All couples argue, but what are couples fighting about the most?
Of over 1,000 American adults polled in a national telephone survey, 27 percent of participants said that disagreements over finances were most likely to erupt into an argument -- not children, chores, work or friends.
The survey also found that couples average three arguments a month about financial issues.
Researchers believe that the conflict may stem from failing to discuss money on a regular basis. Fifty-five percent of those surveyed who were married or living with a partner said that they don't regularly set aside time to talk about financial issues.
For that reason, says HuffPost Weddings blogger and financial expert Jennifer Calandra, couples should have a financial conversation before they exchange their "I Dos."
"One of the biggest roadblocks we see is a lack of communication about finances, which seems to get worse as the years go on," she wrote in January. "Make it a point to establish your level of expectation from the beginning regarding communication. It will help significantly as time goes on."
Below, five other reasons couples fight, according to AICPA data:
Nearly half of couples surveyed argued over unexpected expenses.
More than one-third of couples fought about insufficient savings.
Three in 10 married or cohabiting adults have hidden purchases or made major purchases without telling their partners
Couples aged 45 to 54 argue an average of four times per month about finances.
For more than half of couples whose financial status had declined over the last year, financial disagreements caused major arguments.
