How to calculate the Net Run Rate?

Net Run Rate (NRR) has become the preferred method of breaking ties in multi-team one-day international tournaments. It is often misunderstood, but really quite simple to understand.

The net running rate of a team is determined by deduction from the average runs per team over the competition, with the average runs per team over the competition.

How to calculate the Net Run Rate?

If a team is all out with less than its maximum excess quota, the net rate of execution estimate would be based on the entire excess quota, and not on the total amount of excesses it would have got.

For net run rate calculations only those matches in which the results are obtained will be counted. If a match is abandoned, but the outcome of the Duckworth / Lewis team will be accredited to Team 2’s Par Score for net running rate purposes on the abandonment of the same number of Team 2 overruns.

Where a match is concluded but with Duckworth/Lewis having been applied at an earlier point in the match, Team 1 will be accredited with 1 run less than the final Target Score for Team 2 off the total number of overs allocated to Team 2 to reach the target.

Let’s take as an example South Africa’s net run-rate in the 1999 World Cup. South Africa’s listing in the Group A points table published in the group stages was as follows:

                      P  W  L NR T Pts Net-RR    For        Aga 
South Africa          3  3  -  - -   6 +1.495  678/147.2  466/150 

The columns we are looking at here are the last three: “Net-RR”, “For” and “Aga”. The figure in the “Net-RR” column is achieved by subtracting the answer of the division in the “Aga” column from the answer to the division in the “For” column.

To use this example:

South Africa had scored, so far in the tournament:

  • Against India, 254 runs (for 6 wkts) from 47.2 overs
  • Against Sri Lanka, 199 runs (for 9 wkts) from 50 overs
  • Against England, 225 runs (for 7 wkts) from 50 overs

Across the three games, South Africa scored 678 runs in a total of 147 overs and 2 balls (actually 147.333 overs), a rate of 678/147.333 or 4.602 rpo.


Teams opposing South Africa scored:

  • India, 253 (for 5 wkts) from 50 overs.
  • Sri Lanka, 110 all out from 35.2 overs.
  • England, 103 all out from 41 overs.

In the case of Sri Lanka and England, because they were all out before their allotted 50 overs expired, the run rate is calculated as if they had scored their runs over the full 50 overs.

Therefore, the run-rate scored against South Africa across the first three games is calculated on the basis of 466 runs in a total of 50 + 50 + 50 = 150 overs, a rate of 466/150 or 3.107 rpo.


The net run-rate is, therefore,

  4.602  Run-rate for 
  3.107  Run-rate against 
+ 1.495  ANSWER
