🏀 Game Score Calculator – Basketball Performance Indicator
Game Score Calculator is a powerful, easy-to-use online tool designed to help you measure and understand a basketball player’s performance using real in-game statistics. Based on the widely-recognized Game Score formula by John Hollinger, this tool offers a simplified way to evaluate how well a player performed in a single game, balancing both offensive and defensive contributions into one clear metric.
📈 What is Game Score?
Game Score is a performance rating system used in basketball analytics. It condenses a player’s total game impact into a single number, making it easy to compare different performances or track improvement over time. While traditional stats like points or rebounds can be misleading on their own, Game Score combines multiple variables—such as shooting efficiency, rebounds, assists, steals, turnovers, and fouls—into a balanced, meaningful indicator.
Formula:
Game Score = PTS + 0.4×FGM – 0.7×FGA – 0.4×(FTA – FTM) + 0.7×ORB + 0.3×DRB + STL + 0.7×AST + 0.7×BLK – 0.4×PF – TOV
