What this calculator does
Turn the numbers on a cricket scorecard into the rates fans and selectors use to judge players. A batter's strike rate shows how fast they score, in runs per 100 balls. Their average shows how many runs they make, on average, before getting out. A bowler's economy rate shows how many runs they give away per over (a set of six balls). Their bowling average and strike rate show how many runs and how many balls each wicket costs.
This calculator works out all five from the numbers on a scorecard. Choose batting or bowling, then enter the totals for a match, a season or a career. You'll see the figures with the working shown. Overs are read in cricket notation, so 412.3 means 412 overs and 3 balls.
Where it's used
Why this math matters outside the classroom:
- Short-format selection. A coach compares a batter striking at 125 (50 off 40 balls) with one at 90 when picking a side for a 20-over game.
- Bowling spells. A captain sees that 28 runs off 4 overs is an economy of 7 and keeps a tighter bowler on for the final overs.
- Season reviews. Club scorers divide each bowler's runs conceded by wickets, such as 1,890 ÷ 64 = 29.53, for the end-of-season averages.
- Rates per 100. Students see that a strike rate is a rate per 100: 45 runs off 60 balls is 45 ÷ 60 × 100 = 75.
- Fantasy cricket. Players compare economy rates and strike rates to choose bowlers and batters for a weekend's matches.

How to use it
- Choose batting or bowling figures.
- For batting, enter runs scored, balls faced, innings batted and the number of not outs.
- For bowling, enter runs given away, overs bowled in cricket notation and wickets taken.
- Read the headline rate, then the average and the other figures underneath.
What the inputs mean
- Balls faced
- Balls the batter faced. Wides don't count as balls faced; no-balls do.
- Not outs
- A not out is an innings where the batter was still in at the end. That happens when the team was all out with them unbeaten, the overs ran out or the target was reached. Not outs don't count as dismissals, so they raise the average.
- Runs conceded
- Runs scored off the bowler's deliveries, as on a standard scorecard. That includes wides and no-balls but not byes or leg byes.
- Overs bowled
- Overs are written as completed overs, a point, then the extra balls, from 0 to 5. So 412.3 overs is 412 × 6 + 3 = 2,475 balls, or 412.5 true overs.
Formula and method
batting strike rate = runs ÷ balls faced × 100 batting average = runs ÷ (innings − not outs) economy rate = runs conceded ÷ overs bowled bowling average = runs conceded ÷ wickets bowling strike rate = balls bowled ÷ wickets
Strike rate is a rate per 100 balls. So a batter who scores 50 off 40 balls has a strike rate of 125. Batting average divides runs by the number of times the batter got out, which is innings minus not outs. A batter who has never been out has no average yet.
For bowlers, lower is better on all three figures. "Runs conceded" means runs given away. Economy uses true overs, so the balls part of 412.3 is first turned into a fraction of an over (3 ÷ 6 = 0.5). Bowling average and strike rate both divide by wickets. So they can't be worked out until the bowler has taken one.
Worked example
An invented batter, Dev Arkwright, has scored 1,520 runs off 1,680 balls in 42 innings, and 6 of them were not out. An invented bowler, Sam Okafor, has given away 1,890 runs in 412.3 overs and taken 64 wickets.
- Arkwright's strike rate: 1,520 ÷ 1,680 × 100 = 90.48.
- The times he got out: 42 − 6 = 36. So his average is 1,520 ÷ 36 = 42.22.
- Okafor's overs: 412.3 is 2,475 balls, and 2,475 ÷ 6 = 412.5 overs. Economy: 1,890 ÷ 412.5 = 4.58.
- Bowling average: 1,890 ÷ 64 = 29.53. Bowling strike rate: 2,475 ÷ 64 = 38.67 balls per wicket.
Result: Arkwright scores at a strike rate of 90.48 with an average of 42.22. Okafor's economy rate is 4.58, with an average of 29.53 and a strike rate of 38.67.
Understanding the result
What counts as good depends on the format. In longer matches, batters value a high average and bowlers a low average. In short formats, a high batting strike rate and a low economy rate matter more.
Averages from a few innings or wickets move a lot with each new game. A season or career total gives a steadier picture than one match.
Assumptions and limitations
- Six-ball overs.
- Runs conceded follow standard scorecard practice: byes and leg byes are not charged to the bowler.
- The figures you enter come from the same set of matches.
- These rates describe what happened. They don't adjust for pitch conditions, how strong the other team was or the match situation.
- Batting average can't be worked out until the first dismissal. Bowling average and strike rate can't be worked out until the first wicket.
- Older records with eight-ball overs need the overs turned into balls by hand.
Frequently asked questions
What is the difference between strike rate and average for a batter?
Strike rate measures speed: runs per 100 balls faced. Average measures consistency: runs per dismissal. A batter can score quickly but get out often, with a high strike rate and a lower average. Or they can score slowly but reliably, with a lower strike rate and a high average.
Why do not outs raise a batting average?
The average divides runs by dismissals, not innings. Runs from a not-out innings are added to the total. But there is no extra dismissal to divide by, so the average rises.
Is bowling strike rate the same as economy rate?
No. Economy is runs given away per over, and bowling strike rate is balls bowled per wicket. A bowler can be economical but rarely take wickets. Or they can take wickets often but give away a lot of runs.
Why does 4.3 overs count as 4.5 overs?
Because the 3 after the point means three balls of a six-ball over, and 3 ÷ 6 = 0.5. Using 4.3 directly would make the overs look too small and the economy rate too high.
How this calculator is checked
Method: Standard cricket statistics definitions: batting strike rate (runs per 100 balls), batting average (runs per dismissal), economy rate (runs per over), bowling average (runs per wicket) and bowling strike rate (balls per wicket), with six-ball overs. The calculation is covered by automated tests with known reference values and edge cases. Last updated 2026-10-18. Found a problem? Tell us.
