Economy Rate Calculator

Divide the runs conceded by the overs bowled. Thirty-eight runs from ten overs is an economy rate of 3.80. If the spell ended mid-over, convert to balls first: 9.3 overs is 57 balls, which is 9.5 decimal overs, so 38 runs is an economy of exactly 4.00.

Convert the overs into balls, then divide the balls by six. The figure after the decimal point in cricket notation is a ball count, not a fraction, so 9.3 overs means 57 balls and divides as 9.5 rather than 9.3.

No. Byes and leg byes go to the team total but are not charged to the bowler. Wides and no-balls are charged to the bowler, along with every run scored off the bat from their deliveries.

Under eight runs an over across a full four-over spell is respectable and under seven is very good. The figure has to be read with the phase in mind, because bowling at the death is far more expensive than bowling inside the powerplay.

Economy rate belongs to a bowler and counts the runs they personally concede per over. Run rate belongs to the innings and counts every run the batting side scores per over, including byes and leg byes that no bowler is charged with.

Around five an over across a full ten-over spell is competitive and under four and a half is very good, though the figure moves with the era and the conditions. A bowler operating entirely inside the powerplay and one bowling at the death are being asked to do different jobs at very different prices.

Zero, yes — a bowler who concedes nothing in a maiden has an economy of 0.00 for that over. Negative is impossible, because runs cannot be taken off a total. A bowler dismissing a batter off a wide still concedes that wide, so even a wicket-taking over has a floor of zero.

It pulls it down sharply, especially early in a spell. A bowler who has conceded 12 from two overs is going at six; a maiden takes the same 12 runs over three overs and the rate falls to four. The effect shrinks as the spell lengthens, which is why maidens are most valuable to a figure early on.

Almost always the part over. A scorecard showing 9.3 overs means 57 balls, which divides as 9.5, not 9.3. The other common cause is byes and leg byes — those appear in the team total but are not charged to any bowler, so adding the team's extras into a bowler's figure inflates it.
