What is authorization rate? (approval rate explained)

Authorization rate measures how often payment attempts succeed. When you charge a customer's card, the issuing bank either approves or declines the transaction. Authorization rate is the percentage that get approved: approved transactions divided by total attempts, multiplied by 100.

For a subscription business running 10,000 renewal charges per month, a 90% authorization rate means 9,000 successful payments and 1,000 declines. That gap — the 10% that failed — is where revenue leaks out. Some of those declines are recoverable; others are not. The authorization rate tells you the size of the problem.

Authorization rate is not a fixed number you control directly. It is the result of many factors interacting at the moment of charge:

• Card type and issuer — debit cards, prepaid cards, and cards from smaller issuers tend to decline more often than major credit cards.
• Geography — cross-border transactions face higher decline rates due to fraud scrutiny and currency conversion friction.
• Merchant category code (MCC) — some industries face elevated scrutiny from issuers and card networks.
• Transaction amount — unusually high charges relative to the cardholder's history trigger fraud flags.
• Time since last successful charge — stale card credentials and expired cards accumulate between billing cycles.
• Fraud filter sensitivity — overly aggressive fraud rules decline legitimate transactions (false positives).

Improving authorization rate is not about re-running the same declined charge. It requires addressing why the decline happened in the first place.

Account updater services keep card credentials current when issuers reissue cards. Smart retry logic times re-attempts for soft declines when the issuer is more likely to approve. Customer outreach collects updated payment methods when the card itself is the problem.

Revatto handles the recoverable declines for you: AI detects the decline type, times retries for soft declines, and runs email, SMS, and human outreach for hard declines that need a new card. You only pay when the payment is recovered — 20% of the first recovered payment, $0 monthly.
