Net Run Rate (NRR) compares a team’s scoring rate with the rate at which it concedes runs across the matches counted in a league table. A positive NRR means the team has scored faster per over than its opponents have scored against it; a negative NRR means the reverse.
NRR is often used as a tie-breaker when teams finish level on points, according to the competition’s playing conditions. It does not simply compare a team’s biggest win or a single match: it combines the runs and overs from the relevant matches.
The NRR formula
Each rate is calculated across the matches that count under the competition regulations. This is why NRR must be worked out from the totals, rather than averaging the NRR from individual matches.
Important rule: when a team is all out early
Do not always use the exact over in which a team was dismissed. Under ICC playing conditions, if a team is all out before using its full allocation of overs, its NRR calculation uses the full quota of overs it was entitled to face. For example, in a 20-over match, a team dismissed after 18 overs is normally counted as having used 20 overs for the NRR calculation. Specific competition rules and DLS situations should be checked when they apply.
Worked example: a T20 league
Imagine Team A plays two completed 20-over matches:
| Match | Team A | Opponent | Overs counted for NRR |
|---|---|---|---|
| 1 | 180 in 20 overs | 150 all out in 18 overs | Team A batting: 20; opponent batting: 20 (all out before quota) |
| 2 | 160 in 20 overs | 155 in 20 overs | 20 overs each |
- Total runs scored by Team A: 180 + 160 = 340.
- Total overs faced by Team A: 20 + 20 = 40 overs.
- Total runs conceded: 150 + 155 = 305.
- Total overs used for the opposing innings in NRR: 20 + 20 = 40 overs. The first opponent was all out before its full 20-over allocation, so its full quota counts.
- Team A’s batting rate: 340 ÷ 40 = 8.50 runs per over.
- Team A’s conceded rate: 305 ÷ 40 = 7.625 runs per over.
This simplified example assumes both matches are completed, have no DLS adjustment and count toward the competition NRR. If the match conditions differ, use the applicable tournament regulations.
What can change NRR?
- Scoring quickly: scoring more runs in a given number of overs improves the batting rate.
- Restricting opponents: conceding fewer runs per over improves the bowling rate used in the calculation.
- All-out innings: if an innings ends because the side is all out before its quota, the full quota—not merely the overs used—is counted for NRR under the usual ICC playing-condition rule.
- Rain or revised targets: DLS-affected matches may require special calculations under the competition’s rules, rather than the simple example above.
- No-results and Super Overs: their treatment is defined in the relevant competition regulations; a Super Over is not included in standard NRR calculations under ICC playing conditions.
Common mistakes
- Using the overs actually bowled when a team was all out before its full quota.
- Treating cricket notation such as 19.4 overs as 19.4 decimal overs.
- Averaging match-by-match NRR values instead of calculating from aggregate runs and overs.
- Applying a generic formula to a DLS-affected match without checking the tournament’s playing conditions.
- Assuming NRR alone always decides qualification: competitions may apply other tie-breakers first.
Frequently asked questions
Can a team have a negative NRR and still qualify?
Yes. Qualification depends on the points and tie-break order specified by the competition. A negative NRR does not automatically eliminate a team.
Why does being all out early affect NRR?
The usual ICC rule counts the full quota of overs the side was entitled to face when it is dismissed all out before that quota, preventing the innings from being treated as if it had used fewer overs solely because all wickets fell.
Is 20.3 overs equal to 20.3?
No. It means 20 completed overs plus three legal balls, which equals 20.5 overs in decimal calculations.
Does NRR use only a team’s wins?
No. It uses the matches that count under the event’s regulations, and losses can affect NRR too.

Editorial note: Updated October 26, 2026. The previous example incorrectly used 18 overs for an opponent dismissed all out in a 20-over match; that NRR calculation has been corrected.
