## Quick Answer

Calculate a pitcher's Earned Run Average (ERA). Enter earned runs allowed, innings pitched, and game length to see the average runs allowed per game.

## Definition

An ERA calculator is a baseball statistics utility used to compute a pitcher's Earned Run Average, which represents the mean number of earned runs allowed per standard game. Typically set to nine innings for professional leagues and seven innings for softball or youth divisions, this metric scales runs allowed to match the total game duration. By dividing total earned runs by innings pitched and multiplying by standard game length, it provides a standardized evaluation of pitching performance. Coaches, analysts, and players use this calculator to assess pitching efficiency, rank player value, and track seasonal progress.

## How to Use

1. **Enter earned runs** — Type the total number of earned runs allowed by the pitcher in the input field.
2. **Input innings pitched** — Enter the total innings pitched, using standard decimal outs notation for any partial innings.
3. **Select game length** — Choose the standard game length of either nine or seven innings depending on your league.
4. **Review your ERA** — Read the calculated Earned Run Average along with its performance rating classification.
