Layer 1: Invitation Conversion Rate (ICR)
This is the percentage of the amount of people that get invited to church that actually end up coming. Between 60% & 90% of people invited to come to church by a friend will come.
Layer 2: Guest Integration Rate (GIR)
This is the percentage of visitors becoming regular attenders. This number is around 33%. Not all visitors are created equal. There’s 3 categories of people: churched, unchurched, and de-churched people. Where your church family is inviting people from will have huge implications on whether or not they stick long-term.
People who are already connected at another church aren’t likely to stay around at your church.
Go after those who are unchurched and dechurched to increase your guest integration rate.
Layer 3: Annual Membership Invitation Rate (AMIR)
How many people your congregants actually invite per year per person. You’re doing good if your congregants only invite one person to join them per year. (This means your rate would be 1. If each congregant invited 2 people, your rate would be 2).
Scenario: If a congregant invites 1 person each year for 4 years, 3 of them will say yes. Out of those 3 people, 1 of them will become a regular attender. This means that every 4 years, your congregation size should double (or increase by a quarter each year).
Goal #1: Increase the number of people your congregants are inviting. Get it up to 4. Every 3 months, do a campaign or emphasis on getting each congregant to invite 1 person.
Now, if congregants invite 4 people per year, 3 will come. If 3 people come, 1 will stick.
Why don’t people invite others to church? We don’t ask our people to invite others and we don’t give them the tools and resources to invite people.
AMIR x ICR x GIR x [Church Size] = # of new guests per year
