Millennial twos are more likely to live together, with 65%, versus 37% of Gen Z couples.
More than half of braces, 54%, said finances were part of their decision to move in together. But that doesn’t mean they are splitting expenses righteous down the middle. Half of couples don’t split the mortgage or rent equally, and 39% do not split pet costs equally, the inspection found.

Experts say the survey results underscore that when it come up to sharing expenses, equal isn’t always equitable, or fair. However, the definition of fairness is likely to vary by couple.
“You’re not thriving to have an answer that’s going to be the same for each couple about what is fair,” said social psychologist Michael Kraus, an associate professor of organizational behavior at Yale University.
‘Critically consider’ splitting bills by income
“I advise young couples to seriously consider splitting the household bills coinciding to income and then revisiting it every year as incomes change,” said certified financial planner Cathy Curtis, lurch and CEO of Curtis Financial Planning in Oakland, California.
For example, if your salary represents one-third of your household proceeds, you might be responsible for a third of the rent. Couples should list all the household expenses, including fixed costs and an normal for the variable costs, then split those costs according to income and deposit their allotted amounts monthly in a collective account, said Curtis.

This method can allow both people to have money left over after key expenses for targets such as retirement, especially the person with the lower income, she added.
“When I bring it up, I see relief in the face of the mortal physically making less money,” said Curtis, who is also a member of the CNBC Financial Advisor Council. “I think it’s unconditionally fair [and] I think it makes for greater equity, less resentment and also creates more communication around flush,” she said.

Fairness is going to be rooted in each party’s perception of what is “fair,” and those feels are often distorted and inconsistent with each other, said Kraus.
Couples that communicate and discuss how to administer the finances together and are transparent about their contributions are going to create the “splitting scheme” that they both take to be fair, he said.
For instance, it might not be fair for one couple to split the mortgage or rent evenly because that command be “90% of my check and 40% of yours,” said Kraus. “That might seem unfair to one couple but totally immaculate to another.”
“It’s not going to be a one-size-fits-all for each couple but it’s really going to be based on this kind of communication,” he added.
Twos risk dissatisfaction over perceived unfairness if they skip discussing their financial situations, cautioned Kraus.
“If you’re extremely serious about somebody and they’re serious about you, being able to work through a discussion about fairness is something that you can unequivocally do.”
