The Psychology of Spending: Why We Buy Things We Don’t Need

Ever found yourself walking out of a store (or closing an online checkout) with items you never planned to buy? You’re not alone. Many of us succumb to spending triggers that lead to impulse purchases and unnecessary expenses. But why do we do it? Understanding the psychology behind spending can help us take control of our financial habits and make more intentional choices.

Why Do We Overspend?

1. Emotional Spending

Emotions play a major role in our spending habits. Stress, boredom, sadness, and even happiness can push us to shop as a way of coping or celebrating. Buying something new provides a temporary mood boost by releasing dopamine, the brain’s “feel-good” chemical. However, this effect is short-lived, and soon, we may feel regret or financial strain.

2. The Power of Marketing

Companies are experts at influencing our purchasing decisions. From strategic product placements to persuasive advertising, businesses use psychological tactics to make us feel like we need their products. Flash sales, limited-time offers, and phrases like “Only 2 left in stock!” create a sense of urgency, compelling us to buy before we even think it through.

3. Social Influence & FOMO (Fear of Missing Out)

Social media fuels the fear of missing out. When we see friends, influencers, or celebrities showing off their latest purchases, we feel an urge to keep up. This leads to spending money on things we may not actually want or need, just to feel included or up-to-date with trends.

4. The Ease of Digital Payments

Spending money has never been easier. With one-click purchases, digital wallets, and buy-now-pay-later services, we can make transactions without feeling the financial impact immediately. Unlike handing over cash, digital payments make money seem less tangible, leading to more impulse buys.

5. Justifications & the Illusion of a Good Deal

Sales and discounts create the illusion that we’re saving money, but in reality, we’re often spending more than we originally intended. We justify purchases by telling ourselves we got a “good deal” or that an item is an “investment,” even when it’s not a necessity.


How to Control Impulse Spending

While spending money is unavoidable, being mindful of how and why we spend can help us make better financial decisions. Here are some strategies to regain control:

Recognise Your Triggers

Pay attention to what prompts you to spend unnecessarily. Is it stress? A sale notification? Social media trends? Identifying your triggers helps you pause and reconsider your choices.

Use the 24-Hour Rule

Before making a non-essential purchase, wait 24 hours. This gives you time to assess whether you truly need or want the item, reducing impulse buying.

Set a Budget and Track Your Spending

Creating a budget for discretionary spending ensures you don’t go overboard. Use apps or spreadsheets to monitor your expenses and identify patterns in your spending habits.

Unsubscribe & Reduce Temptation

Unsubscribe from promotional emails, unfollow brands or influencers that encourage impulse spending, and remove shopping apps from your phone if necessary.

Pay with Cash Instead of Cards

When possible, use cash for non-essential purchases. Physically handing over money makes spending feel more real and helps prevent overspending.

Ask Yourself Key Questions Before Buying

Before making a purchase, ask yourself:

  • Do I really need this?
  • Will I use it regularly?
  • Can I afford it without regret?
  • Am I buying this because of a sale or social pressure?

If the answers suggest it’s an impulse buy, reconsider the purchase.


Understanding the psychology behind spending empowers us to make smarter financial decisions. While it’s okay to treat yourself occasionally, being mindful of your habits ensures that your spending aligns with your financial goals.

Next time you feel the urge to splurge, pause, reflect, and make an intentional choice. Your future self (and your bank account) will thank you.
