Ok, I downloaded the matrix but haven't input the info. yet. So I'm hoping you can help me out.
Here's the cake: 2 layer 12x18, 2 layer 8", a 6" (cake) shopping bag, gumpaste shoe. Buttercream with fondant detailing.
it sounds like you know this, but you need to sit down and work out *your* costs.
a cheap standard bc price on here, for a basic round/ square is $2 a slice (wedding sized serving).
fondant accents = price increase.
carving = price increase (takes time, harder, also to cover cost of waste cake - an average, cheap, price for a carved cake is about $5 a slice).
gumpaste shoe = individually priced - quite high, depends on the size of the shoe.
dont be afraid to price high for a cake that will be more work and time than a basic round, working for cheap just to get the order means you are not making any money.
12 X 18 plus the 8" serves 132 times my bc w fondant motifs price = $462
bag, cvered in fondant = $56
Equipment = $20
total before delivery = $578
a) that's a LOT of cake
b) that's custom work
c) and as always, please remember that your state/county/city may require you to be inspected/licensed/insurered or you may not even be permitted to sell a cake at all. That's a lot of work to do to discover that you might not be able to be paid at all for it.
