⚾ What is ERA?

ERA (Earned Run Average) is one of the most important stats for evaluating a pitcher’s performance in baseball. It tells you how many earned runs a pitcher allows per standard game (usually 9 innings). A lower ERA indicates better pitching performance.

 ERA Formula:

We use the standard ERA formula:

$$ERA=\left(\frac{\text{Earned Runs}}{\text{Innings Pitched}}\right)\times \text{Game Innings}$$

Since each inning consists of 3 outs, this calculator uses:

$$\text{Innings Pitched}=\frac{\text{Total Outs Pitched}}{3}$$

So you can just enter total outs (like 197), and we’ll handle the rest.

💡 Example:

• Earned Runs: 15

• Total Outs Pitched: 197

• Game Innings: 9
  → Innings = 65 + 2/3
  → ERA = (15 / 65.67) × 9 = 2.06
