How to Use This Calculator
  1. Enter total children in ministry and the breakdown by age: infants (under 2), toddlers/preschool (2–4).
  2. Input current volunteer count.
  3. Review Volunteers needed (minimum for safe ratios) and Volunteer gap to know how many more to recruit.
  4. Check Safety ratio score (1–5) — a score of 1 means critical shortage requiring immediate action.
  5. Use Rooms needed and Total volunteer pool for facility and staffing planning across multiple services.
