In order to account for keeper inflation, you will first need to make sure to input your keeper salary costs in Draft Wizard (My Leagues > Edit under Keepers > fill out keeper salary information).
Once that is done, go to the Auction Calculator, then Select League in the top right. Select your league settings and then click on the Save as Cheat Sheet button.
This cheat sheet excludes keepers and increases the recommended bids of available players to account for value inflation. Use this cheat sheet in mock auction drafts and in the Auction Draft Assistant in order to account for keepers.
You can also account for player value inflation during the draft (adjusting player values based on remaining auction dollars) by clicking on the Auction Inflation checkbox when using the Auction Draft Assistant or the Auction Simulator.
