Net run rate (NRR) calculator

Free net run rate (NRR) calculator for cricket: enter runs and overs for each match to get a team NRR, plus an overs to balls converter.

Net run rate, usually shortened to NRR, decides who goes through when teams finish level on points in a league or a tournament group. It measures how fast a team scores compared with how fast it lets the opposition score.

The formula is simple: NRR = (total runs scored divided by total overs faced) minus (total runs conceded divided by total overs bowled). The totals are taken over every match the team has played, not match by match. A positive number means the team scores faster than it concedes; a negative number means the opposite.

Overs are counted the cricket way. 17.4 overs is 17 overs and 4 balls, which the calculator turns into 17.667 overs before dividing. If a team is bowled out before using its overs, its full quota (20 in a T20, 50 in a one-day match) is used as the overs faced. If a match is shortened by rain, the overs the innings was allowed are used, and abandoned matches do not count.

To use the calculator, enter the runs scored, overs faced, runs conceded and overs bowled for each match, and press Add a match for more rows. The result updates as you type. To see what a coming match would do to a team's NRR, add a row with the score you expect.

How many balls are in an over? Six legal balls. Wides and no-balls are extra deliveries and do not count towards the six. So 20 overs is 120 balls, 50 overs is 300 balls, and 17.4 overs is 106 balls. The small overs to balls tool above does that sum for you.

Why does NRR matter? In many events, including ICC World Cup groups, the Asia Cup, the IPL, the PSL and the WBBL, two teams can end on the same points. NRR is the first tie-breaker, so a big win can lift a team above a rival even when the points are equal, and a heavy defeat can cost a place in the knockouts.

A few worked numbers help. A team that scores 180 in 20 overs and concedes 150 in 20 overs has a run rate of 9.00 and an opposition rate of 7.50, so its NRR is +1.500 for that match. A team that chases 150 in 15 overs and wins has scored at 10.00 per over and conceded at 7.50 if it bowled the full 20, giving +2.500, which is why chasing quickly helps as much as winning.

The same method works for any competition that publishes its tables with NRR. The ICC rules for each event say whether a super over, a rain reduction or a forfeit changes the calculation, so check the playing conditions of your tournament if the table looks different from the calculator.
