What is NBA Usage Rate (USG%)?

Usage Rate, or Usage Percentage (USG%), is an advanced basketball metric that estimates the percentage of team plays a specific player "uses" while they are on the court. A play is considered "used" if it ends in a field goal attempt, a free throw attempt, or a turnover by that player.

In simple terms, it measures how much of the offense runs through a single player. High usage rates are typically reserved for superstars and primary ball-handlers who take the majority of the team's shots.

The Formula for Usage Rate

The standard formula used by most analytics platforms (like Basketball Reference) is:

USG% = 100 * [(FGA + 0.44 * FTA + TOV) * (Team MP / 5)] / [MP * (Team FGA + 0.44 * Team FTA + Team TOV)]
  • FGA: Field Goal Attempts
  • FTA: Free Throw Attempts (multiplied by 0.44 to account for "and-ones" and technicals)
  • TOV: Turnovers
  • MP: Minutes Played
  • Team MP / 5: Normalizes the team minutes for a single player slot on the floor.

How to Interpret Usage Rate

Understanding the numbers helps put a player's performance into context:

  • 30% +: Elite superstars. These players are the focal point of the offense (e.g., Giannis Antetokounmpo, Stephen Curry).
  • 24% to 29%: High-level starters and secondary scoring options.
  • 20%: The average usage rate (since there are 5 players on the court, 100% / 5 = 20%).
  • Below 15%: Role players, defensive specialists, or "3-and-D" players who don't create their own shots.

Example Calculation

Imagine a player with the following stats in a game:

  • 🏀 Player FGA: 20
  • 🏀 Player FTA: 10
  • 🏀 Player TOV: 4
  • ⏱️ Player MP: 35
  • 👥 Team FGA: 90
  • 👥 Team FTA: 25
  • 👥 Team TOV: 15
  • ⏱️ Team MP: 240

First, we calculate the player's possessions: 20 + (0.44 * 10) + 4 = 28.4.

Next, the team possessions: 90 + (0.44 * 25) + 15 = 116.

Applying the formula: 100 * (28.4 * (240 / 5)) / (35 * 116) = 33.5%. This player is operating at a very high usage level!

Why Usage Rate Matters in SEO and Betting

For fantasy basketball players and sports bettors, usage rate is a "leading indicator." If a high-usage star is injured, their 30% usage has to be distributed among the remaining players. Identifying which bench player will absorb that usage is the key to finding value in player props and daily fantasy lineups.
