What is the formula to calculate economy rate of a bowler ?

Question

How to calculate economy rate of a bowler in cricket ?

Answer 1

how many runs he concedes on average per over

so basicly the number of runs hes conceded divided by the number of overs hes bowled

Answer 2

How many runs he usually givs.

Answer 3

economy rate is the run conceded per over

in 9 overs you conceded 45 runs economy rate is

=45/9= 5.0

what if in 9.1 overs you conceded 45 runs??

= 45/9.1 will not work as there are only 6 balls (& not 10) in an over

try this (9 overs x 6 balls)+1 = 55 balls

=(45/55)*6= 4.909
