About the dynasty trade calculator
Roster Audit ingests thousands of real dynasty trades every day from Sleeper leagues and feeds them into our market valuation engine. Each trade nudges player and pick ratings toward equilibrium.
Recent trades matter more, clean 1-for-1 deals carry the strongest signal, and outlier trades are automatically down-weighted. Values update daily to reflect the live dynasty market.
Consolidation adjustments on other calculators are a bandaid for values that don't come from real trades. Since our values are built entirely from actual completed trades, the market's consolidation premium is already priced in.
The engine sees what managers actually pay to move from two good players to one great one, and the grades reflect that.
Instead of manually adding each player to the calculator, just screenshot the trade offer in Sleeper and upload it. Our system identifies every player and pick in the image and grades the deal using our real-trade values.
Same accuracy as the main calculator, just faster.
Syncing your Sleeper league gives you roster-locked trading, meaning you pick a leaguemate and build trades from what each of you actually owns.
On top of that, you unlock a full trade intelligence report covering lineup impact, positional needs, age and cliff risk analysis, and a verdict that accounts for your specific team context.
The trade intelligence report is a detailed breakdown that appears below the grade when you have your Sleeper league connected. It covers how the trade changes your starting lineup, which positions get stronger or weaker, whether you're acquiring aging players near a cliff, and how the deal fits your team's competitive window.
It's the difference between knowing a trade is fair and knowing if it's right for your team.
The calculator supports Superflex, 1QB, TE premium, and all PPR scoring formats across all league sizes. Sync your Sleeper league and values adjust automatically to your settings, or pick your format manually from the dropdown.
