PORT CALCULATOR
Ortg Drtg Calculator
Calculate offensive and defensive ratings per 100 possessions to analyze team performance in sports.
What is the Ortg Drtg Calculator & How does it work?
Offensive Rating (ORtg) measures how efficiently a team scores points. It is calculated by taking the total points scored divided by the number of possessions used, then multiplying by 100.
Defensive Rating (DRtg) measures how well a team defends and prevents opponents from scoring. It is calculated by taking the total points allowed divided by the number of possessions given up, then multiplying by 100.
ORtg = left(frac{Points}{Possessions}right) times 100
ORtg = Offensive Rating, Points = Total points scored, Possessions = Number of possessions used

Frequently Asked Questions
How do I calculate Offensive Rating?

What if my team has a high number of turnovers?
Turnovers can increase the number of possessions, which might lower your Defensive Rating but could also affect Offensive Rating negatively.
How do I interpret the results?
A higher ORtg indicates better offensive efficiency, while a lower DRtg suggests better defensive performance.
Is there a difference between ORtg and eFG%?
ORtg is a broader measure of offensive efficiency including all aspects, whereas eFG% specifically measures effective field goal percentage.
