Understanding How to Calculate Fraud Rate
In the digital economy, monitoring your fraud rate is critical for maintaining merchant account health and protecting your bottom line. Fraud rate is a key performance indicator (KPI) used by payment processors like Visa, Mastercard, and Stripe to determine the risk level of a business.
The Transaction Fraud Rate Formula
The most common way to calculate fraud rate is based on the volume of transactions. This tells you what percentage of your total orders are identified as fraudulent.
The Value-Based Fraud Rate Formula
While transaction count is important for compliance, the value-based fraud rate tells you the actual financial impact on your revenue. If high-ticket items are being targeted, your value fraud rate might be significantly higher than your transaction fraud rate.
Example Calculation
Let's say your online store processed the following last month:
- Total Transactions: 5,000
- Fraudulent Transactions: 40
- Total Sales: $250,000
- Fraud Value: $3,000
Transaction Fraud Rate: (40 / 5,000) × 100 = 0.8%
Value Fraud Rate: ($3,000 / $250,000) × 100 = 1.2%
Why Monitoring Fraud Rates Matters
Exceeding specific thresholds set by card networks (usually around 1%) can lead to significant consequences:
- High-Risk Programs: Merchants may be placed in monitoring programs (like the Visa Fraud Monitoring Program).
- Increased Fees: Payment processors often charge higher per-transaction fees for high-risk accounts.
- Termination: In extreme cases, your merchant account could be terminated, preventing you from accepting credit card payments entirely.
- Revenue Loss: Beyond the lost inventory, fraud results in chargeback fees and wasted shipping costs.
