I already know his blog post is going to ruffle some feathers, but I'll ask you to stick it out and keep reading through the discomfort - it's worth it!
Bottom Line Up Front: You are likely getting racked over the coals by your credit card company and you don't even know it. What's worse is you might think you are coming out on top, again you likely aren't.
Credit card rewards programs are frequently thought of as a source of risk-free financial optimization. The prospect of capturing cash back or travel points on everyday expenditures leads many people to favor credit cards over cash or debit. However, maximizing these benefits requires managing a complex interplay between merchant economics and the underlying psychological forces that govern spending behavior. Understanding these dynamics is essential for maintaining strict cash-flow discipline and not getting taken advantage of.
This month's blog was inspired by a conversation with one of my brothers. So, if you are reading this Dave - thank you!
The Microeconomics of Card Transactions
To evaluate the true utility of credit card rewards, the underlying transaction mechanics must be examined. Credit card networks levy fees—frequently averaging around 3.5%—directly on merchants for processing transactions. To preserve profit margins, merchants typically adjust retail prices upward across all consumer goods to absorb these operational costs.
As a consequence of this uniform price inflation, individuals who utilize cash or debit instruments indirectly subsidize the rewards programs enjoyed by credit card users. Many people think the story stops there and perceive this as a wealth transfer between those who use credit cards and those that don't. It appears this creates an environment where credit card usage is the only method for recovering a portion of these inflated costs, typically via a 1.5% to 2.5% rebate in the form of points or cash back, but there is more to it than meets the eye.
The Psychological Trap: Accelerating Consumer Spending & Disassociating The Pain
While utilizing a credit card to recapture transaction costs appears logical in theory, behavioral research reveals a significant psychological counterweight. Neurological studies, including research conducted by the Massachusetts Institute of Technology (MIT) Sloan School of Management, indicate that the physical mechanism of transacting with credit cards alters consumer spending behavior. Rather than merely reducing the psychological resistance or "pain" of payment, exposure to credit card transaction mechanisms actively sensitizes dopaminergic reward networks in the brain.
Here is how it works when utilizing a credit card: You get the dopamine hit from getting what you want, but the pain of paying happens much later. To your brain, it feels like getting something for nothing. Worse yet, when the credit card bill comes in and you have to pay, you can't really say exactly what you are paying for. In-fact, you are paying down a liability that was accumulated over a wide variety of purchases. This inability to associate the pain of a credit card payment with a specific purchase prevents us from developing a healthy relationship between the reward of getting what we want and the cost of paying for it.
This neurological response functions as an accelerator for purchasing desire, independent of item cost. Historical transaction data demonstrates the following trends:
Consumers utilizing credit cards are prone to spending between 12% and 83% more per transaction compared to those utilizing cash.
- Credit card usage correlates with a higher incidence of impulse purchases and larger overall transaction basket sizes.

Consequently, while you may successfully secure a 1.5% to 2.5% rebate on total transactions, an unmonitored increase in overall consumption easily erases the financial advantage of the rewards. The net beneficiaries in this scenario are the credit card issuers and merchants, who experience expanded transaction volumes at your expense.
Implications for Your Financial Life
Navigating these psychological spending triggers requires careful consideration. The military and veteran community often manage cash flow within the parameters of structured, fixed compensation systems, such as military basic pay, VA disability compensation, or military retirement distributions. The absence of large bonuses, commissions or incentive stock options means there are few opportunities to earn your way out of a credit trap.
The very nature of the reliable paycheck that many of us have earned mean that we are prime targets for credit card companies and lending institutions. We often enjoy additional perks and fee waivers as a result. Unfortunately, this increased access can inadvertently amplify the neurological spending cues highlighted in behavioral research, making structural expense tracking and budgeting even more critical during and after our military careers.
When I was in the Army I got my first and only personal credit card. I had heard about the need for building my credit score and the idea that I could not manage my money effectively seemed absurd to me at the time. Within three months of having a credit card I had already begun to carry a balance. I found it difficult to pay off every month because the timing of the expenses, when I paid on the card and the timing of the interest charges all seemed to happen independently of one another. After another few months, I had my first experience shopping for Christmas while armed with a credit card. I spent more money than I had, and I knew it. That feeling of not being in control of my money left me feeling like I needed a cold shower. I cancelled the card shortly thereafter.
Potential Courses of Action for Cash-Flow Management
Because generalized financial strategies are not universally optimal for every individual, maintaining baseline budget discipline requires assessing personal spending patterns and real financial needs. The following potential courses of action may assist in mitigating the psychographic risks of credit card usage:
Implement a Fixed-Interval Settlement Protocol: Settling outstanding credit card balances at accelerated intervals—such as every Friday rather than waiting for the monthly statement billing cycle—can bridge the time gap between consumption and payment. This practice replicates the immediate feedback loop of a debit card while retaining card security benefits.
Conduct a Categorical Transaction Audit Against Your Budget: Review historical credit card statements alongside a rigid baseline budget to determine if localized overspending is occurring under the influence of rewards incentives. Need help with budgeting? We have a blog about that here.
Employ Hybrid Payment Frameworks: Utilize cash or debit card systems for highly variable or impulse-prone spending categories (such as dining out or discretionary retail), while reserving credit card usage strictly for fixed, recurring household utilities. For example, have your electric bill tied to your credit card but use your debit card at the grocery store and for general shopping.
- Avoid Credit Cards Entirely: Despite what the credit card companies want you to believe, you are not required to have a credit card to build your credit. Many people have a credit history that is primarily tied to student loans, auto loans and mortgages. Notably, these loans finance purchases that are usually well thought out and less likely to be impulsive. It is possible to navigate life without a credit card, as I have done since my early twenties.
Conclusion
Many people believe that since they are able to pay their credit cards off in full every month that they are getting a free ride by earning points and rebates with their credit cards. Unfortunately, there is no such thing as a free lunch. Research shows that individuals utilizing credit cards spend an average of 12% to 83% more per transaction, are more likely to succumb to impulse purchases and buy more items per shopping trip, than those utilizing cash or debit cards.
This doesn't mean that credit cards do not have their place in your financial life, but it does mean that you would do well to think carefully about when and how you choose to utilize them.
