Net run rate (NRR), explained
Net run rate decides more league places than any other tiebreaker. Here's exactly how it works, with a full example you can check by hand.
Net run rate (NRR) is how fast a team scores minus how fast its opponents score against it, over the whole tournament. A positive NRR means you score quicker than you concede. When two teams finish level on points, the one with the higher NRR usually goes above — so the margin of every win and loss counts, not just the result.
The formula
NRR = (total runs scored ÷ total overs faced) − (total runs conceded ÷ total overs bowled)
Both halves are run rates — runs per over. The first is your batting rate across every match, the second is your opponents' batting rate against you. Everything is added up first and divided once at the end.
A worked example
Colony Kings play three 20-over matches:
| Match | Colony Kings batted | Opponent batted |
|---|---|---|
| 1 — won | 168/5 (20) | 142/9 (20) |
| 2 — lost | 121 all out (17.2) | 125/3 (16.4) |
| 3 — won | 150/4 (18.1) | 149/7 (20) |
Runs scored: 168 + 121 + 150 = 439. Overs faced:20 + 20 + 18.1. Match 2 counts as 20, not 17.2, because Colony Kings were all out (more on that below), and 18.1 overs is 18 overs and 1 ball. That's 349 balls, or 58.167 overs. Batting rate: 439 ÷ 58.167 = 7.547.
Runs conceded: 142 + 125 + 149 = 416. Overs bowled:20 + 16.4 + 20 — that's 340 balls, or 56.667 overs. Bowling rate: 416 ÷ 56.667 = 7.341.
NRR = 7.547 − 7.341 = +0.206. You can check it in the NRR calculator.
Overs are not decimals
An over has six balls, so 16.4 overs is 16 overs and 4 balls — 16⅔ overs, or 16.667. Divide by 16.4 and every rate comes out wrong. The safest way is to count balls: overs × 6 + the balls after the dot, then divide by 6 at the end. 16.4 overs is 16 × 6 + 4 = 100 balls = 16.667 overs.
The all-out rule
A team bowled out before its overs are up is charged its full quota of overs. In match 2, Colony Kings were all out in 17.2 overs, but their NRR treats it as 121 runs in 20 overs. Without this rule a team could protect its run rate by getting bowled out quickly.
The rule works one way only. A team that chases a target down early — Colony Kings in match 3 — is charged just the overs it faced, which is why a fast chase lifts NRR.
The mistakes that make points tables wrong
- Averaging match NRRs.Colony Kings' three match NRRs are +1.300, −1.450 and +0.807; their average is +0.219, but the real NRR is +0.206. Add up runs and overs first, then divide.
- Dividing by decimal overs. 17.2 overs is 17.333, not 17.2.
- Forgetting the all-out rule— the most common reason two people's tables disagree.
- Counting abandoned matches.A match with no result usually doesn't count towards NRR at all.
Rain-shortened matches
If a match is shortened before it starts, use the overs each side was actually allotted — a 10-over match counts as 10 overs, and the all-out rule charges 10. Professional cricket has extra rules for matches decided by DLS; for a local tournament, the fair approach is to write down how you'll handle a shortened match before the tournament starts, and stick to it.
When NRR is level too
It almost never happens to three decimal places, but decide the next tiebreaker in advance — usually the head-to-head result, then a draw of lots. Like every tiebreaker, it only feels fair if every captain heard it before the first ball.
Let the scorer do it
On SportsScorer every ball is scored live, so the points table — with NRR worked out exactly this way, all-out rule included — updates itself the moment a match ends. Nobody argues over a spreadsheet. Create a free tournament, or read how to organize a cricket tournament.
