How it works
How we calculate the cost of a missed call
The calculator multiplies five numbers in order. Here's a plumber who misses 30 calls a month, run with the calculator's starting figures.

How much does a missed call cost a business?
It depends on your trade, booking rate, close rate and average job. A plumber who misses 30 calls a month loses about $252 per missed call, or $90,588 a year, using the calculator's starting figures. Enter your own numbers above to see yours.
Where do the default numbers come from?
Each one links to a published source. Quo covers callbacks, ServiceTitan and Invoca cover booking and conversion rates, ServiceTitan and Siro cover close rates, and Angi covers job values. We leave out any figure we can't trace to a study.
Why does the sales rate start at 62% for some trades and 25% for others?
ServiceTitan found typical plumbing, HVAC and electrical contractors close 62% of estimates on the first visit, so those trades start there. Every other industry starts at 25%, a conservative figure set below the published close rates we found. Slide it to your own close rate.
How do I find out how many calls I miss?
Open your phone's call log or your phone provider's dashboard and count last month's unanswered calls. That number goes in step 2.
Is the result a guarantee?
No. It estimates the sales you lose, using published averages. Your own call log, booking rate and close rate make it more accurate.
