How this calculator works
The calculation is straightforward: missed calls × close rate × average job value = monthly revenue at risk.
If you miss 20 calls a month, close 40% of answered calls, and your average job is worth $800, you're leaving $6,400 on the table every month, $76,800 a year.
This is a conservative estimate. It doesn't account for repeat customers, referrals from satisfied clients, or the compounding effect of reputation damage from callers who couldn't get through.
The worked example in our article on the cost of a missed call approaches the same question from total weekly enquiries rather than missed calls alone. Either route gets you to a usable figure, use whichever set of numbers you actually track.
What to do with this number
Compare it to the cost of fixing the problem. Clearline is quoted per client rather than sold off a price list, so the honest answer is that it depends on what you need built. What is worth knowing is the order of magnitude: if the figure above is a meaningful number for your business, the maths on automation is straightforward.
