Since everybody knows that linebreeding is the only way to get good dogs, I'll give you the formula I came up with.
First you need to know your inbreeding coefficient( IC ), it can be found here.

If you have an IC of 21%, take $1,000.00 x .21, and sell the pups for $210.00
If you have an IC of 0%, then $1,000.00 x 0, is $0.00, give the pups away.
Now here is where it gets tricky. If there is any W. Ben in the pedigree, you MUST account for his percentage.
You take the IC of say... 21% x $2,000.00 ( it's $2,000.00 because let's face it, Ben dogs are just better....) Giving you $420.00 per pup, you then have an markup of Ben's percentage. Let's say the pups are 38% Ben, so you take $420.00 x 1.38, now you get $579.60 per pup. If you furnish papers and guarantees you get a 30% bonus, bringing you to $753.48...
Based on watching the dog trade for a number of years, that's the best formula I have come up with to value BMC pups.
