What is RPI?

RPI, short for Rating Percentage Index, is a metric used in college basketball, and sometimes the NBA, to rank or determine the strength of a team based on their winning percentage and their strength of schedule. The strength of schedule (SOS) includes both the team's direct opponent winning percentages and the winning percentage of their opponent's opponents.

Example Calculation 1

Let's assume the following values:

Using the formula:

\[ RPI = 0.25 \times 0.75 + 0.5 \times 0.60 + 0.25 \times 0.55 = 0.625 \]

The Rating Percentage Index is 0.625.

Example Calculation 2

Let's assume the following values:

Using the formula:

\[ RPI = 0.25 \times 0.80 + 0.5 \times 0.70 + 0.25 \times 0.65 = 0.725 \]

The Rating Percentage Index is 0.725.
