Enter your current attendance, growth goal, and timeframe. See the required monthly growth rate, projected milestones every 3 months, and a visual growth curve.
Church attendance growth is both a spiritual and a mathematical reality. Prayer, preaching, and community drive it — but so do visitor follow-up rates, attrition patterns, and size-threshold dynamics that every growing church eventually faces. Understanding your church's growth math helps you see where to focus energy: Are you bringing enough visitors in? Are you retaining them? Are you losing people out the back door faster than you realize?
This free attendance growth calculator lets you input your current attendance, monthly visitor rate, retention percentage, and attrition rate — and then projects your 12-month attendance trajectory. It's useful for planning staff hires, service additions, facility decisions, and outreach budget discussions. No account required.

This calculator uses a compound growth model based on three variables: how many new visitors you attract each month, how many of those visitors become regular attenders, and how many current attenders leave. The net effect compounds over time — small changes in retention rate have outsized long-term impact.
The projection assumes your visitor rate and retention rate remain constant. In practice, growth is non-linear — churches often plateau at certain size thresholds (65, 125, 350, 1,000) that require structural changes to break through. Use this projection as a directional guide, not a guarantee.
The Church Resource Planner generates a technology roadmap matched to your size and growth trajectory. Start planning before you hit the next threshold.
