Most of my gear is second hand, which has huge savings attached to it. And let me pay it all off in savings in less than a year.
5 gal pot, 60 bombers, siphon, 3 buckets with airlocks, full bottle of starsan, brushes, spoon, 300 caps, pump bottle sanitizer (can't remember the name): $100
6 better bottles: $30
7 gal kettle: $50 (can with a siphon, 15kg of barley, 6oz Galaxy, 12oz El Dorado thrown in)
Corona mill + drill: 45
60 bombers: $20
66 bombers + 24 swing top 1L: free
So my total gear cost was 245, plus expendable items (caps, starsan, brew bags etc) per batch.
For the beer in the other hand, it costs roughly $6.50 average for a bomber here, and my set up gets me 30 of them, which is $195 if I bought them, plus tax and bottle deposit.
But for brewing it costs me $12 grain, $4 hops, plus whatever fruit or other adjuncts/spices I use (say average of $10 because I like my fruit beers), so roughly $26 a batch since I buy my grain and hops bulk, and reuse the hell out of my yeast. Which gives me a saving of $169 a batch, which if I am regularly drinking is a monthly saving, so $2,028.
Factor in gas, which my two year credit ran out on 4 months ago (got to love when a utility company royally screws up and compensates you), I easily break even making delicious beer.
All the above being said though, I would probably only be having a beer or two a week if I didn't brew, which would be about the same amount lol.
