The QB Calculator is a powerful online sports analytics tool designed to evaluate a quarterback’s performance using key football statistics. Whether you are a coach, analyst, fantasy football player, or a passionate fan, this tool helps you quickly understand how effective a quarterback is on the field.
QB Calculator
Instead of manually calculating complex performance metrics, this tool automatically processes inputs like completions, attempts, passing yards, touchdowns, and interceptions to generate meaningful insights such as completion percentage, yards per attempt, touchdown rate, interception rate, and a simplified QB rating.
This makes it easier to compare players, track performance trends, and make informed decisions in football analysis or fantasy leagues.
What is a QB Calculator?
A QB Calculator is an online statistical tool that evaluates a quarterback’s efficiency based on passing performance data.
It helps calculate:
- Completion Percentage
- Yards Per Attempt (YPA)
- Touchdown Rate
- Interception Rate
- Simplified QB Rating
These metrics are widely used in American football to measure how well a quarterback performs in real game situations.
Why QB Performance Metrics Matter
Quarterback performance is not just about throwing touchdowns. It involves consistency, accuracy, decision-making, and risk management.
Key reasons these metrics are important:
- Completion percentage shows accuracy
- Yards per attempt shows efficiency
- Touchdown rate shows scoring ability
- Interception rate shows risk level
- Overall rating gives combined performance insight
Together, they provide a complete picture of a quarterback’s effectiveness.

Formula Used in QB Calculator
The QB Calculator uses standard football statistical formulas combined into a simplified performance rating system.
1. Completion Percentage
Completion % = (Completions ÷ Attempts) × 100
2. Yards Per Attempt (YPA)
YPA = Passing Yards ÷ Attempts
3. Touchdown Rate
TD Rate = (Touchdowns ÷ Attempts) × 100
4. Interception Rate
INT Rate = (Interceptions ÷ Attempts) × 100
5. Simplified QB Rating Formula
QB Rating =
(Completion % × 0.3) + (YPA × 10) + (TD Rate × 0.25) − (INT Rate × 0.5)
This formula balances accuracy, efficiency, scoring ability, and mistakes to give a quick performance overview.
Example QB Calculation
Let’s understand with an example:
- Completions: 25
- Attempts: 40
- Passing Yards: 320
- Touchdowns: 3
- Interceptions: 1
Step-by-step calculation:
- Completion % = (25 ÷ 40) × 100 = 62.5%
- YPA = 320 ÷ 40 = 8.0
- TD Rate = (3 ÷ 40) × 100 = 7.5%
- INT Rate = (1 ÷ 40) × 100 = 2.5%
QB Rating:
(62.5 × 0.3) + (8 × 10) + (7.5 × 0.25) − (2.5 × 0.5)
= 18.75 + 80 + 1.875 − 1.25
= 99.38
QB Performance Example Table
| Completions | Attempts | Yards | TDs | INTs | Comp % | YPA | TD Rate | INT Rate | QB Rating |
|---|---|---|---|---|---|---|---|---|---|
| 20 | 30 | 250 | 2 | 1 | 66.67% | 8.33 | 6.67% | 3.33% | 92.45 |
| 25 | 40 | 320 | 3 | 1 | 62.50% | 8.00 | 7.50% | 2.50% | 99.38 |
| 30 | 45 | 380 | 4 | 0 | 66.67% | 8.44 | 8.89% | 0.00% | 108.22 |
| 18 | 28 | 210 | 1 | 2 | 64.29% | 7.50 | 3.57% | 7.14% | 84.10 |
| 22 | 35 | 290 | 2 | 3 | 62.86% | 8.29 | 5.71% | 8.57% | 87.33 |
