Fortune Spotlights Facet insight on money habits of a new kind of couple: SPLITs (Separate Paychecks, Lives Intertwined)

For decades, the average American couple sat down at the kitchen table to combine finances after arriving home from their honeymoon. Our planners are used to working with couples who each hold their own savings accounts, debts and 401(K)s, while sharing a plan that ties it all together. We saw this pattern so frequently, we knew it deserved a name of its own.

A generation ago, keeping your own account looked like betting against your relationship. Today, it’s seen as a sign of maturity and people are much more open to talking about finances than a generation ago. They don’t want to take [investments] apart to merge with a partner. And they shouldn’t have to.

More women also now have serious earning power, and when both partners have careers and comparable incomes, there’s less reason to funnel everything through one shared account.

[SPLITs] are less likely to feel the need to hide a pricey new jacket or justify a weekend trip with friends. That dynamic keeps them on the same team, eliminating a lot of common money fights.

The financial plan you settled on when you were happily childless and renting a townhome in the city may not be the same one you need when you decide to buy a house and have a baby. SPLITs know their lifestyle works best for them, but they’ve been dropped in the middle of a financial landscape that doesn’t support couples with separated finances.
