What a bad credit card actually is

A bad credit card — sometimes called a subprime or poor credit card — is a credit card designed for people whose credit score is too low to get approved for a standard card. These cards come with higher interest rates, annual fees, and lower credit limits than cards offered to people with good credit. The trade-off is that the card issuer takes on more risk by lending to someone with a thin or damaged credit history, and they pass that risk back to you through higher costs.

Bad credit cards are real products from real banks and credit unions, not scams. But they are expensive, and the math works against you if you carry a balance. A card marketed to people with scores below 580 might charge 24% to 36% annual interest, compared to 15% to 21% for someone with good credit. That difference adds up fast.

Key Takeaways

  • Bad credit cards charge 20% to 36% interest and often include annual fees of $25 to $99, making them costly if you carry a balance month to month.
  • The main reason to use one is to build credit history — the card reports to all three credit bureaus, and on-time payments improve your score over time.
  • You should only use a bad credit card if you can pay the full balance each month, because interest charges will quickly exceed any credit-building benefit.
  • Secured credit cards, which require a cash deposit, often have lower fees and interest rates than unsecured bad credit cards and work just as well for building credit.
  • Your credit score, income, and whether you have been through bankruptcy all affect which bad credit cards you can get approved for.

Why the interest rates and fees are so high

Banks price credit cards based on risk. If you have a credit score below 600, a history of missed payments, or recent bankruptcy, you represent a higher risk of default — meaning you might not pay the card back. The card issuer compensates for that risk by charging you more.

The annual fee — typically $25 to $99 — is charged just for having the card, whether you use it or not. Some cards also charge a processing fee when you first open the account. These fees are how the issuer recovers money upfront, before you have made any payments. On a card with a $49 annual fee and a $300 credit limit, that fee represents 16% of your entire limit just to own the card for one year.

Interest rates on bad credit cards range from 20% to 36% depending on the issuer and your specific credit profile. If you carry a $500 balance at 28% interest and make only minimum payments, you will pay roughly $140 in interest charges over a year — money that goes to the bank, not toward paying down what you owe.

How bad credit cards build your credit score

The only real advantage of a bad credit card is that it reports to the three major credit bureaus — Equifax, Experian, and TransUnion. When you make on-time payments, those bureaus record the payment history. Over time, a record of on-time payments raises your credit score, even if the interest rate is high.

Your credit score is built from five factors: payment history (35%), amounts owed (30%), length of credit history (15%), credit mix (10%), and new credit inquiries (10%). A bad credit card helps with the first three. Each on-time payment adds to your payment history. As you pay down the balance, your credit utilization — the percentage of your limit that you are using — goes down, which improves your score. And the card itself becomes part of your credit history.

In practice, this means you might see your score rise 50 to 100 points over 6 to 12 months of on-time payments, depending on where you started. That improvement can eventually open doors to better cards, lower interest rates on loans, and better terms on mortgages and auto loans.

Secured cards versus unsecured bad credit cards

You have two main routes if you have bad credit: a secured card or an unsecured bad credit card. The difference matters because it affects your cost and your approval odds.

A secured card requires you to put down a cash deposit, usually $200 to $2,500, which becomes your credit limit. You use the card like any other card, but the bank holds your deposit as collateral. Secured cards typically charge lower interest rates (16% to 24%) and lower annual fees ($0 to $50) than unsecured bad credit cards. They also have higher approval rates because your own money is backing the card. After 6 to 18 months of on-time payments, many issuers will convert the card to unsecured and return your deposit.

An unsecured bad credit card requires no deposit, so you get credit without putting money down. But the issuer takes on more risk, so they charge higher interest (24% to 36%) and higher annual fees ($50 to $99). Approval is harder, and you may be offered a lower credit limit. The trade-off is that you do not have to lock up your own cash upfront.

For most people with bad credit, a secured card is the better choice because the lower fees and interest rates mean you lose less money while building credit. The only reason to choose an unsecured card is if you cannot afford the deposit or if you have already been rejected for secured cards.

What happens if you carry a balance

The math on bad credit cards only works if you pay the full balance each month. If you carry a balance, the interest charges quickly erase any credit-building benefit.

Here is a concrete example: You open a bad credit card with a $500 limit, a $75 annual fee, and 28% interest. You charge $400 and pay only the minimum payment of $25 per month. After one year, you will have paid $300 in minimum payments, but only $100 of that goes toward the balance — the rest goes to interest and the annual fee. You still owe $300, and you have paid $75 in fees plus roughly $112 in interest. Your credit score improved because of on-time payments, but you paid $187 to borrow $400 for a year.

If instead you charged $400 and paid it off in full the next month, you would pay only the $75 annual fee. Your credit score still improves from the on-time payment and low utilization, but you paid one-quarter the cost.

This is why financial counselors recommend bad credit cards only for people who can commit to paying the full balance each month. If you cannot do that, you are paying for credit-building, and the cost is high.

How to use a bad credit card without making it worse

If you open a bad credit card, follow these steps to build credit without digging yourself deeper into debt.

First, charge only what you can pay off in full each month. A good target is to use 10% to 30% of your credit limit — so on a $500 limit, charge $50 to $150 per month. This shows the credit bureaus that you can manage credit responsibly without maxing out the card.

Second, set up automatic payments for the full balance before the due date. Missing even one payment will hurt your score and trigger late fees. Automatic payments remove the risk of forgetting.

Third, do not close the card once your credit improves. Closing it will lower your credit score because it reduces your total available credit and shortens your credit history. Instead, keep it open and use it occasionally for a small charge you pay off when ready.

Fourth, do not explore for multiple bad credit cards at once. Each process triggers a hard inquiry, which temporarily lowers your score. Space out applications by at least six months.

When to move on from a bad credit card

After 6 to 12 months of on-time payments, your credit score should improve enough to may have access to for better cards. Once your score reaches 620 to 650, you become may be able to access for standard cards with lower interest rates and no annual fees.

At that point, you have a choice: keep the bad credit card open and use it occasionally, or stop using it. Closing it will hurt your score slightly, so most people keep it open but dormant. The card issuer may eventually close it if you do not use it for a long time, but that is fine — by then you will have better options.

If your score reaches 700 or higher, you can may have access to for rewards cards or cards with better terms. At that point, the bad credit card has served its purpose and you can move on.

Frequently Asked Questions

Will a bad credit card hurt my credit score when I open it?

Yes, but only temporarily. The hard inquiry from the process lowers your score by a few points for about three months. After that, the card helps your score if you make on-time payments and keep your balance low. The short-term dip is worth it if you use the card responsibly.

Can I get a bad credit card if I have been through bankruptcy?

Yes. Bankruptcy stays on your credit report for 7 to 10 years, but you can open a bad credit card as soon as your bankruptcy is discharged. Some issuers specialize in post-bankruptcy credit, and a secured card is often your easiest path. You will still pay high interest and fees, but the card will help rebuild your credit.

What is the difference between a bad credit card and a prepaid card?

A prepaid card is not a credit card at all — you load money onto it and spend what you loaded. It does not build credit because it does not report to credit bureaus and involves no borrowing. A bad credit card is real credit that you borrow and repay, and it reports to the bureaus. If you want to build credit, you need a bad credit card or secured card, not a prepaid card.

How long does it take to improve my credit score with a bad credit card?

Most people see a 50 to 100 point improvement within 6 to 12 months of on-time payments, depending on where they started. If your score is very low (below 500), it may take longer. The improvement slows after the first year because the credit bureaus weight recent payment history most heavily.

Should I use a bad credit card or a secured card?

A secured card is usually the better choice because it has lower interest rates and fees. The only reason to choose an unsecured bad credit card is if you cannot afford the deposit or have been rejected for secured cards. Both build credit the same way — through on-time payments — so the lower cost of a secured card makes it the smarter option for most people.
