Net Run Rate (NRR) = (Total runs scored by a team / Total overs faced by that team) – (Total runs conceded by a team / Total overs bowled by that team)
Use only completed overs in the calculation
If a team is all out before using all its overs, count the full quota of overs for that innings
If a team wins while chasing and reaches the target in fewer overs, count only the overs actually faced
In rain-affected matches, use the official match rules for revised overs and targets
Calculate batting run rate first
Calculate bowling run rate second
Subtract bowling run rate from batting run rate to get NRR
NRR can be positive or negative
For tournament NRR, add all matches played by the team before applying the formula
