If you want to play a sport, act as an analyst or perform any other activity related to the sport, it is important to get some key related details. We can take the example of baseball. If you are a player, you need to know about the basics of the game. For instance, a standard game of baseball has 9 innings. Thus, when the ERA is calculated, the total number of innings considered in the formula is 9. However, soft ball tournaments comprise of 7 innings per game. These games have a reduced number of innings because they are mostly played by amateurs and inexperienced players.

The ERA calculation of 7 innings game

When you talk about a game that has 7 innings, the formula of ERA does not differ and the basic methodology remains unchanged. The only difference is that when you calculate the ratio of “earned runs” and “innings pitched”, it is multiplied by 7 instead of 9. The reason is that the game has 7 innings. This aspect has to be incorporated in the formula properly otherwise incorrect results would be produced. 

Calculating Era for a 7 innings game

Formula of ERA for 7 innings game

The formula which you need to use to calculate ERA for a 7 innings game is shown below

ERA = (Earned Runs / Innings Pitched)*7


  • The interpretation of the ERA formula is very simple. To start with, you have to calculate the ratio of Earned Runs and Innings Pitched. This is obviously calculated when you divide earned runs by innings pitched.


Consider an example.

Let us take Earned Runs = 100 and Innings Pitched = 10. Considering these values, the ERA for 7 innings would be given as 

ERA = (100/10)*7

ERA = 70

If the ERA was being calculated for a standard baseball game, the number of innings would have been 9 instead of 7.
