Want a long, happy marriage? Merge your bank accounts! Couples who share finances have ‘substantially’ better relationships, study finds
- Married couples with joint bank accounts have better relationships
- They also fight less over money and feel better about how finances are handled
The Beatles famously sang ‘Money can’t buy me love’.
But couples who manage their finances together may love each other for longer, according to new research.
A study has shown married couples who have joint bank accounts not only have better relationships, but they fight less over money and feel better about how household finances are handled.
Researchers recruited 230 couples who were either engaged or newly married, and followed them over two years as they began their married lives together.
Everyone began the study with separate bank accounts. Some couples were assigned to keep their separate accounts, and others were told to open a joint account instead.

A third group was also allowed to make the decision on their own.
Analysis revealed couples who opened joint bank accounts reported substantially higher relationship quality two years later than those who maintained separate accounts.
The scientists said merging funds means couples are more aligned with their financial goals and are more transparent with each other.
It also leads to a ‘communal understanding of marriage’ – when partners respond to each other’s needs – they said.
Meanwhile couples with separate accounts viewed financial decision-making as more of an exchange, and may think it easier to leave the relationship, they suggest.
Some 20 per cent of participating couples did not finish the study, including a significant percentage of those who separate after not merging bank accounts.
Author Jenny Olson, from the Indiana University Kelley School of Business said: ‘When we surveyed people of varying relationship lengths, those who had merged accounts reported higher levels of communality within their marriage compared to people with separate accounts, or even those who partially merged their finances.

‘They frequently told us they felt more like they were ‘in this together.’
‘This is the best evidence that we have to date for a question that shapes couples’ futures; and the fact that we observe these meaningful shifts over two years, I think it’s a pretty powerful testament to the benefits of merging.
‘On average, merging should warrant a conversation with your partner, given the effects that we’re seeing here.’
The findings were published in the Journal of Consumer Research.
