Question 1

How do you value keepers in fantasy football?

Accepted Answer

To value a keeper in fantasy football, compare the draft round cost to keep a player against their current Average Draft Position (ADP). If you can keep a player in round 8 but their ADP is round 4, you gain 4 rounds of value — that's a strong keep. If their ADP is round 9, you lose value and should let them go. KeeperCalc automates this calculation for every player on your roster using live ADP from Yahoo, ESPN, Sleeper, and FantasyPros.

Question 2

What is a keeper ROI calculator?

Accepted Answer

A keeper ROI calculator compares the cost to keep a player (measured in draft rounds) against that player's current Average Draft Position (ADP). The difference — called Rounds of Value or keeper ROI — tells you how much draft capital you gain or lose by keeping each player. KeeperCalc is a free keeper ROI calculator that connects directly to your Yahoo, ESPN, or Sleeper league and runs this analysis automatically for every player on your roster.

Question 3

How do you calculate fantasy football keeper trade value?

Accepted Answer

Fantasy football keeper trade value is calculated by comparing the keeper ROI of the players involved in a trade. A player with a high positive ROI (cheap to keep relative to their ADP) is more valuable than a player with low or negative ROI. When evaluating a keeper trade, you need to weigh both the players' production and their keeper costs going forward. KeeperCalc's Trade Analyzer (Edge tier) does this automatically — it shows you the keeper value on both sides of any trade so you can see exactly who wins and loses.

Question 4

What is the best fantasy football keeper trade calculator?

Accepted Answer

KeeperCalc is a fantasy football keeper trade calculator that factors in live ADP and your actual keeper costs — not just player rankings. Unlike generic trade value charts, KeeperCalc knows your specific keeper rules and calculates the real ROI of keeping each player in your league. The Edge tier includes a Trade Analyzer that compares keeper value on both sides of any proposed trade.
