How does the dynasty trade calculator work?

Our dynasty trade calculator uses live Sleeper API data to calculate player values based on age, position, production, and long-term potential. It factors in dynasty-specific metrics like years of elite production remaining and positional scarcity.

What league formats does the dynasty calculator support?

The dynasty calculator supports Superflex (2QB), 1QB, PPR, Half-PPR, and Standard scoring formats. You can toggle between formats to see how dynasty values change based on your league settings.

How are dynasty trade values calculated?

Dynasty values are calculated using a combination of current production, age curve projections, positional scarcity, and draft capital value. Young players at premium positions receive higher values due to their longer windows of production.

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
