What a chargeback is
A chargeback is a reversal of a transaction that your bank initiates on your behalf. When you report a charge you didn't make or a purchase that went wrong, your bank can contact the merchant's bank and demand the money back. The merchant's bank then pulls the funds from the merchant's account and returns them to you — usually within two to three weeks, though the full process can take up to 90 days.
Chargebacks exist because credit and debit card networks (Visa, Mastercard, Discover, American Express) built in a safety mechanism: if a merchant won't refund you, your bank can force the issue. This is different from asking the merchant directly for a refund. A chargeback is your bank stepping in when the merchant doesn't cooperate or when you can't reach them.
Key Takeaways
- A chargeback is a forced refund your bank requests from the merchant's bank when you dispute a charge.
- You typically file a chargeback through your bank's dispute process, not by contacting the merchant directly.
- The merchant gets a chance to defend the charge with receipts or proof of delivery, and your bank decides who keeps the money.
- Chargebacks take time — expect two to three weeks for a temporary refund, and up to 90 days for a final decision.
- Too many chargebacks can cause a merchant to lose their ability to accept cards, but this does not affect your account.
When you can file a chargeback
You can file a chargeback for several reasons. The most common is an unauthorized charge — someone used your card number without permission. You can also file if you were charged twice for the same thing, if a charge appeared for an amount different from what you agreed to, or if you ordered something and it never arrived.
A chargeback is also an option when a merchant refuses to refund you for a legitimate problem. If you returned an item and the store won't process the refund, or if you paid for a service that was never delivered, you can dispute the charge through your bank instead of fighting with the merchant directly.
What you cannot use a chargeback for is a change of mind. If you bought something, received it in good condition, and straightforward decided you didn't want it, that is a return or refund issue — not a chargeback matter. Your bank will likely deny the dispute if the merchant can show proof that you received what you ordered.
How to file a chargeback with your bank
Start by contacting your bank directly. Call the number on the back of your card or log into your online banking account and look for a "dispute" or "report fraud" option. You will need to tell your bank the transaction date, the merchant name, the amount, and why you are disputing it.
Your bank will ask you questions to understand what happened. Be specific: if the item never arrived, say when you expected it and what tracking information shows. If it was unauthorized, explain why you know you didn't make the purchase. If the amount was wrong, describe what you agreed to pay. Write down the date and time you called, and ask for a reference number.
Your bank will then file the chargeback with the merchant's bank. This triggers what is called the chargeback process — a formal dispute between the two banks. You do not need to do anything else at this point, though your bank may ask you to send written documentation (like emails with the merchant or photos of a damaged item) within a set timeframe.
What happens after you file
Your bank usually issues a temporary refund within two to three weeks. This money goes back into your account while the dispute is being investigated. However, this is not final — the merchant has the right to fight back.
The merchant's bank will contact them and ask for evidence. The merchant can submit a receipt showing you authorized the charge, tracking information proving the item was delivered, or a signed contract showing you agreed to the terms. If the merchant provides strong evidence, your bank may reverse the temporary refund and you will owe the money again.
The final decision usually comes within 60 to 90 days. Your bank will notify you of the outcome. If your bank wins the dispute, the refund becomes permanent. If the merchant wins, the charge goes back on your account and you may owe the money.
The difference between a chargeback and a refund
A refund is money the merchant gives you directly. You contact the store, explain the problem, and they process the refund themselves. This is faster and simpler — the money can appear in your account within days.
A chargeback is what you do when the merchant will not refund you or will not respond. It is more formal, takes longer, and involves your bank forcing the issue. Merchants dislike chargebacks because they cost them money in fees and can damage their reputation with the card networks.
Always try to get a refund from the merchant first. If they refuse, ignore your requests, or go out of business, then file a chargeback. Your bank prefers this order too — they would rather see merchants and customers work things out directly.
What happens to the merchant
When a chargeback is filed against them, the merchant's bank charges them a fee — usually between $15 and $100 per chargeback. The merchant also loses the sale and the product (if they shipped it). If they lose the chargeback dispute, they have to refund the full amount on top of the fee.
Merchants track their chargeback rate. If too many customers dispute charges, the card networks may fine the merchant or revoke their ability to accept cards altogether. This is a serious business consequence, which is why merchants take chargebacks seriously and often fight them with documentation.
None of this affects you. Filing a chargeback does not damage your credit score or your relationship with your bank. Your bank's job is to protect you, and chargebacks are a tool they use to do that.
How long a chargeback takes
The timeline varies depending on your bank and the card network, but here is what typically happens:
- Day 1: You report the dispute to your bank.
- Days 2–5: Your bank investigates and may ask you for more information.
- Days 5–21: Your bank issues a temporary refund while the chargeback is processed.
- Days 21–60: The merchant's bank contacts them, the merchant responds with evidence, and the networks review the case.
- Days 60–90: Your bank makes a final decision and notifies you.
Some banks move faster, and some merchants respond slowly. If the merchant does not respond within their important date, your bank may rule in your favor by default. If the merchant provides strong evidence quickly, the decision may come sooner.
Frequently Asked Questions
Can I file a chargeback if I already got a refund from the merchant?
No. Once the merchant refunds you, there is nothing to dispute. If the refund was promised but never arrived, contact the merchant to track it down. If they refuse to refund you after promising to, then you can file a chargeback.
What if the merchant claims I authorized the charge?
If you truly did not authorize it, your bank will side with you. The merchant needs proof — a signed receipt, an email where you approved it, or a delivery confirmation. If you did authorize it but the merchant failed to deliver or sent the wrong item, that is a different dispute (non-delivery or item not as described), and your bank can still help.
Will filing a chargeback hurt my credit score?
No. Chargebacks do not appear on your credit report and do not affect your credit score. Your bank uses chargebacks as a consumer protection tool, and using it does not count against you.
Can a merchant sue me over a chargeback?
Rarely. A merchant can pursue you in small claims court if they believe the chargeback was fraudulent, but this is uncommon and expensive for them. Most merchants accept the chargeback and move on, especially if your bank's decision was final.
What if my bank denies my chargeback?
If your bank rules against you, the charge stays on your account. You can ask your bank to explain their decision and review the evidence they received. Some banks allow you to appeal, but the outcome is usually the same if the merchant provided strong proof of the transaction.
