How this calculator works
Strike rate divides runs by balls and multiplies by 100, so it reports runs per hundred balls. A batter who scores 50 from 30 balls has a strike rate of 166.67. Balls faced include dot balls and balls on which the batter scores no run, but not wides or no-balls, which are not counted against the batter. Strike rate and batting average answer different questions: average measures how long a batter lasts per dismissal, while strike rate measures how quickly they score. A useful comparison uses both, because a very high strike rate with a low average can mean brief but aggressive innings.
Formula
Strike rate = runs scored / balls faced x 100. Rearranged: runs = strike rate x balls / 100; balls = runs x 100 / strike rate.
Worked example
Fifty runs from 30 balls gives 50 / 30 x 100 = 166.67. Seventy-five runs from 60 balls gives 75 / 60 x 100 = 125.00. To score 200 runs at a strike rate of 160, a batter needs 200 x 100 / 160 = 125 balls.

Frequently asked questions
Why is strike rate per 100 balls rather than a percentage?
The scale makes the number easy to read. A strike rate of 100 means one run per ball, and 150 means 1.5 runs per ball, which is clearer than 1.5 as a fraction.
Do wides count against the batter?
No. A wide is charged to the bowler and does not count as a ball faced. A no-ball is also not counted as a ball faced by the batter, although runs scored off it can be credited to the batter.
What strike rate is good?
It depends on the format. T20 innings commonly run above 130, one-day innings historically around 85 to 95, and Test innings often below 60. Compare players in the same format and era.
