Store credit cards and general-purpose credit cards both work as revolving credit. You buy now and pay over time. The incentives behind them differ, though, and so do the pricing and the interest rate ceilings.

Understanding the core structural differences

The Consumer Financial Protection Bureau defines general-purpose credit cards as open-end loans used to pay for day-to-day expenses, finance purchases, or get cash advances. Store cards are different. The CFPB's issue spotlight describes private label and co-branded cards as retail or store credit cards, offered in a partnership between a retailer and a major issuer.

So the retailer's name is on the card, but a partner issuer is part of the deal. The offer often shows up when you shop, online or in the store, and it usually comes with a discount for signing up. That is a moment when many people decide fast. The sign-up sheet at the register is worth a slow read before you say yes. It tells you what you are agreeing to.

Market presence and cardholder demographics

Store cards are a big part of consumer borrowing. The CFPB reports that over half of the top 100 retailers offer some type of store card with a major issuer, even though store card use has declined in recent years. In 2024 there were over 160 million open store card accounts.

They are especially common among people with lower credit scores. One in four credit card accounts is a store card. For consumers with subprime scores, the figure is closer to one in three. For many people, then, a store card is a main way into revolving credit, not a side product.

Interest rate structures and maximum APR ceilings

The sharpest contrast is the rate ceiling. The CFPB found that 90 percent of retail cards report a maximum APR above 30 percent. Among non-retail general-purpose cards, 38 percent do.

Many private label cards also use a fixed APR. Every cardholder pays the same rate, no matter their creditworthiness. A flat rate is simple to read. But it also means a person with strong credit gets no lower rate for it.

Two questions are worth asking before you open an account:

  • Is the APR fixed or variable, and what is the maximum APR?
  • Does the offer involve deferred interest or a promotional rate?

Then compare the card's maximum APR with the rate on a general-purpose card you already hold or could qualify for. Put the two numbers side by side. The gap is the cost of the checkout discount if you ever carry a balance.

Promotions, incentives, and what the sources leave out

The CFPB's Consumer Credit Card Market report examines deferred interest, promotional interest rates, and merchant category spending. The excerpts we reviewed do not spell out how those terms work in a given contract, so check the card agreement for them. Look for any promotional period, and for what happens to interest when it ends.

The CFPB issue spotlight also says the partnership between merchant and issuer can create incentives that pose potential risk to consumers. Revenue from these products can significantly affect the companies' profits. That gives both sides a reason to promote the card at checkout.

Some things the sources do not cover. They do not compare fees, rewards, or approval standards between store and general-purpose cards. They do not say how a store card affects a credit score or report. They do not describe protections specific to store cards, such as dispute rights. Anyone weighing a card on those points will need to read the issuer's own terms.

Broader market numbers give some context. As reported by the ABA Banking Journal, credit card purchase volume reached $3.6 trillion in 2024, up from $3.2 trillion two years earlier, and balances topped $1.2 trillion. Year-end 2024 delinquency rates were 3 percent for general-purpose cards and 3.8 percent for private-label cards. Cardholders disputed $9.8 billion in charges in 2024, which resulted in $5.9 billion in chargebacks.

The takeaway is practical. Read the rate, check whether it is fixed, ask about deferred interest, and compare against a general-purpose card before you sign.
