Bowling Average Calculator (Cricket)

Bowling average is a statistical measure of a bowler's effectiveness. It represents the number of runs a bowler concedes for every wicket they take. A lower bowling average indicates better performance, as it means the bowler is taking wickets while giving away fewer runs.

The formula is simple: Bowling Average = Runs Conceded ÷ Wickets Taken. For example, if a bowler has conceded 300 runs and taken 20 wickets, their bowling average is 300 ÷ 20 = 15.00. This means they give away 15 runs per wicket on average.

Generally, a bowling average below 20 is considered excellent at the international level, 20–25 is very good, 25–30 is good, and above 30 is considered average or poor. Context matters too — formats like T20 tend to produce higher averages than Test cricket.

Bowling average provides a direct measure of a bowler's cost-effectiveness — how many runs they surrender for each wicket. It helps coaches, selectors, and analysts compare bowlers across different matches and series, making it one of the most widely referenced performance metrics in cricket.

Bowling average measures runs conceded per wicket, while bowling strike rate measures the number of balls bowled per wicket. A bowler can have a great strike rate (taking wickets frequently) but a poor average if they concede too many runs. Both stats together give a fuller picture of bowling performance.

Economy rate measures runs conceded per over (6 balls), reflecting how many runs a bowler gives away regardless of wickets. Bowling average focuses specifically on the cost per wicket. A bowler can be economical (low economy rate) but still have a high bowling average if they rarely take wickets.

Among legends, George Lohmann holds one of the best Test bowling averages at around 10.75. In modern cricket, Joel Garner, Malcolm Marshall, and Curtly Ambrose all maintained averages in the low 20s over long careers. Shane Warne and Muttiah Muralitharan, despite being spinners, also maintained excellent averages below 25.

No — mathematically, dividing by zero is undefined. A bowling average can only be calculated once a bowler has taken at least one wicket. Until then, the statistic is simply recorded as 'N/A' or not applicable.
