Definition
Bowling economy rate is the average number of runs a bowler concedes per over. It describes how costly a spell was in runs, but it does not tell the whole story about wickets, pressure or the role the bowler was asked to play.
Formula
Bowling economy = runs conceded ÷ overs bowled. Convert any partial over using legal balls. Four overs and two balls equals 26 legal balls, which is 26 ÷ 6 = 4.3333 overs mathematically.
Worked example
A bowler concedes 24 runs in 4 overs. Divide 24 by 4 and the economy rate is 6.00 runs per over. If 24 runs were conceded in 4 overs and 2 balls, divide by 4.3333 overs instead; the rate is approximately 5.54.
Use the right runs figure
Scorecards distinguish team extras and the runs charged to a bowler. Some extras are not charged to the bowler, so use the bowling figures from the scorecard rather than assuming all team extras count in the same way.
Read economy in context
A lower economy means fewer runs conceded per over in the period measured. A bowler may also be judged by wickets, dot balls, boundary prevention and pressure created. Match phase, field placements, pitch and the required rate can influence a bowler's task.
Common errors
Do not enter 4.2 as 4.2 decimal overs. Do not count a partial over as a complete over. Do not compare bowlers without checking whether the figures cover similar formats, phases and roles.
