How to Calculate Your Bowling Average

Bowling averages are essential in league play, especially handicap leagues, since your average is needed to determine your handicap. The United States Bowling Congress doesn't officially recognize an average until you've bowled 12 games, but you can calculate your average based on any number of games.
Difficulty: Easy
Time Required: A few minutes
Here's How:

Bowl. To calculate an average, you need some scores.
Add your scores. Say you bowl three games of 150, 181 and 136. Add those scores.

150 + 181 + 136 = 466

Divide by the number of games. In this example, you bowled three games, so you divide 466 by 3.

466 ÷ 3 = 155 1/3

Round down. Bowling scores are typically rounded down, ignoring anything on the right side of the decimal point. In this case, your average is 155.
