Batting Strike Rate Calculator
Calculate runs per 100 balls faced — T20, ODI & Test
Enter the runs and balls faced from one batter's scorecard row. The result expresses their scoring pace per 100 balls, whether they faced six balls or sixty. This tool calculates from your entries; it does not fetch a live score.
Use the batter's runs, excluding team extras.
Copy the recorded balls faced (BF), not the team's overs.
The rate is rounded to two decimal places. Labels such as “Explosive” use fixed thresholds; they do not account for the format, pitch, opposition or match situation.
Enter the runs credited to the batter, without the team's extras.
Enter the recorded balls faced as a whole number greater than zero.

Formula: (Runs Scored ÷ Balls Faced) × 100
Example: 87 runs off 54 balls = 161.11 strike rate
What batting strike rate actually measures
A score of 87 tells you how many runs a batter contributed. Add “from 54 balls” and you can see the pace of that contribution. Strike rate puts that pace on a common scale so innings of different lengths can be compared.
Batting strike rate = (batter's runs ÷ balls faced) × 100
Check 87 runs from 54 balls
- Divide 87 by 54: 1.611111… runs per ball.
- Multiply by 100: 161.111111… runs per 100 balls.
- Round the final answer: 161.11.
That does not mean the batter scored 161 runs or faced 100 balls. It means their scoring pace was equivalent to about 161 runs per 100 balls. It is a rate, not a percentage of deliveries on which they scored.
For a quick sense check, one run per ball is a strike rate of 100. Two runs per ball is 200. A score of 15 from 20 balls gives 75.00. There is no requirement to reach a minimum innings length before calculating it, but a short innings gives you less evidence about a player's usual pace.
Balls faced and balls in the over are different counts
Use the batter's recorded BF figure. In standard scoring, no-balls count towards balls faced, while wides do not. Neither counts as a legal ball in the over. That distinction is why “legal deliveries faced” is an unreliable substitute for the strike-rate denominator.
The NSW Cricket Umpires’ and Scorers’ Association scoring manual, page 47, explains the balls-faced convention. Modified competitions can use different scoring settings, so use their official record when checking a result.
| Delivery | Batter runs added | Balls faced added | Legal balls added |
|---|---|---|---|
| Legal dot ball | 0 | 1 | 1 |
| Legal delivery, four off the bat | 4 | 1 | 1 |
| Legal delivery, two leg-byes | 0 | 1 | 1 |
| Wide | 0 | 0 | 0 |
| No-ball hit for four | 4 | 1 | 0 |
A four struck from a no-ball adds four to the batter and a separate no-ball penalty to extras. Enter the batter's four, not the full five added to the team. Byes, leg-byes and wides are also outside the batter's run total.
Do not subtract no-balls from an existing BF entry or add them again: they should already be accounted for. If the scorecard does not provide balls faced, runs and team overs alone are not enough to reconstruct the individual figure.
Watch the rate change during an innings
Imagine a batter on 20 from 14 balls. They next face a dot, hit a four, then hit a six, all from legal deliveries. Recalculate from the updated totals each time.
| Situation | Runs | Balls faced | Strike rate |
|---|---|---|---|
| Starting score | 20 | 14 | 142.86 |
| After the dot | 20 | 15 | 133.33 |
| After the four | 24 | 16 | 150.00 |
| After the six | 30 | 17 | 176.47 |
The dot lowers the rate because the ball count rises without any runs. The boundaries reverse that change. A large swing over three balls is possible in a short innings; the same sequence has a smaller effect after a batter has faced many more balls.
The final rate can hide an acceleration
Suppose a batter starts with 18 from 20 balls, then adds 30 from the next 16. Their first passage has a rate of 90.00, their second 187.50, and the full 48 from 36 gives 133.33. Reporting only the final rate misses how the innings changed.
To check the second passage, subtract both earlier totals: 48 − 18 runs and 36 − 20 balls. Enter 30 and 16 in the calculator. Use the same start and end points for both numbers.
Work backwards from a target rate
At 36 from 30 balls, a batter's rate is 120. To reach 140 after another ten balls faced, they need a total of 140 × 40 ÷ 100 = 56 runs: 20 more from ten. This is a personal scoring target, not the team's required run rate. For the team's chase, use the run-rate calculator.
Combine innings by adding runs and balls first
For a season or a series, keep the same set of innings in both totals. A batter who scores 29 from 20 balls and 70 not out from 60 has made 99 from 80. Enter those combined figures to get 123.75.
The individual rates are 145.00 and 116.67. Their simple average, 130.835 using the displayed values, is not the combined rate: it gives the short innings as much weight as the long one. Adding raw totals naturally gives each ball the same weight.
Not out affects average, not strike rate
If the batter was dismissed in the 29-run innings and not in the 70-run innings, their batting average across the two is 99 ÷ 1 dismissal = 99.00. Their strike rate is still 99 ÷ 80 × 100 = 123.75. The asterisk beside 70 changes neither the runs nor the balls used here.
When comparing players, keep formats and competitions separate where possible. A career figure that mixes different roles and match formats can conceal more than it explains. Also leave out any innings whose balls-faced figure is missing; do not add its runs to a total with an incomplete denominator.
Is the strike rate good for this innings?
Start with the job the batter had to do. A late cameo in a T20 chase, an ODI innings after early wickets and a Test innings on a difficult pitch should not be judged against one universal threshold.
- Check the size of the contribution. Twelve from six and 60 from 30 both produce 200.00. The second innings provides five times as many runs at the same pace.
- Check the stage of the match. A rate of 120 may be enough while completing a small chase. It may leave too much work for a partner when the required team rate is climbing.
- Check conditions and role. Compare innings with similar pitches, bowling, field restrictions and batting positions before drawing a conclusion about a player.
This calculator takes only runs and balls. It cannot measure shot quality, difficulty, boundary percentage, dot-ball percentage or win probability. Two batters can reach the same rate with quite different combinations of singles and boundaries.
The result's descriptive rating is a fixed numerical label, not a format-specific assessment. Read the number together with the scorecard. For an example that separates batting runs from team extras, see the homepage scorebook walkthrough.
Before changing an unexpected result
Check the two inputs against the same batter and the same stage of the innings. These answers cover the most common points of confusion.
Do I type 8.3 overs into Balls Faced?
No. This field takes a whole-number count for the individual batter. The team’s 8.3 overs means 51 legal deliveries across the innings, shared between batters; it does not tell you how many this batter faced. Copy their BF figure instead.
Can strike rate be calculated with zero balls faced?
No. Dividing by zero leaves the rate undefined, so this calculator requires at least one ball faced. Zero runs from a positive number of balls is valid and produces 0.00. Do not replace a missing ball count with zero.
Do I include extras in Runs Scored?
Use only the runs credited to the batter. A four off a no-ball contributes four to that input; the no-ball penalty belongs to extras. Wides, byes and leg-byes also stay outside the batter’s run total.
Should I remove no-balls from the scorecard’s BF figure?
No. Standard scoring counts no-balls in balls faced even though they do not count towards the over’s legal deliveries. Use the recorded BF total without subtracting them. For a modified competition, follow its official scoring convention.
Does being not out improve strike rate?
Not by itself. A batter on 45 from 30 balls has a strike rate of 150.00 whether out or not out. Dismissals are needed for batting average, but this calculator only uses runs and balls faced.
Why is the displayed result rounded?
Some divisions do not end neatly. For 25 from 18 balls, the rate is 138.888… and the display rounds it to 138.89. Runs per ball is shown separately to three decimal places. When combining innings, use the original runs and balls rather than either rounded value.
Does a strike rate above 100 mean a percentage error?
No. Strike rate expresses runs per 100 balls, so it can exceed 100. Nine runs from six balls gives 150.00. It does not mean the batter scored on 150% of deliveries.
Can I use the tool for a series or part of an innings?
Yes. For a series, add runs and balls from the same set of innings before entering the totals. For one passage of play, subtract the opening runs and balls from the closing figures. Keep the time window consistent for both inputs.
