Shoot, I got excited yesterday when I saw that ~1500 number. I remember thinking "wow thats more than I think I'm making...

for May 2013: $5660 - $2377.23 - $1808 = ~$1500, is that right?

I was wrong. This is incorrect. the 2377.23 is the sales - the cost of reports, so its

    +$5660   Total Sales
    -3282.77 Cost of reports and stripe transaction fees
    -1808.08 Trailing average monthly fixed costs
    ---------------
    ~570     Leftover to the business

Which makes the "breakeven" calculation in another comment even more dismal, at something like 180 months assuming no growth. Yay!

However, the real growth trajectory is probably between 0 and the trailing history that seems to be adding about 600/mo.

If I linearly add 600/mo to my gross profits, the breakeven will happen between about 17 months from now.

I have no delusions that i have any ability to predict the growth trajectory though, so for now my plan is "keep doing anything I can to grow it as fast as I can".
