70/80 Rule
70% = Watch (begin planning); 80% = Act Now (add service or expand).
The 70/80 Rule is a capacity planning framework used by Kingdom Metrics to give church leaders clear, actionable thresholds. At 70% of behavioral capacity, a service enters the "Watch" zone — this is the trigger to begin researching and planning for growth. At 80%, the service enters the "Act Now" zone — concrete steps should already be in motion.
This framework applies primarily to flagship services, where capacity constraints have the greatest impact on overall church growth. Bookend services and smaller venues may tolerate higher utilization without the same guest-experience impact.
Why it matters for your church: The 70/80 Rule removes the guesswork from capacity decisions. Instead of debating whether the room "feels" full or waiting until attendance visibly declines, your team has two clear numbers that trigger two clear responses: plan (at 70%) and execute (at 80%).
