NBA Player Efficiency Ratings 2025-26

NBA DFS Efficiency Value Rankings Explained

Our NBA efficiency value rankings help daily fantasy basketball players identify the best value plays on today's DraftKings and FanDuel main slates. By combining traditional efficiency metrics with salary data, you can find players who are producing well above their price tag — the key to building winning DFS lineups.

What is NBA Efficiency (EFF)?

NBA Efficiency (EFF) is an all-in-one statistic that measures a player's overall statistical contribution per game. The formula is: EFF = (PTS + AST + REB + STL + BLK + FGM + FTM) − (TO + FGA + FTA). It combines positive contributions — points, assists, rebounds, steals, blocks, field goals made, and free throws made — and subtracts negative ones: turnovers, missed field goals, and missed free throws. A higher EFF indicates a more productive overall performance.

DraftKings & FanDuel Salary

Each player's DFS salary is pulled from today's main slate on the selected site (DraftKings or FanDuel). Toggle between sites to compare pricing differences. Only players on the current main slate are shown, so you're always looking at actionable data for tonight's contests.

EFF Value (EFF VAL) — Finding NBA DFS Value Plays

EFF VAL = EFF ÷ (Salary ÷ $1,000). This is the core metric for identifying DFS value. It measures how much efficiency you get per $1,000 of salary. A player with a high EFF VAL is producing well above what their salary suggests — these are the value plays that let you fit premium stars elsewhere in your lineup. Compare EFF VAL across DraftKings and FanDuel to spot pricing inefficiencies between sites.

Help Value (HV) — Non-Scoring Contributions

HV = REB + AST + STL + BLK − TO. Help Value isolates a player's non-scoring contributions per game. In daily fantasy basketball, players who rack up rebounds, assists, steals, and blocks without turning the ball over provide a high fantasy floor. High HV players are especially valuable in cash games where consistency matters more than ceiling.

Productivity (PROD) — Per-Minute Efficiency

PROD = (PTS + HV) ÷ MIN. Productivity measures total contribution per minute played. A value of 1.00 means the player averages one positive stat (point, rebound, assist, steal, or block) per minute without a turnover. Players with high PROD ratings who are expected to see increased minutes — due to injuries, blowouts, or rotation changes — are prime DFS targets because their efficiency scales with opportunity.

How to Use These Rankings for NBA DFS

Sort by EFF VAL to find the best value plays relative to salary. Use the EFF window dropdown to check recent trends — a player with high L3 efficiency who was recently repriced lower is a strong value target. Filter by position to find value at each roster slot, and compare DraftKings vs FanDuel pricing to identify the best site-specific plays. Pair high EFF VAL value plays with premium stars to build balanced lineups that maximize your salary cap.

Understanding EFF Windows: L1, L3, L5, L10 & Season

We calculate efficiency across five time windows so you can identify trending players. L1 (last game) shows the most recent performance. L3 (last 3 games, the default) balances recency with sample size and is ideal for spotting hot streaks. L5 and L10 smooth out variance for a more stable picture. Season uses full-season averages and is best for identifying a player's true baseline. A player with a high L3 but lower Season EFF is on a hot streak worth targeting in DFS.
