Sleeper Stats

Sleeper trade calculator · redraft and dynasty

The trade calculator that knows your league.

Other trade analyzers price players in a vacuum. This one opens your Sleeper league, reads both rosters, your scoring and your lineup slots, and tells you two things: what the market says, and what the trade does to each starting lineup.

In the Sleeper app: open the league, tap the gear, then General. The league ID is at the bottom.

How the grading works

Market value

Every player and pick is priced from FantasyCalc, which builds its values from thousands of real trades. The table is chosen for your league: redraft or dynasty, PPR, superflex, team count. Add up what each side gets, take off what a side has to cut to fit the roster, and you have the verdict: even within 5%, a slight edge within 15%, a win beyond that. Twelve third-round picks are not a stud once they have to be rostered.

Roster fit

Value is not the whole story. Each roster is sorted into your league’s actual slots, before and after, so you can see who starts, who leaves the lineup, and who comes in only to sit. It is shown next to the verdict, never blended into it, so the two can disagree and you can decide.

Picks, projected

Dynasty and keeper leagues trade picks. Each team’s picks come from Sleeper, trades included, and next year’s are priced as Early, Mid or Late from the current standings: a last-place team’s first is worth more than a contender’s.

Questions

Does it work for my league’s scoring?
The market table matches your points per reception and whether you start two quarterbacks. Lineup fit uses your exact slots, FLEX and SUPER_FLEX included. Points per game are what each player actually scored in your league this season.
Why is my kicker unranked?
The market does not price kickers, defenses or IDP, so they count as zero. You can still put them in a trade, and they still fill a lineup slot.
Can I send the verdict to the league?
Share saves the trade as graded that day and gives you a link with a preview card. The link keeps saying what it said, even after values move. The other manager can open it and counter from there.
Do I need an account?
No. Paste a league link and go. If you have told Sleeper Stats which manager you are, your leagues are listed above and your team is picked for you.
Three-team trades? Other sports?
Two teams, football only, for now.
