The dynasty fantasy football trade calculator that doesn't just tell you if a trade is "fair" — it tells you WHY, with four data sources, roster-spot pricing, and shareable trade cards for your league chat.
Every player gets a Tradyr Value (TV) score on a 0-1000 scale that blends:
Confidence-weighted, position-normalised, then age-adjusted. No single source dominates — you get a four-way consensus rather than one site's opinion.
Most trade calculators grade a 3-for-1 as fair if the raw values match. In reality, dynasty roster spots are scarce — a single elite player is worth more than three mid-tier players of equivalent total value. Tradyr's Roster Spot Premium toggle credits the consolidating side ~75 points per roster spot freed. Toggle it on for multi-piece trades to get the honest grade.
Every evaluation generates a shareable URL and a downloadable trade card image with both sides, values, fairness label, and a QR code back to Tradyr. Paste in your league chat and end the debate.
Is the dynasty trade calculator free?
Yes — Tradyr's trade calculator is 100% free with no signup, no ads, and no paywall. It supports unlimited trades, all league formats (1QB / Superflex / TE Premium), and includes 2026-2028 rookie draft picks.
How does Tradyr's trade calculator compare to KeepTradeCut?
KTC uses a single community-voted value per player. Tradyr blends KTC + FantasyCalc + DynastyProcess + real dynasty trade data (300,000+ trades from public Sleeper leagues) into a composite Tradyr Value. You get four data sources instead of one, plus a Roster Spot Premium toggle that prices multi-piece consolidation trades correctly.
Does the trade calculator support draft picks?
Yes. 2026, 2027, and 2028 rookie picks (rounds 1-4) are fully valued for both 1QB and Superflex formats. Rookie-class strength adjusts pick values automatically — 2026 1.01s in a stronger class price higher than 2027 1.01s in a weaker class.
What is the Roster Spot Premium?
A toggle that credits the side of a trade sending fewer pieces for a "consolidation" premium. In dynasty, four Player Bs are usually worse than one Player A of equivalent total value because roster spots are scarce. When enabled, the consolidating side gets ~75 points per roster spot freed.
Can I share the trade evaluation?
Yes — every trade generates a shareable link and downloadable PNG image with both sides, values, fairness label, and a QR code back to Tradyr. Perfect for league chat debates.
Does it work for redraft or best-ball?
The calculator is dynasty-first, but redraft and best-ball rankings are also available. For best-ball trade grading during the season, use the Sleeper subdomain analyzer at sleeper.tradyr.app.
