How this calculation works
Bowling average, strike rate and economy use different denominators. Average asks how many charged runs accompany a wicket, strike rate how many legal balls accompany it, and economy how quickly runs are conceded per six-ball over.
Bowling average = total charged runs/credited wickets; strike rate = total legal balls/credited wickets; economy = total charged runs × 6/total legal ballsA worked example
The first spell’s 3.4 overs are twenty-two legal balls. The second has twenty-four, so total deliveries are forty-six, not 7.4 decimal overs. With fifty-one charged runs and three credited wickets, average is seventeen runs per wicket and strike rate about 15.333 balls per wicket. Aggregate economy is about 6.65217 runs per over.

What this calculation answers
Bowling average, strike rate and economy use different denominators. Average asks how many charged runs accompany a wicket, strike rate how many legal balls accompany it, and economy how quickly runs are conceded per six-ball over.
This page aggregates the underlying scorebook totals before taking ratios. Averaging individual spell ratios can distort the result when spells have different lengths or wicket counts.
The Cricket aggregate net run rate calculator compares team scoring and conceding rates with all-out quota rules. Individual bowling statistics instead use actual credited balls, runs and wickets.
Use the right input conventions
Enter legal deliveries using overs.balls notation. A final digit of four means four balls, not four-tenths of an over. Wides and no-balls do not automatically add a legal ball merely because a delivery occurred.
Runs must be the amount actually charged to the bowler, and wickets must be credited to that bowler. The site does not infer how team extras or dismissals should be assigned under scoring laws.
Interpret the result
A bowler with no credited wickets has undefined average and strike rate, even if legal deliveries and charged runs are known. The economy calculation can still be defined, so the page preserves it instead of replacing every metric with zero.
These ratios summarize the entered figures; they do not rank a player across formats, adjust for conditions or predict future performance. Lower or higher values can have different practical meaning depending on role and match context.
Work through the example
The first spell’s 3.4 overs are twenty-two legal balls. The second has twenty-four, so total deliveries are forty-six, not 7.4 decimal overs.
With fifty-one charged runs and three credited wickets, average is seventeen runs per wicket and strike rate about 15.333 balls per wicket. Aggregate economy is about 6.65217 runs per over.
Where the model stops

Confirm charged runs and credited dismissals from a reliable scorebook. Team totals are not a substitute for a bowler’s figures.
A few questions, answered
Why is average undefined with no wickets?
Its denominator is credited wickets, so zero wickets cannot produce a finite runs-per-wicket average.
Can I average my spell economy values?
Not without weighting by legal balls. Aggregate charged runs and total legal balls give the correct overall rate.
