Many couples are now finding hybrid ways of managing home finances – but it doesn’t always work
Husband and wife looking over bills
Almost half of couples feel their household finances are not divided fairly but many find it too awkward to start a conversation about money with their partner. New research from MoneySuperMarket found that a quarter of people say their financial agreement benefits their partner.
The shift away from traditional shared joint accounts has opened the door for a variety of ‘hybrid’ financial arrangements – from splitting finances 50/50 to contributions proportional to earnings. Among couples with separate accounts, it is more common for one partner to pay a larger share of the bills than for bills to be split 50/50. One in 10 split their bills proportionally according to their salaries and 7% divide their bills on an ad hoc basis.
However, just a quarter regularly sit down and discuss their financial set-up, and the same proportion have not changed their agreement despite rising expenses, purchasing a house together or starting a family.
Harriet Smith, 35, a parent of three, told how having an honest conversation with her husband about money helped save their marriage after two years of disagreements. Harriet and Scott, 37, from Wiltshire, pooled their money in a single joint account after their wedding in April 2017 – believing it was “just what people did.”
However they decided to separate out their accounts two years later – after opening up about the resentment they were experiencing over their shared finances. Harriet said: “Becoming a hybrid finance couple has had such a huge, positive impact on our relationship – it was like a weight lifted overnight.
“Sharing a joint account was really tough. I would get annoyed about something Scott had spent on a weekly basis. We got to the point where we were arguing all the time – over things like him spending £4 on a sandwich. I don’t think it would have torn us apart, but it’s easy to see how for some couples it does. If we hadn’t had our daughter, it might have been a different story.
“What saved us is that we have always been able to have really honest and open conversations, and we eventually sat down with each other and said: ‘Look, something needs to change.”
Harriet said: “We now each pay a proportion of our total bills dependent on our salary – I pay 60% and Scott pays 40%. We don’t contribute equally, but it’s a fair and balanced way of managing our bills. And if our bills went up to a point where either of us had next to nothing left over at the end of the month, we would adjust the split again to make things fair.”
Kara Gammell, Personal Finance Expert at MoneySuperMarket, said: “With fewer couples relying on traditional joint accounts, we’re seeing a rise in hybrid finances – a flexible approach that allows partners to manage money in a way that suits their individual circumstances.
“It’s important for couples to be open about their finances and work together to find arrangements that feel fair and adaptable as life changes. Splitting bills isn’t a one-and-done decision – from moving in together to job changes and rising living costs, financial arrangements often need a rethink to keep things manageable.”
Kara’s tips for reassessing your financial set-up
1. Schedule a regular money check-in
Don’t wait for a big life event to review your finances. Set a date every few months to talk openly about bills, savings and goals. This keeps things fair and avoids surprises.
2. Be honest about income and spending
Transparency is key. Share what you earn and what you spend so you can agree on contributions that feel fair for both partners. Agree on a spending limit for big purchases so you can check in with each other before committing.
3. Consider proportional contributions
If one partner earns more, splitting bills based on income rather than 50/50 can help balance things and reduce resentment.
4. Use tools to make it easier
Free resources like MoneySuperMarket’s Bill Split Calculator can show how costs are shared, while the Credit Score tool helps you understand the impact of joint financial links on your credit profile.
5. Keep it flexible
Life changes – from moving in together to rising living costs – mean your financial arrangement should adapt too. Review and adjust as needed to keep things manageable.
