Rewards vs. Interest: Do Credit Card Rewards Actually Pay Off?
The math only works if you pay in full
Rewards are real money, but small: a good card returns 1 to 2 percent of what you spend. Interest is the opposite, large: the average APR on a balance that carries is about 21.5 percent. Those two numbers decide everything. If you pay your statement in full, you keep the rewards and pay no interest, so the rewards are pure gain. If you carry a balance, the interest dwarfs the rewards almost immediately. A 7,900-dollar balance at 21.5 percent costs roughly 1,700 dollars a year in interest, while the rewards on a typical year of spending might be 300 to 500 dollars. You are paying three dollars to earn one. See how interest works.
The numbers, nationally
Zoom out and the gap is stark. Here is what the data shows.
| Metric | Figure |
|---|---|
| Average APR on balances that carry interest | About 21.5 percent (2026) |
| Cardholders who carried a balance in the past year | About 45 percent |
| Average balance carried | About $7,900 |
| US credit card interest charged in 2024 | About $160 billion |
| Total US credit card balances | About $1.25 trillion |
| Typical rewards rate on spending | 1 to 2 percent |
Total US credit card interest reached about 160 billion dollars in 2024, up from roughly 105 billion in 2022, against an estimated 30-or-so billion in rewards value handed out. As a country, cardholders pay far more in interest than they get back in points. The rewards only beat the interest for the people who never trigger the interest in the first place.
Who actually pays for the rewards
Rewards have to come from somewhere, and they come from two places: the swipe fees baked into the prices everyone pays, and the interest paid by people who carry balances. Research from the Federal Reserve and others finds this creates a quiet transfer, with cash and debit users and revolvers effectively subsidizing the rewards of those who pay in full, and value flowing on average from lower-income to higher-income households. About 62 percent of below-prime cardholders carry a balance, versus only 17 percent of the highest-credit cardholders, so the people earning the richest rewards are usually the ones avoiding the interest entirely.

How to be on the winning side
The takeaway is simple and a little ruthless. If you pay in full every month, the rewards system is a genuinely good deal, so earn freely and never carry a balance. If you do carry a balance, stop optimizing rewards and attack the debt, because paying off a 21.5 percent balance is a guaranteed 21.5 percent return that no rewards card can touch. Kill the interest first with the avalanche method or a 0 percent balance transfer, then earn rewards once you are paying in full.
