Most couples feel confident about managing money together, yet nearly half deliberately avoid talking about it, according to Fidelity Investments' 2026 Couples & Money study. The study, based on a national survey of 3,193 married or partnered American adults, found that 49 percent of couples avoid money conversations to prevent arguments, and almost one in four admit to hiding a financial secret from their partner, according to Fidelity.
The gaps start early. Sixty-eight percent of couples said they did not know their partner's complete financial situation before moving in together, and for nearly one in five it took more than a year after moving in before the full picture came into focus, according to Fidelity. Only 42 percent combine their finances into joint accounts, while about one in five keep everything separate. Fifty-eight percent say they do not contribute equally to household finances, and nearly one in four say the imbalance affects the relationship.
A separate report from the CFP Board, published on 5 October 2026, reaches a similar conclusion from a different angle. Nearly two-thirds, 65 percent, of married or partnered Americans say money is a top relationship stressor, including 34 percent who call it their number one source of stress — ahead of health at 46 percent, work-life balance at 36 percent and household chores at 35 percent, according to the CFP Board. Forty-six percent say money is the most uncomfortable subject to discuss with their partner.
Both studies point to the same fix: talk more, and talk earlier. Half of the couples in Fidelity's study wish they talked more about day-to-day finances, a wish shared by 64 percent of Gen Z and 63 percent of millennials, according to Fidelity. Fifty-three percent said being on the same page about money habits is a key factor in a successful relationship, and 52 percent said planning shared experiences — date nights, hobbies and holidays — is the best way for money to strengthen their bond. The CFP Board found that 72 percent of couples consult their partner before a big purchase, yet 41 percent made a major financial decision in the past year without telling their partner.
Readers should note that these are two different studies with different samples and dates — Fidelity surveyed 3,193 partnered adults between 14 October and 2 November 2025, with a margin of error of plus or minus 2 points, while the CFP Board surveyed 820 married or partnered Americans between 2 and 4 September 2026, with a margin of plus or minus 3.4 points — so their figures are not directly comparable, and this article keeps them attributed separately. The shared lesson is simple: a short, regular money check-in, before moving in and after, costs far less than the argument it prevents.
