I recently heard in a lecture that only churchgoing members in the US only tithe 2%, and of that percentage, 98% is used to cover the overhead of the church and staff, leaving 2% for what may be considered missions or evangelism.
Based on this latest report, I’m assuming that the downturn in the economy is going to mean that mission is less funded than before.

Yeah, giving by churchgoers is rather low. I’m not sure if the statistic is U.S. churchgoers giving around 2% of income, or only 2% of churchgoers actually donate 10% or more of their income. Either way, it is low. The 98% of going to staff and overhead, i.e. building and utilities, seems a little high. I think 50-65% feels more right. Now, 2% going to evangelism and/or missions sounds in the ball park. I’d venture a guess, just a guess, that the 33-48% remaining in my estimates would go to program expenses, e.g. curriculum, materials, etc.
