Roster Positional Scarcity Calculator
Determine which positions are most scarce in your fantasy league by calculating the scarcity score — the ratio of starter production to replacement-level production. Higher scores indicate greater positional scarcity and more draft value.
Results will appear here.
Formulas Used
Total Starter Slots = Number of Teams × Starters Per Team
Scarcity Ratio = Average Starter Points ÷ Replacement Level Points
Supply Scarcity Index = Total Starter Slots ÷ Total Viable Players
(ranges 0–1; values near 1 indicate very tight supply)
VORP = (Average Starter Points − Replacement Level Points) × Scoring Multiplier
Adjusted VORP = VORP × Supply Scarcity Index
Positional Scarcity Score (PSS) = Scarcity Ratio × Supply Scarcity Index × 100
Surplus Players = Total Viable Players − Total Starter Slots
Assumptions & References
- Replacement level is defined as the average production of the next tier of players beyond the last starter drafted — the best available player on the waiver wire.
- The Scarcity Ratio captures the production drop-off: a ratio of 1.6 means starters average 60% more points than replacements.
- The Supply Scarcity Index captures how many viable players exist relative to how many are needed as starters league-wide. A value of 0.80 means 80% of viable players will be drafted as starters.
- PSS combines both dimensions: production drop-off and supply tightness. It is a composite index, not a raw point value.
- Scoring multipliers: Standard = 1.0×, Half-PPR = 1.5×, Full PPR = 2.0× — applied to VORP to reflect how scoring format amplifies positional value differences.
- VORP methodology is widely used in fantasy sports analysis; see Fantasy Pros, Rotoviz, and academic sports analytics literature (e.g., Beuoy, 2014).
- PSS tiers (Extreme ≥80, High ≥55, Moderate ≥35, Low ≥20, Abundant <20) are calibrated for standard 12-team leagues and should be interpreted relatively across positions in the same league.
- This calculator evaluates a single position at a time. Compare PSS across all positions in your league to prioritize draft strategy.
