Where do the mormons get their money?

13 Million Members. About half of those are active. and about half of those are in the U.S. So lets say 3 million U.S. Tithing Payers. Then lets take the average income of those 3 million which would be 50k .. Then take ten percent of that which is $5000. Then multiply that by the 3 million. $15,000,000,000. If anyone can't count zero's that is 15 billion dollars. So lets be absolutly fair and take away 1/3 of that and say only 10 Billion annually taken in by tithing dollars yearly. Oh but don't worry they gave 300 million to charities over the last 15 years. Which is less than 1 percent of what they take in. They maintenance on facilities and building of new facilities does cost a lot of money. But a lot of the maintenance are done by volunteers and the actual money spend probably comes to about 5 billion. So at this day I would ume the LDS church makes a pure profit of 5 billion yearly. And I am low balling it.
