Extension Simulator

Model new deals before they're signed. Build the contract, see every season's cap hit, the exit cost, what it does to the team's headroom — and whether the money matches what the model says the player is worth.
Step 1

Pick a player

Nothing picked yet. Search for a player in the league selected above — the builder changes to that league’s contract rules.
How to read this

Sources, formulas and basis

Shared rules

  • Every number is computed in your browser from the terms you type. Nothing is saved and nothing is written back to the database.
  • The new deal is assumed to replace the current contract from its start season onward. Seasons before the start season keep the existing cap hits.
  • Verdict tiers are the same ones the trade machines use: within 10% is even, 10–25% is one side ahead, more than 25% is lopsided.
  • Rule breaks are shown, never blocked — a red banner names each violation and the deal still computes.
  • Money is nominal dollars of the season shown unless a line says otherwise. Projected league limits are labelled PROJ.
