Cricket Batting & Bowling Average Calculator

All five figures are standing definitions published by ESPNcricinfo's Statsguru and consistent with the MCC Laws of Cricket. There are no rates or brackets to go stale — only arithmetic — but two steps trip people up, so the calculator handles both explicitly.

Batting. A batting average is total runs divided by the number of times you were dismissed, not the number of innings you batted:

• Dismissals = innings − not-outs
• Batting average = runs ÷ dismissals
• Batting strike rate = (runs ÷ balls faced) × 100

Not-out innings still add their runs to your total, but they are removed from the denominator because you were never out. That is why leaving them in — dividing by all innings — understates a real average. If dismissals reach zero (out in none of your innings), the average is undefined; the tool shows "—" rather than a misleading number.

Bowling.The catch here is over notation. Overs are counted in base 6, so "12.3 overs" means 12 completed overs plus 3 balls, not 12.3 decimal overs. The tool converts first, then divides:

• Balls = whole overs × 6 + balls-in-over
• True overs = balls ÷ 6
• Bowling average = runs conceded ÷ wickets
• Economy rate = runs conceded ÷ true overs
• Bowling strike rate = balls ÷ wickets

Because an over is six balls (MCC Law 17), the balls-in-over part must be 0–5; the tool rejects things like "12.6" and tells you to write 13 instead. As a built-in consistency check the three bowling numbers satisfy the identity economy = 6 × average ÷ strike rate, so they can never silently disagree. Everything runs in your browser — nothing is uploaded. This tool pairs with the cricket net run rate calculator and the Duckworth-Lewis-Stern calculator for team-level and rain-rule maths.
