Understanding Dynasty Trade Values
A dynasty trade calculator helps you determine if a trade is fair by calculating each player's long-term value based on their current production, age, position, and projected career arc. Unlike redraft calculators, dynasty values heavily weight youth and positional longevity.
Our calculator uses real-time Sleeper API data combined with age curve modeling to give you accurate dynasty valuations. Each player's historical value chart shows how their dynasty stock has trended over time, helping you make informed decisions.
Age Curves by Position
Different positions age differently in dynasty fantasy football. Understanding these curves is crucial for maximizing value:
Long Career Windows
- Quarterbacks: Peak ages 26-35, can produce into late 30s
- Wide Receivers: Peak ages 24-30, gradual decline after
Short Career Windows
- Running Backs: Peak ages 22-27, sharp decline after 28
- Tight Ends: Peak ages 25-30, late bloomers common
Superflex vs 1QB Leagues
The biggest difference in dynasty values comes from your league's QB settings:
Superflex Leagues
Elite QBs are the most valuable assets. Young franchise QBs like Josh Allen and Patrick Mahomes command premium values that exceed any other position.
- QB Value Multiplier: 2.0x
- Top assets: Elite young QBs, then elite young RBs
1QB Leagues
QBs have significantly reduced value since you only need one. Running backs and wide receivers become the premium dynasty assets.
- QB Value Multiplier: 1.0x
- Top assets: Elite young RBs and WRs
