Completion percentage is a key statistic in football that measures a quarterback's accuracy by calculating the ratio of completed passes to total pass attempts, expressed as a percentage.
The calculator uses the completion percentage formula:
Where:
Explanation: The formula calculates the percentage of passes that were successfully completed by dividing completions by attempts and multiplying by 100.
Details: Completion percentage is a critical metric for evaluating quarterback performance, offensive efficiency, and overall team passing game effectiveness in football.
Tips: Enter the number of completions and total attempts. Both values must be valid (completions cannot exceed attempts, attempts must be greater than 0).
Q1: What is considered a good completion percentage?
A: In professional football, a completion percentage above 60% is generally considered good, while elite quarterbacks often achieve 65% or higher.
Q2: Does completion percentage account for dropped passes?
A: No, completion percentage only measures completed passes versus attempts, regardless of whether incomplete passes were the quarterback's fault or due to receiver errors.
Q3: How does completion percentage differ from passer rating?
A: Completion percentage is a single metric focusing on accuracy, while passer rating incorporates multiple factors including yards per attempt, touchdowns, and interceptions.
Q4: Can completion percentage be over 100%?
A: No, completion percentage cannot exceed 100% as completions cannot exceed attempts in valid statistical recording.
Q5: How has the average completion percentage changed over time?
A: Average completion percentages have increased over the decades due to rule changes favoring passing offenses and offensive scheme evolution.
