Yards per carry is rushing yards divided by carries, and because it is a plain average, a single long run can change it more than any other carry in the game. Here is how the number is built, and what it looks like with and without one big play.
What the formula does
YPC = Rushing Yards ÷ Carries
A carry is, in the glossary's words, "a statistic referring to the number of times a rushing player attempts to advance the ball." Every carry goes in the denominator whether it gained 12 yards, none, or lost 3. The numerator is the sum of all those yards. The Yards per Carry Calculator uses exactly this division and nothing else: no cap on any single play, no weighting.
That absence of a cap is the point of this guide: every yard counts at face value, so a 60-yard run adds 60 to the numerator.
Worked example: the same total, two stories
The Wikipedia article on rushing gives the sentence "the running back had 20 carries for 100 rushing yards." Take that stat line:
YPC = 100 ÷ 20 = 5.0
The line alone does not say how the 100 yards arrived. Consider two ways it could have happened. These are illustrative stat lines, not a real player's game.
| Version | Carries | Yards | YPC |
|---|---|---|---|
| Even: every carry gains 5 yards | 20 | 100 | 5.0 |
| One 60-yard run, 19 other carries | 20 | 100 | 5.0 |
| Same game without the 60-yard run | 19 | 40 | 2.1 |
The two versions are identical to the calculator: 100 ÷ 20 = 5.0. Remove the 60-yard carry from the second and the remaining 19 carries gained 40 yards, so 40 ÷ 19 = 2.105, which rounds to 2.1. One play accounts for 60 of the 100 yards and moves the average by roughly 2.9 yards per carry.
Why the sample size matters
With 20 carries, one play is 5% of the attempts and 60% of the yards in the example above. With 200 carries and the same 60-yard run, it is 0.5% of the attempts, so it moves the average by far less. Assume a back has 200 carries for 800 yards including that run: 800 ÷ 200 = 4.0, and without it, 740 ÷ 199 = 3.72. The gap is about 0.3 yards per carry, not 2.9. (These figures are illustrative arithmetic, not a real season.)
The longer the sample, the less any one play can do. A single game's YPC is the number most open to being a one-play story.
What the number can and cannot tell you
- It is volume-neutral. Total rushing yards rewards touches; YPC divides them back out. Two backs with the same YPC can have very different workloads.
- It does not show the shape of the runs. The table above has one YPC for two very different games. If you want that shape, look at the carry-by-carry log, not the average.
- It inherits its source's counting rules. The calculator divides whatever totals you enter. If a source counts or excludes certain plays differently from another, the YPC will differ, and the calculator cannot tell which convention you used.
To check your own numbers, enter the yards and carries into the Yards per Carry Calculator, then try removing the longest run to see how much of the average it carried.
