I did a little digging and found out that the annual cost for some one like me would be $100 but it would cost more for people in large companies. This isn't exactly outrageous but got me to wondering how many other packages might not be free. I searched online but didn't find much.

Are you talking about CRAN packages?
If so, looking into the license information of the repository shows 
which have standard licenses such as GPL and which licenses are special. 
Just take a look, e.g. starting with

download.file("http://cran.R-project.org/web/packages/packages.rds", 
"packages.rds", mode="wb")
x <- .readRDS("packages.rds")
x <- x[!duplicated(x[,1]),]
table(x[,"License"])
