It's really not that bad, especially if you use Excel. Once you have you have your VBD point values, determine the production pool by summing the value of each starter. For example, top 12 QB + top 24 RB + top 24 WR + etc, and we'll say our total is 4,300 points.
For the monies, it is cap ($250) minus minimum bid ($1) multiplied by the number of teams in the league (12):
($250 - $1) / 12 = $2988.
Divide the disposable cash ($2988) by the available points (4300):
$2988 / 4300 = .70
Peyton's VBD value is 90.1 so his projected dollar worth is:
(90.1 * .70) + $1 = $64.
The +1 is adding the minimum bid back into the value. If you have a player with negative points than you probably won't want to draft him but for completeness his value (not necessarily worth) would be $1. There are more advanced models that apply the dollars on a per category basis which is necessary for fantasy baseball but overkill for fantasy football IMHO.
