Doodle Jump celebrates two years, 10m downloads, heading to Kinect

Well, if that's all you ever sell, then yes, you won't receive any money. If you sell 150 copies in March though, that should roll over to April, and if you sell another 150 in April then should get paid for the 300 total after April ends.

Your money should roll over until it reaches a $150 net total, or the end of the financial year. Not sure what happens at the end of the year, if they pay you any outstanding money or just keep it.

If you fail to reach $150 net and let your paid developer contract expire Apple keeps all of the money

It actually gets even a little more complicated. You actually have to reach the equivalent of $150 net in each *market* that you are selling your app in to get paid, not total. So if I am selling it in the US and in Europe, I have to reach $150 net in the EU before I am paid for those apps, and $150 net in the US before I am paid for those apps. So you can end up with quite a bit of money being owed to you.

Getting back to the original question... assuming Doodle Jump has always been $0.99 then if they have sold 10m copies, their net should be $7m.

It's pretty simple really. You decide how much you want to charge for your app (from about a dozen price points), Apple takes a 30% cut and pays out the rest to you once a month.

Well, as long as you net at least $150 in a month anyway. So if you have a $0.99 app, you need to sell 215 copies or more before you can get paid. It takes almost a month to get paid as well, so you get the money for March's sales by the end of April.

That's it.

Sorry, that should be "a *few* dozen price points"
