nRR

Net Run Rate (NRR) is a metric used in cricket standings to compare teams with equal points in limited-overs competitions. It measures how effectively a team scores runs relative to how many runs it concedes, averaged across all matches in the competition.

Calculation: For a team, NRR = (total runs scored by the team / total overs faced) − (total runs scored against the team / total overs bowled). Overs are counted as completed overs plus balls; for example, 12.4 overs means 12 overs and 4 balls, which equals 12 + 4/6 = 12.667 overs. The calculation uses actual figures from each match, not a fixed innings length. A positive NRR means the team scores at a higher rate than it concedes on average; a negative NRR means the opposite.

Example: If Team A scores 240 in 50 overs and concedes 210 in 46 overs, their run rate is 4.80 (240/50) and the opponents’ run rate is about 4.57 (210/46). The NRR would be approximately +0.23.

Application and tie-breaking: In group stages of One Day Internationals and Twenty20 competitions, teams are typically ranked by points, with NRR as the primary tiebreaker when points are equal. If teams still cannot be separated by NRR, other tie-breakers defined by the competition rules (such as head-to-head results) are used.

Notes: NRR can be influenced by both large-margin wins and heavy defeats, and is computed across all completed matches in the pool or season. It is not generally used in Test cricket, which uses a different ranking framework.
