The Psychology of Money: Why You Keep Overspending

I used to think I had a spending problem. Turns out, I had a psychology problem.

Every month, I'd promise myself I'd stick to my budget. Every month, I'd fail. It wasn't lack of willpower or discipline — it was because I didn't understand the invisible forces controlling my spending decisions.

Once I learned the psychology behind money, everything changed. Here are the mental triggers that were sabotaging my finances (and probably yours too).

The "I Deserve This" Trap

After a long, exhausting week at work, I'd find myself browsing online stores at midnight, cart full of stuff I didn't need. My internal dialogue went something like: "I work hard. I deserve a treat."

This is called reward substitution, and it's one of the most expensive habits we develop. We use shopping as a reward system because it gives us instant gratification. Bad day? Buy something. Good day? Celebrate by buying something. Tuesday? Might as well buy something.

The problem isn't treating yourself — it's using spending as your default reward mechanism.

What worked for me: I created a list of free or cheap rewards. When I felt that "I deserve this" urge, I'd choose from the list instead: taking a long bath, watching a movie I'd been meaning to see, calling a friend, or going for a walk in my favorite park. Sounds simple, but it broke the automatic link between "reward" and "spend money."

The Comparison Trap (AKA Instagram Made Me Poor)

Let's be honest: social media is a financial nightmare. Everyone's posting about their vacation, new car, designer bags, or fancy dinner. Your brain sees this and whispers: "Why don't you have that? You should have that."

This is social comparison spending, and it's brutal because the goalpost never stops moving. There's always someone with more, doing more, having more.

I was spending money I didn't have to impress people I didn't even like, trying to keep up with a lifestyle that was probably 50% credit card debt anyway.

What worked for me: I did a social media audit. I unfollowed accounts that made me feel "less than" or triggered spending urges. I followed personal finance creators instead. I also started a "comparison journal" — whenever I felt jealous of someone's purchase, I'd write it down and check back a week later. 90% of the time, I didn't even remember what I was jealous about. That perspective was eye-opening.

The Future Self Delusion

Here's a thought experiment: imagine your future self one month from now. What will they be grateful for? What will they be frustrated about?

I used to treat Future James like he was some responsible superhero who would magically fix all my problems. Present James would overspend, and Future James would somehow figure it out. Spoiler: Future James was just as broke and stressed as Present James, if not more.

This is called temporal discounting — we value immediate pleasure over future benefits because future consequences feel abstract and distant.

What worked for me: I started talking to myself in second person during spending decisions. Instead of "Do I want this?" I'd ask, "Will you be glad you bought this in a week?" That tiny shift in language made my future self feel more real, more present. Suddenly, I could feel Future James's disappointment or gratitude, and it changed my decisions.

The Sunk Cost Fallacy (Why You Can't Stop Bad Subscriptions)

I kept a gym membership for seven months without going once. Why? Because I'd already paid for it, and canceling felt like admitting defeat.

This is the sunk cost fallacy — continuing to put money into something because you've already spent on it, even when it no longer serves you.

We do this with subscriptions, expensive items we never use, and even relationships. We throw good money after bad, hoping to justify what we've already spent.

What worked for me: I did a "subscription audit" and asked myself: "If this wasn't already set up, would I sign up for it today?" If the answer was no, I canceled immediately. I saved $147 per month just by canceling services I wasn't using but felt bad about letting go.

The Scarcity Trap

"Limited time offer!" "Only 2 left in stock!" "Sale ends tonight!"

These phrases trigger something primal in our brains. Scarcity creates urgency, and urgency shuts down rational thinking. We buy things we don't need because we're afraid of missing out.

Retailers know this. That's why every sale is "ending soon" (until the next one starts).

What worked for me: I implemented the 48-hour rule for non-essential purchases over $50. If I still wanted it after 48 hours, I'd buy it. Turns out, 80% of the time, the urgency faded and I forgot about it entirely. The stuff I did buy after waiting? I actually used and appreciated.

The Bottom Line

Your spending habits aren't about willpower — they're about understanding psychology and designing systems that work with your brain, not against it.

The good news? Once you recognize these patterns, you can't unsee them. You'll start catching yourself before you fall into these traps.

The next time you're about to make a purchase, pause and ask yourself:

• Am I buying this as a reward substitute?
• Am I trying to keep up with someone else?
• Am I thinking about my future self?
• Am I being manipulated by scarcity tactics?

That moment of awareness is often enough to change the decision.

Money psychology isn't about perfection. It's about progress, one decision at a time.
