The following is in Canadian dollars:

About $20 is "standard", but I have seen rereleases at $7 in bargain bins, and some artists charge $30, $35...

The cost of a massproduced CD, just the physical stuff, is probably less than a dollar, but a lot is spent for promotion, to persuade people to buy it. (And then a lot goes to pad the record company's bank account.) The "top" artist does't see much of that $20 at all... but if enough sell, then there's a living.

For indie CDs, like mine, the cost of one CD is astronomical, and the more money you have up front, the less it costs to make. One indie friend gets his made locally, $650 for 100 CDs, including art. ($6.50 each.) You could buy the supplies for 100 CDs (CDr, disc labels, jewel case labels) for about $350, making it $3.50 each. Or, if you have the money, you can get 1000 CDs for $1500. (At $1.50 each. If you have the money in the first place, and a way to sell that many!)

I am charging $5 per Artist CD to sell the CD on my site. And I will be charging more per compilation, on top of a production cost. Which will reduce the amount each artist gets from the compilation, but hopefully people will buy their individual CDs after hearing them on the compilation. Out of that $5 comes taxes, discounts, any promotion costs, etc. Fortunately the web space was donated. So I don't have to worry about that for at least a year. And I am going to have to charge shipping, which I didn't originally want to do. Oh, well.
