Approval Rate
What Is Approval Rate? Definition and How It Works
Definition
Approval rate in payments is the percentage of total payment attempts that result in a completed, successful transaction, including transactions recovered through retry, failover, or alternative payment methods after an initial decline.
How it works
Approval rate is a broader measure than authorisation rate. Authorisation rate measures first-attempt approval; approval rate captures the full outcome of a payment attempt including any recovery steps applied after an initial decline. A payment attempt that is declined on first authorisation but recovered through retry or failover and ultimately completes successfully contributes to approval rate but reduces authorisation rate on the first attempt.
The gap between authorisation rate and approval rate quantifies the effectiveness of the merchant's recovery infrastructure. A merchant with a 92% authorisation rate and a 95% approval rate has a 3 percentage point recovery rate, those are transactions that were initially declined but recovered without the customer experiencing a failure.
Recovery mechanisms that lift approval rate above authorisation rate include: automatic failover to an alternative acquirer on technical failures, smart retry logic for soft declines within scheme-permitted windows, 3DS step-up authentication on transactions that received a soft decline with an authentication challenge instruction, and account updater services that refresh stale stored credentials before they generate a decline.
Approval rate is the most customer-visible payment metric: from the customer's perspective, a payment attempt either works or it does not. They do not know whether the successful outcome came on the first attempt or after a transparent recovery. Optimising approval rate directly reduces customer-facing payment failures.
Why it matters
Approval rate gap analysis reveals recovery infrastructure quality: a large gap between authorisation rate and approval rate (5+ points) suggests effective retry, failover, and recovery logic. A small gap (under 1 point) suggests limited recovery capability and potential to invest in retry and failover infrastructure.
Approval rate benchmarks should account for recovery mechanisms: comparing approval rates across providers requires understanding whether recovery mechanisms (retry, failover) are included in the metric. Providers who report only first-attempt authorisation rates as approval rates overstate the gap relative to providers reporting true end-to-end approval rates.
Customer payment failure rate is the business impact metric: approval rate inverted (1 minus the approval rate) is the rate at which customers experience payment failures. For subscription businesses, this equals involuntary churn from payment failures. For e-commerce, it is checkout abandonment from failed payments. These downstream impacts make approval rate a board-level metric.
Approval rate by customer segment reveals where recovery infrastructure should focus: new customers (no prior relationship, no stored credentials) have inherently lower first-attempt authorisation rates. Returning customers with stored credentials and account history should have higher rates. Segment-level approval rate data guides where to invest.
With PXP
PXP measures and reports both first-attempt authorisation rate and end-to-end approval rate in its analytics dashboard. Recovery mechanisms including smart routing, failover, and soft decline retry are built into PXP's platform, with their contribution to approval rate surfaced in performance reporting.
Frequently asked questions
What is the difference between approval rate and authorisation rate?
Authorisation rate measures what percentage of authorisation requests are approved on the first attempt. Approval rate measures the percentage of total payment attempts that result in a successful transaction, including any recoveries through retry, failover, or step-up authentication. Approval rate is always greater than or equal to authorisation rate. The difference between the two is the recovery rate, transactions saved by post-decline recovery mechanisms.
How is the gap between authorisation rate and approval rate measured?
The gap is (approval rate minus authorisation rate). If authorisation rate is 91% and approval rate is 94%, the recovery rate is 3 percentage points. This represents transactions that were initially declined but subsequently recovered. To measure this accurately, the payment system must track each unique payment attempt as a single unit (not each authorisation attempt separately) and record whether it ultimately succeeded.
What does a high approval rate gap indicate about a merchant's payment stack?
A material gap between authorisation rate and approval rate (3+ percentage points) indicates effective recovery infrastructure: good retry logic for soft declines, failover routing for technical failures, and potentially 3DS step-up flows for challenge-required declines. A near-zero gap suggests limited recovery capability; each initial decline is a final decline, and is an indicator that retry, failover, and recovery mechanisms should be evaluated.
How does approval rate differ for new versus returning customers?
Returning customers with stored credentials and a purchase history typically have higher approval rates than new customers because: stored credentials are pre-verified; the issuer recognises the merchant from prior successful transactions; and account updater services keep stored card data current. New customers lack this history, have higher first-attempt decline rates from issuer conservatism on unfamiliar cardholders, and have no stored credentials to optimise. Segment-level approval rates should be tracked separately.
