Cricket Net Run Rate Calculator
Calculate NRR for league standings and tournament qualification scenarios.
Team Performance (Batting)
Use .1 to .5 for balls (e.g. 19.3 is 19 overs 3 balls)
Opponent Performance (Bowling)
If all out, count as full quota of overs (e.g. 20 or 50)
Net Run Rate
+0.000
Team Run Rate: 0.00
Opponent Run Rate: 0.00
How is Net Run Rate (NRR) Calculated in Cricket?
Net Run Rate (NRR) is the preferred method for breaking ties in multi-team cricket tournaments like the IPL, ICC World Cup, and T20 leagues. It measures a team's winning margin or losing margin relative to the overs played.
The Net Run Rate Formula
The calculation essentially compares the rate at which a team scores runs against the rate at which they concede runs.
NRR = (Runs Scored / Overs Faced) – (Runs Conceded / Overs Bowled)
Where:
- Runs Scored / Overs Faced is the team's average runs per over (Team Run Rate).
- Runs Conceded / Overs Bowled is the average runs conceded per over (Opponent Run Rate).
Crucial Rules for Calculating Overs
One common confusion is how to handle partial overs. In cricket statistics, overs are often written as 10.4 (meaning 10 overs and 4 balls). However, mathematically, an over consists of 6 balls. Therefore:
- 1 ball = 1/6 over ≈ 0.166
- 2 balls = 2/6 over ≈ 0.333
- 3 balls = 3/6 over = 0.5
- 4 balls = 4/6 over ≈ 0.666
- 5 balls = 5/6 over ≈ 0.833
Important Note on All-Outs: If a team is bowled out (all out) before completing their full quota of overs (e.g., bowled out in 45 overs in a 50-over match), the calculation uses the full quota (50 overs) as the divisor, not the actual overs faced. This penalizes the team for losing all their wickets.
Example Calculation
Let's assume Team A plays one match in a T20 tournament:
- Batting: Team A scores 180 runs in 20 overs.
- Bowling: Team A restricts the opponent to 150 runs in 20 overs.
Step 1: Calculate Team Run Rate
180 runs / 20 overs = 9.00
Step 2: Calculate Opponent Run Rate
150 runs / 20 overs = 7.50
Step 3: Calculate NRR
NRR = 9.00 – 7.50 = +1.500
Why is NRR Important?
In league formats, multiple teams often finish with the same number of points. NRR acts as the primary tie-breaker. A high positive NRR indicates dominant victories, while a negative NRR suggests narrow wins or heavy defeats.
