Mental Accounting: How We Categorize Money and Its Impact on Spending

Introduction: The Hidden Psychology Behind How We Perceive Money

Have you ever treated a tax refund differently from your paycheck? Or felt less guilty spending money from a bonus than from your savings? If so, you’ve experienced mental accounting—a psychological concept that influences how we categorize and spend money.

According to Nobel Prize-winning economist Richard Thaler, mental accounting is a cognitive bias that causes people to treat money differently based on its source, intended use, and emotional attachment. This can lead to inefficient financial decisions, overspending, and missed savings opportunities.

✔ The different ways people categorize money
✔ How businesses use mental accounting to influence consumer behavior

1. What Is Mental Accounting?

Mental accounting is a behavioral finance concept that describes how people mentally separate their money into different “accounts” rather than viewing all money as interchangeable. These mental accounts impact how we save, spend, and invest.

1.1 Common Mental Accounts People Use

People typically categorize money into:

• Income vs. Windfalls – Treating regular earnings differently from unexpected money (e.g., tax refunds, bonuses, lottery winnings).
• Needs vs. Wants – Prioritizing necessities over discretionary spending.
• Sunk Costs – Continuing to spend on something because of past investments (e.g., keeping a gym membership despite not using it).
• Savings vs. Spending Accounts – Feeling reluctant to spend money from a savings account even when necessary.
• Emergency vs. Luxury Funds – Keeping emergency savings untouched while freely spending on non-essentials.

2. How Mental Accounting Affects Financial Behavior

2.1 The Illusion of Free Money: Treating Windfalls Differently

✔ People often splurge tax refunds, bonuses, or gifts instead of saving them.
✔ Studies show that unexpected money is 35% more likely to be spent frivolously than earned income.
✔ Large sums received unexpectedly often lead to “lifestyle inflation,” where people upgrade their lifestyle rather than saving.

✅ How to Overcome It:
✔ Treat all money the same—allocate windfalls to savings or investments.
✔ Automate savings to prevent impulse spending.
✔ Follow the 50/30/20 rule—50% essentials, 30% discretionary, 20% savings.

2.2 Emotional Attachment to Certain Types of Money

✔ People hesitate to spend savings but freely use credit cards.
✔ We create “untouchable” emergency funds but ignore high-interest debts.
✔ Many struggle to move money from a “vacation fund” to cover an unexpected bill, even when it’s financially wiser.

✅ How to Overcome It:
✔ Balance saving and debt repayment—use Self to manage both seamlessly.
✔ Treat all money as interchangeable; focus on net worth, not mental categories.
✔ Use a zero-based budgeting approach to allocate every dollar purposefully.

2.3 The Sunk Cost Fallacy: Holding onto Bad Financial Decisions

✔ Continuing with unprofitable investments because of past effort or money spent.
✔ Keeping unused subscriptions or services to “get value” from them.
✔ Sticking to expensive habits because you’ve already “invested so much.”

✅ How to Overcome It:
✔ Cancel unused services—Track subscriptions easily with PocketGuard.
✔ Learn to cut losses; money already spent should not dictate future choices.
✔ Conduct a quarterly financial audit to identify wasteful spending.
