Country coefficient
The country coefficient is used to rank the football associations of North America, and thus determine the number of clubs from an association that will participate in the CONCACAF Champions League and the CONCACAF SuperLiga.

The CONCACAF ranking determines the number of teams competing in the first season after the publication of the ranking, not in the season after next like UEFA. Thus, the rankings at the end of the 2016–17 season determine the team allocation by association in the 2017–18 (not 2018–19) CONCACAF season.

This coefficient is determined by the results of the clubs of the associations in the CONCACAF Champions League and the CONCACAF SuperLiga games over the past five seasons. Two points are awarded for each win by a club, and one for a draw (points are halved in the qualifying and playoff rounds). Results determined by extra time do count in determining the allocation of points, but results determined by penalty-shootouts do not affect the allocation of points, other than for bonus points given for qualification into the latter rounds of the Champions League or the SuperLiga. The number of points awarded each season is divided by the number of teams that participated for that association in that season. This number is then rounded down to three decimal places (e.g. 2⅔ would be rounded to 2.666).

To determine a country's coefficient for a particular season, the coefficients for the last five seasons are added. Bonus points are added to the number of points scored in a season. Bonus points are allocated for:


 * Clubs that reach the quarter-finals, semi-finals, or final, or that win either the CONCACAF Champions League or the CONCACAF SuperLiga (1 bonus point).
 * Clubs that qualify for the group stage of the Champions League (4 bonus points).
 * Clubs that qualify for the round of 16 of the Champions League (5 bonus points).

Note that UEFA does not grant a bonus point for winning their tournaments. So, if the UEFA Champions League or Europa League final finishes drawn and is decided by penalties, both teams' associations receive the same number of points. The ranking system above always awards more points to the winners' associations.

Current ranking
The ranking below takes into account of each association's performance in North American competitions from 2013–14 to 2017–18, with the 2017–18 season currently taking place. For 2013–14, points earned in the actual CONCACAF Champions League are used. From 2014–15 onward, the simulated version of the Champions League and SuperLiga are used.

The final ranking at the end of the 2017–18 season will be used to determine the number of places for each association in the 2018–19 CONCACAF Champions League and 2018–19 CONCACAF SuperLiga.

As of the end of the 2017–18 season, the coefficients are as follows (highest point total for a season in bold):

Club coefficient
The club coefficient rankings are determined by the results of clubs in the CONCACAF Champions League and the CONCACAF SuperLiga over the previous five seasons, as well as by the coefficient of the clubs' association. The club coefficient is the sum of the points earned by the club over the five seasons, but no less than 20% of the club's association coefficient. Prior to the 2018 club rankings, teams received the sum of their points earned over the last five seasons plus 20% of the club's association coefficient. For 2013–14, points earned in the actual CONCACAF Champions League are used. From 2014–15 onward, the simulated version of the Champions League and SuperLiga are used.

The clubs receive two points for a win, one point for a draw, and no points for a defeat in games of the main stages of the Champions League and the SuperLiga. Results determined after extra-time are included in this method, however results determined after penalty shoot-outs are not (the result is considered a draw). Bonus points for entering the SuperLiga group stage are not additional to win/draw points; they provide a minimum points allowance for participating clubs, whereas bonus points for entering the Champions League group stage (and those for qualifying to the knockout stage) are additional to win/draw points.

Qualifying round results are only taken into account if the team is eliminated in one of the rounds (see table below). Otherwise, the qualifying round results are taken into account only for the calculation of the association's coefficient and are halved. The clubs do not receive any points for elimination in the Champions League second qualifying round or the play-off round because those teams move to the SuperLiga and receive points from participation in that competition

This ranking is used to determine a club's seeding in club competition draws. Note that UEFA does not grant a bonus point for winning their tournaments. So, if the UEFA Champions League or Europa League final finishes drawn and is decided by penalties, both teams receive the same number of points. The ranking system above always awards more points to the winners of the final.
