The Best Buy card makes sense only if you shop there regularly and pay the full balance every month

The Best Buy credit card offers 5% back on Best Buy purchases and 1% back on everything else, but those rewards disappear the moment you carry a balance. The card's interest rate runs 21.99% to 28.99% depending on your credit score, which means a single month of unpaid charges can wipe out a year of rewards. If you pay in full each month and spend at least $500 annually at Best Buy, the card can save you real money. If you carry a balance or shop there only occasionally, a cash-back card with no annual fee and a lower interest rate will cost you less.

The decision comes down to three things: how much you actually spend at Best Buy, whether you can pay the bill in full each month, and what other cards you already have. This guide walks through the math so you can see whether the card works for your situation.

Key Takeaways

  • The 5% Best Buy reward only saves money if you pay the full statement balance by the due date every month—one missed payment erases years of rewards.
  • You need to spend roughly $1,000 per year at Best Buy for the rewards to beat a standard 2% cash-back card with no annual fee.
  • The card charges 21.99% to 28.99% interest, which is typical for retail cards but higher than many bank-issued cash-back cards.
  • Best Buy also offers a store credit card and a Visa version; the Visa has better rewards outside Best Buy but costs more in interest if you slip up.

How the rewards actually work

The Best Buy card gives you 5% cash back on purchases at Best Buy and 1% cash back on everything else. That sounds straightforward, but the catch is that you only get the reward if you pay the full balance by the due date. If you carry even $100 into the next month, you pay interest on the entire balance at the card's standard rate, which ranges from 21.99% to 28.99%. A single month of interest will cost you more than months of 5% rewards.

The card has no annual fee, so there is no yearly cost just to hold it. However, Best Buy also offers a store credit card (which works only at Best Buy) and a Best Buy Visa (which works everywhere). The Visa version has slightly better rewards outside Best Buy but carries the same interest rate risk. If you are choosing between them, the Visa makes sense only if you spend significant money outside Best Buy and can may provide you will never carry a balance.

When the 5% reward actually saves you money

To figure out whether the card is worth it, compare it to a standard 2% cash-back card with no annual fee. If you spend $1,000 per year at Best Buy, the Best Buy card gives you $50 back. A 2% card gives you $20 back. The Best Buy card wins by $30. But that advantage only exists if you never carry a balance.

The math changes if you carry a balance even once. Suppose you charge $500 to the Best Buy card and pay it off over two months instead of one. At 25% interest (the middle of the card's range), you will pay roughly $21 in interest charges. Your 5% reward on that $500 is $25, so you come out $4 ahead—but only barely, and only if you catch yourself and pay it off quickly. If you carry the balance for three months, the interest cost exceeds the reward.

The realistic threshold is this: if you spend less than $1,000 per year at Best Buy, or if you have ever carried a credit card balance, a standard cash-back card will cost you less. If you spend $2,000 or more per year at Best Buy and you have a track record of paying in full every month, the Best Buy card can save you $30 to $60 per year.

Interest rates and what happens if you miss a payment

The Best Buy card's interest rate is 21.99% to 28.99%, depending on your credit score at the time you open the account. That is typical for retail credit cards but higher than many bank-issued cards, which often start at 18% to 24%. The difference matters if you ever carry a balance.

If you miss a payment, the card will charge a late fee (typically $25 to $40 for the first late payment) and may raise your interest rate to the penalty rate, which can be as high as 29.99%. Your credit score will also drop, which affects your ability to borrow money for other things. Missing even one payment wipes out years of rewards and costs you far more than you saved.

Comparing the Best Buy card to other options

If you want cash back on tech purchases, you have other choices. A general 2% cash-back card (like the Citi Double Cash or Capital One Quicksilver) gives you 2% back on everything, including Best Buy, with no annual fee and often a lower interest rate. You lose the extra 3% at Best Buy, but you gain flexibility and a lower penalty if you slip up.

Some cards offer 3% to 5% cash back on specific categories like electronics or online shopping, which might cover Best Buy depending on how the card defines those categories. Check the card's terms to see whether Best Buy counts as "electronics" or "online shopping" for the higher rate. If it does, that card might beat the Best Buy card even if you carry a balance occasionally, because the interest rate is usually lower.

If you shop at Best Buy frequently and also use other retailers, the Best Buy Visa version offers 3% back at gas stations and restaurants and 1% everywhere else, plus the 5% at Best Buy. That makes it more flexible than the store-only card. But again, the advantage only exists if you pay in full every month.

What to do before you open the account

Before you explore, check your credit score. You can see it free through your bank's website, through a service like Credit Karma, or by requesting it from Equifax, Experian, or TransUnion. The Best Buy card's interest rate depends on your score, so knowing it in advance tells you whether you will be at the low end (21.99%) or high end (28.99%) of the range.

Next, add up what you actually spent at Best Buy over the past year. Look at your credit card or bank statements for the last 12 months and total it. If the number is under $1,000, the card is unlikely to save you money. If it is over $2,000 and you have never carried a balance, the card is worth considering.

Finally, be honest about your payment habits. If you have ever paid a credit card bill late, or if you sometimes carry a balance to spread out a large purchase, the Best Buy card will cost you more than it saves. A lower-interest card with a lower reward rate is the safer choice.

Frequently Asked Questions

Does the Best Buy card have an annual fee?

No, there is no annual fee. You can hold the card without using it and pay nothing. However, Best Buy may close the account if it sits unused for a long time, which can affect your credit score.

Can I use the Best Buy card outside Best Buy?

The store credit card works only at Best Buy. The Best Buy Visa works everywhere but gives you only 1% cash back outside Best Buy, compared to 5% at Best Buy. A standard 2% cash-back card will give you more back on non-Best Buy purchases.

What happens to my rewards if I carry a balance?

You still earn the cash-back rewards, but the interest you pay will exceed them. If you charge $500 and carry it for three months at 25% interest, you will pay roughly $31 in interest but earn only $25 in rewards. You lose money overall.

Will opening this card hurt my credit score?

Opening any credit card will lower your score slightly because it creates a hard inquiry and lowers your average account age. The impact is usually 5 to 10 points and recovers within a few months. Carrying a balance or missing a payment will hurt your score far more.

Can I use the Best Buy card for a financing offer?

Best Buy offers promotional financing (like 12 months interest-free on purchases over a certain amount) to cardholders and non-cardholders alike. The card itself does not unlock special financing, but using the card for a promotional purchase may make the process faster. Read the terms carefully, because if you do not pay off the balance by the end of the promotional period, you will owe all the interest that accrued during that time.
