Batting average

42

420 runs ÷ 10 dismissals.

Strike rate
140
Runs per innings
35

How we got this

  1. 12 innings − 2 not out = 10 dismissals
  2. 420 ÷ 10 = 42
  3. Strike rate: 420 × 100 ÷ 300 = 140

Average and strike rate answer different questions

Average is how many runs a batter makes before getting out. Strike rate is how quickly they make them. A good T20 batter needs both.

What this calculator does not account for

  • Retired hurt or retired out, which competitions record differently.
  • Quality of opposition and conditions.
  • Very few dismissals, where one innings swings the average a lot.

How this is calculated

Formula: Batting average and strike rate

average =runs ÷ (innings − not outs) ; strike rate =runs × 100 ÷ balls

What the symbols mean

  • runsRuns off the bat across the innings.
  • inningsInnings batted.
  • not outsInnings that ended without a dismissal.
  • ballsBalls faced, including no-balls but not wides.

Good to know

  • A batter who has never been out has no average yet; scorecards show a dash.
  • Strike rate is runs per 100 balls, so higher is faster.

Worked examples

Each example is worked out by the same code as the calculator above.

420 runs, 12 innings, 2 not out

12 − 2 = 10 dismissals. 420 ÷ 10 = 42. Off 300 balls the strike rate is 140.

120 runs, 5 innings, 4 not out

Only 1 dismissal, so the average is 120, even though no innings may have reached 120.

Questions

Why divide by dismissals and not innings?

A not-out innings did not end in failure, so it adds its runs but not a dismissal. That is how cricket has always kept averages.

What is a good batting strike rate?

Around 50 to 60 is normal in Tests, 85 to 100 is good in one-day cricket and 130 to 150 or more in T20.

Can my average be higher than my top score?

Yes, if you have many not-outs. 120 runs in 5 innings with 4 not-outs is an average of 120.
