a financial secret from their partner.
• Most couples see themselves as being good financial partners, but half wish they talked more about money, and that jumps to 64% for Gen Z and 63% for millennials.
• More than half (52%) say planning for fun spending, like date nights, vacations and hobbies, is the best way to let money make their relationship stronger.
• When it comes to household finances, 58% of couples don’t contribute equally and nearly a quarter say that imbalance has a negative impact on their relationship.
• Currently, 46% of women feel financially dependent, compared to just 16% of men.
• Even if they’re not talking about it, 56% are monitoring their partner’s spending and 31% say they’re “keeping score” on how much their partner spends.
