Completions vs. Attempts
Completion Percentage Tiers
| Percentage Range | Performance Tier | Common Interpretation |
|---|---|---|
| 70%+ | Elite | Exceptional accuracy, often indicative of a quarterback in complete control of a short-to-intermediate passing game. |
| 65% – 69.9% | Great | Highly accurate and efficient. This is the mark of a top-tier starting quarterback in modern football. |
| 60% – 64.9% | Good / Above Average | A solid, reliable passer who effectively moves the offense. The league average often falls in this range. |
| 55% – 59.9% | Average / Below Average | May struggle with consistency. This range can indicate a reliance on a vertical offense or general accuracy issues. |
| Below 55% | Poor | Indicates significant issues with accuracy, decision-making, or facing immense defensive pressure. Very inefficient. |
What is Pass Completion Percentage?
The Pass Completion Percentage is a fundamental and widely-cited statistic in American football used to measure the accuracy of a quarterback. It represents the ratio of passes successfully caught by a receiver to the total number of passes thrown. A high Pass Completion Percentage is a strong indicator of a quarterback’s efficiency, precision, and decision-making ability. While not the only metric for success, it provides a clear, quantitative measure of how reliably a passer connects with their targets.
This statistic is crucial for coaches, analysts, and fans to evaluate quarterback performance. It strips away many other variables and answers a simple question: when the quarterback throws the ball, does a teammate catch it? A strong Pass Completion Percentage often correlates with sustained drives, better time of possession, and ultimately, more scoring opportunities. Some common misconceptions are that a high percentage automatically means a quarterback is better; however, it doesn’t account for the difficulty of throws, such as deep passes versus short checkdowns.
Pass Completion Percentage Formula and Mathematical Explanation
The formula to find the Pass Completion Percentage is straightforward and easy to apply. It is a simple division of two numbers, converted into a percentage format for easy interpretation.
Step-by-Step Calculation:
- Identify the number of completed passes: This is the total number of throws successfully caught by an eligible receiver.
- Identify the total number of attempted passes: This includes all throws: completions, incompletions, and interceptions.
- Divide completions by attempts: This gives you a decimal ratio.
- Multiply by 100: Convert the decimal to a percentage.
The mathematical formula is: Pass Completion Percentage = (Completed Passes / Total Passes Attempted) × 100.
| Variable | Meaning | Unit | Typical Range (Single Game) |
|---|---|---|---|
| Completed Passes | A forward pass caught by an eligible receiver. | Count | 10 – 40 |
| Attempted Passes | Any forward pass thrown by a player. | Count | 20 – 60 |
| Pass Completion Percentage | The resulting percentage of completions from all attempts. | Percentage (%) | 45% – 85% |
Practical Examples (Real-World Use Cases)
Example 1: A Highly Efficient Game
Imagine a quarterback has a stellar performance. They were precise and made good decisions, leading to a high Pass Completion Percentage.
- Inputs: 28 Passes Completed, 35 Passes Attempted
- Calculation: (28 / 35) × 100 = 0.8 × 100
- Result: 80% Pass Completion Percentage. This is an elite number, indicating the quarterback was extremely accurate and efficient, likely leading to a very effective offensive performance. For context, you might explore our Quarterback Rating Calculator to see how this impacts other metrics.
Example 2: A Struggling Performance
Now consider a quarterback facing a tough defense or having an off day. Their Pass Completion Percentage will reflect this struggle.
- Inputs: 19 Passes Completed, 40 Passes Attempted
- Calculation: (19 / 40) × 100 = 0.475 × 100
- Result: 47.5% Pass Completion Percentage. This is a very low figure, suggesting the offense struggled to move the ball through the air. This could be due to inaccurate throws, dropped passes, or excellent defensive play.

Key Factors That Affect Pass Completion Percentage Results
A quarterback’s Pass Completion Percentage is not created in a vacuum. It is influenced by a multitude of factors on and off the field.
- Offensive Scheme: A West Coast offense, which relies on short, quick, horizontal passes, will naturally lead to a higher Pass Completion Percentage than a vertical, “Air Coryell” style offense that features more high-risk, high-reward deep throws.
- Receiver Skill: The quality of the receiving corps is paramount. Receivers with great hands, precise route-running, and the ability to win contested catches can significantly boost a QB’s percentage. Dropped passes are a primary killer of a high Pass Completion Percentage.
- Offensive Line Play: The amount of time a quarterback has in the pocket is critical. Constant defensive pressure forces rushed throws, poor mechanics, and bad decisions, all of which drastically lower accuracy.
- Weather Conditions: Playing in rain, heavy wind, or snow makes the ball harder to grip and throw accurately, and harder for receivers to catch. This almost always leads to a lower Pass Completion Percentage for both teams.
- Down and Distance: On 3rd and long, defenses play softer coverage to prevent a big play, often conceding short passes. This can sometimes inflate a QB’s percentage with “safe” checkdowns that don’t convert the first down. This is where looking at Yards Per Attempt Explained becomes important.
- Player’s Own Accuracy: Ultimately, the mechanical skill of the quarterback—their footwork, throwing motion, and ability to read a defense—is the most direct factor. This is a core part of evaluating Player Performance Metrics.
Frequently Asked Questions (FAQ)
Q: What is considered a good Pass Completion Percentage?
A: In the modern NFL, a percentage above 65% is considered very good, and above 70% is elite. The league average typically hovers around 62-64%. Anything below 60% is generally seen as below average or inefficient.
Q: Does Pass Completion Percentage account for dropped passes?
A: No, it does not. A dropped pass is counted as an incompletion against the quarterback, even if the throw was perfectly accurate. This is a primary criticism of the stat, as it doesn’t fully isolate the quarterback’s performance.
Q: How is this different from Passer Rating or QBR?
A: Pass Completion Percentage is one of four components used to calculate Passer Rating, alongside yards per attempt, touchdown percentage, and interception percentage. QBR is a more complex, proprietary metric from ESPN that attempts to factor in game context like down, distance, and opponent strength.
Q: Can a quarterback have a high completion percentage but still play poorly?
A: Yes. A quarterback can “check down” frequently, throwing very short, safe passes that are easy to complete but don’t gain many yards or help the team win. This might result in a high Pass Completion Percentage but a low yards-per-attempt average and few points scored.
Q: Who holds the NFL record for single-season Pass Completion Percentage?
A: As of the end of the 2023 season, Drew Brees holds the record, completing 74.4% of his passes in the 2018 season.
Q: Does this calculator work for college football too?
A: Yes, the formula for Pass Completion Percentage is the same across all levels of football, from high school to college to the pros.
Q: Why is Pass Completion Percentage important for fantasy football?
A: In many fantasy leagues, especially those with “point per reception” (PPR) scoring, quarterbacks with a high Pass Completion Percentage are very valuable. Their consistent connections generate a steady stream of points for both the QB and their receivers. It’s a key stat for Fantasy Football Projections.
Q: Where can I find historical data on this metric?
A: Many sports statistics websites provide extensive databases. For official league data, exploring Historical NFL Data sources is the best approach for detailed analysis of Pass Completion Percentage across different eras.
