Keeper League Trade Calculator
Keeper trades combine this season's production with future surplus. Select a player, the round you must spend, and how long the contract lasts to estimate the value between redraft and dynasty—not just bracket it manually.
Player values by Dynasty Dealer.
The keeper-value rule of thumb
Value each asset as: redraft value + (dynasty value − redraft value) × keep-ability. The estimator infers the player's current redraft round from his overall market rank and your league size. A multi-year player kept later than that market round receives more of the dynasty premium; an expensive one-year rental stays close to redraft value. The calculation is shown as an estimate because league-specific keeper inflation still matters.

- How do I value players in a keeper league?
- Keeper leagues sit between redraft and dynasty: players you can keep cheaply for multiple years should be valued closer to dynasty prices, while rentals you'll lose after this season are pure redraft assets. Analyze with both toggles and treat the truth as somewhere in between, weighted by how long (and how cheaply) each player can be kept.
- Which value set should I pick in the calculator?
- Start with Redraft for this-season fairness. If the player being traded is a long-term keep at a good cost (a cheap late-round keeper, a young breakout), re-run it on Dynasty — if the trade wins both ways, it's a clear accept.
- How does keeper cost change a player's value?
- A player kept for a late-round pick is worth more than his raw value, because you also save the draft capital. As his keeper cost approaches his real draft slot, that surplus disappears — and so should the premium you pay in trades.
- Are draft picks tradeable in keeper leagues?
- Often yes — and the dynasty value set includes rookie picks so you can price them. Values updated Aug 30, 2026.
