World Football Elo Ratings
The World Football Elo Ratings is a ranking system for men's national association football teams that is published by the website eloratings.net. It is based on the Elo rating system but includes modifications to take various football-specific variables into account, like the margin of victory, importance of a match, and home field advantage. Other implementations of the Elo rating system are possible and there is no single nor any official Elo ranking for football teams.
Since being developed, the Elo rankings have been found to have the highest predictive capability for football matches.[1] FIFA's official rankings, both the FIFA World Rankings for men and the FIFA Women's World Rankings are based on a modified version of the Elo formula, the men's rankings having switched away from FIFA's own system for matches played since June 2018.[2]

- ↑ Guatemala is ranked much lower in the FIFA Ranking because they were inactive from September 2016 to August 2018 due to their suspension from FIFA. While this caused their FIFA Ranking to fall dramatically under the former system, their Elo rating remained the same.
- ↑ Northern Cyprus are not a member of FIFA and are not included in the FIFA Rankings. Also, they have played only 17 matches against other Elo-ranked teams, so their Elo rating is provisional.
- ↑ Martinique are also not members of FIFA, so are not included in the FIFA Rankings.
- ↑ Kuwait is ranked lower in the FIFA Ranking because they were inactive from October 2015 to December 2017 due to their suspension from FIFA. While this caused their FIFA Ranking to fall dramatically under the former system, their Elo rating remained the same.

- The biggest point gap
The biggest point gap between 1st and 2nd national team was between 14 March and 21 March 1885, when Scotland (at 2094) led by 205 points over 2nd ranked England (at 1889).[8]
Average ratings
Time averaged Elo or Elo-like scores are routinely used to compare chess player strengths.[9][10][11] The following is a list of the national teams with the highest average Elo score from 1 January 1970 to 1 January 2018. Before this time intercontinental play was fairly limited and many nations in Africa, North America, and Asia had played too few games yet to create a representative Elo score.
Overall average ratings
Time averaged Elo or Elo-like scores are routinely used to compare chess player strengths.[12][13][14]
Highest average over entire team history
This table is directly extracted from the eloratings.net website. The numbers represent may not be directly comparable. For England and Scotland they represent 146 years of matches (in 2018), for Ukraine 26 years, and for Montenegro 11 years. For Croatia and Slovakia the average is dominated by the single rating during the 50 years between the few games played between 1940 and 1943 and the rebirth of the countries in the 1990s. Likewise, South Africa's average is mostly determined by the 44 matches (of a 417 total in 2018) played in the 86 years before it rejoined FIFA in 1992.

Highest average ratings since 1970
This table is a list of the national teams with the highest average Elo score over approximately the last half century, from 1 January 1970 to 1 January 2018. Before this time intercontinental play was fairly limited and many nations in Africa, North America, and Asia had played too few games yet to create a representative Elo score. Only teams playing over the entire period are included. Short-lived or recently originated strong football teams, like East-Germany and Croatia, appear in the decades table below.

- ↑ Includes the record of the Great Britain Olympic football team in the 1908, 1912 and 1920 Olympics
- ↑ In the 1940s, most national teams did not play games until after the end of World War II, making comparison of countries for this decade weak. For example, Mexico did not play any matches between Feb 1938 and July 1947, so that the average over the decade mostly reflects the single Elo rating achieved in February 1938
- ↑ Combined record of Yugoslavia (1990–1992) and FR of Yugoslavia (1994–1999)
- ↑ Combined record of Czechoslovakia (1990–1992) and Czech national football teams (1993–1999)

History and overview
The Elo system, developed by Hungarian-American mathematician Árpád Élő, is used by FIDE, the international chess federation, to rate chess players, and by the European Go Federation, to rate Go players. In 1997, Bob Runyan adapted the Elo rating system to international football and posted the results on the Internet.[37] He was also the first maintainer of the World Football Elo Ratings web site, currently maintained by Kirill Bulygin. Other implementations of the Elo rating system are possible [38] but the Runyan system is the best known.
The Elo system was adapted for football by adding a weighting for the kind of match, an adjustment for the home team advantage, and an adjustment for goal difference in the match result.
The factors taken into consideration when calculating a team's new rating are:
- The team's old rating
- The considered weight of the tournament
- The goal difference of the match
- The result of the match
- The expected result of the match
The different weights of competitions in descending order are:
- World Cup Finals
- Continental championships finals and Intercontinental tournaments
- World Cup and Continental championship qualifiers
- All other tournaments
- Friendly matches
The ratings consider all official international matches for which results are available. Ratings tend to converge on a team's true strength relative to its competitors after about 30 matches.[39] Ratings tend to converge on a team's true strength relative to its competitors after about 30 matches; ratings for teams with fewer than 30 matches are considered provisional.
Comparison with other systems
A 2009 comparative study of eight methods found that the implementation of the Elo rating system described below had the highest predictive capability for football matches, while the men's FIFA ranking method (2006–2018 system) performed poorly. [38]
The FIFA World Rankings is the official national teams rating system used by the international governing body of football. The FIFA Women's World Rankings system has used a modified version of the Elo formula since 2003. In June 2018, the FIFA ranking switched to an Elo-based ranking as well, starting from the current FIFA rating points.[40] The major difference between the World Football Elo Rating and the future men's FIFA rating system is that the latter will not consider goal differential and will count a penalty shoot-out as a win/loss rather than a draw; thus, a 7:0 blowout will be considered equal to a 7:6 penalty shoot-out win (neither method distinguishes a win in extra time from a win in regular time). The FIFA method will further be less sensitive to the difference in ratings and more sensitive to match status.[41] Finally, World Football Elo Ratings considers all official international matches for which results are available, including those involving "unaffiliated" teams that are not a member of FIFA.
Calculation principles
The ratings are based on the following formulae:
where
Where;
= The new team rating | |
= The old team rating | |
= Weight index regarding the tournament of the match | |
= A number from the index of goal differences | |
= The result of the match | |
= The expected result | |
= Points Change |
"Points Change" is rounded to the nearest integer before updating the team rating.
Status of match
The status of the match is incorporated by the use of a weight constant. The constant reflects the importance of a match, which, in turn, is determined entirely by which tournament the match is in; the weight constant for each major tournament is:
Tournament or Match type | Index (K) |
---|---|
World Cup, Olympic Games (1908–1980) | 60 |
Continental championship and intercontinental tournaments | 50 |
World Cup and Continental qualifiers and major tournaments | 40 |
All other tournaments | 30 |
Friendly matches | 20 |
The FIFA adaptation of the Elo rating will feature 8 weights, with the knockout stages in the World Cup weighing 12x more than some friendly matches.[41]
Number of goals
The number of goals is taken into account by use of a goal difference index.
If the game is a draw or is won by one goal
If the game is won by two goals
If the game is won by three or more goals
- Where N is the goal difference
Table of examples:
Goal Difference | Coefficient of K (G) |
---|---|
0 | 1 |
+1 | 1 |
+2 | 1.5 |
+3 | 1.75 |
+4 | 1.875 |
+5 | 2 |
+6 | 2.125 |
Result of match
W is the result of the game (1 for a win, 0.5 for a draw, and 0 for a loss). This also holds when a game is won or lost on extra time. If the match is decided on penalties, however, the result of the game is considered a draw (W = 0.5).
Expected result of match
We is the expected result (win expectancy with a draw counting as 0.5) from the following formula:
where dr equals the difference in ratings (add 100 points for the home team). So dr of 0 gives 0.5, of 120 gives 0.666 to the higher-ranked team and 0.334 to the lower, and of 800 gives 0.99 to the higher-ranked team and 0.01 to the lower.
The FIFA adaptation of the Elo rating will not incorporate a home team advantage and will have a larger divisor in the formula (600 vs 400), making the points exchange less sensitive to the rating difference of two teams.[41]
Examples for clarification
The same example of a three-team friendly tournament on neutral territory is used as on the FIFA World Rankings page. Beforehand team A had a rating of 630 points, team B 500 points, and teams C 480 points.
The first table shows the points allocations based on three possible outcomes of the match between the strongest team A, and the somewhat weaker team B:
Team A | Team B | Team A | Team B | Team A | Team B | |
Score | 3 : 1 | 1 : 3 | 2 : 2 | |||
---|---|---|---|---|---|---|
20 | 20 | 20 | 20 | 20 | 20 | |
1.5 | 1.5 | 1.5 | 1.5 | 1 | 1 | |
1 | 0 | 0 | 1 | 0.5 | 0.5 | |
0.679 | 0.321 | 0.679 | 0.321 | 0.679 | 0.321 | |
Total (P) | +9.63 | -9.63 | -20.37 | +20.37 | -3.58 | +3.58 |
When the difference in strength between the two teams is less, so also will be the difference in points allocation. The next table illustrates how the points would be divided following the same results as above, but with two roughly equally ranked teams, B and C, being involved:
Team B | Team C | Team B | Team C | Team B | Team C | |
Score | 3–1 | 1–3 | 2–2 | |||
---|---|---|---|---|---|---|
20 | 20 | 20 | 20 | 20 | 20 | |
1.5 | 1.5 | 1.5 | 1.5 | 1 | 1 | |
1 | 0 | 0 | 1 | 0.5 | 0.5 | |
0.529 | 0.471 | 0.529 | 0.471 | 0.529 | 0.471 | |
Total (P) | +14.13 | -14.13 | -15.87 | +15.87 | -0.58 | +0.58 |
Team B drops more points by losing to Team C, which has shown about the same strength, than by losing to Team A, which has been considerably better than Team B.

In another World Cup qualifier in October 2004 Liechtenstein (ER 1049) held the 853 points higher rated Portuguese team (ER 1902) to a 2:2 draw.
