Higher is better. The metric shows how often pass attempts become completions.

What is Completion Percentage in Football?

Completion percentage is the share of pass attempts that end in a completed pass. It is one of the fastest ways to measure quarterback accuracy, timing, and short-to-intermediate efficiency.

Coaches, analysts, and fantasy football players use completion rate to compare passing consistency from one game to the next. A high number usually means the quarterback is keeping the offense on schedule.

This stat also feeds directly into the official NFL passer rating formula, where the completion component rewards accurate passers and penalizes inefficient ones.

Completion Percentage Formula

Completion Percentage FAQ

Frequently Asked Questions

Everything you need to know about passer rating and how to calculate it.

What is a good completion percentage for a quarterback?

In modern football, 65% or better is usually considered strong. Around 60% is serviceable, while anything below 55% often signals inefficient passing.

Does completion percentage measure deep passing ability?

Not by itself. A quarterback can complete a high share of short throws without creating explosive plays. That is why yards per attempt should also be considered.

Is completion percentage part of passer rating?

Yes. The official NFL passer rating includes a completion percentage component, so higher accuracy directly improves the final rating.

Can completion percentage be misleading?

Yes. Checkdown-heavy offenses can inflate completion rate without producing many yards. It works best alongside yards per attempt, touchdown percentage, and interception percentage.
