I started a few month before the end of the year. I keep track of all expenses, credits, and milage in a spreadsheet. I was pretty happy with the "revenue" number (total credits from selling scrap/items before deductions).

I was pretty happy with my profits before milage deduction, but after entering my total milage driven for curbco scrap, it turns out everything I did last year my actual "on paper" profit for 2019 was $-21 (notice the negative). If it wouldn't have been for some particularly good buy/sell deals I did (not curbco), that number would have been MUCH more negative. I really like the hunt and the concept of curbco shopping (finding cool stuff, keeping stuff out of the trash/landfill, etc), but it is certainly not at all a profitable venture in my experience. It is a lot of fun to find the treasures on the curb and flip them quick for a good bit of money, but even including those, I still do not think curbco can be super profitable. I think I will keep doing it for now because I like it, but maybe not as often (currently do 3 days a week, might cut down to 1 or 2 just the days of the best neighborhoods). For 2020, going to try to focus more on trying to get a regular client/source for scrap instead of driving and looking on the curb for it.
