No published study has calculated cost-per-retained-member across Adventist youth ministry channels. This is remarkable for an organisation spending billions on youth infrastructure.
Here's a back-of-envelope calculation:
Full K-12 Adventist education costs approximately AU$120,000 total (AU$10,000/year × 12 years). It yields 98% retention versus a 51% baseline.
That means for every 100 students, you retain 47 additional members compared to no Adventist education. Total cost for 100 students: AU$12 million. Cost per additional retained member: approximately AU$255,000.
Is that a lot? Consider this: a retained member who tithes for 40 working years at an average Australian income contributes AU$200,000-$500,000+ in lifetime tithe. The investment more than pays for itself.
Compare other channels:
- Pathfinders: ~$200-500/year per participant, 85% stated intention to stay (but no long-term data) - Summer camps: Limited cost and retention data - Conference youth programs: ~US$1,500 per youth per year benchmarked
Education is the most expensive channel but has by far the strongest evidence. Pathfinders are cheap but unproven at scale. Camps are popular but unmeasured.
The critical analytical gap: no denomination has published a rigorous cost-per-retained-member comparison across ministry channels. We're investing billions without knowing what works best per dollar.
Stewardship demands evidence. The evidence demands better data.
