Arment walked me through the numbers. He has 25,000 subscribers who pay $1.99 a month. Apple takes a 30 percent cut, leaving Arment about $35,000 a month.

This cost of putting out the magazine is a bit over $20,000 per month. It comes out every two weeks, and each issue costs about $10,000. Roughly $4,000 goes to writers. The rest goes mostly to copy editors, illustrators, photographers and editors.

Wow. Amazing numbers, considering that Marco Arment launched it as a mere experiment. The Magazine is packed with readable, high-quality articles and absolutely deserves that kind of success.
