I guess it depends on the app
Clearly it depends on the app.
We are currently working on a mass market app that should have very broad appeal. Development, marketing and support costs will be right around $150k in the first year, with ongoing support costs coming in about the same each year. If we don't sell 100,000 copies a year, the app will be a financial failure. We will price this one at $3.99 based on the competition, and expectations are high.
Let's break this down in the simplest of terms
Gross sales of 100,000 = $399,000
Apple takes 30%, so net sales = $279,000
Development, marketing and support first year is $150,000 so gross profit is $129,300
Taxes are 28% Federal and 10% State so net profit is $83,786
If we were to have sold that same 100,000 copies at $2.99 the net profit would have been only $38,426. At $1.99 it would have been a net loss of ($10k).
Since development, marketing and support costs for an app like this typically run $150k in the first year, we cannot even build a second app until the end of the second year assuming sales stay constant at 100,000 and costs do not go up unexpectedly.
What do we pay our investors with? If it comes out of that $83k net the first year, we do not get a chance to write that second app and grow, so when this app stops selling we close the doors...
The investors say sell that app for $4.99, so that first year net is $129k, but will the market bear that cost? Will we have to spend more than $40k in additional marketing to get those sales (resulting in a wash...).
It's the unusually successful app that sells 100,000 copies...
