For recipes I do a little averaging --
I've done 23x 5.5 gallon recipes and 2x Apple Wines which gets me about 130 gallons of product. I assume each recipe averages out to $20 in materials (which is probably overestimating) so I spent $500 on materials. 130 gallons = 1040 US pints
I call $4/pint the retail price even though I've done DIPA/Imperial Stouts which would fetch $5+ / tulip glass in retail. So I've produced $4100+ of beer in the past year.
Total cost above is in the $1000+ range. Even if I double that and include all the fancy White Labs yeast, my inventory of hops & grain, 50 ft immersion chiller, pond pump, another 4 backup kegs, BIAB equipment, measurement devices, StarSan, Fermentation mini-fridge w. Johnson controller, etc. -- I still doubled or more my investment vs retail. I also used to go to bars for beer 2-3 times per week and spend another $100-$200 at the liquor store per month on craft beers. I still get craft brews from time-to-time but it's fairly insignificant in terms of price now.
I bought almost everything second hand and did everything DIY. I recently started buying base grains in bulk and milling my own grain which will bring the recipe prices down. I also lucked out getting the fridge, fryer, and burner kits for free. I also kept it simple with a single-vessel BIAB process.
Overall I feel like my hobby is also a sound investment. Now that I have all my gear already, all I'm buying month-to-month is the consumable goods (grain, hops, yeast, CO2, Star San, propane, and replacing the occasional melted/molded mesh bag). I also reuse bottles when I do bottle from time-to-time. I have no interest in upgrading anything at the moment or for the rest of the year. I will probably add a sight glass to the kettle but other than that, I like my gear and my process.
Now if I splurged and bought everything brand new, retail, and pre-assembled and went with a three-tier pump setup, I can imagine barely breaking even for the year.
=============================================
Dammit now I'm all curious about my expenses:
Mint.com says I've spent $1642 at Austin Homebrew Supply
I'll add another $250 for times I bought with cash. Call it $2000 for sanity's sake.
$2000 total expenses from AHS
$500-$700 for all the stuff I got off CraigsList or the HBT Classifieds
Not quite doubled my investment but it's still definitely a win.....
