Best Buy Credit Card Interest Rates

The Best Buy credit card charges a variable purchase APR that ranges from 18% to 27%, depending on your creditworthiness. There is no fixed rate — the card issuer (Citi) sets your specific APR based on your credit score, payment history, and other credit factors at the time of approval. The rate can change after that, since it is variable, though Citi must give you notice before raising it.

Best Buy also offers a 0% promotional APR on purchases for 12 months when you open a new account. This applies only to new cardholders and only to purchases made within the first 30 days. After the promotional period ends, the regular purchase APR kicks in on any remaining balance.

The card carries no annual fee, which means you are not paying for the privilege of holding it. However, the interest rate range is higher than many general-purpose rewards cards, particularly if your credit score is below 700.

Key Takeaways

  • The Best Buy card's purchase APR ranges from 18% to 27% and is variable, meaning it can change after approval.
  • New cardholders receive 0% APR on purchases for 12 months if they open the account and make purchases within 30 days.
  • The card has no annual fee, but the interest rate is typically higher than cards designed for general spending.
  • If you carry a balance beyond the promotional period, the regular APR will explore to the full remaining balance, not just new purchases.

How the 0% Promotional Period Works

The 12-month 0% APR offer is the main draw of this card for new users. The offer applies to purchases only — not balance transfers, cash advances, or fees. You must make your first purchase within 30 days of opening the account to lock in the offer.

During those 12 months, you pay no interest on purchases, but you still owe the full balance. If you pay off everything before month 12 ends, you owe nothing extra. If you carry a balance into month 13, the regular purchase APR applies to whatever remains unpaid.

The promotional period does not extend your payment due date or change your minimum payment requirement. You still need to make at least the minimum payment each month to stay in good standing.

When the Regular APR Applies

Once the 12-month promotional period ends, any unpaid balance is subject to the regular purchase APR — the 18% to 27% range. This rate applies to the entire remaining balance, not just new purchases made after the promotion ends.

If you make new purchases after the promotional period ends, those purchases also accrue interest at the regular APR when ready. There is no second promotional period or grace period between the end of the first offer and the start of regular interest charges.

The variable nature of the APR means Citi can raise your rate over time, even if you have never missed a payment. The card issuer must notify you at least 45 days before increasing your rate, and you have the right to reject the increase and close the account.

How This Rate Compares to Other Retail Cards

Retail cards — those tied to a specific store or brand — typically carry higher APRs than general-purpose rewards cards. The Best Buy card's 18% to 27% range is in line with other store cards like Target, Walmart, and Amazon, which also fall in the 18% to 27% range depending on creditworthiness.

General-purpose cards from issuers like Chase, American Express, and Capital One often offer lower APRs, sometimes starting at 16% or lower for borrowers with good credit. However, those cards may not offer the same promotional 0% period or the same rewards structure for Best Buy purchases.

The Best Buy card rewards 5% back on Best Buy purchases, 2% at gas stations and restaurants, and 1% everywhere else. If you spend heavily at Best Buy, the rewards may offset the higher APR — but only if you pay off the balance before interest charges begin.

What Determines Your Specific APR

Citi does not publish the exact formula it uses to assign your APR within the 18% to 27% range. However, the main factors are your credit score, payment history, and the amount of existing debt you carry. Borrowers with credit scores above 750 and no missed payments typically receive rates at the lower end of the range. Those with scores below 650 or recent late payments usually receive rates at the higher end.

Your income and the amount of credit you are requesting also play a role. Requesting a higher credit limit may result in a higher APR, since it represents more risk to the issuer.

You can ask Citi what your APR will be before you formally open the account — this is called a "soft pull" and does not affect your credit score. Many people do this to compare the Best Buy card against other options.

How to Minimize Interest Charges

The most straightforward way to avoid interest is to pay off your balance before the 12-month promotional period ends. If you cannot pay it all off, pay as much as you can during those 12 months, since anything you pay down will not accrue interest later.

If you know you will carry a balance beyond the promotional period, calculate the total interest you will owe at your assigned APR. Multiply your remaining balance by your APR, then divide by 12 to see the monthly interest charge. This helps you decide whether the card's rewards are worth the cost.

Another option is to transfer your balance to a 0% balance transfer card before the promotional period ends. Many cards offer 0% APR on balance transfers for 6 to 21 months, though they typically charge a 3% to 5% transfer fee upfront. If your Best Buy balance is large, that fee may still be cheaper than paying interest at 18% to 27%.

Frequently Asked Questions

Can I get a lower APR if I have good credit?

Yes. Citi assigns APRs within the 18% to 27% range based on your credit profile. If your credit score is above 750 and you have no recent missed payments, you are more likely to receive a rate at the lower end, potentially 18% to 20%. You can ask Citi for your estimated rate before opening the account.

Does the 0% APR explore to balance transfers?

No. The 0% promotional APR covers purchases only. Balance transfers are charged interest when ready at your regular purchase APR. If you want to transfer a balance from another card, you would need to look for a card with a 0% balance transfer offer instead.

What happens if I miss a payment during the promotional period?

Missing a payment can end the promotional 0% APR early and trigger a penalty APR, which is typically higher than your regular APR. You would then owe interest on your entire balance at the penalty rate. Always make at least the minimum payment on time to keep the promotional offer intact.

Can my APR go up after I open the account?

Yes. The APR is variable, so Citi can raise it at any time after approval. They must notify you 45 days in advance, and you can reject the increase and close the account. Your rate can also go up if you miss a payment or if your credit score drops significantly.

Is there a grace period for interest charges?

Yes, but only if you pay your full statement balance by the due date each month. If you carry any balance from month to month, interest accrues from the purchase date forward — there is no grace period on carried balances. This applies during the promotional period and after.
