You’ve got relationship compatibility. But what about financial compatibility?

Girl meets boy, sparks fly, the relationship blossoms and they spend a lifetime together. That’s the textbook version of love. Reality, however, can look very different once money enters the picture.

Almost every milestone a couple shares is intertwined with money. Yet somewhere between planning the wedding, applying for a BTO flat and budgeting for renovations, many overlook a more fundamental question: Are we financially compatible?

According to a 2024 Moneysmart study, one in four Singaporeans reported having had a relationship break down because of money, while 58 per cent have argued with their partner about finances.

So, what is financial compatibility? Contrary to popular belief, financial compatibility isn’t about earning the same income, agreeing on every purchase or sharing identical spending habits, says Lee Xin Hui, senior wealth manager at Prestige Wealth.

Money is rarely just about money. For some, it represents security. For others, freedom, opportunity or independence. Those beliefs are often influenced by childhood experiences, family values and personal circumstances.

For Kaushik* and Sheila*, growing up in households where money was carefully managed became the foundation of their financial life together.

“We are both the type of people who spend what we don’t save, although how we see value in something may differ,” they say, explaining that purchases are usually made as replacements rather than additions. Sheila pays close attention to household spending and price tags, while Kaushik takes a broader view, focusing on value over price.

For Leshwyn Raj and Astari Pinasthika Sarosa, the contrasting perspectives emerged early. Astari saw money as freedom and the ability to enjoy meaningful experiences. Leshwyn, whose family experienced financial hardship, viewed it as security and future opportunity – a mindset that eventually led him to become a financial adviser.

“Today, I still believe money isn’t about buying more things. It’s about creating freedom, reducing stress, and giving the people you love options when life becomes unpredictable,” he says.

Astari recalls how one of their earliest conversations somehow turned into a discussion about investing. “I remember thinking, ‘Why would anyone willingly lock away money for 10 or 15 years?’ It honestly felt uncomfortable because I had always valued having immediate access to my savings.”

Different financial styles don’t necessarily mean incompatibility, says Xin Hui. “Risk appetite is the most common difference I see. The real source of tension, however, is mismatched financial discipline, where one spends most of every pay cheque, while the other saves compulsively,” she adds. “That directly threatens whether shared goals get funded, and it shows up month after month, not just at annual reviews.”

How to navigate finances as a couple

As relationships become more serious, Xin Hui encourages partners to look beyond who pays for what. She also advises partners to openly discuss their income, debt obligations and insurance coverage. Before buying a home, they should understand how much debt they are comfortable taking on, and the implications of different ownership structures. Starting a family brings another set of conversations, from childcare costs to how career breaks may affect household finances.

Xin Hui often recommends an “own pot, shared pot” approach, where each partner retains financial autonomy, while contributing to a common pool for shared goals.

For Kaushik and Sheila, financial compatibility is rooted in trust, shared values and recognising each other’s strengths. “Over the years, I have certainly learnt to pay attention to the details, and Sheila has learnt to trust that I do. Other than that, our fundamental philosophy hasn’t changed,” says Kaushik.

Looking back, however, they wish they had spoken earlier about their long-term life goals and how money could help achieve them, rather than simply focusing on saving.

Leshwyn and Astari arrived at financial compatibility differently.

“I used to think compatibility meant agreeing on everything,” says Leshwyn. “Now I think it means understanding each other’s values, and respecting why those values exist. You don’t need identical habits, but you do need shared goals.”

And the perfect formula is the one that you create together.
