A bowling economy rate tells you how hard a bowler is to score against. It is the average number of runs the bowler concedes per over. A low economy rate means tight, controlled bowling. A high economy rate means the batters are scoring freely. For captains and coaches, economy is often the first number they check.
This free calculator works out three bowling numbers at once: economy rate, bowling average, and bowling strike rate. Enter runs conceded, wickets taken, and balls bowled. The tool shows all three results instantly, with no sign-up and no download. Everything runs in your browser.
The economy formula is simple. Divide runs conceded by overs bowled. Overs bowled means balls bowled divided by six. For example, a bowler who concedes 45 runs from 60 balls has bowled 10 overs, so the economy rate is 4.50. A bowler who concedes 30 runs from 24 balls has bowled 4 overs, so the economy rate is 7.50.
Bowling average is a different measure. It is runs conceded divided by wickets taken. It answers the question: how many runs does this bowler give away for each wicket? A bowler with 45 runs and 3 wickets has an average of 15.00. Lower is better. Bowling strike rate is balls bowled divided by wickets taken: it shows how many balls the bowler needs, on average, to take a wicket. Here that is 20.00.
Economy matters most in short formats. In T20 cricket, a bowler who concedes under 7 runs per over is doing well, and under 6 is excellent. In one-day cricket, an economy under 5 is strong. In test cricket, economy matters less than wicket-taking, but a bowler who holds one end tight still helps the team by building pressure from the other end.
To use the tool, enter the runs the bowler conceded, including all runs scored off their bowling. Enter the wickets they took. Enter the balls they bowled, not the overs: 60 balls is 10 overs, 54 balls is 9 overs, and 63 balls is 10 overs and 3 balls. If you only know the overs, multiply full overs by six and add the remaining balls. Then press calculate.
How do you read the three numbers together? A bowler with a low economy and a low average is a star: hard to score against and takes wickets. A bowler with a low economy but a high average is a container: they stop runs but rarely strike. A bowler with a high economy but a low average is a wicket-taker who leaks runs. Teams need all three types at different moments.
Common mistakes are easy to avoid. First, do not enter overs where the tool asks for balls: entering 10 instead of 60 gives a nonsense economy. Second, count wides and no-balls in the runs conceded, because the bowling team really did give those runs away. Third, remember that a bowler with no wickets has no average and no strike rate: the tool shows a dash for those two numbers, which is correct, not an error.
Coaches use these numbers to plan spells. A bowler with a great economy bowls at the death, when batters attack hardest. A bowler with a great strike rate bowls when the team needs a breakthrough. Tracking these numbers across a season shows real progress better than memory does: memory remembers the great days and forgets the bad ones.
Young bowlers often ask how to improve economy. The honest answer is line and length before tricks: bowl at the stumps, make the batter play, and cut out the loose ball each over. Use this calculator after every match to build a true record of your bowling. Over a season, the numbers will tell you which plans work and which ones only feel good.
