Net Run Rate Rules and Calculations

NRR

Run rate = Total no of runs scored / Total no of overs faced

Net Run Rate Rules – For a single match

The net run rate in a single game is nothing but the run rate per over that a team scores minus the run rate per over that is scored against them.

Net run rate is the statistical calculation which is used in the game of cricket, infact most commonly used in limited over cricket format league competitions.

Based on the good net run rate the teams which are in the top of the league table will be qualified for next level may be finals or semi finals. It means the NRR of these teams are compared when certain situations arise.

Net run rate = (Total no of runs scored / Total no of overs faced) – (Total no of runs conceded / Total no of overs bowled).
Net run rate for a T-20 Cricket series competition.
Let’s say there are four teams Team A, Team B, Team C and Team D

Note:
E.g.

1) The 15.2 overs of cricket terminology is calculated as 15+2/6, 15+1/3 infact 15.333 mathematically.
2) The 15.5 overs of cricket terminology is calculated as 15+5/6, 15+0.833 infact 15.8333 mathematically.

Check out the different cases shown below based on different situations.

(Match 1)
Match between Team A and Team B
Let’s say Team A scores 150/5 in 20 overs and Team B scores 140/4 in 20 overs and loses the match.

Net run rate for Team A = 150/20-140/20 = 7.5-7.0 = 0.5

Net run rate for Team B = 140/20-150/20 = 7.0-7.5 = -0.5

Right now league Table for these four teams would be in this way.

Teams Played NRR
A 1 0.5
B 1 -0.5
C 0 0.0
D 0 0.0

(Match 2)

Match between Team B and Team C
Let’s say Team B scores 139/5 in 20 overs and Team C scores 140/4 and wins the game in 18.2 overs. (18.2 overs = 18+2/6 overs = 18+1/3 overs = 18.33 mathematically)

New Net run rate for Team B = (140+139/20+20)-(150+140/20+18.33) = 6.975-7.5658 = -0.5908

Net run rate for Team C = 140/18.33-139/20 = 7.637-6.95 = 0.687

Right now league Table for these four teams would be in this way.

Teams Played NRR
A 1 0.5
B 2 -0.5908
C 1 0.687
D 0 0.0

(Match 3)

Match between Team A and Team C
Let’s say Team A scores 150/5 in 20 overs and Team C scores 130/10 (all out) in 18 overs and loses the match.

Note: when ever any team gets all out then the total no of overs faced will be equal to full quota of overs and also the opposite team gets the credit of full quota of overs bowled.

Since Team C has been bowled out, Team A gets the credit of full quota of 20 overs bowled instead of 18 overs actually bowled, and Team C gets the full quota of 20 overs faced instead of 18 overs actually faced.

Therefore

New Net run rate for Team A = (150+150/20+20)-(140+130/20+20) = 7.5-6.75 = 0.75

New Net run rate for Team C = (140+130/18.33+20)-(139+150/20+20) = 7.044-7.225 = -0.181

Right now league Table for these four teams would be in this way.

Teams Played NRR
A 2 0.75
B 2 -0.5908
C 2 0.687
D 0 0.0

(Match 4)

Match between Team A and Team D
Let’s say Team A scores 149/10 (all out) in 16 overs and Team D scores 150/6 in 18 overs and wins the match.

Note: when ever any team gets all out then the total no of overs faced will be equal to full quota of overs and also the opposite team gets the credit of full quota of overs bowled.

New Net run rate for Team A = (150+150+149/20+20+20)-(140+130+150/20+20+18) = 7.4833-7.241 = 0.2423

Net run rate for Team D = 150/18-149/20 = 8.333-7.45 = 0.883

Right now league Table for these four teams would be in this way.

Teams Played NRR
A 3 0.2423
B 2 -0.5908
C 2 0.687
D 1 0.883

(Match 5)

Match between Team B and Team D

Let’s say Team B scores 140/10 (all out) in 18 overs and Team D scores 130/10 (all out) in 16 overs and loses the match.

Note: when ever both teams get all out then the total no of overs faced and total no of overs bowled will be equal to full quota of overs for both of the teams in the overs column.

New Net run rate for Team B = (140+139+140/20+20+20)-(150+140+130/20+18.33+20) = 6.983-7.200 = -0.217

New Net run rate for Team D = (150+130/18+20)-(149+140/20+20) = 7.368-7.225 = 0.143

Right now league Table for these four teams would be in this way.

Teams Played NRR
A 3 0.2423
B 3 -0.217
C 2 0.687
D 2 0.143

(Match 6)

Match between Team C and Team D
Let’s say Team C scores 130/8 in 20 overs and Team D scores 130/10 (all out) in 19.4 overs and ties the match.

New Net run rate for Team C = (140+130+130/18.33+20+20)-(139+150+130/20+20+20) = 6.857-6.9833 = -0.126

New Net run rate for Team D = (150+130+130/18+20+20)-(149+140+130/20+20+20) = 7.068-6.983 = 0.085

Finally league Table for these four teams would be in this way.

Teams Played NRR
A 3 0.2423
B 3 -0.217
C 3 -0.126
D 3 0.085

At the end of the day this is what the whole Net run rate is all about is.
