For merchants, declined credit card transactions are frustrating. This article explores the most common reasons credit cards are declined and provides estimated statistics for each, and offers actionable tips to mitigate their impact.
On average, about 5-10% of all card transactions get declined, depending on the industry and transaction type. Of the credit card declines, the table below gives an estimate for the decline reason and the percentage chance they happen.
| Reason | Estimated % of Declines |
|---|---|
| Insufficient Funds/Over Limit | 30-40% |
| Incorrect Card Information | 15-25% |
| Expired Card | 5-10% |
| Fraud/Suspicious Activity | 10-20% |
| Technical Issues | 5-10% |
| Card Not Activated | 2-5% |
| Lost/Stolen Card | 5-10% |
| Merchant Restrictions | 1-3% |
This is the most common reason credit cards are declined. When a customer doesn’t have enough available credit or funds to cover the transaction amount, the issuer rejects the charge. This situation often arises due to high credit utilization or unexpected expenses.
Example: A customer attempts to purchase a $300 item but only has $250 available on their credit card.
Solution for Merchants:
Errors in entering card details—such as the card number, expiration date, CVV, or billing address—are especially common in online transactions. These mistakes prevent payment processors from authorizing the charge.
Example: A shopper entering their address incorrectly during an online checkout process.
Solution for Merchants:
A cardholder may unknowingly attempt to use an expired card, leading to a declined transaction. While card issuers generally send replacement cards before the expiration date, delays or oversight can result in this issue.
Solution for Merchants:
Credit card issuers monitor transactions for unusual activity that may indicate fraud. Purchases made in a new location, unusually large transactions, or frequent small purchases in quick succession can all trigger a decline as part of the issuer’s security protocols.
Example: A cardholder traveling internationally tries to use their card, but the transaction is flagged as unusual.
Solution for Merchants:
Sometimes the problem isn’t with the customer’s card but with technical glitches in payment processing systems. Network downtime, server errors, or outdated software can all lead to a failed transaction.
Solution for Merchants:
New or replacement cards require activation before use. If a customer attempts to use an inactive card, the transaction will be declined.
Solution for Merchants:
If a cardholder reports their card as lost or stolen, the issuer disables it to prevent unauthorized use. Any subsequent attempts to use the card will be automatically declined.
Solution for Merchants:
Some credit cards restrict transactions with certain merchant categories. This is more common with corporate cards or prepaid cards that have usage limitations.
Solution for Merchants:
When a customer’s card is declined, handling it well can save the sale and keep the customer happy. Follow these simple steps:
Stay Calm and Discreet
Check for Simple Errors
Suggest Contacting Their Bank
Offer Alternative Payment Methods
Provide a Record of the Decline
Keep the Sale Alive
Review Your Payment System
Document the Decline
By following these steps, you can turn a declined transaction into a chance to maintain trust and complete the sale.
