Although the game has undoubtedly evolved, the traditional measures of player performances have not. As such, both parties recognised the need for an internationally recognised global system of assessing players’ performances which takes into account performances in all international and domestic T20 cricket. The complex algorithm which underpins the Index incorporates many performance metrics and will assist in more accurately defining a player’s worth in this format. It will assist in driving the global T20 narrative throughout the year.
The Index incorporates all major domestic T20 cricket. Furthermore, the Index uses a unique algorithm which incorporates performance metrics never before used to determine where players stand against their peers. The Index is calculated using data from all attributes of the game, including fielding. Being exclusively a T20 Index, strike rate and economy rate are as heavily weighted as runs scored and wickets taken, with dot ball and boundary percentages also being taken into account. In order to generate an accurate evaluation of each individual the algorithm also includes adjusted scoring based on:
Metrics are calculated using adjusted averages, so a player’s total points can go up or down. All metrics are Indexed and weighted to ensure that each attribute of a player’s performance is considered with key metrics having heavier weightings.
Individual metrics are also adjusted depending on the context of the performance within the match and the strength of the opposition players.
The Index takes into account performances by players taking part in both major T20 domestic tournaments and T20 internationals. Often the reason is that a player’s international commitments, including across other formats, may mean they have played very little T20 cricket during the qualifying period. Their other commitments may have also precluded them from playing in domestic T20 competitions both in their own countries and overseas.
All major domestic T20 tournaments are included as well as all T20 internationals.
The algorithm updates the standings for all players after each completed match and the results will be updated on the website every Monday.
Yes, all tournaments have a weighting based on the overall strength of the players within that tournament, so e.g. at present the IPL is weighted more heavily than the Bangladesh Premier League.
While it is true that Indian players are unable to participate in overseas leagues, those that play in the IPL and international cricket will be accruing points with the highest possible weighting (The IPL and International matches are joint highest weighted tournaments). Those Indian players who perform well in the IPL but don’t play for India will have a limitation on the points they can accrue but exceptional performances in the IPL could still see them top the Index.
The Index is measured over a rolling three-year period, with the most recent 12 months most heavily weighted to give priority to recent form. Three years provides a sufficient sample of data to obtain an accurate picture of where players sit against their peers. Points accrued from tournaments which took place three years ago drop off when the corresponding tournament begins in the current year.
The algorithm considers all attributes of the T20 game. Batting, bowling and fielding (and wicketkeeping where applicable) are all included in the overall Index.
All-rounders have more opportunity to accrue points, however a player’s maximum points vary depending on how much of an all-rounder they are (the percentage of games in which they bat and bowl). This allows the opportunity for a batter or a bowler to top the standings with a very strong performance in one attribute.
Points are awarded for fielding dismissals (catches, stumpings and run outs) and wicketkeepers can score additional points by conceding fewer byes than average.
No, the Index is calculated using adjusted averages, so points are not just accumulated. Poor performances can lead to a drop in the standings and a strong performance across a relatively small number of matches could see a player top the standings. However, additional positive adjustments are made for matches and tournaments won.
Index points can be accrued after one match – however a minimum number of matches must be played in a year to accrue full points. Additionally, specific batting and bowling metrics do not award full points until a certain number of balls have been faced/bowled. This ensures a large-enough sample size for each player to give confidence that their performance is being measured accurately.
No, bowling metrics are split by the stage of the match (Powerplay, middle overs and ‘death’ overs) with performance in each being weighted accordingly.
Every run scored or ball bowled is weighted based on the current pre-match Index points of the opposition batter/bowler. Runs scored vs the number one bowler will be worth more points than runs scored vs the 200th placed bowler. Likewise, wickets taken or economical overs bowled vs a top batter are worth more.
The algorithm includes adjusted metrics to normalise conditions, so e.g. batsmen who play at home at a low-scoring ground will not suffer accordingly. If they are outperforming the expected values, their Index points will increase. All metrics in any match affected by Duckworth Lewis are also adjusted accordingly.
The Federation of International Cricketers’ Associations (FICA) was established in 1998 to co-ordinate the activities of all national players’ associations which protect the interests of professional cricketers throughout the world. It brings together the world’s cricketers, regardless of nationality, religion, political persuasion or race, under an international body focused on matters of general interest to the game and its players.

The T20 Player Index (the Index) is administered by the Federation of International Cricketers’ Associations (FICA) and the Cricketer Magazine / Cricket Archive. The Index is a performance measurement system of all cricketers who currently play Twenty20 cricket (at both domestic and international level) anywhere in the world designed to determine who is “the best” Twenty20 cricketer in the world. The Index is not affiliated, associated, authorized, endorsed by, or in any way officially connected with the International Cricket Council (ICC) or any national cricket board, or any of their subsidiaries or their affiliates.
