Play for Keeps

Trade Calculator

Prices a proposed trade the way the by-laws do: weighted side values, the Trade Differential, the next-year auction-budget penalty, and whether the trade is legal at all.

The calculator is for league managers.

How the math works

  • Multi-player sides: most valuable player at face value, second at ¾, third at ½, all subsequent at ¼.
  • The Trade Differential is the gap between the two sides, rounded to the nearest point.
  • Differential of $10 or more: the amount above $10 is split evenly and subtracted from both managers' next-year auction budgets (odd amounts round up).
  • A Differential over 50 points makes the trade illegal.
  • Values: FantasyCalc (half-PPR, 10-team), normalized to the league's CBS-style scale where the top player ≈ 47. Refreshed hourly. Players not on the ~200-player chart count as $0.
