Minecraft PC sales are almost exclusively Mojang's money (except for merchant fees) except when it comes to the giftcards that can be purchased in stores like Target. Minecraft Xbox is a licensed product so it's fairly safe to assume that Mojang are sharing a non-negligible portion of the revenue with Microsoft. Pocket Edition is sold through mobile stores and developed by Mojang.

The Mojang and Notch AB financial records are public -- as it is the way Sweden works -- by the way, if for whatever reason you want to look into the money that they're making.

A cut through the iOS store, a cut through the Google Play store, a cut through Xbox Live Arcade Marketplace.

The IGN article says Minecraft sold 12 million on PC, so it's paying cuts on the other 21 million.
