# What Is A Chargeback: A Merchant’s Guide

A chargeback is a forced reversal of a card payment initiated through the cardholder’s issuing bank. It returns the disputed amount to the cardholder and debits the merchant, although the merchant may challenge the dispute by submitting evidence. The chargeback process is governed primarily by card networks such as Visa and Mastercard, along with applicable laws, regulations, and acquiring-bank procedures.

Mastercard’s research with Datos Insights projects chargebacks to grow 37 per cent between 2025 and 2029, representing around [46.1](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html) billion USD in disputed transactions in 2029.

For online merchants, chargebacks not only create a direct financial loss, but can also increase operational costs, affect payment processing arrangements, and expose businesses to card-network monitoring programmes. Merchants with high dispute ratios may face additional requirements, financial penalties, or restrictions on their ability to accept card payments.

## Key takeaways

- A dispute is the cardholder’s claim that a transaction is invalid or should be reversed. A chargeback is the formal reversal initiated through the issuing bank.
- Five parties are involved in the chargeback process: the cardholder, issuing bank, card network, acquiring bank or payment provider, and merchant.
- Cardholders generally have up to 120 days to raise a dispute, while merchants often have around 30 to 45 days to respond. The deadline may vary based on the reason code, network, and stage of the process.
- Visa’s merchant Excessive threshold reportedly fell from 2.2 per cent to 1.5 per cent on 1 April 2026 in most regions, with a minimum of 1,500 dispute events per month.
- On average, merchants pay approximately 128 USD per chargeback. This can include the disputed amount, fees, operational time and lost goods or services.
- Where liability shift applies, 3D Secure can transfer liability for eligible unauthorised-card fraud disputes. However, it doesn’t generally protect merchants against service-related disputes, such as non-delivery or goods not as described.

## What is a chargeback?

A chargeback is a consumer-protection mechanism governed by card-scheme rules and, in some markets, supported by statutory consumer rights.

When a cardholder reports to their issuing bank that a card transaction is incorrect or should be reversed, the bank can initiate a dispute through the card network. The disputed funds may be debited from the merchant’s acquiring bank and temporarily withheld or recovered from the merchant before the dispute has been resolved. The merchant can usually challenge the chargeback by submitting evidence.

### Chargeback vs dispute

A dispute is a cardholder’s claim that a transaction is incorrect or should be reversed. A chargeback is the formal reversal of funds initiated through the issuing bank as part of the dispute process.

The terminology varies between card networks. Visa uses the term dispute for the wider process in its [Visa Core Rules](https://usa.visa.com/dam/VCOM/download/about-visa/visa-rules-public.pdf). Its rules refer to dispute conditions, acquirer responses, and subsequent pre-arbitration and arbitration stages. In contrast, Mastercard continues to use chargeback for the formal dispute procedure and second presentment for the merchant-side response.

### Chargeback vs refund vs reversal

A refund is a payment reversal initiated voluntarily by the merchant, usually to return all or part of the purchase amount to the customer. A chargeback, by contrast, is initiated through the cardholder’s issuing bank and handled under the applicable card-network rules.

Chargebacks can trigger dispute fees and contribute to a merchant’s card-network monitoring ratios, whereas ordinary merchant-initiated refunds generally don’t count towards those ratios.

## How does a chargeback work?

A chargeback follows a sequence involving the cardholder, issuing bank, card network, acquiring bank or payment provider, and merchant.

**Step 1:** A cardholder contacts their issuing bank to report a problem with a transaction.

**Step 2:** The issuer assesses the claim against the applicable card-network rules and identifies the relevant dispute reason or condition.

**Step 3:** If the claim qualifies, the issuer initiates a chargeback through the card network.

**Step 4:** The network routes it to the merchant’s acquirer or payment provider, which notifies the merchant and processes the associated debit under its arrangements.

**Step 5:** The merchant either accepts the chargeback or challenges it by submitting evidence (representment).

**Step 6:** The issuer reviews the merchant’s response. If the dispute remains unresolved, it may progress to further stages, such as pre-arbitration and arbitration, depending on the network’s rules. At arbitration, the card network makes a decision under its applicable procedures.

### Parties involved in a chargeback

## What are the common reasons for chargebacks?

Common chargeback triggers include purchase confusion, billing errors, and fraud. Mastercard’s research with Datos Insights found that fraud, both third-party and first-party, accounts for around [45](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html) per cent of merchant chargeback volume globally.

Many [chargebacks can be prevented](https://www.unlimit.com/blog/payments/what-are-payment-reversals-and-8-easy-ways-to-prevent-them/) because they arise when customers don’t recognise a legitimate payment. Mastercard reports that [48](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html) per cent of consumers have mistakenly disputed a legitimate charge because of unclear billing descriptors, forgotten subscription renewals, and purchases made through third-party platforms.

Other common causes include:

- **Non-delivery:** Goods or services weren’t provided to the customer.
- **Product or service not as described:** The product or service is different from what was advertised or agreed.
- **Duplicate or incorrect charges:** The customer is billed more than once or for an incorrect amount.

These problems can be particularly relevant to card-not-present transactions. According to Mastercard’s research, card-not-present transactions accounted for [63](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html) per cent of merchants’ transactions in its dataset.

### What is friendly fraud (first-party misuse)?

Friendly fraud, also referred to as first-party misuse, occurs when a cardholder disputes a transaction that they or someone authorised to use their card made. The customer may claim not to recognise the payment, deny making the purchase, or argue that the transaction should be reversed despite having received the goods or services.

Visa identifies several common forms of friendly fraud, including household members using a saved card, confusion over billing descriptors, attempts to keep goods without paying, and misuse of return policies.

According to Visa, friendly fraud accounts for around [20](https://corporate.visa.com/en/solutions/visa-protect/insights/friendly-fraud.html) per cent of fraudulent disputes globally and can reach 30 per cent for high-volume online merchants.

## Chargeback reason codes

A [reason code](https://beastinsights.com/chargeback-reason-codes#visa) is the issuer’s label for why the chargeback was raised, and it decides what evidence can overturn it. Visa groups its dispute conditions into four families: 10.x for fraud, 11.x for authorisation, 12.x for processing errors and 13.x for consumer disputes. Mastercard uses four-digit message reason codes beginning with 48.

## Chargeback time limits (2026)

Cardholders generally have up to [120](https://www.investopedia.com/terms/c/chargeback-period.asp) days to dispute a transaction. For certain disputes involving goods or services that were not received, the period may be calculated from the expected delivery or service date rather than the original transaction date.

Merchants have considerably less time to respond. Once an acquirer or payment provider notifies the merchant of a chargeback, it sets a response deadline based on the applicable network rules and its own processing requirements. Its internal deadline may be earlier than the network’s final deadline.

## How much do chargebacks cost?

Chargebacks cost more than the disputed transaction amount. Merchants may lose the sale, the goods or services provided, shipping costs, and the chargeback fee.

If chargeback levels rise, the business may face additional acquiring costs, monitoring programme fees, or restrictions on its ability to accept card payments. As a result, even a low-value chargeback can create a net loss, including when the merchant successfully challenges the dispute.

### Direct costs

- **The disputed transaction:** The merchant may lose the payment if the chargeback is upheld.
- **Goods or services provided:** The merchant may have delivered the product or completed the service without receiving payment.
- **Shipping and fulfilment:** Delivery, packaging, and fulfilment expenses may not be recoverable.
- **Chargeback fees:** The acquirer or payment provider may charge a fee for processing the dispute.

Research by Mastercard and Javelin estimates that third-party services cost merchants an average of [46](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html) USD per chargeback.

### Operational and ratio costs

Handling a chargeback also consumes internal resources. Employees may need to investigate the transaction, retrieve order and delivery records, communicate with the payment provider, prepare evidence, and monitor the outcome.

Mastercard and Javelin estimate that US merchants incur an average of [128](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html) USD in internal and third-party costs per chargeback, excluding the value of lost goods or services. This comprises approximately 82 USD in internal costs and 46 USD in third-party fees. For merchants with annual revenue of 1 billion USD or more, reported internal costs average 151.88 USD per chargeback.

According to [Mastercard’s research with Datos Insights](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/what-s-the-true-cost-of-a-chargeback-in-2025.html), the average value of a disputed transaction varies by industry.

Average disputed transaction values also vary by country:

## Chargeback ratio and card-scheme monitoring programs (2026)

Card networks use chargeback ratio, alongside fraud data, to identify merchants and acquirers that may require additional monitoring.

The basic formula for calculating the chargeback ratio is to divide chargebacks by the number of transactions in a calendar month and multiply by 100. For instance, 15 chargebacks on 1000 transactions brings the chargeback ratio to 1.5%.

Mastercard calculates a merchant’s chargeback ratio by dividing the number of chargebacks in a month by the number of transactions in the previous month.

In contrast, Visa’s Visa Acquirer Monitoring Program (VAMP) ratio divides the number of fraud reports plus disputes by the number of settled transactions.

## Can merchants dispute a chargeback?

Merchants can challenge a chargeback through representment, a formal process in which the merchant submits evidence to its acquirer, which forwards the response to the issuer through the card network.

For a representment to be worthwhile, the merchant should assess whether the available evidence addresses the specific dispute reason and whether the potential recovery justifies the fees and operational effort. The issuer evaluates the evidence under the applicable network rules, so a strong submission can improve the merchant’s position but doesn’t guarantee a successful outcome.

### Visa Compelling Evidence 3.0.

Visa’s Compelling Evidence 3.0 (CE 3.0) framework applies to Visa dispute reason 10.4, Other Fraud: Card-Absent Environment. It allows qualifying merchants to use a cardholder’s earlier undisputed transaction history to challenge a claim that a card-not-present purchase was unauthorised.

The framework generally requires two earlier transactions made more than 120 days and no more than 365 days before the disputed transaction’s processing date. Neither earlier transaction must have been reported as fraud. The merchant must also provide matching data elements linking the earlier purchases to the disputed transaction. These include a device identifier or fingerprint, or an IP address, together with at least one other qualifying element, such as a login ID or delivery address.

### Mastercard First-Party Trust

Mastercard’s [First-Party Trust](https://www.mastercard.com/global/en/business/cybersecurity-fraud-prevention/identity/first-party-trust.html) programme enables merchants to share enhanced transaction information with issuers, either during authorisation or as part of the dispute process. The information can include device, delivery and identity data. Mastercard uses these insights and its network-level risk models to help issuers distinguish genuine third-party fraud from first-party misuse. Its programme also includes rules defining evidence that can qualify merchants for chargeback protection.

### How often do merchants win?

[Mastercard’s 2025 State of Chargebacks](https://www.mastercard.com/global/en/news-and-trends/Insights/2025/2025-global-chargebacks-outlook.html) research, conducted with Datos Insights, found that merchants who represented chargebacks won about half of the cases they contested on average across the United States, United Kingdom, Australia, and Brazil.

### When should a merchant accept a chargeback?

A merchant should consider accepting a chargeback when the evidence is insufficient, the case is unlikely to succeed, or the cost of contesting it exceeds the amount that could reasonably be recovered.

The calculation should also account for representment fees, internal staff time, third-party dispute-management costs and any further costs associated with escalation. A low-value transaction with little supporting evidence may not justify a lengthy response process.

## How to prevent chargebacks?

### \#1 Use 3D Secure for liability shift

3D Secure (3DS) is the cardholder authentication protocol behind Visa Secure and Mastercard Identity Check. It shifts liability for certain unauthorised transaction disputes from the merchant to the issuer. However, this shift is subject to card-scheme rules, transaction types, authentication results, and applicable exemptions.

The liability shift generally covers fraud-related disputes, and doesn’t protect against claims involving non-delivery, defective or misrepresented goods, or cancelled subscriptions. It is also separate from Visa’s Compelling Evidence 3.0 framework, which allows merchants to use qualifying previous transaction data to challenge certain card-absent fraud disputes.

### \#2 Make the charge recognisable

Customers may dispute legitimate transactions when they don’t recognise the information appearing on their card statements. This is particularly common when the billing descriptor differs from the brand name displayed during checkout.

Merchants should use recognisable business or trading names across card statement descriptors, order confirmations, receipts and subscription renewal reminders. Including a website address or customer-support contact details can also help customers identify purchases and resolve questions directly.

### \#3 Keep policies and proof visible

Customers are less likely to misunderstand a purchase when its terms are clear before payment. Merchants should display return and refund policies, cancellation terms, subscription prices, renewal dates, delivery costs, and estimated delivery times at checkout.

They should also retain evidence that customers accepted the relevant terms. This may include order confirmations, proof of delivery, sign-up consent, cancellation records, login history and usage data for digital products and subscriptions.

### \#4 Resolve early with pre-dispute tools

Pre-dispute services help merchants identify and address potential disputes before they become formal chargebacks. However, the tools perform different functions:

- Visa Order Insight provides issuers and cardholders with enhanced transaction and order information to help identify purchases
- Visa Resolve supports resolving eligible disputes before they progress to formal chargebacks
- Mastercard Ethoca Alerts notifies participating merchants of potential disputes, allowing them to resolve the issue, often through a refund
- Mastercard Consumer Clarity provides enhanced transaction information to help cardholders recognise purchases.

### \#5 Give customers a faster route to resolution

Customers who cannot reach a merchant, obtain a refund, or cancel a subscription may turn to their bank instead. Merchants should provide accessible support channels, respond promptly to complaints and make subscription cancellation straightforward.

## Chargebacks for cross-border merchants

Selling into a new market introduces differences in currency, billing descriptors, language, delivery practices, and consumer-protection laws. These differences can make transactions harder for customers to recognise, and for merchants to defend when a dispute arises.

For merchants entering new markets, offering a mix of local payment methods can make checkout more relevant to customers’ preferences. Providing [bank transfers](https://www.unlimit.com/blog/payments/how-do-bank-transfers-work-what-should-businesses-know/) and [digital wallets](https://www.unlimit.com/blog/payments/digital-wallet-payments-a-practical-guide-for-global-businesses/) alongside cards gives customers more ways to pay and allows merchants to adapt their payment mix market by market.

Unlimit is a global financial infrastructure provider that offers access to more than 1,000 [payment methods](http://unlimit.com/payment-methods/) through a single integration, helping businesses support different payment preferences across markets.

## FAQ

**What does a chargeback reversal mean?**A chargeback reversal usually means that a merchant has successfully challenged a chargeback and the disputed funds have been returned to them. The term can also be used loosely to describe the original reversal of a card payment. Its meaning depends on the context.

**Is a chargeback a refund?**A chargeback is not the same as a refund. A refund is issued directly by the merchant to return money to a customer, while a chargeback is initiated by the customer through their bank or card issuer to dispute a transaction. The bank then reviews the claim and may reverse the payment, withdrawing the funds from the merchant’s account.

**What is the difference between a dispute and a chargeback?**A dispute is the cardholder’s claim that a transaction is incorrect or should be reversed. A chargeback is the formal reversal of funds initiated through the issuing bank as part of the dispute process. Visa uses the term dispute for the wider process, so the two terms may appear interchangeably in card-network documentation.

**How long does a chargeback take?**There is no fixed timeframe for resolving every chargeback. The duration depends on the reason for the dispute, the card network and whether the case progresses beyond the initial response stage. Cardholders commonly have up to 120 days to raise a dispute, while merchants usually have a shorter response window of around 30 to 45 days.

**Who pays for a chargeback?**The merchant generally bears the financial impact if a chargeback is upheld. This can include the disputed transaction amount, chargeback fees, the cost of goods or services already delivered, and internal dispute-handling costs. The issuing bank and acquiring bank also incur their own processing expenses.

**What is a good chargeback ratio?**There is no single ideal chargeback ratio that applies to every merchant. The objective is to remain below the monitoring thresholds relevant to the card network, region, and merchant category.
Visa’s 2026 merchant monitoring criteria include a 1.5% threshold for its Excessive category in most regions, subject to additional event-count requirements. Mastercard’s Excessive Chargeback Merchant (ECM) programme also uses a 1.5% ratio threshold alongside a minimum chargeback count.

**Can a merchant dispute a chargeback?**A merchant can challenge a chargeback by submitting evidence through a process known as representment. Relevant evidence may include order confirmations, delivery records, customer communications, refund records, authentication information, and proof that the agreed service was provided.

**Does 3D Secure protect against chargebacks?**3D Secure can help protect merchants against certain fraud-related chargebacks by shifting liability to the issuer, provided the transaction meets the applicable authentication and liability-shift requirements.
