Dynasty trade calculator for your Sleeper league
A dynasty trade calculator puts a number on every player and pick so two sides of a trade can be compared. FleeceRoom does that, and then checks the same trade against your actual league: your roster, your league-mates' rosters, your scoring and your lineup. It's free, it needs no sign-in, and it works with any Sleeper dynasty league of this season with 8 to 16 teams, 1QB or Superflex.
Open FleeceRoom and paste your league
Three views of every trade
A plain calculator gives one verdict. FleeceRoom gives three, and every number reads + = good for you:
- Calculator (FantasyCalc): both sides on FantasyCalc's dynasty values, which is what most league-mates check before they accept.
- Their overpay: what the other team gives over what it gets, in that team's own values. A contender values points this season; a rebuilding team values youth and picks.
- Yours: what you gain in your own team's values, after any roster cuts the trade forces.
A trade can be even on the calculator and still clearly good for both teams, because they want different things. That is the trade FleeceRoom looks for.
Two players for one: the value adjustment
Two good players rarely equal one star, even when the totals match: the star fills one roster spot and scores more in it. FleeceRoom compares uneven trades with a value adjustment for the side getting the best player. The adjustment only applies when the number of pieces differs, and the difference shows in big type, for example "You +240", or "Even" when the two sides are within 2% of each other.
Superflex or 1QB
The number of quarterbacks a team can start changes everything. FleeceRoom reads your league's lineup from Sleeper and asks FantasyCalc for values in your format (Superflex or 1QB, your number of teams, your PPR setting). It also measures how many points each player scores over the replacement-level player in your league, so a quarterback in a 1QB league isn't priced like one in Superflex. More on that on the Superflex trade values page.
Points this season, and title odds
For a contender, a trade is about the lineup. FleeceRoom builds each team's best lineup every week from Sleeper's projections, counting injuries and byes, and shows the lineup points a week each side gains or loses. For any trade it can replay 10,000 simulated seasons with and without the trade, so you see every team's playoff and title odds move, not just yours.
Rookie picks
Picks are valued by where they're likely to land. FleeceRoom projects each team's draft slot from the same simulated seasons and prices the pick from FantasyCalc's values for that slot, so a pick from the last-place team counts as an early first.
From a number to an offer
The calculator is only the start. The Trade page turns it into offers: pick a player to sell and see one fair package from every other team, or pick a player you want and see what his team would take, including a two-step path through a third team when that's cheaper. Trade ideas does the searching for you across the whole league.
Frequently asked questions
Is FleeceRoom's dynasty trade calculator free?
Yes. There's no account, no subscription and no ads. Your settings stay in your browser.
Where do the values come from?
FantasyCalc's dynasty values, in your league's format. You can also paste KeepTradeCut values in Settings to see them beside FantasyCalc's; FleeceRoom never fetches anything from KeepTradeCut itself.
Does it work for 1QB leagues?
Yes. FleeceRoom reads the lineup from Sleeper and uses 1QB values for a 1QB league and Superflex values for a Superflex league.
Does FleeceRoom change anything in my Sleeper league?
No. It only reads public league data from Sleeper. You send trades in Sleeper yourself.
