FAQ
In baseball statistics, Earned Run Average, or ERA, is one of the most well-known pitching statistics and represents the average number of earned runs a pitcher will give up per nine-inning game. It is determined by dividing the total number of earned runs allowed by the number of innings pitched and multiplying by nine.
The ERA is calculated using the following formula:
ERA = 9 × Earned Runs Allowed / Innings Pitched
For example, a pitcher who allows 3 earned runs in 7 innings pitched would have an ERA of 3.86 (9 × 3/7).
