What if my card still charges interest on a disputed amount?

This notice

Your credit card statement, app screen, or letter still shows interest, finance charges, or related fees on an amount you already disputed in writing as a billing error.

This is not LIVE credit-card-dispute-denied. That guide starts when the issuer finished its review and said no error was found, or reversed a provisional credit. This page starts when interest or fees are still posting on the disputed dollars themselves.

This is not LIVE capital-one-deferred-interest-billed. Deferred-interest promo language is a different product notice. Keep that page for expired promo interest on a store or promo card. Keep this page for interest tied to a billing-error dispute.

The CFPB page Can they charge me interest on a charge I told them I did not make? says that if you gave the card issuer written notice of the billing dispute, you do not have to pay the amount in dispute while it investigates, and the card issuer cannot charge interest on that amount. The same page says that if you pay the rest of the bill, you stay entitled to a grace period on new purchases.

The CFPB guide How to fix mistakes in your credit card bill repeats the same rule in plain steps: while the company investigates, it cannot charge you interest on the disputed charge or make you pay that charge. You must still pay the undisputed part on time.

Recent CFPB complaint themes describe issuers that kept finance charges on fraud or billing-error disputes, provisional credits that omitted related interest, and statements that still demanded payment of the disputed slice. Forum threads about “interest while my dispute is open” track the same pattern. Official Ask and how-to pages win any tip that says you must pay the full statement—including the disputed part—or lose the dispute.

Official path

1. Save the statement that shows the disputed charge and the interest or fee lines, your written dispute or billing-error letter, mailing or portal proof, claim numbers, and any emails. Write the statement date and the date you first disputed.

2. Check that your dispute was written and timely. The Ask page How do I dispute a charge on my credit card bill? says to send a written billing-error notice within 60 calendar days after the charge appeared on your statement, to the address for billing errors—not the payment address. If you only called, send the written notice now if you are still inside that window.

3. Pay every amount you do not dispute by the due date. The interest Ask page and the how-to-fix guide both say you should pay the undisputed part on time. That protects your grace period on new purchases and avoids late reporting on amounts that were never in dispute.

4. Write again if interest or fees still post on the disputed amount. Say you already sent a written billing-error notice, list the disputed charge, list each interest or fee line you say is tied to it, and ask the issuer to reverse those finance charges and confirm in writing that it will not collect interest on the disputed amount while the investigation is open. Mail it to the billing-error address. Keep a copy.

5. Compare the reply to Regulation Z billing-error rules. § 1026.13 covers billing-error resolution. The how-to-fix page says the company generally has 30 days to acknowledge your letter and two billing cycles (no more than 90 days) to finish looking into it.

6. Submit a CFPB complaint if the issuer keeps charging interest on the disputed amount, demands payment of that amount while the dispute is open, or never answers your written notice. Attach statements, your dispute letters, and proof you paid the undisputed balance.

People on forums sometimes say “just pay the whole bill so they take you seriously.” The CFPB interest Ask page wins that conflict: after written notice, you do not have to pay the disputed amount during the investigation, and the issuer cannot charge interest on it.

What people reported

Often helps

• Sending a short written follow-up that names the disputed charge, the interest or fee lines, and the date of the first written dispute, then paying only the undisputed balance by the due date.
• Escalating with a CFPB complaint when statements keep adding finance charges to the disputed slice after the issuer already logged a billing-error case.

Often fails

• Disputing only by phone and never mailing to the billing-error address, then having no proof when interest keeps posting.
• Paying the disputed amount “to stop the interest,” then losing leverage and still waiting months for a refund. Reddit and credit-card forum themes about interest during an open dispute were partly reachable via public search; CFPB complaint themes about finance charges on disputed amounts match. Official Ask and how-to pages win any conflict.

Re: Billing error — interest and fees on disputed amount / Account ending [LAST FOUR]

On [DATE] I sent a written billing-error notice about the charge of $[AMOUNT] dated [DATE] from [MERCHANT OR DESCRIPTION]. That dispute is still open.

My statement dated [DATE] still shows interest, finance charges, or related fees tied to that disputed amount, including: [LIST LINES AND AMOUNTS].

Under the Fair Credit Billing Act and Regulation Z, after written notice I do not have to pay the disputed amount while you investigate, and you may not charge interest on that amount. I am paying the undisputed balance of $[AMOUNT] by the due date.

Please:
1. Reverse all interest, finance charges, and related fees assessed on the disputed amount while the dispute is pending.
2. Confirm in writing that you will not collect the disputed amount or interest on it until the investigation is finished.
3. Send a corrected statement and your written finding when the investigation ends.

Enclosures: prior dispute letter, statement pages, proof of undisputed payment.

Stop here if…

• The issuer already finished the investigation and said no error was found, or reversed a provisional credit. Use the credit-card-dispute-denied guide.
• The paper is deferred-interest promo billing after a store or promo period ended. Use the capital-one-deferred-interest-billed guide.
• The problem is a bank checking or debit Reg E claim, not a credit-card billing error. Use the wells-fargo-unauthorized-transaction-denied guide.
• The issuer owes you a credit-balance refund it never sent. Use the credit-card-credit-balance-refund-not-sent guide.
• You never opened the card at all. Use the credit-card-opened-without-consent guide and IdentityTheft.gov.

FAQ

Is this the same as a dispute-denied letter?

No. The credit-card-dispute-denied guide is for a finished investigation letter that says no error was found or that reverses a provisional credit. Keep this page when the live problem is interest or fees still posting on an amount you already disputed in writing.

Do I still have to pay anything?

Yes. The CFPB Ask page Can they charge me interest on a charge I told them I did not make? says you do not have to pay the disputed amount while the issuer investigates. You should still pay the rest of the bill on time. If you pay everything except the disputed amount, that page says you stay entitled to a grace period on new purchases.

Does a phone dispute count?

Call to flag the problem fast, but protect your rights with a written billing-error notice. The CFPB page How do I dispute a charge on my credit card bill? says you must also send written notice within 60 calendar days after the charge appeared on your statement, to the billing-error address on the statement.

What if the issuer later says the charge was correct?

The how-to-fix-mistakes page says the company must tell you why, how much you owe, and when payment is due if it decides all or some of the charge is correct. That finished denial letter is a different notice. Use the dispute-denied guide for that paper and still ask them to reverse any interest that was wrongly billed while the dispute was open if the facts support it.

Does this cover a bank checking Reg E claim?

No. Unauthorized debit-card or bank-account transfers use a different path. Use the wells-fargo-unauthorized-transaction-denied guide when a bank denied an electronic-fund-transfer claim. This page is about credit-card billing errors and interest on the disputed card amount.
