(Earned Run Average) ERA Calculator

What is ERA Calculator?

ERA stands for Earned Run Average and is a statistic used in baseball to measure the effectiveness of a pitcher. The ERA Calculator is a tool used to calculate a pitcher’s ERA based on the number of earned runs, innings pitched, and the total innings in a game.

The formula for calculating the Earned Run Average (ERA) is:

ERA = (earned runs / innings pitched) * game innings

where “earned runs” is equal to the total runs scored against the pitcher minus the runs scored due to errors, “innings pitched” is the total number of innings the pitcher has pitched, and “game innings” is the total number of innings in a game.

To calculate the ERA, first, you need to determine the earned runs by subtracting runs scored due to errors from the total runs scored against the pitcher. Then, divide the earned runs by the number of innings pitched and multiply the result by the total innings in a game. The resulting value is the pitcher’s ERA.

How to Calculate Earned Run Average?

To calculate the ERA, you will need the following information:

Earned Runs: The number of runs scored against the pitcher that were not due to errors.
Innings Pitched: The total number of innings the pitcher has pitched.
Game Innings: The total number of innings in a game, typically nine.

Once you have this information, you can use the following steps to calculate the pitcher’s ERA:

Determine the earned runs by subtracting the runs scored due to errors from the total runs scored against the pitcher.
- Earned Runs = Total Runs – Runs Due to Errors
Divide the earned runs by the innings pitched.
- Earned Runs / Innings Pitched = ER/IP
Multiply the result by the total innings in a game.
- (ER/IP) * Game Innings = ERA
Round the ERA to two decimal places for easier interpretation.
