Here's a graph from a missionary's website. You may be surprised to know that more than half of the funds go toward the missionary's salary. Being able to live in a foreign country is difficult and many missionaries live off of the support they get from people back home. For this particular missionary, only 6% of the monthly support fund goes straight to ministry. As you may have guessed, it takes a very long time to establish a strong ministry in a foreign country, especially because missionaries must first settle themselves in their new home and get to know the people. This missionary is going to the Middle East permanently as a professor at one of the colleges in the area. He plans to build strong relationships with the students before doing any direct preaching. (Here's a breakdown of the monthly support for those who can't see the graph very well: salary 52%, fees and administration 20%, ministry 6%, travel 1%, insurance 21%)
