With some teams likely to end level on points, the Net Run Rate (NRR) could decide who advances to the semifinals of the 2022 T20 World Cup in Australia. Here’s a brief explainer of what NRR is, how it works and what is the formula.
NRR is calculated by subtracting the opposition’s run rate from the other team’s run rate.
Hence, the winning side will have a positive Net Run Rate and the losing team a negative Net Run Rate.
How does the NRR work?
In a tournament, the Net Run Rate is derived by taking the average runs per over scored by that team in each game and subtracting the average runs per over scored against them in each game.
Even if a team is bowled out inside 20 overs, while calculating NRR, it is considered that the team has played its full quota of overs.
What is the NRR formula?
NRR = ((Total runs scored by team)/(Total overs played by team)) - ((Total runs scored against team)/(Total overs played against team))
Step-by-step NRR calculation
India’s NRR is currently +0.730. Below is a breakdown of India’s NRR calculation.
Runs scored by India:
|Opposition||Runs scored||Overs faced|
* India had scored 184 runs in 20 overs but after rain interrupted the match, Bangladesh’s revised target via D/L Method was 151 in 16 overs. Thus, for the purpose of calculating NRR, it is considered that India scored 150 runs in 16 overs.
Runs scored per over by India: 622/76 = 8.18
Runs conceded by India:
|Opposition||Runs conceded||Overs bowled|
Runs conceded per over by India: 564/75.4 = 7.45
India’s Net Run Rate: 8.18 - 7.45 = 0.730.
