What this calculator does
This tool combines the two headline cricket statistics for an all-rounder in one place: the batting average (how many runs you score per time you are dismissed) and the bowling economy rate (how many runs you concede per over bowled). It also derives your runs conceded per ball, so you can compare batting output against bowling tightness at a glance.
How it works
Enter your total runs scored and the number of times you have been dismissed to get the batting average. Enter the runs you conceded, the number of completed overs you bowled, and any extra balls from an unfinished over to get the economy rate. A cricket over is six legal deliveries, so three extra balls count as half an over.
Formula
Batting average is total runs divided by dismissals:
Overs bowled converts a part-over into a decimal using six balls per over, and economy rate is runs conceded divided by that figure:
$$\text{Overs Bowled} = \text{Completed Overs} + \frac{\text{Extra Balls} }{6}$$ $$\text{Economy Rate} = \frac{\text{Runs Conceded} }{\text{Overs Bowled} }$$Runs conceded per ball is the economy rate spread across the six balls of an over:
$$\text{Runs per Ball} = \frac{\text{Economy Rate} }{6}$$Worked example
Suppose a player has scored 462 runs and been dismissed 11 times. The batting average is 462 / 11 = 42.0 runs per dismissal. With the ball, they conceded 48 runs from 10 completed overs with no extra balls, so overs bowled is 10.0 and the economy rate is 48 / 10 = 4.8 runs per over. Runs per ball is 4.8 / 6 = 0.8.
FAQ
What counts as a good batting average? In Test cricket a career average above 50 is regarded as excellent and 40 to 50 is very good; in limited-overs formats the benchmarks are lower because innings are shorter.
Why is a cricket over six balls? Under the modern Laws of Cricket an over is six legal deliveries. Wides and no-balls do not count toward the six, which is why economy is measured per completed over of six balls.
How do I enter part of an over? If you bowled 9 overs and 3 balls, enter 9 as completed overs and 3 as extra balls. The tool converts this to 9 + 3/6 = 9.5 overs before calculating the economy rate.
