A dynasty trade calculator that knows your league
Most calculators add up two columns from a default league. This one reads your Sleeper league first: superflex, TE premium, scoring, lineup slots and league size are applied before you tick a player.
Then it answers the questions the total doesn’t: what the deal does to both lineups, what it costs in roster spots, and whether the owner across from you has ever paid that kind of price.
More than two columns
- Values for your format
- Every player is repriced for your league in two steps: how many starters each position needs there, and how your league scores each player. Superflex and TE premium come from Sleeper; there is nothing to set.
- Picks by draft slot
- Next year’s picks are priced Early, Mid or Late from the projected draft order; later years as mid-round picks. Picks never take a roster spot.
- The roster spot
- Taking back more players than you send forces cuts, and those are taken off the net. Sending more frees a spot, and the best free agent you could add is shown beside it.
- Two-for-ones, priced honestly
- An uneven trade gets a consolidation line beside the plain net: a pair priced as a package, so two mid-tier players don’t “pay” for a star on paper.
- Both lineups, and the playoffs
- The change to your best lineup and your team’s age, position-group ranks before and after, and both teams’ playoff odds before and after the trade.
- Would they say yes?
- The verdict says whether your partner is likely to accept and why, counting how they have priced players in their own trades.
- Balance it, or paste an offer
- A lopsided deal shows the three players or picks that square it. Got an offer on Sleeper? Paste its text and both sides fill in, with a counter-offer.
- Three-team trades
- Pick three teams, send each player or pick where it goes, and see every team’s value in and out with a grade.

Questions
Is there a dynasty trade calculator for superflex leagues?
Yes. Dynasty Seer’s Trade Calculator reads whether your Sleeper league is superflex and reprices every quarterback, and everyone else, for it. The same goes for TE premium and your scoring.
Does it include draft picks?
Yes. Rookie picks are part of every trade: next year’s priced Early, Mid or Late from the projected draft order, later years as mid-round picks.
Where do the trade values come from?
From Dynasty Dealer, which builds them from real Sleeper trades. Dynasty Seer then reprices them for your league’s scoring, lineup slots and number of teams.
