UEFA calculates the coefficient of each club and association each season based on the clubs' results in the UEFA Champions League, UEFA Europa League and UEFA Europa Conference League. The season coefficients from the five most recent seasons are used to determine the positions of the associations in the access list (association coefficient) and to rank the clubs for seeding purposes (sporting club coefficient). In addition, the season coefficients from the ten most recent seasons are used to calculate revenue club coefficients for revenue distribution purposes only.
