How do you calculate RPI in college basketball?

Answer 1

The RPI calculates 3 percentages: team's winning percentage, opponents' winning percentage, and opponents' opponents' winning percentage.?

To calculate?the team's winning percentage:

Wins: home wins * 0.6 + road wins * 1.4 + neutral wins?

Losses: road losses * 0.6 + home losses * 1.4 + neutral losses?

Then calculate your winning percentage using wins / (wins + losses). This % is weighted 25%.

Opponents' winning percentage is calculated using the exact same method as shown above, however exclude all games played with the team (that's RPI is being calculated). This % is then weighted 50%.?

Opponents' opponents' winning percentage is calculated by the average of the team's oppenents adjusted winning %. Simply, use the same method above for calculating the oppenents' winning percentage, however using it for the opponents' opponent and excluding only the team once again (not the opponent). Repeat this method for each team, and average the winning percentage. This % is then weighted 25%.?

Finally, add up all scaled RPI points, and get a total RPI ranking.
