Net run rate (NRR) is the tie-breaker that decides countless T20 World Cup groups and IPL playoff places. It measures how much faster a team scores than its opponents over a whole tournament. This calculator takes a team's total runs scored and overs faced, and total runs conceded and overs bowled, and returns its NRR along with the two rates behind it.
How to use the net run rate calculator
- Add up the runs scored by the team in every completed match and enter the total.
- Add up the overs faced. If the team was bowled out in a match, use the full quota of overs for that innings (see below).
- Enter the runs conceded and overs bowled in the same way. If the team bowled the opposition out, count the full quota of overs.
- Read the NRR and the scoring and conceding rates.
The net run rate formula
NRR = (Total runs scored ÷ Total overs faced) − (Total runs conceded ÷ Total overs bowled)
Two rules make it work correctly:
1. Use tournament totals, not match averages
NRR is not the average of each match's run-rate difference. You must add up all runs and all overs first, and then divide. Averaging per-match figures gives a different answer and is a common mistake.
2. All out means the full quota of overs
Under ICC playing conditions, if a team is bowled out before its overs run out, its innings is counted as if it had faced the full quota. A team bowled out for 73 in 15 overs of a T20 is treated as scoring 73 in 20 overs, a rate of 3.65 rather than 4.87. The same applies when calculating the opposition's rate if your team bowls them out. This stops a team from benefiting from being bowled out quickly.
When a team successfully chases a target, only the overs it actually used count. A chase completed in 15.2 overs counts as 15.2 overs (92 balls), which is why quick chases improve NRR so much.
Worked example
A team after three T20 matches
- Match 1
- Scored 185/6 (20) – Conceded 160/8 (20)
- Match 2
- Scored 151/3 (20) – Conceded 150/9 (20)
- Match 3
- Scored 176/9 (20) – Conceded 177/4 (18.4) – lost
- Totals
- 512 in 60.0 overs – 487 in 58.4 overs
- NRR
- 8.533 − 8.301 = +0.232
In match 3 the opponents chased successfully in 18.4 overs, so only 18.4 overs go into the bowling total. Load this example into the calculator to check it.
How to read NRR
- Positive NRR means the team scores faster than its opponents on average.
- Negative NRR means the team concedes runs faster than it scores them.
- A big win changes NRR more early in a tournament, when there are fewer overs in the totals. Later on, each match moves it less.
Matches with no result and rain-reduced games
Matches that are abandoned without a result are normally left out of NRR. When a match is shortened by rain and decided on DLS, tournaments have special rules for which runs and overs go into the calculation. Each competition publishes these in its playing conditions, so check the ICC event playing conditions or the league's own rules for the exact treatment.
Why NRR matters so much
In a short T20 tournament, several teams often finish level on points. NRR then decides who goes through. That is why captains in the final group game sometimes chase targets as fast as possible, or try to restrict the opposition to a certain score. Our NRR qualification calculator works out exactly how big a win a team needs to pass a rival's NRR.
Common mistakes
- Forgetting the all-out rule. It changes NRR a lot for teams that are bowled out cheaply.
- Using overs as decimals. 58.4 overs is 352 balls, or 58.667 overs.
- Averaging per-match NRRs. Always total runs and overs first.
