Approval Rate (Authorisation Rate)

Approval rate, also called authorisation rate, is the share of payment attempts that a card issuer approves, making it one of the most closely watched metrics for checkout and payment performance.

What Is Approval Rate?

Every payment attempt results in either an approval or a decline from the issuing bank. Approval rate is simply the percentage of attempts that are approved, and it directly reflects how much revenue a merchant is capturing versus losing to declined transactions, separate from any issue with checkout design or customer intent.

How Approval Rate Is Measured and Improved

Approval rate is typically calculated as approved transactions divided by total transaction attempts over a given period, often segmented by market, card type or acquirer to identify where declines are concentrated. Improving it usually involves a combination of better payment routing, retrying soft declines intelligently, using local acquiring where relevant, and keeping card details current with tools like account updater.

How Approval Rate Impacts Merchant Revenue

Even a small drop in approval rate can represent significant lost revenue at scale, since every declined transaction is a customer who was ready to pay but couldn't complete the purchase. Unlike cart abandonment, which is often a UX or pricing issue, approval rate declines are frequently solvable through better routing and issuer relationships, covered in how to improve card approval rates.

Approval Rate and Payment Orchestration

A payment orchestration layer can route transactions toward the acquirer more likely to secure approval, retry certain failed attempts through an alternative path, and surface decline-code data that can help identify where revenue may be being lost.

Approval Rate by Segment

A single blended approval rate figure can hide significant variation underneath it. Breaking approval rate down by market, card type, acquirer and even time of day frequently reveals that overall performance is being dragged down by one specific segment, such as a particular country or a specific issuer relationship, rather than a systemic problem. This segmentation is what turns approval rate from a lagging indicator into an actionable one, since it points directly to where a routing change, a new local acquiring relationship, or a targeted retry strategy would have the most impact, rather than applying a blanket fix across transactions that were already performing well.
