An ERA calculator is a tool used to calculate the Earned Run Average in baseball, softball, or cricket. The ERA represents a pitcher’s effectiveness by determining the average number of earned runs they give up per innings pitched.
The formula for calculating ERA is (earned runs / innings pitched) multiplied by a standard number of game innings (e.g., 9 innings in baseball).
For example, if a pitcher has given up 10 earned runs in 50 innings pitched, their ERA would be 1.80. The ERA calculator helps assess a pitcher’s performance and compare it to others by providing a numerical measure of their effectiveness on the field.
