How do you calculate loss after primary?

My beer usually goes straight from primary to keg which is why I can't really measure it. I don't want to contiaminate my beer by measuring out 2L pitchers either.

My partial-mash brewing process utilizes hop bags, and my beer is strained before going into the primary. So really, I feel the only loss is the beer caught in the yeast slurry which is maybe 1-1.5 inches high. Anyone want to guess how much I'm losing?

I don't worry about primary loss too much because it is rather insignificant.

That totally depends. I brewed a Founder's Breakfast stout and lost almost a gallon to trub. Depends on the beer. If you wanted to estimate you could measure the diameter of the fermenter, the height of the trub, and use that to calculate roughly the loss.

I get about half a gallon but up to a full gallon (rare rare rare) of trub loss.

Almost always, I get about 1/4 gallon of trub loss from fermenter to bottles/keg. I rack only clear beer from the fermenter, but I do give it time to sit and settle.
