What is RPI?
-
RPI stands for Ratings Percentage Index and is used to compare sports teams. While it could be applied to any sport, it is specifically used for college basketball because it helps factor in a strength-of-schedule component in an objective manner among a large number of teams, many of which do not play each other. It takes into account how the team did, how tough its opponents were and how tough of a schedule the opponents played. It is most notably used as one factor in deciding which teams get accepted into the NCAA Tournament.
Calculate Winning Percentage
-
The team's winning percentage counts for 25 percent of the RPI. To determine this component, total the number of wins and losses. Multiple the number of home wins by 0.6, home losses by minus 1.4, neutral-site wins by 1, neutral-site losses by minus 1, road wins by 1.4 and road losses by minus 0.6. Then add the numbers.

Calculate Opponents' Winning Percentage
-
The total winning percentage of all opponents played by a team counts for 50 percent of the RPI. To determine this component, total the number of wins and losses. Multiple the number of home wins by 0.6, home losses by minus 1.4, neutral-site wins by 1, neutral-site losses by minus 1, road wins by 1.4 and road losses by minus 0.6. Then add the numbers.
Calculate Opponents' Opponents' Winning Percentage
-
The opponents' opponents' winning percentage counts for 25 percent of the RPI. To determine this component, total the number of wins and losses for all of the teams that played any team's opponents. Multiple the number of home wins by 0.6, home losses by minus 1.4, neutral-site wins by 1, neutral-site losses by minus 1, road wins by 1.4 and road losses by minus 0.6. Then add the numbers.
Calculate RPI
-
Multiply winning percentage by 0.25, opponents' winning percentage by 0.5 and opponents' opponents' winning percentage by 0.25, then add the numbers. This is a team's RPI.
