ICC ODI Table

Last updated: 6 Apr, 2005

Summary of the Ratings Method:

A rating is worked out by dividing the points scored by the matches played, with the answer given to the nearest whole number.
After every ODI, the two teams each receive a certain number of points, based on a mathematical formula. Each team's new points total is then divided by its new matches total to give their updated rating.
Matches abandoned with no result are always ignored. Also, only ODIs between full members are rated, so matches involving the Netherlands, Canada or Namibia at the ICC Champions Trophy, World Cup or other such tournaments will not be included.
The amount by which your rating improves after winning an ODI depends on the rating of your opponent. A win over a much stronger team (ie. one with a much higher rating than your own) boosts your rating far more than beating a much weaker opponent. Conversely, losing to a much stronger team will not cause your rating to drop too far but losing to a weaker side would.
The country with the highest rating is officially regarded as the best ODI team in world cricket, and will hold a specially commissioned ICC ODI Trophy, while it tops the table

Period Covered:

The ratings will be based on up to three years of results.
The inaugural table reflects all ODIs played since 1st August 2000.
All ODIs played until the start of next August will be added on to this table.
In every subsequent August, the first year of results will be dropped from the table, so it will then cover the most recent two years of results. Thus once a year, the rankings will change overnight without any new ODIs being played.

Weighting of Results:

All matches included within the rankings will always fall into one of three time periods. Weightings are applied to these three groups of matches so that the rankings more fully reflect recent form. These weightings are:
- Period One covers the first year of matches (weighting: one-third)
- Period Two covers the second year of matches (weighting: two-thirds)
- Period Three covers the remaining more recent matches (weighting: one)
The number of matches played and the number of points earned in each period is multiplied by the weighting factor. Example: if a team played 33 ODIs in Period One, the weighting of one third means this counts as 11 matches towards their rating. Similarly, 21 ODIs played in Period Two count as 14. Add to that 10 played in Period Three to bring it to a total of 35. A small technical adjustment ensures that, for all teams, the total number of matches and rating points is always a whole number.

Ratings Formula:

After each match, the two teams each score a certain number of rating points. These points are then added to their existing total and used to generate their updated ratings. The number of points a team scores is based on two factors:
1. the result of the match and
2. the gap between the ratings of the two teams going into the match.
There are two different formulas. One applies if the gap between the two teams' ratings is less than 40 points, the other if the gap is 40 points or more. The rating points you score from a particular ODI is as follows:

Case 1 - gap between the two teams' ratings is less than 40 points:
- if you win, you score 50 points more than your opponent's rating
- if you lose, you score 50 points less than your opponent's rating
- if you tie, you score your opponent's rating
Case 2 - gap between the two teams' ratings is 40 points or more:
- If the stronger team wins, it scores 10 points more than its own rating while the weaker team scores 10 points less than its own rating
- If the weaker team wins, it scores 90 points more than its own rating while the stronger team scores 90 points less than its own rating
- If the match is tied, the stronger team scores 40 points less than its own rating and the weaker team scores 40 points more than its own rating
