Batting Average Calculation Explained: Why 50 Is Elite, Not Outs, and Don Bradman's 99.94
Cricket batting average — how it is calculated (runs divided by times dismissed, NOT total innings), why 'not out' innings are excluded from the denominator, what average 50 means (elite), 40 (good), 30 (moderate), and why Don Bradman's 99.94 is statistically the most extraordinary achievement in cricket (the next-highest career average of 60+ is for players with far fewer innings).
Batting average in cricket is the total runs scored divided by the number of times the batsman was dismissed — not the total number of innings. This distinction matters: a batsman who is not out at the end of an innings still contributes those runs to the numerator but does not add to the denominator (dismissed count). The formula: Total runs / Times dismissed = Average. A batsman with 1,000 runs in 25 innings who was not out in 5 of those innings has an average of 1,000 / 20 = 50.00.
Why Not Outs Skew the Average
The not-out effect on batting average: (1) Finisher effect: batsmen who specialise in finishing innings (entering late, with a result already determined) often have unnaturally high not-out percentages — they are 'stranded' not out when the innings ends (not because they batted exceptionally, but because the match ended). This inflates their average. MS Dhoni has a career ODI average of 50.57 — but approximately 25% of his innings were not outs. His adjusted average (if not outs were counted as dismissals) would be lower; (2) True career assessment: Bradman's 99.94 average (already accounting for not outs) is calculated on 80 innings, 10 not outs (so 70 dismissals). His total runs were 6,996. Average = 6,996 / 70 = 99.94. If not outs had counted as dismissals, Bradman's average would be 6,996 / 80 = 87.45 — still extraordinary; (3) The ODI average inflation: in ODI cricket, the last 2-3 batsmen in the order frequently finish not out (the innings ends at 50 overs, not when the last wicket falls). This means No. 7-11 batsmen in ODI cricket often have disproportionately high averages that do not reflect their dismissal rate against quality bowling.
Don Bradman's 99.94: The Statistical Impossible
Bradman's career Test average analysis: (1) The career: 80 Test innings, 6,996 runs, 10 not outs, 70 dismissals. Average = 99.94. Career from 1928 to 1948; (2) The final innings: Bradman needed just 4 runs in his final Test innings (The Oval, 1948, vs England) to retire with a 100.00 average. He was bowled by Eric Hollies for 0 — the famous duck that brought his average to 99.94 instead of 100.00. The story of the duck is one of cricket's most poignant — the greatest batsman, playing his final innings, needing just 4, dismissed without scoring; (3) The statistical gap: the next-highest Test career average for a player with 50+ Tests is approximately 60-61 (George Headley of West Indies, 60.83; Herbert Sutcliffe of England, 60.73; Eddie Paynter of England, 59.23; Graeme Pollock of South Africa, 60.97). These are extraordinary averages — but Bradman's 99.94 is 39+ above the next-best sustained average. No other sport has a comparable statistical dominance (a player averaging 2x the level of the 2nd-best sustained performer); (4) The era adjustment debate: some analysts argue that Bradman's era (1928-1948) featured weaker bowling (uncovered pitches, no helmets, no reverse swing, no complex field-setting analytics). However, Bradman scored on uncovered pitches too — and managed 99.94 on them. The era argument reduces his achievement marginally but does not explain a 39-point gap to the 2nd-best.
ODI and T20 Batting Averages
Average in limited-overs formats: (1) ODI batting average: the top ODI batsmen in history (by average with 50+ ODIs): Michael Bevan (Australia, 53.58 — a finisher specialist whose career average was inflated by not outs), MS Dhoni (50.57, with significant not-outs), Virat Kohli (58.69 with fewer not-outs — the highest adjusted ODI average of any player with 100+ ODIs), Babar Azam (57+), Sachin Tendulkar (44.83 across 463 ODIs — a long career average), Joe Root (54+), Ross Taylor (NZ, 48+); (2) T20I batting average: T20I averages are typically lower than ODIs because T20 batsmen take more risks, get out more frequently, and play in formats where 25-30 off 15 balls (a dismissal in that context) might have been a good innings. Elite T20I batsmen average 35-45. Below 25 T20I average is unacceptable for a top-order specialist; (3) The 'average x strike rate' composite: some analysts use Average x Strike Rate as a composite metric — a player averaging 40 at 150 strike rate = composite 6,000; a player averaging 50 at 100 strike rate = composite 5,000. The higher the composite, the more value the batsman adds. Virat Kohli's ODI composite (58.69 average x 93.17 strike rate = approximately 5,470) is one of the highest sustained composites in ODI history.
Frequently asked questions
How is batting average calculated in cricket?
Batting average in cricket is calculated as: total runs scored divided by the number of times dismissed (not total innings). Not-out innings are included in the runs total but NOT in the dismissal count. Formula: Batting average = Total runs / Number of dismissals. Example: a batsman who scores 1,000 runs in 25 innings, being not out 5 times, has average = 1,000 / (25-5) = 1,000 / 20 = 50.00. This calculation method means not-out innings artificially inflate the average — batsmen who are frequently not out (such as lower-order finishers) often have higher averages than their actual performance against quality bowling suggests.
What is a good batting average in Test cricket?
Test cricket batting averages by tier: Below 25 — lower-order batsman; 25-34 — modest, struggles vs quality bowling; 35-44 — competitive (most working Test batsmen); 45-50 — good, consistent top-7 performer; 50-55 — elite (Tendulkar 53.78, Dravid 52.31, Sangakkara 57.40); 55-60 — exceptional (Kallis 55.37, Hammond 58.45); 60+ — historically extraordinary (George Headley 60.83, Sutcliffe 60.73); 99.94 — Don Bradman, the statistical outlier by approximately 39 points above the next-best sustained career average. A Test batting average of 50+ is the accepted benchmark for 'great' batsman status.
Why is Don Bradman's average 99.94 and not 100?
Don Bradman needed just 4 runs in his final Test innings (The Oval, 1948 — Australia's Invincibles tour of England) to retire with a 100.00 Test batting average. He entered to bat in his final Test — the crowd at The Oval gave him a standing ovation. England's Eric Hollies (a leg-spinner) bowled him second ball for a duck (0 runs). Bradman later said he was moved to tears by the reception and could not see the ball clearly. His final average settled at 99.94 (6,996 runs / 70 dismissals). The story of the final duck dropping his average from 100 to 99.94 is one of cricket's most poignant moments.
