To Combine or Not Combine
The decision to combine finances or keep them separate sits at the heart of a married couple’s financial wellbeing. In the end, it shapes what the household actually prioritizes. Yet the choice is often clouded by cultural noise and strong emotions. I’m sure the title of this post alone made some readers tune me out.
My professional mission is to help households build lasting financial wellbeing, and a couple’s ability to coordinate on money has a bigger impact than almost any other financial decision. So, I’m willing to risk stirring up a little cultural and emotional “stuff” to address this subject head-on. I realize some of my clients keep finances separate, others combine them, and all of them have their reasons. There’s room for respectful disagreement on this subject. As an advisor, it’s not my job, or desire, to tell clients what to do, but the data is too compelling not to share.
The Cultural Noise
American culture is highly individualistic and constantly pushes us to look out for “number one.” We see it in movies, social media, and music. Unfortunately, some professionals echo the same message. In a 2012 Huffington Post article, psychologist Stephanie Sarkis advised couples to keep separate financial accounts because “one person is usually a saver and one is a spender”, and money arguments “can get heated and even lead to a breakup.”[1] I agree with the observation, people do have different spending styles, but her conclusion (just let each person do their own thing) misses the mark. First, a psychologist isn’t the best source for financial strategy, especially one that could make or break your goals. Second, if the spender just has their own accounts, they’ll almost certainly end up with less than their partner, which is hardly a recipe for harmony. Third, and most important, the vast majority of research shows that couples with separate finances have more money arguments, not less.
The Emotional Stuff
Money and relationships stir up powerful emotions, and I’ve seen at least three subtle beliefs that push people toward separate accounts based on perception.
One common subtle belief is that the money we earn reflects our self-worth. Giving up full control over “my” bank account can feel like giving up part of our dignity. But the value of our accounts and our value as a person are two separate things. If a car accident left someone unable to work, their worth as a person wouldn’t drop one bit.
Another belief that can creep in is that each partner should contribute exactly 50/50. This can leave the lower-earning spouse feeling guilty about spending “their share.” The problem? Life is rarely 50/50, and expecting finances to be the one exception creates significant tension.
The most common reason I hear for keeping finances separate, is a desire to protect oneself should the relationship fail. On the surface, this seems prudent, but the data tells a very different story: separate finances are bad for relationships, and even worse for women.
Separate Finances and Our Relationships
A 2022 University of Colorado Boulder study by Gladstone, Garbinsky, and Mogilner found that couples who fully shared all their accounts experienced greater feelings of “financial togetherness” and significantly higher relationship satisfaction. Their results also showed that couples who kept finances separate faced roughly 22% higher risk of relationship dissolution over a 12–14-year period compared to those who combined everything.[2] Even stronger support comes from a 2023 randomized controlled experiment by Jenny Olson and her colleagues. Researchers followed engaged and newlywed couples (all of whom started with separate finances) and randomly assigned some to merge into joint accounts while others stayed separate. Over the next two years, the couples with joint accounts sustained high relationship quality, reported better financial harmony, and felt more “in this together.” While those who kept their finances separate experienced a decline in marital satisfaction.[3] Having worked with couples for years, these findings don’t surprise me. Practically speaking, tracking who paid for what is exhausting and breeds resentment. Over time, even small things like a Netflix subscription or a “Target run” can become a flashpoint. More importantly, without full transparency it’s hard to know whether both partners are truly pulling in the same direction. A lack of mutual access to all accounts can quietly erode trust, the foundation of any strong partnership. I know I just criticized a psychologist for giving financial advice and here I am, a financial advisor giving relationship advice, but I’m willing to die on this hill. Shared goals and transparency create trust. A lack of transparency and an “every man for himself” attitude diminishes it. The way we manage our family finances has to align with that simple reality.
Separate Finances and Women’s Wellbeing
I know this is controversial, but on average, separate finances are unfair to women. First, women typically earn and accumulate less wealth over time (I discussed the reasons for this in detail here). Second, nearly all states follow equitable-distribution (common-law) rules in divorce rather than a strict 50/50 split. Courts consider factors like length of the marriage, age, and earning potential when dividing assets. As a result, women who keep finances separate typically end up living on less income and building fewer assets than women in pooled arrangements and, if the worst happens, there’s no reason to believe a divorce court will let them keep “their” individual accounts. When you combine these well-documented legal patterns with the research above, the conclusion is clear: women trying to protect themselves through separate finances are often worse off.
How Can We Protect Ourselves and Enjoy Happier Marriages?
For legally married couples, I strongly recommend combining finances. My experience and the data both show that joint accounts create stronger relationships and greater net worth. But combining accounts isn’t magic. Couples still need shared vision, accountability, and open communication. Think of it like a football team. Every player has different skills, but they share one clear objective: get the ball into the end zone more than the other team. When everyone agrees on the goal, understands how they can contribute, and is willing to be accountable, the team plays better, respects each other more, and actually enjoys the game. The same is true for personal finance. Shared vision, shared accounts, and real accountability give couples the best chance at lasting financial wellbeing, even if they never become “financially independent”. The two most fundamental tools for couples seeking financial wellbeing are a common goal and joint bank accounts. Assuming you and your partner can be trusted with full transparency, sit down, talk openly about what you both want, and align all your financial resources behind that common goal.
