In short
The answer first
Passing accuracy is usually the percentage of attempted passes recorded as successfully completed: completed passes divided by attempted passes, multiplied by 100. The arithmetic is simple, but the event provider's definition of a pass and a completion determines which actions enter the calculation.
Key takeaways
A 90 percent completion rate does not mean nine of every ten touches were successful; it refers to recorded pass attempts.
Data providers use event definitions to decide what counts as a pass and whether it was completed.
Short safe passes and difficult line-breaking passes can have very different risk profiles.
Set pieces, crosses, clearances and deflections can be classified differently depending on the event definition.
Pass accuracy is most informative when paired with pass location, direction, difficulty and progression.
The basic calculation
If a provider records 45 completed passes from 50 attempts, the simple completion rate is 90 percent. This is a useful summary of execution within the provider's event taxonomy.
The denominator is important. An action that the provider classifies as a clearance rather than an attempted pass should not silently be treated as a failed pass in another comparison without checking the definitions.
Why event definitions matter
Professional data companies maintain consistent definitions so matches can be compared across competitions. Opta, for example, publishes an event-definition framework covering passes and many other on-ball actions.
Different sources can still show slightly different totals if their collectors or classification rules treat borderline actions differently. The percentage is only as comparable as the underlying event definitions.
Accuracy is not the same as passing value
A centre-back recycling possession five metres sideways will often be expected to complete that pass. A midfielder attempting to split two defensive lines is taking more risk. Treating both actions as equal successes or failures can hide the reason one player has a lower completion rate.
Progressive distance, line breaks, final-third entries and expected threat are examples of additional ideas analysts use to describe what a pass achieved rather than only whether it reached a team-mate.
How to compare players fairly
Compare players with similar roles, zones and passing responsibilities before drawing a conclusion from raw percentage. A goalkeeper playing long under pressure, a holding midfielder receiving centrally and a winger crossing into the box face very different completion environments.
Volume also matters. Completing 18 of 20 passes and 90 of 100 both produce 90 percent, but the players had very different involvement in possession.
