Is this trade calculator free?

Yes. It runs in your browser with no account, email or payment required.

How does it decide who wins the trade?

It weighs total value and weekly projected points on each side, then adjusts for roster fit — whether the incoming players fill thin spots or add depth you cannot start.

Does it work for Sleeper, ESPN, Yahoo and CBS?

Yes. You supply the players and projections, so the verdict applies to any platform and scoring format, including PPR and superflex.

How to read the verdict

Use rest-of-season weekly projections on both sides — consistency matters more than the source.
A close value gap with a positive points swing usually means the trade upgrades your starting lineup.
Two-for-one deals look great on value but thin your bench; check the roster fit note before you accept.

Also try the trade value chart, waiver wire pickups and the draft grader.
