What is Net Run Rate (NRR) Difference?
In cricket tournaments, Net Run Rate (NRR) is the primary tie-breaker when teams are level on points. The NRR difference determines how far ahead or behind one team is compared to another. This calculator helps you analyze the margin by which a team is leading or trailing in the statistical standings.
The NRR Formula
The standard formula used by the ICC and major leagues like the IPL is:
NRR = (Total Runs Scored / Total Overs Faced) – (Total Runs Conceded / Total Overs Bowled)
Important Rules for Calculation
- All Out: If a team is bowled out before completing their full quota of overs (e.g., all out in 18.2 overs in a 20-over match), the calculation uses the full quota of overs (20.0) for the "Overs Faced" variable.
- Overs Notation: Cricket overs are entered in decimal format where .1, .2, .3, .4, and .5 represent the number of balls. Our calculator automatically converts these (e.g., 20.3 overs becomes 20.5 decimal overs) for precision.
- Rain Affected Matches: In DLS-affected matches, the revised targets and revised overs are used for calculation purposes.
Example Calculation
Suppose Team A has scored 800 runs in 100 overs and conceded 750 runs in 100 overs.
- Team A Runs per Over Scored: 800 / 100 = 8.00
- Team A Runs per Over Conceded: 750 / 100 = 7.50
- Team A NRR: 8.00 – 7.50 = +0.500
If Team B has an NRR of +0.200, the NRR Difference is 0.300 in favor of Team A.
