How we calculate, and where the numbers come from
The 6 steps of the math:
- Calls per week × % missed = missed calls per week.
- Missed calls × % who never call back = customers who never call back.
- Customers who never call back × conversion rate = new customers lost per week.
- New customers lost × average value × 4.33 weeks = loss per month.
- The conservative scenario divides the monthly loss by two, on purpose.
- Conservative monthly loss × 12 = conservative loss over a year.
