Net run rate is a very important component in tournaments, and is often the margin that pins back a team from the semifinals. It is easily the most complicated thing I will be telling you about. So strap on your seat belts, get out your calculators, and let’s go.

Net Run Rate (commonly known as NRR) is basically a secondary component used to differentiate between 2 teams with the same number of points. So now if you’ll look at this points table:

So you’ll then notice that there are a few teams here who have a negative NRR. I’ll tell you why. So just look at the following formula:

Net Run Rate = (Your team’s runs scored/balls faced) – (Runs scored by opposition against you/balls faced)

So basically if you find that the NRR is positive (like it is in the case of South Africa, India, West Indies, and England), that means that they have scored more runs than their opposing teams, in fewer overs. If it is negative, however (like it is in the case of Ireland, Netherlands, and Bangladesh), then they have scored less runs than their opposition, in more overs. You can say that it is a measure of how well a team has done in relation to it’s opponents: the higher it is, the more dominance the team has had over it’s opponents.

It is possible for you to find the NRR of any team by yourself, and it’s pretty good fun. It’s also a good exercise your mental maths if done mentally. Just take note that if a side is bowled out, then it counts as they played the entire quota of overs. So here we go:

So now let’s say Team India is playing a T20 tournament, and these are the following results:

IND 166-6 (20)

BAN 131-8 (20 )

Lost to South Africa by 72 runs

RSA 204-8 (20)

IND 132-10 (19.4)

Beat Australia by 5 wickets

AUS 160-9 (20)

IND 162-5 (18.1)

Lost to Sri Lanka by 1 wicket

IND 120-10 (19.5)

SL 121-9 (17.5)

Beat England by 1 run

IND 172-10 (19.3)

ENG 171-10 (18.5)

So now we add up all the runs scored by India:

166+132+162+120+172= 752 runs

Then the balls faced: 120+120+109+120+120= 589 balls orĀ 98.1 overs.

So then we divide: 752/98.1 = 7.66

Now we add the opposing runs: 131+204+160+121+171= 787 runs

Then we add the balls faced: 120+120+120+107+120= 587 balls or 98.2 overs

Then we divide: 787/98.2 = 8.01

So then we subtract: 7.66-8.01 = -0.35.

So India’s NRR is -0.35

iplgeek says:

If it is the first match,then it would be (your runs scored/overs bowled) – (their r uns scored/overs bowled) in that first match, or in your run rate – their run rate for that match. This is why you see teams that have played only one game sometimes have outrageously high NRRs.
