The 2018 Calcutta Football League Premier Division was the 121st season of the CFL Premier Division, a state association football league within the Indian state of West Bengal.
The Championship title is awarded only to the Division A winner, while four teams from Division A are relegated to Division B at the end of the season and four teams from Division B are simultaneously promoted to Division A for the next season.
Notes: 1.^ After the completion of the single round robin, the teams will be divided into two groups of top 6 and bottom 4.
The top 6 teams will play against each other in a single-leg format, called the championship round, while the bottom 4 teams play against each other in the same single-leg format called the relegation round.
Each team carries forward their points and other records from the previous 1st round matches into the championship or the relegation round.
