Make Fraud Losses and False Declines Tangible

Many e-commerce businesses monitor fraud, but few quantify the revenue they lose through false declines. This calculator gives you a strong first estimate of both sides.

Note: This calculation uses simplified assumptions based on your inputs. It does not replace a detailed analysis, but it is useful for understanding magnitude and prioritization.

Monthly Orders

Direct Fraud Rate (% of Revenue)

Typical range for many merchants: 0.5-2%. This refers to direct losses from confirmed fraud.

Overall Decline Rate (% of Orders)

This should include all declined orders or payments, regardless of the reason.

Share of False Declines (% of Declines)

If you do not have your own data yet, start conservatively at 30-40%.

If you already have internal numbers on fraud, authorization rates, declines, or chargebacks, this estimate can be refined substantially. In an audit, we translate those figures into concrete CX, payment, and risk priorities.
