Enter a bowler’s overs, runs conceded and wickets to get the three key bowling numbers: economy rate, bowling average and strike rate. Add dot balls for the dot-ball percentage. Overs use normal cricket notation, like 23.4.

The formulas
- Economy = runs conceded ÷ overs bowled (runs per over)
- Average = runs conceded ÷ wickets (runs per wicket)
- Strike rate = balls bowled ÷ wickets (balls per wicket)
For all three, lower is better.
Worked example
A bowler sends down 23.4 overs (142 balls), concedes 180 runs and takes 9 wickets, with 60 dot balls.
- Economy = 180 ÷ 23.667 = 7.61
- Average = 180 ÷ 9 = 20.00
- Strike rate = 142 ÷ 9 = 15.78 balls per wicket
- Dot-ball % = 60 ÷ 142 = 42.25%
A common mistake is dividing by 23.4 instead of 23.667. That would give an economy of 7.69 instead of 7.61.
Frequently asked questions
What is a good economy rate in T20?
It depends on the league and the phase of the innings. Across T20 cricket, under 8 an over is generally considered good, and under 7 is excellent. Death-over specialists often go at more.
Do wides and no-balls count?
Runs from wides and no-balls count against the bowler. Those deliveries are not counted as legal balls, so they don’t add to overs.
