How Best Buy's Payment Plans Work and What They Cost
Best Buy offers payment plans through its store card, but the terms depend on the purchase amount and the plan you choose
Best Buy's payment options come through its Best Buy credit card, which is issued by Citi. When you use the card at Best Buy, you can get promotional financing on certain purchases — typically zero percent interest for a set number of months if you pay off the balance within that window. The catch is that these offers are not automatic; they apply only to specific items or purchase amounts, and you have to may have access to for the card first.
The most common offer is 12 months special financing on purchases of $399 or more, though Best Buy runs different promotions throughout the year. Some items — like laptops, appliances, or gaming systems — may have their own promotional terms. If you do not pay off the full balance before the promotional period ends, the card's regular interest rate (which varies based on your creditworthiness) kicks in on the remaining balance, and you owe interest retroactively on the entire purchase.
Best Buy also offers no-interest installment plans through a third-party lender called Affirm, which is separate from the store card. Affirm lets you split a purchase into monthly payments over three, six, or twelve months with no interest — but only if you meet Affirm's approval, which depends on your credit and income. Affirm charges Best Buy a fee, not you, so the cost to you is zero if you pay on time.
Key Takeaways
- Best Buy's store card offers zero-percent financing for 12 months on purchases of $399 or more, but interest applies retroactively if you miss the deadline.
- Affirm is a separate payment option that splits purchases into three, six, or twelve monthly payments with no interest, though you must be approved by Affirm first.
- Promotional financing terms change throughout the year, so the offer you see today may not be the same next month.
- Missing a payment or paying late on either option can trigger late fees and damage your credit score.
- The store card's regular interest rate applies to any balance you carry beyond the promotional period, and that rate is not fixed.
How the Best Buy Store Card's Promotional Financing Works
When you open a Best Buy credit card, you are applying for a standard credit card issued by Citi. The card itself has an interest rate (called the APR, or annual percentage rate) that depends on your credit score and history. But Best Buy advertises promotional offers — usually zero percent interest for a certain number of months — that override that rate for may have access to purchases.
To get the promotional rate, you must make a purchase that meets the minimum amount (often $399) and the item must be may be able to access. Not everything at Best Buy qualifies; the store typically excludes gift cards, services, and some clearance items. When you check out, the cashier or website will tell you whether your purchase qualifies and what the terms are.
The promotional period is a hard deadline. If you owe any balance when it ends, the regular card APR applies to that remaining balance — and here is the critical part: you owe interest on the entire original purchase amount, not just the remaining balance. This is called deferred interest. For example, if you buy a $500 laptop with 12 months zero percent financing and pay $400 by month 12, you owe interest on the full $500 for all 12 months, not just the $100 you still owe.
Affirm: A Different Path to Monthly Payments
Affirm is a buy-now-pay-later service that Best Buy offers as an alternative to the store card. Instead of opening a credit card account, you use Affirm at checkout to split your purchase into equal monthly payments. Affirm offers three, six, or twelve-month plans, and if you are approved, there is no interest on any of them.
Affirm checks your credit and income when you apply, but the approval process is usually instant or takes a few minutes. Unlike the store card, Affirm does not report to the three major credit bureaus (Equifax, Experian, TransUnion) as a credit account, so using Affirm does not build credit history the way a credit card does. However, missing a payment to Affirm can still hurt your credit because Affirm may report the delinquency to the bureaus.
The advantage of Affirm over the store card is simplicity: you know your payment amount upfront, there is no risk of retroactive interest, and you do not have to manage a credit card account. The disadvantage is that you do not build credit, and if Affirm denies you, you cannot use that payment method for that purchase.
What Happens If You Miss a Payment or Pay Late
Missing a payment on either the Best Buy card or Affirm has immediate consequences. Both will charge a late fee — typically $25 to $40 depending on the lender — and both will report the late payment to the credit bureaus. A single late payment can lower your credit score by 50 to 100 points, and the damage gets worse the longer the account stays delinquent.
On the Best Buy card, a late payment also triggers the end of any promotional financing period. If you were in the middle of a 12-month zero-percent offer and you miss a payment, the promotional rate ends immediately, and the regular APR applies to your entire balance retroactively. This can turn a $500 purchase into a much larger debt very quickly.
With Affirm, a missed payment does not end the plan, but Affirm will contact you to collect and may pursue the debt through a collection agency if you do not pay. Both lenders can sue you in small claims court if the debt is large enough and remains unpaid.
Comparing the Store Card to Affirm and Other Options
| Feature | Best Buy Store Card | Affirm | Regular Credit Card |
|---|---|---|---|
| Interest on promotional purchases | 0% for set period (usually 12 months) | 0% for all plans | Varies; typically 15–25% |
| Retroactive interest if you miss deadline | Yes | No | N/A |
| Builds credit history | Yes | No | Yes |
| Approval time | Minutes to hours | Instant to minutes | Minutes to hours |
| Can use outside Best Buy | Yes | At select retailers only | Anywhere |
If you do not want to open a new credit card account, Affirm is the simpler choice because there is no interest risk and no credit card to manage. But if you plan to shop at Best Buy regularly, the store card offers a lower barrier to zero-percent financing and builds your credit score with on-time payments.
If you already have a credit card with a low interest rate, paying cash or using your existing card may be cheaper than either option — especially if you cannot may provide you will pay off the balance before the promotional period ends. The store card's retroactive interest trap is real and expensive.
How to Avoid the Retroactive Interest Trap
The biggest risk with the Best Buy store card is deferred interest. To avoid it, treat the promotional period as a hard deadline and set a reminder on your phone or calendar for one month before it ends. Pay off the entire balance before that date, not on the last day.
If you are not confident you can pay off the full amount within the promotional window, use Affirm instead. Affirm's monthly payments are fixed and there is no interest penalty if you pay on time, so the math is simpler and the risk is lower.
Before you open the Best Buy card, read the terms carefully. Best Buy's website and the card issuer (Citi) will show you the APR range you might receive based on your credit, the promotional offers currently available, and the exact terms of each offer. Do not assume that every purchase qualifies or that the offer you see today will still be available next week.
Frequently Asked Questions
Can I use the Best Buy card outside of Best Buy?
Yes. The Best Buy card is a Citi credit card, so you can use it anywhere Visa is accepted. However, the promotional financing offers (zero percent for 12 months, etc.) apply only to purchases made at Best Buy or on Best Buy's website. Purchases elsewhere carry the regular card APR.
What is the interest rate on the Best Buy card if I do not get a promotional offer?
The APR varies based on your credit score and history. Citi publishes a range (typically 18% to 27%), but your exact rate depends on your creditworthiness. You will see your rate before you finish opening the account.
Can I pay off my Affirm plan early without a penalty?
Yes. Affirm allows early payoff with no penalty or extra fees. If you pay off the full balance before the plan ends, you are done — there is no interest charged for the months you skip.
Does Affirm report to credit bureaus?
Affirm does not report on-time payments to the credit bureaus, so using Affirm does not build your credit score. However, Affirm will report late or missed payments, which can hurt your credit.
What happens if I am denied for the Best Buy card or Affirm?
If you are denied for the store card, you can still shop at Best Buy but you will pay the regular price with no financing options. If Affirm denies you, you can try the store card or pay in full. Some Best Buy locations also offer in-store financing through other lenders, so ask a cashier what options are available.
