Your Sleeper league’s rules matter more than the platform name on the offer. Start with the free calculator and match the league’s quarterback slots, reception scoring, tight end premium, and team count. Where league import is available, use the roster helper to select players already on each team, then review the resulting settings before calculating. The manual tool always remains usable. This is an independent dynasty calculator, not an official Sleeper valuation service, and a public league import does not give permission to submit or accept trades.
Import helps select assets; it does not set a market price
A league roster can identify who owns a player. It does not establish that player’s trade value. Verify any imported scoring settings against the league rules and keep unusual bonuses in mind.
Example: build a league-specific offer
Choose two rosters, select a player from each, and add a future pick manually if needed. Compare the same offer in the calculator and use the share link for discussion. No trade is submitted to your league.
Availability and platform terms
Sleeper documents its API as read-only and distinguishes non-commercial from commercial use. Import availability depends on the service configuration and applicable permissions. Manual player search and pick selection do not require an import.
Questions before you trade?
Do I need my Sleeper password?
No. Do not enter a Sleeper password into this calculator. Any supported public import uses a league identifier rather than account credentials.
Will the calculator submit a trade on Sleeper?
No. It only helps compare packages; it cannot accept or submit a league transaction.
Can I calculate without importing a league?
Yes. Guests can search players, add rookie picks, change settings, and share a comparison manually.
