Net run rate is the number that decides more cricket league tables than any other, and it is also the number people most often get wrong. It looks like a complicated statistic, but it is two divisions and a subtraction. This guide explains the formula, works through a full example, and covers the rule that catches out most first-time calculators.
The formula
Net run rate is runs scored per over, minus runs conceded per over. For a team, add up every run it scored and every over it faced across all its matches, then divide the first total by the second. Do the same for the runs it conceded and the overs it bowled, divide, and subtract the conceding rate from the scoring rate.
The result is a single number, usually shown to two or three decimal places. A positive figure means the team scores faster than it concedes, and a negative figure means the reverse. Teams that finish on equal points are usually separated by this number, which is why it matters.
A worked example
Suppose a team has scored 300 runs in total, across matches where it faced 50 overs. Its scoring rate is 300 divided by 50, which is six runs per over. Suppose it has conceded 240 runs across matches where it bowled 40 overs. Its conceding rate is 240 divided by 40, which is also six runs per over. Its net run rate is zero: it scores exactly as fast as it concedes.
Now change one number. If the same team had bowled 45 overs instead of 40 while conceding the same 240 runs, its conceding rate would fall to about 5.33 runs per over. Its net run rate would become about plus 0.67. Bowling more overs without conceding more runs improves the figure, which is one reason bowling depth matters in a tournament.
The all-out rule
When a team is bowled out before its overs are finished, the overs it faced count as its full quota. This stops a team from improving its scoring rate by getting out early. A team bowled out for 80 in 14 overs, with a 20-over quota, is treated as having faced 20 overs for the purpose of its rate.
The same logic applies to the bowling side. Check the ICC playing conditions and your competition's rules for the exact wording, because a local rule can change how an incomplete innings is treated.
Rounding and comparison
Net run rate is usually shown to two or three decimal places. Compare teams to the same precision, or a tie-break can hinge on rounding rather than on the cricket. Decide the number of decimal places before the season starts, and write it into the rules.
Why it matters across a season
Two teams on the same points can be separated by a few hundredths of a run per over, so a heavy defeat early in a season can cost a place at the end. Keep the match scores accurate, because a single wrong total changes the table. Recalculate net run rate after every result, and publish the working so teams can check it themselves.
Checking your own table
Take the total runs scored and overs faced for one team, do the division, and compare the answer with the figure in the table. If they differ, look for a match where the overs were recorded incorrectly, a rain-reduced innings that was not adjusted, or an all-out innings that was counted at its actual length.
Common questions
Net run rate is not the same as run rate. Run rate is only the scoring rate, while net run rate subtracts the rate at which the team concedes runs. A team can have a high run rate and a poor net run rate if it leaks runs at the same pace.
Match questions
Questions scorers actually ask
- 01 Is net run rate the same as run rate?
- No. Run rate is only the scoring rate. Net run rate subtracts the rate at which the team concedes runs, which is why it can be negative.
- 02 Does net run rate always decide a tie?
- Only if the competition uses it as the tie-break. Many leagues do, but the rules of your competition decide the order of tie-breaks.
- 03 Why does an all-out innings count as the full overs?
- So a team cannot improve its scoring rate by getting out early. The overs it faced are treated as its full quota.
