What Is a Chargeback? How It Works and What It Costs

Who this helps: you run a subscription business, a chargeback notice just arrived, and you want to know what happens next and what it will cost you.

Most payments are finished the day they happen. A chargeback reopens one, sometimes months later, and not at your request. The customer's bank takes the money back, charges you a fee, and adds a mark to your chargeback record, the number that decides whether you keep your merchant account. Here is how that works, in plain terms.

What is a chargeback?

A chargeback is a card payment reversed by the customer's bank instead of by you. The customer tells their bank a charge is wrong, and the bank takes the money back out of your account, usually with a fee.

The simplest way to hold the difference: a refund is you returning the money, and a chargeback is the customer's bank taking it back. Our chargeback vs refund guide covers why that difference matters so much.

Four parties are involved, and only one of them is you. There is the customer, and the customer's bank, which issued their card. There is the card network, such as Visa or Mastercard, which writes the rules. And there is your side of the payment: you, plus the processor or bank that collects card payments for you.

Chargebacks started as consumer protection: the US Fair Credit Billing Act of 1974 gave credit card holders the right to dispute charges they did not authorize or goods they never received. Card network rules now go further, covering debit cards too and typically giving customers up to 120 days after a payment. And they are common: Mastercard and Datos Insights project 286 million chargebacks worldwide in 2026.

How does a chargeback work, step by step?

In five steps over two to three months, and the money leaves your account at the first one. Take Maya, who pays $29 a month for a fitness app. Her statement shows a line she does not recognize, so she opens her banking app and taps "dispute." Here is what happens next.

1. Maya's bank files the chargeback. It attaches a reason code, a short label for the complaint, such as fraud or a canceled subscription. Our reason code guide explains each one, and American Express uses its own codes.
2. The money leaves your account right away. The card network pulls the $29 back through your processor, and a fee comes out of your balance with it: $15 at Stripe, and $35 is a common figure at mid-market and high-risk processors.
3. You get a notice and a deadline. You can accept the chargeback, or fight it with evidence, such as proof that Maya agreed to the billing terms and used the app. At Stripe, you usually have 7 to 21 days.
4. Maya's bank reviews your evidence. Stripe says banks usually take 60 to 75 days to decide.
5. The bank decides. If you win, the $29 comes back to you. If you lose, it stays with Maya. At Stripe that decision is final, and some other processors allow an appeal to the card network.

What are the three types of chargebacks?

Real fraud, friendly fraud and merchant error, and only one of them involves a thief.

1. Real fraud. Someone used a stolen card, and the cardholder never made the purchase.
2. Friendly fraud, or plain confusion. The cardholder did make the purchase but disputes it anyway. They did not recognize the name on their statement, forgot that a free trial turns into a paid plan, or a family member used the card. Some do it knowingly, and many do not: Mastercard's 2026 research found that 48% of consumers have disputed a legitimate charge by mistake.
3. Merchant error. Something went wrong on your side: the customer canceled and was still charged, was charged twice, or never got access to what they paid for.

Mastercard's data puts fraud, meaning stolen cards plus customers who knowingly dispute a real purchase, at around 45% of merchant chargebacks worldwide. Mastercard also notes that subscription businesses get a high volume of chargebacks from customers who struggle to manage their recurring payments, which is why the middle type deserves most of your attention.

What does a chargeback cost you?

More than the sale. Mastercard's research puts the average cost at $128 per chargeback on top of the disputed amount: about $82 in your own costs, such as the time your team spends on each case, and about $46 in fees paid to outside companies. Mastercard notes that together, these costs often exceed the value of what was disputed.

Run Maya's chargeback through those averages and a $29 charge costs about $157 if you lose it, more than five times the sale. Your own figure depends on your fee and how long each case takes your team, and the chargeback cost calculator works it out from your numbers. Then there is the cost no invoice shows, which the next section is about.

What happens if you win or lose a chargeback?

If you win, you get the money back, but the chargeback still counts against you. Each path ends differently:

• You accept it. You lose the sale and the fee, and the case closes.
• You fight and lose. You lose the sale and the fee, plus any fee your processor charges for fighting.
• You fight and win. The sale comes back, but the filing fee usually stays with your processor, and the mark on your record stays too.

At Stripe, fighting costs a second $15, which comes back only if you win. Mastercard says the rest directly: "Even when the merchant 'wins' a chargeback, the customer's dispute still impacts their chargeback ratio." So fighting is a money decision, not a record decision. Whether a case is worth fighting depends on the sale, your evidence and your costs, which our refund, fight, or keep guide works through.

Why do chargebacks hit subscription businesses hardest?

Because the charges are small, they repeat, and the ratio that decides your account counts every one. Mastercard's 2025 data puts the average subscription chargeback at $69, the lowest of any industry it measured, while the fee and the handling time stay the same. So each chargeback costs you more, relative to what you earned from it.

They also arrive in groups. A customer who does not recognize one renewal may dispute several at once, and Stripe notes that a bank can combine them into one larger dispute. Mastercard adds a cost that is easy to miss: an accidental chargeback can trigger fraud blocks that keep the customer from subscribing again.

Then there is the ratio. Your chargeback ratio is your chargebacks in a month divided by your sales. The Visa Acquirer Monitoring Program (VAMP), Visa's monitoring program, flags a merchant when its fraud reports and disputes together reach 1.5% of its online sales, once the count reaches 1,500 in a month. That line has applied in the US, Canada, Europe and Asia Pacific since April 1, 2026. Mastercard's program flags a merchant at 100 chargebacks and a 1.5% ratio in the same month. Both count chargebacks, not dollars, so a $9 dispute weighs exactly as much as a $900 one. Staying over these lines brings fines and, at worst, the loss of the account you use to take payments.

How do you stop chargebacks before they happen?

Mostly by giving customers no reason to call their bank. Four habits do most of the work:

1. Make every charge recognizable. Put your brand in the statement descriptor, the name customers see on their card statement.
2. Make canceling easy, and remind before you bill. A clear cancel button and an email before each renewal or trial conversion remove the most common reasons for friendly fraud. The prevention playbook covers both in order of impact.
3. Catch the ones that still get filed. Chargeback alerts give you a short window to refund a dispute before it becomes a chargeback, and a dispute refunded that way never becomes one.
4. Watch your ratio every month. Check it against Visa's and Mastercard's lines with the VAMP calculator, not when a warning letter arrives.
