Calculate unadjusted football passing yards per attempt, compare next-attempt scenarios, or find the minimum whole-yard total needed for a target YPA.

Required: official passing yards and pass attempts from the same scope.

The result rounds up to the minimum whole passing-yard total that meets the target.

Yards Per Attempt Formula

Passing yards per attempt, commonly abbreviated YPA, divides official passing yards by official pass attempts:

YPA = (Passing Yards) / (Pass Attempts)

The NCAA passer-efficiency instructions use this same yards-per-attempt quantity before multiplying it by 8.4 as one component of the college rating.

Why Attempts, Not Completions?

YPA evaluates production across every official pass attempt, including incomplete and intercepted passes. Dividing by completions instead calculates yards per completion, which answers a different question and will normally be higher.

Plain YPA vs. Adjusted Passing Metrics

Plain YPA uses only yards and attempts. Adjusted yards per attempt adds a touchdown bonus and an interception penalty. Adjusted net yards per attempt also accounts for sacks. NCAA passer efficiency combines YPA with completion, touchdown, and interception percentages. These metrics should not be labeled interchangeably.

Finding the Yardage Needed for a Target

Target mode rearranges the formula:

Passing Yards = Target YPA × Pass Attempts

Because an official total is recorded in whole yards, the calculator rounds upward to the minimum whole-yard total that meets the target and then verifies the achieved YPA.

Example

A passer with 1,567 yards on 166 attempts has 1,567 divided by 166, or approximately 9.44 yards per attempt. In target mode, 8.5 YPA across 35 attempts requires exactly 297.5 mathematical yards, so at least 298 official passing yards are needed.

One-Attempt Sensitivity

The result card shows what happens if the next official attempt gains zero yards or ten yards. This is especially useful in small samples, where one play can move the average more than it would over a full season.

Assumptions and Limitations

  • Passing yards and attempts must cover the same player or team and the same set of games.
  • The formula does not evaluate down, distance, opponent, air yards, yards after catch, touchdowns, interceptions, or game situation.
  • Sacks are not included in plain NFL YPA; use a net passing metric when sack yardage belongs in the analysis.
  • Negative official passing-yard totals are mathematically valid, although uncommon over a large sample.
