I don't buy anything but hops in bulk and almost any style is going to cost me under $30 a batch to make and some styles closer to $20. Craft beer costs around $18+ a 12 pack (with deposit) from the big players up here (Deschutes, Hop Valley, Ninkasi, Sierra Nevada, etc.)
If you want to drink beers from breweries that only release bombers that same amount could easily be $30+
My equipment costs are pretty reasonable. I have a nice Spike kettle, a nice burner with leg extensions, I BIAB, and have 5 kegs with the ability to have 4 on tap, a fermentation chamber, etc. Needless to say it's a pretty advanced setup and much more than anyone needs for making beer and all of that cost me probably no more than $1,000.
From my calculations I easily save $15 a gallon compared to buying 12 packs and bombers, even including costs like propane, cleaners, sanitizer, and CO2.
I don't brew beer to save money, I brew beer because I really enjoy it. It's a neat skill to have and a hobby that can be enjoyed by friends and family. However, I think I've definitely gotten to the point where I've broken even which is just an added perk.
