Formula Used
The calculator uses the common rating percentage index structure: RPI = 25% winning percentage + 50% opponents winning percentage + 25% opponents opponents winning percentage. The winning percentage can be adjusted by site weights. Road wins can receive more value. Home losses can hurt more. Neutral games keep standard weight.
Weighted winning percentage equals weighted wins divided by weighted wins plus weighted losses. Opponents winning percentage measures the combined record of teams played. Opponents opponents percentage adds another schedule layer. Quality bonuses and penalties are optional.

Basketball RPI Analysis Guide
Why RPI Matters
Basketball RPI is a schedule based rating tool. It compares a team against its record and the strength around that record. A team with many wins can still rank lower when the schedule is weak. A team with fewer wins can rate better when opponents are stronger. This calculator helps you test both cases quickly.
What the Inputs Mean
The first group records team results by game location. Location matters because road games are harder. Many models reward road wins more than home wins. They also punish home losses more than road losses. Neutral court games usually stay balanced. You may edit all weights to match your league or tournament method.
Understanding Schedule Strength
Opponents winning percentage is the largest part of the formula. It shows whether the team played successful programs. Opponents opponents winning percentage adds deeper context. It checks whether those opponents built records against strong schedules. This prevents a misleading rating from easy wins.
Using Adjustments Carefully
The quality bonus field can reward strong wins. The bad loss penalty field can reduce the final score. These fields should be used with clear rules. For example, you may add a small bonus for beating a top ranked team away from home. You may subtract a penalty for losing to a very weak team at home.
Reading the Final Result
The base RPI shows the raw formula result. The adjusted RPI includes bonuses and penalties. A higher value means a stronger profile. The profile label gives a fast reading. It is not a guarantee of selection or ranking. It is a guide for comparison.
Practical Uses
Coaches can compare schedule plans before a season starts. Analysts can review tournament cases. Writers can explain why two records are not equal. Fans can test how one upset changes a team profile. The export buttons make results easy to save and share. This keeps each review organized.
FAQs
What is basketball RPI?
Basketball RPI is a rating percentage index. It blends team winning percentage, opponent strength, and opponent-opponent strength into one schedule-based score.
Does this calculator use weighted game locations?
Yes. It includes editable weights for home, road, and neutral wins or losses. You can keep defaults or enter your own method.
What is OWP?
OWP means opponents winning percentage. It measures the combined record of teams your selected team played, usually excluding direct games when available.
What is OOWP?
OOWP means opponents opponents winning percentage. It adds another schedule layer by measuring the strength of your opponents schedules.
Should I add quality win bonuses?
Add them only when your ranking method uses them. Keep the value small and consistent, so comparisons remain fair and repeatable.
Can this predict tournament selection?
No single rating can predict selection fully. This tool helps compare profiles, but committees may consider injuries, recent play, and other metrics.
Why is my RPI low with many wins?
Your opponents may have weak records. RPI rewards schedule strength, so wins against weaker teams may not raise the rating much.
Can I export the result?
Yes. After calculation, use the CSV or PDF buttons below the result table to save a clean report.
