Trade Simulator

Pick a team on each side, click or drag the players going each way, and read the balance as you build the deal. Every number is the one shown on Trade Value: projected WAR priced at $/WAR, discounted 10% a year on wins and salary alike, over the years the club controls the player. Any N-for-M structure works.

Side A

Side B

How the numbers are built: projected WAR × $/WAR ($8M in 2027, +3% a year, relievers 35% lower, capped star premium) × NPV (10% a year) minus the salary owed over the control years; the TV score weights downside / base / upside outcomes 30 / 40 / 30 and scales by confidence (bust rate × distance to debut). NTC marks a full no-trade clause. Roster fit counts only players currently in the majors; each position shows the top projected WAR on that club before and after the deal (pitchers: the five best arms combined).
