Managing money is about more than balancing budgets or crunching numbers – it’s about achieving financial wellbeing, and making good financial decisions even when things are uncertain and complex. Feeling confident and in control of your finances is essential for reducing stress, building stability, and reaching long-term goals. And this goes beyond just making logical calculations. Human factors play a big role in the process of financial decision-making, both in personal finance and in businesses. While individuals track expenses and plan to save for their future, investors work to optimize their portfolios as they seize opportunities and balance risks. Whatever the context, understanding the psychological factors is key to making better financial decisions and avoiding common pitfalls. 

Understanding the psychology behind financial decisions

The way we approach financial decisions is shaped by psychological tendencies and emotions in ways we often don’t even realize. While sometimes useful, these factors may also steer us away from our financial goals. For example, ‘present bias’ makes spending today feel more rewarding than saving for tomorrow, and ‘emotional spending’ can lead people to make impulsive purchases that provide short-term satisfaction but derail long-term financial goals. 

On top of many psychological factors, life’s inevitable surprises add additional hurdles – like an unexpected medical bill or car repair. Without sufficient saving buffers or emergency reserves, many people find themselves unprepared for such expenses. In fact, 42% of Americans don’t have enough savings to cover an unexpected bill over $1.000, while nearly 1 in 5 people (18%) could only have enough savings for an emergency expense of $100 or less. This financial vulnerability can cause stress and anxiety, and leads people to rely on high-interest debts or other risky financial decisions to cover unforeseen costs. The good news? There are ways to break this cycle.

Behavioral Science helps uncover the patterns behind how people spend, save, and invest. It reveals the subtle ways in which contexts, emotions, and cognitive biases influence financial decisions. For example, some people may delay saving for retirement because that goal feels so distant, while smaller rewards today feel more satisfying. Yet others may avoid creating a budget altogether because they don’t know where to start or they fear facing their financial reality. By understanding how people treat their money, and the root causes of why they’re doing so, Behavioral Science helps uncover barriers that otherwise may be overlooked. These insights allow us to create evidence-based tools and strategies that resonate with how people think and act naturally. 

For example, financial decision-makers can create strategies that align the ‘mental accounting’ that people naturally tend to use when making decisions. People tend to sort their money into ‘mental buckets’ that shape how they save or spend it. Imagine someone who’s been saving up for their dream vacation. When faced with an unexpected expense, like a broken refrigerator, they might feel reluctant to take money out of their ‘dream vacation bucket’, even though it could be the more practical choice. Similarly, many people treat their end-of-the-year bonus way more freely than their regular income, viewing it as ‘extra money’ rather than part of their overall resources. By better understanding these behavioral tendencies, organizations interested in improving financial decision-making can help users form better mental models, and encourage financially healthier behavior. 

Behavioral design in fintech solutions

Digital tools have made managing money more accessible than ever, but flashy features and dashboards alone are rarely enough to drive real impact. Behaviorally informed tools go beyond functionality. Much like building healthy habits, knowing what to do and actually doing it are two very different things. People often struggle with self-discipline, motivation, or even knowing where to start. The key to truly helping people lies in understanding their financial goals, worries, and motivations – and designing solutions that meet them where they are, encouraging sustainable financial behaviors that align with their goals.

So, what does this look like in practice? To illustrate this, here are some examples of topics we focus on:

• Enhancing investment risk perception: Creating app interfaces and communication strategies that clearly explain or even visualize risks and opportunities, empowering people to make more informed investment decisions.

• Strengthening financial resilience: Developing tools and features that help create financial buffers to prepare for a rainy days.

• Optimizing insurance adoption: Using behavioral insights such as mental accounting, illusion of control, or optimism bias to design relatable insurance offerings and encourage adoption.

• Promoting sustainable investing: Making it easier for people to invest in sustainable ways that align with their values and improve their long-term financial goals. 

• Improving investment decision-making: Capacity building for decision-makers in professional settings to improve insights and eliminate common errors.

The challenge isn’t just making one single good financial decision – it’s building systems that sustain those choices over time. Behavioral insights and strategies ensure that financial tools aren’t just another app on someone’s phone but become part of how people live their financial lives.
