Calculate NRR for cricket points tables (IPL, World Cup, Leagues)
Team Performance (Batting)
Use decimal for balls (e.g., 180.4 for 180 overs 4 balls)
Opponent Performance (Bowling)
If team was All Out, enter full quota of overs.
Net Run Rate
+0.000
Team Run Rate: 0.00
Conceded Run Rate: 0.00
How to Calculate Run Rate in Points Table
Net Run Rate (NRR) is the primary method used in cricket tournaments to rank teams that have finished with the same number of points. Whether it's the IPL, the Cricket World Cup, or local leagues, understanding how to calculate run rate in the points table is essential for analyzing a team's standing and their chances of qualification.
The Net Run Rate Formula
The mathematical formula for Net Run Rate is actually quite straightforward. It is the difference between a team's scoring rate and the rate at which they concede runs.
NRR = (Total Runs Scored / Total Overs Faced) – (Total Runs Conceded / Total Overs Bowled)
Essentially:
Step 1: Calculate the average runs your team scores per over (Team Run Rate).
Step 2: Calculate the average runs your opponents score against you per over (Opponent Run Rate).
Step 3: Subtract the Opponent Run Rate from the Team Run Rate.
Detailed Calculation Steps
1. Converting Overs to Decimals
Cricket overs are not standard decimals. An over consists of 6 balls. Therefore, 10 overs and 3 balls is denoted as 10.3 in scorecards, but mathematically it is 10.5 (since 3/6 = 0.5).
1 Ball = 1/6 ≈ 0.166 overs
2 Balls = 2/6 ≈ 0.333 overs
3 Balls = 3/6 = 0.500 overs
4 Balls = 4/6 ≈ 0.666 overs
5 Balls = 5/6 ≈ 0.833 overs
2. Handling "All Out" Scenarios
This is a critical rule often overlooked when learning how to calculate run rate in points tables. If a team is bowled out (loses all 10 wickets) before completing their full quota of overs (e.g., 20 in T20 or 50 in ODI), the run rate calculation assumes they faced the full quota of overs.
Example: If Team A is all out for 140 in 18.2 overs in a T20 match, the NRR calculation uses 140 divided by 20.0, not 18.2.
Example Calculation
Let's assume Team X has played 2 matches:
Match 1: Scored 180/6 in 20 overs. Conceded 160/8 in 20 overs.
Match 2: Scored 150/10 in 19 overs (All Out). Conceded 140/9 in 20 overs.
Total Runs Scored: 180 + 150 = 330 Total Overs Faced: 20 + 20 (due to All Out rule) = 40 Team Run Rate: 330 / 40 = 8.25
Total Runs Conceded: 160 + 140 = 300 Total Overs Bowled: 20 + 20 = 40 Conceded Run Rate: 300 / 40 = 7.50
Net Run Rate: 8.25 – 7.50 = +0.750
Why is NRR Important?
In tightly contested tournaments, points often end up tied. A high positive NRR implies a team wins matches by big margins or loses by narrow margins. A negative NRR suggests heavy defeats or narrow wins. This metric acts as the tie-breaker to determine semi-finalists or champions.

// If input is 19.10 (not standard cricket notation but possible user error), careful parsing needed.
// Standard notation assumes single digit ball count usually.
// We will treat the decimal part strictly. 0.1 is 1 ball, 0.4 is 4 balls.
var decimalPart = parseFloat("0." + parts[1]);
// Re-calculating balls based on the user input logic e.g. 10.4 -> 4 balls.
// A reliable way for simple inputs like 10.4 is:
balls = parseInt(parts[1]);
// Correction for inputs like 10.10 or 10.05
// Assuming standard cricket input where .1 to .5 are balls.
// If user types 10.6, that is usually 11 overs, but let's handle strictly.
}
// Re-approach: Use Math.floor to separate integers
var o = Math.floor(oversInput);
var decimalVal = oversInput – o;
// In cricket notation 19.4 means 19 overs + 4 balls.
// But floating point math: 19.4 – 19 = 0.40000000003
var b = Math.round(decimalVal * 10);
if (b >= 6) {
// Technically invalid over notation (e.g. 10.7), but we normalize it.
// 10.6 -> 11.0
