The difference comes down to what backs the card
A secured credit card requires you to put down a cash deposit that the card issuer holds as collateral. That deposit becomes your credit limit — if you deposit $500, you get a $500 limit. An unsecured credit card requires no deposit. The issuer extends credit based on their assessment of your creditworthiness, and you pay interest on any balance you carry.
The secured card exists because it reduces the issuer's risk. If you stop paying, they keep your deposit. This is why secured cards are the standard first step for people rebuilding credit or starting from scratch. Unsecured cards are what most people use once their credit history is established enough that lenders will take the risk without collateral.
The card itself looks and works the same way — you swipe it, you get a statement, you pay a bill. The difference is invisible to the merchant and to you at the register. It only matters to the issuer and to your credit-building strategy.
Key Takeaways
- Secured cards require a cash deposit held by the issuer; unsecured cards do not require any deposit upfront.
- Your deposit amount directly sets your credit limit on a secured card, while unsecured cards set limits based on credit history and income.
- Secured cards typically charge higher interest rates and annual fees than unsecured cards because the issuer is taking on more risk.
- Most secured cards allow you to graduate to an unsecured card after 12 to 24 months of on-time payments, at which point your deposit is returned.
How the deposit works on a secured card
When you open a secured card, you send the issuer a deposit — usually between $200 and $2,500, depending on the card and the issuer's requirements. That money sits in a savings account the issuer controls. You cannot touch it while the card is open. It is not your credit limit; it is collateral.
Your credit limit equals your deposit amount. If you deposit $1,000, you can charge up to $1,000 on the card. If you want a higher limit later, you deposit more money. Some issuers will increase your limit without requiring additional deposits after you have made on-time payments for several months, but this varies by card.
The deposit earns little to no interest — usually 0.01% or less. You are paying for the privilege of building credit, not for a savings account. The real cost is the annual fee (typically $25 to $95) and the interest rate (usually 18% to 24% if you carry a balance).
Why unsecured cards have stricter approval requirements
An unsecured card issuer has no collateral to fall back on. If you default, they lose money. This is why they scrutinize your credit report, income, and payment history before approving you. Most unsecured cards require a credit score of at least 670, though some require 700 or higher. Many also require proof of income.
A secured card issuer faces much lower risk because they hold your deposit. This is why secured cards are offered to people with no credit history, recent defaults, or scores below 600. The deposit is the security; your credit history is secondary. Some issuers require only a Social Security number and a deposit to open a secured card.
This difference in approval standards is why secured cards are the entry point for credit building. You do not need a good credit score to get one. You need a deposit and a willingness to use the card responsibly.
Interest rates and fees: what each type typically costs
Secured cards almost always charge higher interest rates than unsecured cards. A typical secured card carries an APR between 18% and 24%. An unsecured card for someone with good credit might be 12% to 18%. This higher rate reflects the issuer's assumption that secured-card users are riskier borrowers.
Annual fees also differ. Secured cards commonly charge $25 to $95 per year. Some unsecured cards charge no annual fee at all, especially if you have good credit. A few unsecured cards aimed at people rebuilding credit charge $25 to $50 annually, but this is less common.
The math matters if you carry a balance. On a $1,000 balance at 20% APR, you pay roughly $200 in interest over a year. On the same balance at 15% APR, you pay roughly $150. Over time, even a few percentage points add up. This is why the goal with a secured card is to pay the full balance each month and avoid interest charges altogether.
When a secured card graduates to unsecured
Most secured cards are designed as stepping stones, not permanent products. After 12 to 24 months of on-time payments, the issuer will review your account and may convert it to an unsecured card. When this happens, your deposit is returned to you — usually within one to two weeks — and your credit limit is set by the issuer based on your payment history and income.
Graduation is not automatic. You have to meet the issuer's criteria: typically 12 to 24 consecutive on-time payments, a low balance-to-limit ratio (ideally below 10%), and no late fees or disputes. Some issuers will graduate you after 12 months; others require 24. A few require you to request the conversion; others do it on their own.
When you graduate, your credit limit may stay the same, increase, or decrease depending on the issuer's assessment. Your interest rate and annual fee may also change. Read the issuer's offer carefully before accepting the conversion, because you are moving into a different product with different terms.
How to know which type you are looking at
The card's marketing materials or product page will state clearly whether it is secured or unsecured. Look for language like "requires a security deposit" or "deposit-backed" for secured cards. Unsecured cards will say "no deposit required" or straightforward not mention a deposit at all.
If you are unsure, check the issuer's website or call their customer service line. The distinction is fundamental to how the card works, so any legitimate issuer will explain it upfront. If a card's website is vague about whether a deposit is required, that is a red flag — move on to a clearer option.
You can also infer the type from the context. If you are looking at cards specifically marketed for people rebuilding credit or with no credit history, they are almost certainly secured. If you are looking at cards marketed to people with good credit, they are almost certainly unsecured.
Frequently Asked Questions
Can I use my deposit as a payment if I miss a bill?
No. Your deposit is collateral, not a payment source. If you miss a payment, the issuer reports it to credit bureaus and may charge a late fee, but they do not automatically take money from your deposit. You must make your payment separately. If you default completely, the issuer may eventually explore your deposit to the debt, but this happens only after collection efforts.
What happens to my deposit if I close the card early?
Most issuers return your deposit within one to two weeks of closing the account, as long as you have paid off any remaining balance. Some may hold it longer if there are pending disputes or chargebacks. Check your card's terms for the exact timeline. Do not close the card when ready after paying it off — wait at least a few months to show the issuer you can manage the account responsibly.
Can I increase my credit limit on a secured card without depositing more money?
Some issuers will increase your limit after several months of on-time payments without requiring an additional deposit. Others require you to deposit more money to raise your limit. This varies by issuer and by card. Contact your issuer to ask about their policy — it is usually outlined in your cardholder agreement or available on their website.
Do secured and unsecured cards build credit the same way?
Yes. Both report to the three major credit bureaus and both build credit history through on-time payments, low balances, and account age. The only difference is the deposit requirement. From a credit-building perspective, a secured card works just as well as an unsecured card — the deposit is purely a risk-management tool for the issuer.
Should I get a secured card if I have fair credit?
If your score is above 620 and you have some credit history, you may be able to get an unsecured card instead. Unsecured cards for fair credit typically charge higher interest rates and fees than cards for good credit, but they avoid the deposit requirement. Compare the terms of both options — sometimes an unsecured card with a higher APR costs less overall than a secured card with a deposit and annual fee.
