Rewards programs are designed to make the issuer money — not you
Credit card rewards programs feel like free money. You spend on things you'd buy anyway, and points or cash back accumulate on the side. The problem is that the entire architecture of rewards programs is built around one core assumption: that you will, at least occasionally, carry a balance. When you do, the interest charges — typically 20% to 29% APR on most rewards cards — wipe out months or years of accumulated rewards in a single billing cycle. Card issuers call people who pay in full every month "deadbeats" internally, because they're the only customers who genuinely come out ahead on rewards.
Beyond interest, the rewards system is funded in large part by swipe fees — the interchange fees merchants pay every time you use your card. Those fees are baked into the prices of everything you buy, meaning even people paying cash subsidize rewards cardholders to some degree. But here's what's less obvious: research from the Federal Reserve Bank of Boston found that rewards cards redistribute wealth from lower-income, lower-credit-score households to higher-income, higher-credit-score ones — the people most likely to pay in full and redeem efficiently. If you're not in that latter group, the odds are quietly stacked against you.
There's also a behavioral dimension the card companies understand extremely well. Studies consistently show that people spend more — sometimes significantly more — when paying by rewards card versus cash. The act of earning points psychologically softens the pain of spending, a phenomenon researchers call "payment decoupling." That extra spending is the real engine of the rewards business model. The points are the bait; the incremental spending and occasional interest charges are the catch.
The rewards question looks different depending on where you stand
The "worth it or trap" question has different answers for different people — it depends almost entirely on your spending habits, your ability to pay in full, and how much effort you're willing to put into redemption.
The gap between what you earn and what you lose can be substantial
For cardholders who carry a balance, the math is almost never close. A typical rewards card earning 2% cash back on $1,500 a month of spending generates about $360 a year in rewards. Carry even $2,000 in balance at 24% APR and you're paying roughly $480 in interest — a net loss of $120 before you've accounted for any annual fee. The rewards haven't disappeared; they've just been more than erased. For people who pay in full, rewards are genuinely free money, provided they don't overspend to earn them and actually redeem them before they expire or devalue.
The Consumer Financial Protection Bureau (CFPB) reported in 2023 that Americans paid over $130 billion in credit card interest in a single year — while earning an estimated $35 billion in rewards. At a population level, rewards cards are a net negative for cardholders as a whole. The winners are those who treat their cards like a debit card: spend only what they can cover, pay in full every month, and redeem strategically. Everyone else is, on average, subsidizing that group.

I was convinced my travel card was a great deal — I'd been earning miles for two years. Then I actually did the math and realized I'd paid about $340 in annual fees and interest over that time, and redeemed maybe $180 worth of flights. I cancelled it and switched to a no-fee 2% cash back card and I genuinely feel better about it, even if it's less exciting.

Honestly, rewards cards work great for me — but I'm pretty obsessive about it. I use a spreadsheet, I pay in full every single month without exception, and I only redeem through the airline portal when the cent-per-point value is above 1.5 cents. Last year I got about $900 in flights essentially for free. But I'm also very aware that I'm probably in the minority and that most people I know who have the same card are not getting anywhere near that value.

The thing nobody told me is how hard it can be to actually redeem points for good value. I had 80,000 points on a hotel card and when I went to use them, the "free" nights I wanted required 70,000 points each and blackout dates blocked most of the times I travel. I ended up cashing them out at 0.5 cents per point, which was terrible. I'd earned them at an effective rate of about 1 cent per point. Never again — I want cash back now, simple and predictable.
