Fantasy Trade Check

Dynasty Trade Calculator

Build a dynasty (superflex-based) trade and see each side's total value and fairness verdict, using the deepest real ADP sample this site has.

Values use FantasyFootballCalculator's 2-QB / superflex ADP sample -- the deepest real dynasty-relevant sample this site has (see "how it's calculated" below).

Verdict thresholds: within 10% of the larger side is "fair," up to 30% is a "slight edge," and anything beyond that is "lopsided." Values shown: Dynasty.

How it's calculated

Dynasty values on this site are built from Fantasy Football Calculator's 2-QB / superflex ADP sample -- the same value = round(10,000 × 0.97754^(ADP − 1)) curve used everywhere else on this site, applied to that sample's ranks. See the main Trade Calculator for the full formula writeup.

Worked example

Side A gives Justin Jefferson alone; Side B gives Chase Brown and Keenan Allen.

Justin Jefferson (Side A)5,540 pts
Chase Brown + Keenan Allen (Side B)5,704 pts
Verdictfair2.9% gap

A one-for-two trade that looks uneven in player count lands well within the 10% "fair" band once the actual values are added up -- one useful thing a trade calculator catches that eyeballing player names alone doesn't. (Threshold above 10% up to 30% is a "slight edge.") Source: Fantasy Football Calculator (fantasyfootballcalculator.com) ADP API, refreshed 2026-09-17.

Frequently Asked Questions

Why does dynasty mode use superflex/2-QB values instead of its own dynasty ADP?

Fantasy Football Calculator does publish a dedicated dynasty-ADP endpoint, but its real sample only covers about 19 players this early in a season -- far too shallow to rank a full trade-calculator pool from, and it mixes in defenses and kickers ahead of real dynasty assets. Superflex/2-QB ADP is the deepest real sample available (roughly 200 players), and most dynasty leagues run superflex anyway, so it's the more honest base for a full dynasty pool. See the About page.

Does dynasty factor in a player's age?

Not directly -- there's no age field in the real ADP data this site pulls. The market (real drafters setting ADP) already prices in age and opportunity indirectly through how early or late they draft a player, but this site doesn't apply a separate age multiplier on top of that. Treat dynasty values here as a redraft-market-informed starting point, not a dedicated dynasty model.

Does this include future draft picks?

Not yet. There's no real, public data source for future rookie-pick trade value that this site could use the same way it uses real player ADP, so pick-for-player trades aren't modeled here -- only player-for-player. That's a real limitation, stated plainly rather than filled in with a guess.

How do I evaluate a straight-up dynasty keeper decision?

Use the Keeper Value Calculator -- it compares a player's dynasty or redraft value directly against what draft pick you'd give up to keep them, on the same value scale.

These are estimates, not advice; your league's settings decide what a player, pick or waiver claim is really worth to your team. See the Terms for how values are sourced and where this tool's judgment can be wrong.
