Store financing that promises no interest often has a catch: miss the payoff deadline and interest is charged back to the day you bought the item. Here is how these offers work and what to read before you sign.
This article is general information and isn’t financial or legal advice. Card terms, fees and rules change, so check the issuer’s current terms and official sources such as the Consumer Financial Protection Bureau and the Federal Trade Commission before you decide.
The essentials
- Deferred interest promotions charge no interest only if you pay the promotional balance in full by the end of the period.
- If any balance remains, or you are more than 60 days late on a minimum payment, interest is charged back to the original purchase date.
- These offers are common on store credit cards, which often carry much higher rates than general purpose cards.
- Minimum payments usually are not enough to clear the balance before the promotion expires.
- A true 0% offer, phrased as "0% intro APR," charges interest only on whatever balance remains after the promotional period ends.
At the register or checkout page, a big purchase often comes with a tempting pitch: no interest for 12 months. Many of these offers are not true zero-percent deals. They are deferred interest promotions, and if any balance is left unpaid when the period ends, the interest can be charged back to the day of purchase.
What deferred interest is, and how it differs from a true 0% offer
A deferred interest plan, as the Consumer Financial Protection Bureau (CFPB) defines it, is a plan where you owe no interest on a balance only if you pay that balance in full before a set period expires. If you do not, the interest that built up each month is added to your account, going back to the original purchase date.
A true zero-percent offer works differently. With wording like “0% intro APR for 12 months,” no interest accrues during the promotional period, and when it ends you pay interest only on whatever balance remains. The quickest way to tell them apart is the word “if.” The CFPB warns that the “if” means you could end up paying more than you expected.
| True 0% offer | Deferred interest offer | |
|---|---|---|
| Typical wording | “0% intro APR” | “No interest if paid in full” |
| Interest during the period | None accrues | Accrues, waived only if paid in full |
| Balance left at the end | Interest starts on the remainder | Interest from the purchase date is charged |
| Main risk | Interest on what you still owe | Back-dated interest |
Where these promotions show up
Retailers typically offer deferred-interest promotions on store credit cards to finance larger purchases such as appliances, furniture, electronics, or medical and dental services. The promotional period is typically six to 12 months, and the interest rate on these cards is generally about 25 percent, according to the CFPB.
Store cards are widespread and can be expensive. More than half of the top 100 retailers offer one, and about one in four credit card accounts is a store card, with over 160 million open accounts in 2024. Ninety percent of retail cards reported a maximum APR above 30 percent, compared with 38 percent of general purpose cards, and private label cards for the top retailers averaged 32.66 percent APR in December 2024.
A worked example: what one missed dollar can cost
Suppose you buy a $2,000 sofa on a store card with “no interest if paid in full in 12 months” at about 25 percent APR, the annual percentage rate, or the yearly cost of borrowing. You make the minimum payments on time, but the promotion ends with $200 still unpaid. The problem is not that $200. Interest is calculated on the balance you owed in each month since you bought the sofa, and all of it comes due at once.
Watch for this
Even a small balance left past the promotion’s expiration date can cost more in back-dated interest than the balance still owed. The charge applies to what you owed each month since the purchase, not just what is left.
The fine print: triggers, deadlines and minimum payments
Two things can trigger the deferred interest charge:
- Failing to pay the entire promotional balance by the end of the period.
- Being more than 60 days late on a minimum payment before the period ends. A single late payment can also bring late fees.
Three details deserve special attention:
- The end date. The front page of your billing statement shows when the period ends, and that date can differ from your regular monthly due date.
- The minimum payment. Minimum payments alone usually will not clear the balance in time, the same slow-repayment pattern in our guide to the minimum payment trap.
- How payments are allocated. Amounts above the minimum go to the highest-rate balance first, not necessarily the promotional purchase. Only in the last two billing cycles does everything above the minimum go to the promotional balance.
Using the card for other purchases can also cost you the grace period on them, the window to pay in full and avoid interest, unless you pay the entire card balance by the due date. Our guide to credit card grace periods explains how that protection normally works.
How these promotions are regulated
Deferred interest falls under the credit card rules of the Credit Card Accountability Responsibility and Disclosure Act of 2009, which require issuers to provide repayment disclosures. The CFPB has sent letters to top retail credit card companies encouraging zero-percent promotions instead, calling deferred interest “back-end pricing” that makes potential costs confusing and less transparent. At least one major U.S. retailer has since announced it will replace deferred-interest promotions with a true zero-percent promotional period.
Questions to ask before you sign up
Before accepting a promotional financing offer, ask:
- Is this a true “0% intro APR” offer, or a “no interest if paid in full” deferred interest plan?
- What is the regular APR once any promotion ends?
- Will the minimum payment clear the balance in time? Dividing the purchase price by the number of months shows what it would take.
- What happens if a payment is late, and what fees apply?
A deferred interest promotion can work out if the balance can be paid in full before the deadline, with room to spare. If the plan depends on perfect timing, compare other options, including the pay-in-4 installment plans in our guide to buy now, pay later.
Questions and answers
How is deferred interest different from a 0% intro APR offer?
A 0% intro APR offer charges no interest during the promotion, and when it ends you pay interest only on the balance still remaining. A deferred interest promotion erases the interest only if you pay the balance in full by the deadline; otherwise that interest is added retroactively.
Can one late payment trigger the deferred interest charge?
Being more than 60 days late on a minimum payment before the promotional period ends can cause you to lose the promotion and owe the back-dated interest. A single late payment can also bring late fees and other consequences.
Why did I owe interest even though I paid more than the promotional balance?
If you had other purchases on the same card, payments above the minimum go first to the balance with the highest rate, which may not be the promotional balance until the last two billing cycles. The Consumer Financial Protection Bureau has found that many people who owe deferred interest charges actually paid more than their full promotional balance during the period.
Are deferred interest offers still common?
They are still widely used on store cards for large purchases, though the Consumer Financial Protection Bureau has pushed retailers toward more transparent zero-percent promotions, and at least one major retailer has announced it would drop deferred-interest offers in favor of true 0% periods.
