How to Lower Your Chargeback Ratio: A Step-by-Step Guide

Your chargeback ratio is the number your processor watches most closely. Let it creep too high and you can face monitoring fees, a reserve, or a closed account. The good news: most chargebacks come from a handful of fixable causes. This guide shows how to find yours and bring the ratio down.

How your chargeback ratio is measured

At its simplest, the ratio is chargebacks divided by transactions for a period, shown as a percentage. In practice, each card network counts a little differently:

• Visa uses a combined ratio under its Visa Acquirer Monitoring Program (VAMP): fraud reports plus disputes, divided by settled card-not-present transactions.
• Mastercard compares a month's chargebacks with the previous month's transactions.

Use our chargeback ratio calculator to see where you stand and how many disputes you can have at your volume before you hit a threshold.

The thresholds to stay under

These are network limits, not safe targets. Your acquirer can set stricter internal limits, and Visa applies lower triggers to merchants whose acquirer is itself over its limits. Ask your processor which numbers apply to your account, and aim to stay well below them.

Step 1: Find out why customers dispute

Every chargeback comes with a reason code. Pull the last three to six months of disputes and group them by reason. Most fall into four buckets:

• True fraud: a stolen card was used on your site.
• "I don't recognize this": the customer doesn't connect the charge on their statement to your business.
• Subscription and cancellation issues: the customer forgot they signed up, or tried to cancel and was charged anyway.
• Product or service problems: the order arrived late, broken, or not as described.

Not sure what a code means? Look it up in our chargeback reason code lookup. Fix the biggest bucket first.

Step 2: Fix the cause, bucket by bucket

Stop fraud at checkout

• Turn on address verification (AVS) and security code (CVV) checks.
• Use 3-D Secure on higher-risk orders. When an authentication succeeds, liability for many fraud disputes can shift to the card issuer.
• Set velocity limits, for example on the number of cards tried from one device or IP address.
• Review large first orders, mismatched billing and shipping countries, and rush shipping before you fulfil them.

Make your charge easy to recognize

• Use a billing descriptor that matches your brand name, not a legal entity customers have never heard of.
• Add your website or a support phone number to the descriptor if your processor allows it.
• Send a receipt email for every charge that uses the same name.

Clean up subscriptions and trials

• Show the price, billing frequency and how to cancel before checkout.
• Send reminders before a free trial converts and before annual renewals.
• Make cancelling as easy as signing up, and stop billing immediately when a customer cancels.
• Don't keep retrying a declined card indefinitely.

Deliver what you promised

• Describe products accurately, with realistic delivery times.
• Ship with tracking and send shipping updates.
• Answer support requests quickly. A customer who gets a reply rarely calls their bank.
• Refund obvious problems before the customer disputes. A refund costs you the sale; a chargeback costs the sale, a fee and counts against your ratio.

Step 3: Catch disputes before they become chargebacks

Pre-dispute alert services, such as Visa's Verifi tools and Mastercard's Ethoca alerts, notify you when a customer has started a dispute with their bank. If you refund in time, the case can be closed before it becomes a chargeback. Visa excludes disputes resolved through qualifying pre-dispute solutions from the VAMP ratio, subject to data timing. Exactly how each tool is counted can differ, so confirm with your processor before relying on one.

Step 4: Fight the disputes you can win

Responding with strong evidence won't always remove a dispute from your ratio, but it recovers revenue and discourages repeat "friendly fraud". For Visa card-not-present fraud disputes (reason code 10.4), Compelling Evidence 3.0 lets you show that the same cardholder made at least two earlier, undisputed purchases 120 to 365 days before the dispute, with at least two matching details such as IP address, device ID, delivery address or account login. One of the matches must be the IP address or device ID. Fraud reports that qualify for Compelling Evidence 3.0 are also excluded from the VAMP ratio, subject to timing. Keep these records for every order so you can use them.

Step 5: Track it every week

Don't wait for a monthly warning letter. Track disputes, fraud reports and refunds weekly, by product and by marketing channel. A sudden rise often points to one cause, such as a new ad that over-promises, a supplier delay, or a card-testing attack.

Already over the limit?

• Talk to your processor first. A merchant who arrives with a plan is treated very differently from one who goes quiet.
• Write a short remediation plan: the causes you found, the fixes you made, and the dates.
• Expect closer terms for a while, such as a reserve or processing limits, until your numbers recover.
• Don't open accounts elsewhere to spread the volume. Splitting volume to hide a dispute problem breaks card network rules and can get your business added to the MATCH list.
