Trade Calculator

Build a trade and see value, roster-spot cost, positional impact and an AI verdict before you send it.

How to use it

  • Pick a trade partner from the chips.
  • Tick players and draft picks on both sides. On a phone, the “You give / You get” switch above the rosters shows one side at a time, with how many you’ve ticked and their value.
  • Once both sides have something, each roster folds to what’s in the trade so the verdict sits right below; Show full roster opens it again, and the search box finds anyone either way.
  • Read the value totals, then "Get the AI verdict" if you want one.
  • The trade stays while you look around: open a player’s page or another tab of the app and come back (or reload) and it’s still there, in this browser tab. “Start over” next to the partners clears it.

What it shows

  • The Value verdict card, right under the rosters (See the verdict in the trade bar jumps to it), gathers the answer: the net value (the same number as the trade bar), the value grade, whether your partner is likely to say yes and why (a deal that’s fair at market but a clear loss by how they’ve priced players in their own trades counts against it), the roster-spot note and the change to your best lineup and playoff odds. The grade and the yes read wait until both sides have something. The detailed cards follow it.
  • Net value for both sides, draft picks included. 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.
  • Roster-spot cost: taking back more players than you send forces cuts, and those are taken off the net. Sending more frees a spot: the best free agent you could add is shown next to the net but not added to it, because a spare spot rarely brings back that much.
  • Position-group totals and league ranks before and after.
  • The effect on this week’s best lineup and on your team’s age.
  • Your playoff and title odds, and your partner’s playoff odds, before and after the trade.
  • Balance this trade: when the deal is lopsided, the three players or picks that square it, one tap to add. Tick the player you want and it becomes a trade finder: offers lean toward the positions (or picks) that owner usually trades for, with the reason shown.
  • Three-team trade (the link next to Paste an offer): pick three teams, then point at a player or pick (tap him on a phone) and send him to one of the other two with the “To …” button that appears (each pick shows its projected slot and where it came from), and see every team’s value in and out with a grade, plus a copy for the league chat.
  • About your partner: once you pick one, a row above the rosters holds the strongest three angles from their scouting report (what they need right now, what they shop for, how they deal…) and how they trade. It is open while the trade is empty and folds away once you tick something; tap it to open it again, tap an angle for the numbers and the tip, or open the full report.
  • Paste an offer: got an offer on Sleeper? Paste its text (or a message) and the names and picks are read into both sides with the partner picked, so you see the grade, the roster-spot cost and a counter-offer at once. Full names, “J. Allen”, a last name or a distinctive first name on its own (“Chase for Jefferson”, “Bijan”) when only one player in the league has it, and common tags (CMC, JSN, ARSB, MHJ, BTJ, KW3, Hollywood Brown) all work. Picks both sides own are left for you to tick.
  • Copy offer: once both sides have something, a message ready to paste into a DM. It leads with what this owner has traded for before: a young player for someone who buys youth, a producer’s points for someone who buys veterans, the picks for a pick collector, or the value edge when the deal favours them. On a computer, hover the button to see which.
  • Trade fatigue: every Copy offer or Copy link counts as a pitch to that owner (in this browser). Pick them again and a note says how often you’ve pitched them in the last 30 days and whether a trade followed, so you don’t wear a partner out.
  • Your offers, a card below the calculator from your first copy on: every trade you copy with Copy offer or Copy link is saved there (per league, in this browser and on your account when signed in; copying the offer and then the link is one offer). Each row shows the partner, what you give and get, when you sent it, its status and its value for you then and now, on the same league values the calculator uses. It reads Accepted once a trade with that partner goes through after you sent it with those players and picks (or “a version of it went through” when most of them moved), Expired after 14 days without one, and Pending until then; Sleeper doesn’t share declined offers, so mark those yourself. Reopen in calculator loads the trade again; Remove deletes it. Pending offers come first.
  • Copy link: a link to this exact trade. Your trade partner opens it from their side; anyone else in the league sees it from yours. Pasted into a chat, it previews as the trade: who gets what, who wins on raw value, and a card image.
  • Counter this offer: enter an offer you received (both sides) and, when you’re the one overpaying, you get a value grade and three counters (ask them to add one of theirs, take one of yours out, or swap one of yours for a cheaper player at the same position), likeliest first, each with Apply and a copyable reply.
