I'm not sure why I'm responding other than I thought the post was a little discouraging to people getting into breeding ball python morphs. Of course the number of babies produces and prices can vary greatly but this is how I try to calculate potential profits. My girlfriend hates it.....
One if I only had a 57% (20 out of 35) breeding success I would be pretty upset, I would say more like 70% to 80% so out of 35 females more like 25 to 28 gravid females as long as the weight is good and they are cycled properly. But even going with your calculations of 100 babies 50 norms 50 pastels equal numbers of males and females. Unless you need to move the normals out immediately you should make more than $625. Go with the 25 males 25 females, you feed them 8 times or so around $160 in mice you should easily get $20 for the males and 35 for the females so $1215 being conservative. Look at the classifieds for 2004 normals for the current prices, and if you set up at shows you can usually get more.
For the pastels even if we go with $1500 a pair wholesale that would be $38,715 minus the $20,000 investment you are left with $18,715. I did a quick calculations on electrical usage for a rack and you figure for 10 adult females you are using around 200 watts full power (11" x 12" Flex Watt per box) so 1752 Kw/h per year at the rates here that would be $144.89 per rack times 4 racks. Figuring the same racks for males. So $579.56 a year, the yearling racks for 100 ball pythons around $280 a year so even if we say $1000 per year for electricity now you are down to $17,715. If you are good with your hand you can build a nice adult rack that holds 5 for around $80 plus boxes, so say $1500 for all the racks now you are at $16,215. Take off another $1500 for heat tape, thermostats, water bowls etc, so we are at $14,715. Now for feeding, I don't see a reason to breed your own if you have a rodent breeder close or can pick up at a local swap. I have around 70 snake in my collection mostly ball pythons and dealt with another 281 babies this year most of which were farm hatched baby balls. Anyway, year to date I have spent around $1600 in food and I'm sure I had some frozen from last year so maybe a little more. Of course we are not talking about those numbers so say $1500, now it's at $13,215 this looks a little better than $5000.
BUT... There are a few important things were left out of the previous post, with these figures after the first year you would have paid off your initial investment, the racks, and the accessories so the following year you have food time and electricity. So taking the $38,715 or even better the $50,625 minus $2500 isn't too bad. And if it is something you love to do the time is inconsequential.
