Net run rate is a team's scoring rate minus the rate at which it concedes runs, calculated across the matches that count in a competition stage. To calculate it correctly, total the runs and overs first, following the ICC's explanation of the calculation. For the ICC Men's T20 World Cup 2026, a side bowled out early is charged its full allocation of overs, and Super Overs are excluded.
| Question | Short answer |
|---|---|
| Formula | Total runs scored / overs faced, minus total runs conceded / overs bowled |
| Does 16.3 mean 16.3 overs? | No. It means 16 overs and three balls, or 16.5 overs |
| What is used below? | Invented scores for worked examples, not real match results |
How to calculate net run rate with an example
Imagine Team A makes 180 in 20 overs and restricts Team B to 160 in 20 overs. Team A's scoring rate is 180 divided by 20, or 9. Its conceding rate is 160 divided by 20, or 8. Subtracting the second figure from the first gives a net run rate of +1.000.
The same match produces -1.000 for Team B: it scored at 8 an over and conceded at 9. The sign describes which rate was higher. The three decimal places are a way to display the calculation; they do not mean that one extra decimal place changes the underlying result.
Now give Team A a second match. Its opponent scores 100 in 20 overs, and Team A reaches 101 in exactly 10 overs. For that match alone, Team A scores at 10.1 runs an over and concedes at 5. The difference is +5.100. These numbers are deliberately simple enough to check with ordinary division.
Across the two matches, however, Team A has scored 281 runs in 30 overs and conceded 260 runs in 40 overs. Its combined calculation is 281 / 30 minus 260 / 40. That is 9.366667 minus 6.5, producing approximately +2.867.
Averaging the two individual match figures would produce a different answer: (1.000 + 5.100) / 2 = 3.050. That shortcut gives equal weight to unequal innings lengths. Keeping separate running totals for runs scored, overs faced, runs conceded and overs bowled avoids this mistake.
Why cricket overs are not decimal numbers
The ICC competition playing conditions, clause 17.1, define an over as six valid balls. Convert incomplete overs into balls before doing arithmetic. A scorecard entry of 16.3 is 99 balls: 16 multiplied by six, plus three. Dividing 99 by six gives 16.5 overs.
For another calculation, 132 runs in 16.3 overs is 132 / 16.5, or 8 runs per over. Dividing by 16.3 instead produces about 8.098, an inflated answer. Both calculations look plausible on a screen, which is why checking the denominator is more useful than staring at the final decimal.
When adding innings, the ball method also prevents carrying errors. For example, 16.4 overs and 18.5 overs total 100 plus 113 balls. The combined 213 balls equal 35 overs and three balls, written 35.3 in cricket notation. For division, that becomes 35.5 overs. Keep the notation and the numerical value separate.
What happens to net run rate when a team is all out?
Clause 16.10.7 uses the full entitled quota for an all-out innings. In a hypothetical uninterrupted 20-over game, 120 all out in 17 overs therefore contributes 120 runs and 20 overs to the calculation. Its scoring-rate component is 6, not approximately 7.059.
If the opponent then scores 121 in 18 overs, the losing side's NRR for this example is 120 / 20 minus 121 / 18, approximately -0.722. Notice that the two denominators differ. Being dismissed early and completing a successful chase are different inputs, even when both innings finish before the scheduled limit.
Do rain, Super Overs and points change the calculation?
Only matches with results count under these tournament rules. Super Over runs and overs stay outside NRR. Rain-affected games decided using DLS have special credited-score rules, so a calculation copied mechanically from the original innings totals can be wrong. Check clause 16.10.7 before adding such a match.
For teams level on points in the 2026 tournament groups, wins came before NRR in the ordering criteria. Head-to-head results followed NRR, with the specified pre-tournament rankings as the remaining fallback. NRR therefore answers one part of a table question, rather than replacing the competition's full qualification rules.
