Understanding Why We Spend
Feb 20, 2025
Our spending habits are shaped by a complex web of psychological, social, and emotional factors. Whether we’re buying a cup of coffee, investing in the stock market, or splurging on a luxury item, there’s always a deeper reason behind our purchasing decisions. Understanding the psychology of spending is crucial for anyone looking to build long-term wealth, because impulsive, emotional, or poorly planned spending can often undermine even the best financial strategies.
A report from Behavioural Insights Team (BIT), an organisation that explores the science of human behaviour, highlights how emotions, social pressures, and cognitive biases all influence our purchasing decisions. This article will explore the psychology behind why we spend the way we do and how understanding these behavioural drivers can help improve your financial health.
1. Spending as a Status Symbol: The Influence of Social Pressures
One of the most powerful psychological drivers of spending is the need for social validation. People often make purchases to project a certain image or status. In his book The Wealth of Humans, Ryan Avent explains that conspicuous consumption—buying items to showcase wealth or success—has been a driving force in economic systems for centuries.
A study by the University of Chicago found that people are more likely to buy luxury goods when they feel their social status is under threat. In a world where social media amplifies the visibility of wealth and status, the desire to "keep up" with others can lead to excessive spending on items that don't necessarily improve long-term happiness.
For example, spending money on a high-end car or designer clothes might give an immediate boost in social validation, but these purchases often have little to no lasting impact on one’s financial wellbeing. In fact, a Harvard Business Review study showed that individuals who prioritised status spending were more likely to experience financial stress and have lower long-term savings.
2. The Role of Emotional Spending
Emotions play a significant role in shaping our spending habits. Whether it’s retail therapy after a bad day or splurging to celebrate an achievement, spending often serves as a coping mechanism. Emotional spending refers to the act of making purchases based on feelings rather than logic or necessity.
Research by Cambridge University suggests that emotional spending is often a short-term fix to deeper emotional needs such as stress, loneliness, or self-esteem issues. Unfortunately, emotional spending can lead to guilt or regret later on, especially when it results in financial strain.
The American Psychological Association (APA) found that emotional spending is more prevalent during times of economic uncertainty. For instance, during the COVID-19 pandemic, emotional spending surged, as people turned to online shopping as a way to cope with stress and isolation. A survey by NerdWallet revealed that 37% of people admitted to making purchases they later regretted, with most citing emotional reasons as the cause.
3. Instant Gratification and the Power of Delayed Rewards
In the digital age, we are accustomed to getting what we want almost immediately. This has fuelled a culture of instant gratification, where the desire for immediate rewards outweighs the benefits of long-term financial planning. The famous Stanford Marshmallow Experiment demonstrated the power of delayed gratification, showing that children who could wait longer for a second treat tended to have better life outcomes, including financial success, later in life.
The concept of delayed gratification is crucial for wealth building. According to a report from the National Bureau of Economic Research, individuals who prioritise saving and investing rather than spending on immediate pleasures are more likely to achieve financial independence. For example, instead of spending a £1,000 bonus on a new gadget, investing it in the stock market could lead to significantly higher returns over time due to compounding.
However, resisting the temptation of instant gratification is easier said than done. A study by The Royal Society for Public Health (RSPH) found that the ease of online shopping has exacerbated impulsive spending habits. With one-click purchases and same-day delivery, consumers are more likely to make hasty decisions without considering the long-term consequences.
4. The Sunk Cost Fallacy: When We Can’t Let Go
Another psychological principle that impacts our spending is the sunk cost fallacy. This occurs when individuals continue investing time, money, or effort into something because they have already made significant investments, even if it no longer makes financial sense. For example, holding onto a poor-performing investment or continuing to pay for a subscription service that no longer adds value are both examples of the sunk cost fallacy at work.
A study by The Journal of Economic Psychology found that 70% of people are likely to make irrational financial decisions due to the sunk cost fallacy. This bias often leads to overspending because people feel compelled to “get their money’s worth,” even when it’s financially prudent to walk away.
To combat the sunk cost fallacy, financial experts recommend focusing on future costs and benefits rather than past investments. Behavioural finance expert Dan Ariely advises that acknowledging a loss and moving on can free up resources to be used more effectively elsewhere, rather than continuing to pour money into a failing venture.
5. The Power of Habit in Spending
Our daily spending habits have a profound effect on our long-term financial health. Small, repeated purchases—such as a daily takeaway coffee or frequent dining out—might seem insignificant on their own, but they can add up over time and take a substantial toll on your budget. This phenomenon is sometimes referred to as "the latte factor," a term popularised by financial author David Bach to illustrate how small, habitual expenses can prevent people from saving and investing effectively.
A Fidelity Investments survey showed that 43% of people were unaware of how much they spent on non-essential purchases each month. Once participants tracked their spending, many were surprised to discover that cutting out small expenses could free up hundreds or even thousands of pounds annually for savings and investments.
Building positive spending habits, such as automating savings or setting up a budget, can help mitigate the impact of unnecessary expenses. A study by Harvard Business School found that people who automate their savings and set up financial goals are more likely to achieve long-term success compared to those who rely solely on willpower.
6. The Impact of Cognitive Biases on Spending
Cognitive biases, such as anchoring and confirmation bias, can also influence how we spend money. Anchoring occurs when individuals rely too heavily on the first piece of information they receive, such as the price of an item, and use it as a reference point for future decisions. For example, if someone sees an item listed at £500 and then discounted to £300, they might perceive it as a good deal, even if the actual value of the item is much lower.
Confirmation bias is the tendency to seek out information that supports our existing beliefs, which can lead to overspending on items that we feel justify our lifestyle choices. A study by The Behavioural Economics Team of the Australian Government (BETA) found that cognitive biases can lead to overspending, especially in environments like sales events or when making large purchases such as cars or homes.
Conclusion: Building Better Spending Habits for Financial Success
Understanding the psychological factors that influence our spending decisions is the first step toward building healthier financial habits. From the sunk cost fallacy to the impact of social pressures, these psychological drivers can lead us to make choices that harm our long-term financial health. By becoming aware of these influences, you can make more informed decisions that align with your financial goals.
The key to financial success is balancing emotional, social, and psychological influences with rational decision-making. By setting up systems, such as automated savings and budget tracking, and by recognising the biases and emotions that drive spending, you can gain more control over your financial future.
