NFL Passer Rating Calculator Description

What is the NFL Passer Rating?

The NFL passer rating is a statistical formula used to assess the performance of quarterbacks by converting their passing stats into a single, standardized number.

Core Metrics Involved

• Completion Percentage
• Yards Per Attempt
• Touchdowns Per Attempt
• Interceptions Per Attempt

Mathematical Formula

Component A = ((Completions / Attempts) - 0.3) * 5
Component B = ((Yards / Attempts) - 3) * 0.25
Component C = (Touchdowns / Attempts) * 20
Component D = 2.375 - ((Interceptions / Attempts) * 25)

Each component is capped between 0 and 2.375.

Passer Rating = ((A + B + C + D) / 6) * 100

Key Insights

• The formula blends accuracy, efficiency, scoring, and ball security into a unified score.
• Each stat is normalized to reduce bias toward any single metric.
• It does not account for rushing performance or game context.

Edge Cases to Know

• 0 Attempts: Rating is undefined; division by zero occurs.
• No TDs or INTs: High rating still possible with strong accuracy and yardage.
• Yardage without Efficiency: High yards alone won’t boost rating if accuracy is poor.
• Perfect Game: Achieved by hitting the cap in all four formula components.
• Component Clipping: Any negative component is automatically set to 0.
