What does the NFL passer rating calculator measure?

It calculates the official NFL passer rating on a 0–158.3 scale from completion rate, yards per attempt, touchdown rate, and interception rate.

Is this the same as ESPN QBR?

No. It calculates the public NFL passer rating, not ESPN's proprietary QBR.

How is MLB ERA calculated?

ERA is calculated as 9 × earned runs ÷ innings pitched.

How is WHIP calculated?

WHIP is calculated as (walks + hits) ÷ innings pitched.

What does 7.2 innings pitched mean?

In baseball notation, 7.2 means 7⅔ innings, not 7.2 standard decimal innings.

NFL Passer Rating & MLB ERA/WHIP Calculator

Compute the official NFL quarterback passer rating (0–158.3) with component breakdown, and MLB pitching stats ERA and WHIP with baseball innings notation.

Details

What this tool helps you do

Two classic US-sports stats in one calculator. NFL passer rating uses the official four-component formula (each clamped to [0, 2.375], combined ((a+b+c+d)/6)×100) on a 0–158.3 scale — this is the public NFL passer rating, not ESPN's proprietary QBR. MLB mode computes ERA = 9×ER/IP and WHIP = (BB+H)/IP with correct baseball innings parsing (7.1 = 7⅓, 7.2 = 7⅔). Includes contextual tiers. For batting (AVG/OBP/SLG) use the Baseball Stats tool.

Passer rating: 25 ATT, 20 COMP, 285 YDS, 3 TD, 0 INT

A near-perfect game — 80% completions, 11.4 yards per attempt, 3 touchdowns and no interceptions gives a passer rating of 153.75 (Elite band), with the completion AND touchdown components both clamped at the 2.375 maximum.

<section>Passer rating 153.75 (Elite) · a=2.375 b=2.100 c=2.375 d=2.375</section>

Pitching: 7.2 IP (7⅔), 3 ER, 5 H, 2 BB

A quality start with baseball innings notation: 7.2 IP parses as 7⅔ innings, giving ERA 3.52 (mid-rotation) and WHIP 0.91 (excellent) alongside H/9 and BB/9.

<section>ERA 3.52 · WHIP 0.91 · 7.2 IP = 7.667 innings</section>
