The performances of players and teams are evaluated over a yearly period which stretches from October 1 to September 30.
The CCR rating system follows a common points system for players on the basis of their performances in the Test and 50 over ODI formats. A separate system is used to reward players for T20 internationals which is further elaborated upon below
Batting  

A 35 in an innings  1 Point 
A 50 in an innings  1 Addiontional Point 
Every 25 runs thereafter in that particular innings  1 Point 
A century in an innings  3 Additional Points as Bonus 
A double century in an innings  6 Additional Points as Bonus 
A triple century in an innings  9 Additional Points as Bonus 
Bowling

Every subsequent catch  3 additional points as bonus 
Five catches in an innings  3 additional points as bonus 
Ten catches in an innings  6 Additional Points as Bonus 
Wicket Keeping

Since Twenty20 cricket puts greater emphasis on batsmen to get going from ball one, bowlers have their work cut out. A batsman’s strike rate and a bowler’s economic rate certainly come under greater scrutiny in this ‘slambang’ format of the game. Therefore, besides notching up points for runs scored and wickets taken, the CCR Twenty20 points system additionally rewards batsmen based on the number of deliveries they take to score runs and bowlers for their economy rate.
RUNS SCORED  BATTING POINTS 

11  20  10 
21  35  20 
36  50  50 
51  75  70 
76  100  100 
101  120  110 
121  135  120 
136 & Above  150 
Note: These points get multiplied to the absolute strike rate of the batsman (strike rate/100) to calculate the 'Grand Batting Points'. For example, if a batsman scores 50 runs in 25 balls, he would have earned 50 batting points according to the above scale. His strike rate would be 200 and his absolute strike rate would amount to 2. To calculate his Grand Batting Points, we simply have to multiply ‘batting points’ x ‘absolute strike rate i.e. 50 x 2 which equals 100. 
WICKETS TAKEN  BOWLING POINTS 

1  10 
2  30 
3  50 
4  70 
5  100 
6  110 
7  120 
In addition to the points bowlers earn for the number of wickets they take, their economy rate is also taken into consideration for which points are allocated as per the following:

Economy Rate  Economy Points 

Less than 4 per over  10 
Between 4 & 6 per over  5 
Between 6 & 9 per over  2 
More than 9 per over  0 
The sum of the 'Bowling Points' & the 'Economy Points' equal to a bowler’s 'Grand Bowling Points'.

Unlike the system used to award fielding points in Tests and 50 over ODIs, the Twenty20 points system doesn’t differ in its allocation of points to regular fielders and wicketkeepers based on the number of catches and stumpings taken. Here’s how points are awarded:
Catches/Stumpings  Fielding Points 

1  10 
2  20 
3  50 
4  70 
5 & above  100 
We all know the value teams attach to a Test win on the road, let alone to a series win. For this reason, the CCR Team Rating system ensures teams merit extra points for away Test match wins as compared to a win in their own backyard. For 50 over ODIs and Twenty20 internationals, a common system is used to rate team performances.
Test  

Outright win  6 points for home win 9 points for away win 
Draw/Tie  3 points each 
Defeat  no points 
Series Win  2 bonus points 
50 OVER ODI & T20 INTERNATIONAL  

Win  2 points 
Tie  1 point 
Abandoned match  no points 
In 50 over ODIs and Twenty20 internationals, bonus points for series or tournament wins will be based on the number of countries participating in the event. So if it’s a bilateral series, the series winner gets 2 bonus points, if it’s a triangular series, the winning team gets 3 points and so on. For the forthcoming ICC World Cup in 2015, since 14 teams will be involved, the world champions would earn 14 bonus points.
