Seeking expert commentary: why do smart people make bad money decisions

In property finance, the immediate deadline can dominate the decision. That might mean completing a purchase, repaying an expiring bridging loan or buying more time to sell a finished development. The danger is treating “I can get the finance” as the same as “I can repay it”.

Short-term funding can serve a clear purpose, but the useful question is: what will actually change during the extra time? Will a sale complete, will the borrower qualify for a mortgage, or is the same problem simply being pushed further ahead? Looking at the full cost and what happens if the planned repayment is delayed helps bring tomorrow’s consequences into today’s decision.

Financial decision-making is continuous pricing, risk allocation and capital efficiency under uncertainty. Markets judge every choice on cold arithmetic, return per unit of risk, opportunity cost, liquidity and margin of safety. Every move sits against the macro anchors: rate differentials, inflation decay and the time value of money. Capital parked in one asset forfeits the yield of another, always. Whether you’re managing cross-border FX exposure or structuring a balance sheet, the discipline is the same: balance liquidity against systematic risk. Forwards, swaps and options are simply balance sheet management by another name, match durations, lock in cash flows, cap the tail risk. Markets eventually strip capital from emotional operators and reward systematic execution, marking to market daily with no sunk cost bias. We humans, though, are emotional creatures, bias and ego get in the way of the rational brain. And you don’t know what you don’t know.

Knowing the sensible financial decision and actually making it are two different things. Money decisions often come with stress, fear and short-term pressure, so people naturally focus on what makes them feel better today rather than what leaves them better off in five years.

You see the same thing with mortgages. Someone may know they should review their deal early, reduce expensive debt or avoid stretching their budget, but it is very easy to put off an uncomfortable decision until it becomes urgent. Financial education helps, but good habits matter just as much. Give yourself time, compare the total cost rather than just the monthly payment, and avoid making major financial decisions when you feel under pressure to act immediately.

A lot of our financial behaviour is shaped by our upbringing and the attitudes towards money we were exposed to growing up. Add busy working and family lives into the mix, and it’s very easy to put financial decisions off, particularly if you already know there are things you’ve been avoiding. The reality is that after a long day at work, very few people want to spend their evenings and weekends doing financial admin. Technology and AI can help people understand their options and give them a good indication of what they should be thinking about, but knowing what to do and actually doing it are two different things.

That’s where working with someone can be valuable. It brings accountability and helps answer the important questions: Am I on the right path? What should I tackle first? And which decisions are likely to have the biggest impact? Getting your finances in better shape doesn’t have to happen overnight but small steps can make a significant difference.

Money decisions are rarely just about maths or logic. They're driven by emotion, fear and habits learnt and built over a lifetime.

Some people chase instant gratification, spending today at the expense of tomorrow. Others do the opposite. I've seen wealthy clients live unnecessarily frugal lives, terrified of running out of money, only to die with substantial wealth and leave a sizeable inheritance tax bill.

Financial education alone won't fix this. Stress, shame and anxiety can override even the best financial knowledge.

The answer is to take emotion out of individual decisions by having well defined lifestyle goals, a clear financial plan, modelling future needs and understanding what you can genuinely afford.

The biggest financial regret isn't always spending too much. Sometimes it's spending too little and never enjoying the wealth you've worked so hard to build (and giving too much away on death in taxes!).

Knowing what to do with money and actually doing it are two very different things. Our relationship with money often starts in childhood, shaped by what we saw, heard and experienced growing up. We're all human, and our brains often fall back on familiar habits and beliefs because they feel safe, even when they're no longer helping us as adults.

Money is rarely just about numbers: stress can make us focus on surviving today rather than planning for tomorrow. Shame can stop us opening bills or asking for help, while spending can offer a temporary dopamine hit, comfort or sense of control.

Financial education matters, but understanding our behaviour is just as important. I encourage my clients to recognise their spending triggers and ask, "What need am I trying to meet with this purchase?" Pausing before spending and questioning beliefs we've carried since childhood can make a real difference. Lasting change comes from understanding not just what we do with money, but why.

People don't make financial decisions in spreadsheets. They make them in real life, often when they're stressed, exhausted or looking for something that makes them feel better.

Someone can understand the importance of saving and still spend £300 impulsively after a terrible week. That's not a knowledge problem. It's a behavioural one.

Shame makes things worse. People avoid bank statements, ignore debts and delay seeking help because confronting their finances feels overwhelming.

This is why financial education alone isn't enough. Teaching compound interest won't automatically change someone's relationship with money.

At Roxton Wealth, we incorporate behavioural finance into our advice process because understanding habits matters as much as understanding income.
My advice? Automate savings, introduce a 48-hour rule for emotional purchases and identify spending triggers.
Financial success isn't simply knowing what to do with money. It's understanding why you sometimes do the opposite

Knowing the sensible thing doesn't help much when your bank balance says there's money to spend. Part of it is already owed on bills and card balances. The habit I see in e-commerce is letting high turnover and constant cash hide the real profit, so sellers don't save for tax. Unprofitable sellers rack up credit card bill after credit card bill until the bubble pops, which I see far too often. How emotion, shame and stress work is for a psychologist. Financial education alone isn't enough, because you can't act on numbers you never look at. The simplest guard against emotional spending is seeing where your money actually went, so treat your household like a business, as I do. My personal bank accounts and credit cards are connected to Xero, the accounting software. I run an imaginary tax return on my own life, then split what's left between investments, savings and leisure. You'll definitely cancel a lot of subscriptions once you start reconciling your numbers every month.
