Recent data in my denomination (UMC) showed a typical range of between $300,000 and $500,000 in denominational subsidy per new church plant, depending on the region and how deep its pockets. And roughly 2/3 of the projects survived the first five years. However, this measures only the denominational monetary contribution - typically in the first three years. The real cost of a church plant also includes donations by members and participants, sponsoring churches and other friends of the church. And it sometimes includes a donated building!
