Use this Redraft Trade Calculator to objectively assess the fairness and benefit of any trade proposal in your fantasy sports league. By factoring in projected points and the positional need of each team, you can quickly determine the net value exchange.
Redraft Trade Calculator
Redraft Trade Calculator Formula
Weighted Value Player B $(V_B) = PPB \times W_B$
Trade Differential Score (TDS) $= V_A – V_B$
Formula Sources: ESPN Fantasy Sports Analytics, Yahoo Fantasy Trade Principles
Variables
- PPA (Player A Projected Points): The estimated total points Player A will score for the remainder of the season.
- PPB (Player B Projected Points): The estimated total points Player B will score for the remainder of the season.
- $W_A$ (Team A Need Multiplier): A subjective multiplier (typically 0.5 to 1.5) representing how much Team A needs the position Player A plays. A higher need (e.g., replacing an injured starter) increases the player’s effective value.
- $W_B$ (Team B Need Multiplier): The multiplier applied for Team B’s need for Player B’s position.
- TDS (Trade Differential Score): The final score. A positive score means the trade is favorable to Team A (the team receiving Player A); a negative score means it is favorable to Team B.

What is Redraft Trade Calculator?
A Redraft Trade Calculator is a quantitative tool designed to help fantasy sports managers evaluate the fairness and advantage of a proposed trade in a redraft league (a league where the roster is fully drafted each season). It moves beyond simple point totals by incorporating contextual factors.
The primary purpose is to assign a weighted value to each player based on two core inputs: their raw projected scoring and the acquiring team’s positional roster need. For instance, receiving a star running back has a much higher weighted value for a team with no reliable running backs (high need multiplier) than it does for a team with two other star running backs (low need multiplier).
While the calculator provides an objective score (TDS), it is always recommended to use the result as a guideline, as intangibles like scheduling, injury risk, and player chemistry are not factored into the numerical output.
How to Calculate Redraft Trade Calculator (Example)
- Identify Inputs: Team A is trading Player B (200 Projected Points) for Player A (250 Projected Points). Team A has a high need for Player A’s position ($W_A = 1.3$). Team B has an average need for Player B’s position ($W_B = 1.0$).
- Calculate Player A’s Weighted Value ($V_A$): $V_A = 250 \times 1.3 = 325$ Weighted Points.
- Calculate Player B’s Weighted Value ($V_B$): $V_B = 200 \times 1.0 = 200$ Weighted Points.
- Determine Trade Differential Score (TDS): $TDS = V_A – V_B = 325 – 200 = 125$.
- Interpret Result: The positive score of 125 indicates a significant advantage for Team A (the team acquiring Player A), suggesting the trade is highly unbalanced in their favor.
Frequently Asked Questions (FAQ)
What is a good TDS score?
A TDS score close to zero (e.g., between -10 and +10) generally indicates a fair trade where both teams exchange equivalent value. A large positive score benefits the team receiving Player A, and a large negative score benefits the team receiving Player B.
How should I set the Positional Need Multiplier?
This is subjective, but common ranges are: Low Need (0.5-0.8), Average Need (0.9-1.1), High Need (1.2-1.5), Critical Need (1.6+). Use a higher multiplier if the player fills a starting lineup spot currently held by an empty or low-scoring player.
Does this calculator factor in draft capital?
No, this calculator is specifically for **redraft** leagues and focuses only on expected in-season value. For dynasty leagues, a different tool that factors in player age and future draft picks would be required.
What happens if the inputs are inconsistent?
The logic ensures that all four key values must be valid, non-negative numbers for the calculation to proceed. If invalid input is detected, an error message is displayed instead of a result.
