Net Run Rate has often been a misunderstood concept although it’s a straightforward calculation.

NRR(Net Run Rate) as the name suggests is the difference of average runs scored per over and average runs scored against them per over.

There are certain restriction on match type that can be used for NRR calculation

• Match should have a result
• In the case of Duckworth/Lewis/Stern has been used to decide the winner, for net run rate purposes Team 1 will be credited with Team 2’s Par Score on abandonment off the same number of overs faced by Team 2
• If the DL method is applied in the earlier part of the match also Team 1 will be credited with 1 run less than the final Target Score for Team 2 off the total number of overs allocated to Team 2 to reach the target.
• If a team is all out then its full allocated quota of overs will be used for calculation.

Consider events where Team 1 has played four matches in the T20 competition

Team 1 scores

• 120 all out
• 165/7 in 20 overs
• 175/4 in 16.3 overs

Team 1 was all out in the first match so the entire 20 overs will be used in the calculation. Total overs played by Team 1 will be 20 + 20 + 16.3 = 56.3 overs and scored 120 + 165 + 175 = 460 runs.

56.3 overs = 339 balls

Therefore Team 1 : For Run Rate = 460/339*6 = 8.14159

Scores against Team 1

• 123 in 13.4 overs
• 156 all out
• 171 in 20 overs

Team 1 bowled out the opponent in the second match so while calculating run rate we will take into account as if opponent has batted the entire allocated 20 overs. Team 1 bowled 13.4 + 20 + 20 = 53.4 overs and gave away 123 + 156 + 171 = 450 runs

53.4 overs = 322 balls

Therefore Team 1 : Against Run Rate = 450/322*6 = 8.38509

The net run-rate is, difference of For Run Rate and Against Run Rate

  For Run Rate :    8.14159
  Against Run Rate: 8.38509
