Net run rate, or NRR, is the number that decides who goes through when teams finish level on points. It measures how quickly a team scores compared with how quickly it concedes, across a whole tournament.
The net run rate formula
Net run rate compares how fast a team scores with how fast its opponents score against it. Both sides of the comparison are measured in runs per over, and they are added up over the whole tournament instead of match by match.
A positive number means a team has, on average, scored faster than it has conceded. A negative number means the opposite. Zero means the two rates are level.
Reading overs correctly
Overs are not decimals in the usual sense. A completed over is six balls, so 4.3 overs means four overs and three balls, which is 4.5 overs in the calculation. Convert balls by dividing by six before you divide runs by overs.
A worked example, step by step
The numbers below are invented to show the method. They are not from a real team.
| Match | Runs scored | Overs faced | Runs conceded | Overs bowled |
|---|---|---|---|---|
| Match 1 | 180 | 20.0 | 160 | 20.0 |
| Match 2 (chase won with overs to spare) | 140 | 15.0 | 139 | 20.0 |
| Totals | 320 | 35.0 | 299 | 40.0 |
- Rate scored: 320 ÷ 35 = 9.143 runs per over.
- Rate conceded: 299 ÷ 40 = 7.475 runs per over.
- Subtract: 9.143 − 7.475 = +1.668.
Notice what we did not do. Match 1 on its own is +1.000 (9.000 − 8.000) and Match 2 on its own is +2.383, and the simple average of those two is +1.692. That is not the NRR. Because the two matches used different numbers of overs, the totals have to be pooled first and divided afterwards.
Special rules that change the numbers
A team that is all out
If a team is dismissed before using all of its overs, the calculation uses the full quota it was entitled to, not the overs it actually batted. Under ICC tournament rules, as reproduced by ESPNcricinfo, this prevents a collapse from making a score look quicker than it was. For example, a team all out for 120 in 16.2 overs of a 20-over innings is treated as 120 runs from 20 overs, which is 6.00, not 7.35.
A chase that finishes early
When the team batting second reaches its target, it is credited with the overs it actually used. Winning a chase quickly raises that team’s overs-faced figure by less, so the rate is higher. That is why finishing a chase with overs to spare helps NRR.
Rain, DLS and abandoned games
Only matches that produce a result count. A no-result match is left out. Where a match is abandoned but a result is reached under Duckworth-Lewis-Stern, ICC rules credit the first-batting team with the second team’s par score off the same number of overs the second team faced. Where DLS was applied earlier in the match, a further adjustment applies to the target. Always check the tournament’s own playing conditions, because the wording can differ from event to event.
Super overs and forfeits
Runs and overs from a Super Over are not included, according to the ICC clause shown in the T20 World Cup qualifier regulations. In a forfeited match, the runs and overs are not counted for the team awarded the match.
Why net run rate matters
NRR is used to separate teams that finish level on points. It rewards teams that win convincingly, by a large margin of runs or by chasing quickly, and it punishes heavy defeats. That is why teams sometimes push the pace in the last group games even when the result is already decided.
Where NRR sits in the tiebreak order depends on the event. Some tournaments use it straight after points. Others check wins first, as in the 2013 Champions Trophy regulations published on the ESPN table page, where NRR separated teams level on points and wins. Read the tournament’s playing conditions for the order that applies.
For fantasy players, NRR can change team behaviour late in a group stage. A side that needs a big margin may promote hitters, attack with the new ball or chase aggressively. Those role changes can matter more than the headline fixture. Treat this as something to watch for in confirmed lineups, not as a points forecast.
Common mistakes
- Averaging per-match NRRs. Pool runs and overs across all matches instead.
- Using the overs a team was bowled out in. An all-out innings counts as the full quota.
- Treating 4.3 overs as 4.3. Convert balls to a fraction of an over first.
- Counting no-result matches. They are excluded.
- Mixing up NRR with run rate. A run rate describes one innings, while NRR compares scoring and conceding across a tournament.
How to calculate it yourself
- List every match that produced a result.
- Add the team’s runs scored and overs faced, using the full quota for any all-out innings.
- Add the runs conceded and overs bowled, again using the full quota where the opposition was all out.
- Divide runs by overs for each side, converting balls to fractions of an over.
- Subtract the rate conceded from the rate scored.
Frequently asked questions
- Is a positive net run rate good?
- Yes. It means the team has scored faster than it has conceded across the tournament, which is what NRR is designed to reward.
- Does net run rate reset between tournaments?
- Yes. NRR is calculated within a single tournament or stage, using only the matches that count for that table.
- Why does an all-out team get its full overs?
- Otherwise a team could score quickly and lose all its wickets and look better than a team that batted out its overs. The full-quota rule keeps the comparison fair.
- Do abandoned matches count?
- Matches with no result are excluded. If a result is reached under DLS, the tournament rules say how the scores and overs are credited.
- Is net run rate always the first tiebreaker?
- No. The tiebreak order is set by each tournament, so check its playing conditions.
