Decoding 158.3
Few numbers in sport are as quoted yet as misunderstood as the NFL passer rating. Adopted by the league in 1973, it distils a quarterback’s passing line into a single figure on a curious scale that tops out at 158.3 rather than a round 100. This calculator computes that official rating exactly, from the five box-score inputs that feed it — attempts, completions, passing yards, touchdowns and interceptions — and then opens up the formula so you can see precisely how the number was built.
Under the hood, the rating is the average of four components, each measuring a per-attempt rate: how often passes are completed, how many yards each attempt gains, how frequently attempts become touchdowns, and how rarely they are intercepted. Each component is scaled and then clamped between zero and 2.375 — a deliberate cap that prevents any single category from running away with the score in a small sample. The four capped values are summed, divided by six and multiplied by a hundred, which is why a flawless performance in all four caps out at exactly 158.3. The component bars in this tool show each of those four pieces on its own 0–2.375 scale, making it obvious whether a rating is being lifted by efficient completions or dragged down by interceptions.
It helps to know what the rating is not. It measures passing production only, ignoring rushing yards, sacks, fumbles and the game situation entirely — a quarterback can post a gaudy rating in a blowout or a pedestrian one while leading a gritty comeback. It is also distinct from the NCAA’s college passer-efficiency formula, which weights the same stats differently and runs on a higher scale, and from ESPN’s Total QBR, a modern, opponent-adjusted metric on a 0–100 scale. As a quick, transparent and historically consistent summary of passing efficiency, though, the traditional rating remains the common language of football statistics. Whether you are settling a debate about a single game or comparing seasons, this calculator gives you the exact figure and shows its work — all computed in your browser, with nothing sent anywhere.
Four capped components, each worth up to 2.375 — add them, divide by six, times a hundred, and a perfect day is 158.3.
10 Facts About Passer Rating
The NFL passer rating runs from 0 to 158.3.
A flawless 158.3 needs near-perfect numbers in all four parts.
It blends completions, yards, touchdowns and interceptions.
Each of the four components is capped at 2.375.
The formula has been used by the NFL since 1973.
The NCAA uses a different college passer-efficiency formula.
It ignores rushing, sacks and game situation.
A rating above 100 is generally considered excellent.
The ESPN “QBR” is a separate, more modern metric.

Frequently Asked Questions
- It is built from four components, each based on per-attempt rates: completion percentage, yards per attempt, touchdown percentage, and interception percentage. Each component is scaled and then capped between 0 and 2.375. The four are added, divided by six and multiplied by 100, giving a number between 0 and a maximum of 158.3.
- A perfect rating is 158.3. To reach it, a quarterback needs all four components maxed out at 2.375, which in practice means a completion percentage of 77.5% or higher, at least 12.5 yards per attempt, a touchdown on at least 11.875% of attempts, and zero interceptions. It is rare and usually only achievable over a smaller number of attempts.
- The cap stops any single category from dominating the rating. Without it, a quarterback could post an absurd yards-per-attempt figure in a tiny sample and distort the whole score. By limiting each of the four parts to a maximum of 2.375, the formula keeps the rating balanced and bounded at 158.3.
- As a rough guide, a rating above 100 is considered excellent, the 90s are very good, the 80s are a solid starter, the 70s are below average, and below 70 is poor. League-average ratings have crept upward over the decades as passing offences have evolved, so context and era matter when comparing quarterbacks.
- No. The passer rating measures only passing production — attempts, completions, yards, touchdowns and interceptions. It ignores rushing yards, rushing touchdowns, sacks taken, fumbles and the game situation. That is one of its main limitations and why modern metrics like ESPN’s Total QBR were created to give a fuller picture.
- No. College football uses the NCAA passer-efficiency rating, which weights the same statistics differently and is not capped the same way, so its scale runs higher. This calculator implements the professional NFL formula, so do not compare its output directly with college passer-efficiency numbers.
- The passer rating here is the traditional, purely statistical formula based on five box-score inputs. ESPN’s Total QBR is a proprietary, opponent- and situation-adjusted metric on a 0–100 scale that also factors in rushing and the leverage of each play. The two answer different questions; this tool computes the classic, transparent passer rating.
- Both. Enter the attempts, completions, yards, touchdowns and interceptions for any span — a single game, a season, or a career — and the formula applies identically. Just be aware that small samples can produce extreme ratings, including perfect ones, which is normal given how the per-attempt rates behave.
- They display each of the four capped components on its 0–2.375 scale, so you can see exactly which categories are driving or dragging the rating. A short bar reveals a weakness — too many interceptions, say, or too few yards per attempt — while four full bars indicate a perfect 158.3.
