In Baptist circles, seminary is just like college for secular students. The student pays for his or her own tuition. (O.K. for Pastors in conservative Baptist Churches I may as well just say "his own tuition".)
As an example... In my neck of the woods, most Baptist pastors-to-be attend Maranatha Bible College. their tuition and costs page is found here, explaining what a student needs to know.
And just like secular schools, there are scholarship and financial aid options available.
