Batting Average Calculator

Divide total runs by the number of times the batter has been dismissed. Dismissals are innings batted minus not outs, so a player with 1,200 runs from 40 innings including 5 not outs has 35 dismissals and averages 34.29. Dividing by innings instead of dismissals is the common error and always produces a lower figure.

Not as dismissals, no. The runs from a not-out innings are still added to the total, but the innings itself is removed from the divisor. That is why not outs push an average up. A batter unbeaten in every innings has no completed dismissals at all, so their average is undefined rather than infinite.

In Test cricket, above 40 is solid, above 50 marks a top-class career and above 60 is exceptional. In one-day cricket the equivalent bands sit roughly five to ten runs lower. In Twenty20 the average means little without the strike rate beside it, because scoring quickly matters more than batting long.

Yes. A batter who retires hurt and does not return is recorded as not out, because they were not dismissed. Retired out is different: that is treated as a dismissal and counts in the divisor.

Almost always because of not outs, or because the innings count includes matches where the batter did not bat. Check that you are counting innings batted rather than matches played, and that every unbeaten innings is in the not-out column.

Yes, and it counts twice over. A duck adds nothing to the runs column and still adds one to the dismissals column, so it drags the average down harder than a low score does. A golden duck and a nought off forty balls are identical to the arithmetic. Only a not-out nought escapes, because the batter was never dismissed.

Donald Bradman's 99.94 from 52 Tests, a figure no qualifying batter has approached before or since. The second tier of Test history sits in the low to mid sixties, which is the gap that makes the number famous. He needed four runs in his final innings to average 100 and was dismissed for nought.

Most record lists set a qualification of around twenty innings, and the reason is visible in the arithmetic: at five innings one unbeaten century can double an average. Below about twenty the figure describes a run of form rather than a player. Published career tables state their threshold, and a table without one is not worth reading.

The formula is identical — runs divided by dismissals — but it carries much less meaning. A T20 innings is short and ends when the overs do, so not outs are common and averages inflate. A finisher regularly unbeaten on 20 can out-average an opener making 40 every week, which is why T20 is judged on strike rate first.
