The Real Cost of Carrying a Credit Card Balance for One Year
A $5,000 balance can cost between $615 and $1,040 in interest over twelve months, and lost grace periods, late fees, and credit score damage add to the bill.
Carrying a $5,000 credit card balance for one year at the current average rate of about 22% costs roughly $600 to $1,050 in interest, depending on how quickly it is repaid.
The price rises further through lost grace periods, late fees, and a higher credit utilization ratio that can pull a score down.

Most cardholders think about this cost in monthly terms, which is why it stays invisible. A statement shows a minimum payment and an interest charge, never a twelve-month total. Credit card balances reached $1.26 trillion at the end of the second quarter, according to the New York Fed, and nearly half of active cardholders carry a balance from month to month.
The aggregate number is large, but the more useful figure is personal: what one balance costs across a full year, and which decisions change that number.
The Interest Math, Step by Step
Accounts that carry a balance currently pay an average of 22.36% at US commercial banks, based on Federal Reserve data. Consider a $5,000 balance at 22%, with no new purchases. The figures below assume monthly compounding; issuers accrue interest daily, which adds a few dollars. Daily accrual also means a 22% APR behaves like an effective annual rate near 24.6%.
In the first scenario, the cardholder fixes a payment of about $468 a month and clears the balance in twelve months. Total interest lands near $615. This is the floor for a one-year payoff.
In the second, the cardholder pays a flat $200 a month. Interest over the year comes to about $960, and roughly $3,560 is still owed at the end. Payments totaling $2,400 reduced the debt by only about $1,440.
In the third, the cardholder pays only the minimum, calculated here as interest plus 1% of the balance, a common formula. Payments start near $142 and shrink each month. Interest reaches roughly $1,040 across the year, and the balance falls only to about $4,430.
The lowest monthly payment produces the highest annual cost, and the debt barely moves. A useful rule of thumb follows from the arithmetic: every $1,000 left on a 22% card costs about $18 a month, or $220 a year, before compounding pushes it higher.
Why the Rate Stays High Even When the Fed Cuts
Many borrowers expect card rates to fall when the Federal Reserve cuts. They do, but modestly. The federal funds target range sits at 3.50% to 3.75%, which puts the prime rate at 6.75%. Against a prime rate of 6.75%, a 22% card carries a margin above 15 points.
Six quarter-point-or-larger cuts since late 2024 removed 1.75 points from the policy rate. The average rate on interest-bearing accounts has slipped only about one point over the same period, from a record of 23.37% in August 2024. Card pricing reflects credit losses, funding costs, and rewards programs, not only the benchmark rate. A cardholder waiting for relief from policy decisions is waiting on a variable that moves only a fraction of the way.
Costs That Never Appear on the Interest Line
Interest is the visible expense. Four others sit beneath it.
The first is the lost grace period. A card paid in full each month charges nothing on new purchases. Once a balance carries over, most issuers charge interest on new purchases from the day they post, so a $100 purchase begins costing money immediately. This is why a balance that looks stable still feels like it grows.
The second is the late fee. A federal court vacated the CFPB rule that would have cut typical late fees from $30 to $8, because the rule failed the “reasonable and proportional” standard in the CARD Act. Penalty fees therefore remain under the older safe harbor framework. A single missed payment can also trigger a penalty APR, often near 30%, which turns a manageable balance into a compounding problem.
The third is credit score drag. Amounts owed make up roughly 30% of a FICO score, and utilization is the largest piece of that category. A $5,000 balance on a $10,000 limit reports as 50% utilization, well above the 30% level that lenders and scoring models treat as a caution line. The lower score can then raise the price of an auto loan or mortgage.
The fourth is opportunity cost. The national average savings rate is 0.38%, according to the FDIC. Money earning under half a percent while a card charges 22% is a guaranteed loss of more than 21 points. Paying down the card is, in effect, a risk-free 22% return. The sensible exception is an emergency fund: draining it to zero to chase the card can force a worse borrowing decision later.
Common Mistakes That Make the Year More Expensive
The most persistent misconception is that carrying a balance helps build credit. It does not. Payment history and utilization drive scores, and paying in full every month builds the same history without paying a cent in interest.
The second mistake is treating a balance transfer as free. A 0% introductory offer typically carries a transfer fee of 3% to 5%. At 22%, a 3% fee on $5,000 costs $150, which equals less than two months of avoided interest, so the math favors the transfer.
A 5% fee still pays for itself in under three months. The trap lies in the promotional window: balances left after the intro period reprice at a standard rate, often above 20%, and new purchases on the same card can quietly erode the benefit.
The third is consolidating into a personal loan and then running the cards back up. The average 24-month personal loan rate was 11.40% in the Fed’s most recent survey, roughly half the card rate, so the swap is mathematically sound. It fails behaviorally when the freed credit lines get used again.
The fourth is paying the smallest balance first when rates differ widely. The snowball method has real psychological value, and for many borrowers it is the strategy that actually gets finished.
The cost is higher interest than the avalanche method, which targets the highest APR first. Choosing between them is a question of which plan the borrower will sustain for twelve months.
A Practical Payoff Framework
A defensible plan fits on four lines.
First, list every balance with its APR and compute the monthly interest on each. This takes ten minutes and usually surprises the borrower. Second, set one fixed payment above the combined minimums and hold it constant even as minimums fall; this single habit converts a revolving balance into an amortizing one.
Third, rank the options for lowering the rate: a 0% transfer with a payoff date, a fixed-rate consolidation loan, a direct call to the issuer asking for a hardship or reduced rate, or a nonprofit credit counseling debt management plan, which often negotiates lower rates with creditors. Fourth, pause new spending on the card being repaid, so the balance can only move in one direction.
A call to the issuer is underused. Cardholders with on-time histories are sometimes offered a lower rate or a temporary reduction, and the request costs nothing.
The Cases Where Carrying a Balance Is Defensible
Treating every balance as a failure overstates the case. A genuine emergency, such as a medical bill or a car repair that preserves a paycheck, can justify short-term card debt when the alternative is a payday loan or a missed rent payment. A 0% promotional rate with a funded payoff plan is a rational use of credit.
Industry groups make a related argument against rate regulation: they say a hard cap would reduce credit availability and push borrowers toward costlier alternatives such as buy now, pay later firms and payday lenders.
The distinction is between a bounded, planned balance and an open-ended one. The cost of the first is knowable in advance. The second compounds without a stopping point.
What the Policy Debate Means for Cardholders
President Donald Trump called in January for a one-year, 10% cap on credit card interest rates, building on a bipartisan bill from Senators Bernie Sanders and Josh Hawley that would cap rates at 10%.
Matt Schulz, chief credit analyst at LendingTree, has warned that even a smaller cap would likely cut rewards and restrict credit for borrowers with imperfect scores. No cap has taken effect, and the average rate on interest-bearing accounts remains above 22%.
The practical lesson is to plan around the rate on the statement, not the rate in the headlines. A cap may or may not arrive, and its design would determine who keeps access to credit. A balance accruing at 22% today costs the same regardless of what legislation is introduced.
The Bottom Line
The expensive part of a credit card balance is rarely the first month. It is the slow accumulation of interest, lost grace periods, and a utilization ratio that lingers in a credit file. A $5,000 balance repaid in twelve fixed payments costs about $615.
Paying the same balance at the minimum costs about $1,040 and leaves the borrower owing more than $4,400. The difference, roughly $425, is the price of postponing the decision, and it grows with every dollar added to the balance.
