How the math works
Lost revenue = missed calls per week × average job value × your close rate on inbound calls. Someone who called you was ready to buy — inbound calls close at far higher rates than cold leads, so every one that hits voicemail carries real expected value.
The recovery estimate assumes an instant automated text back saves a conservative 50% of missed callers. In practice this varies by industry and urgency — emergency services (HVAC, plumbing) tend to recover more because the caller needs help now; considered purchases recover slightly less.

Frequently asked questions
How much does a missed call cost a small business?
It depends on your average job value and close rate. If you close 30% of inbound calls and an average job is worth $600, every missed call costs about $180 in expected revenue. Miss five a week and that is roughly $3,900 a month.
How many calls does the average small business miss?
Industry studies consistently find small businesses miss 20-30% of inbound calls — during jobs, after hours, on weekends, or while serving other customers. Most callers who reach voicemail do not leave a message; they call the next business on the list.
What does missed call text back do?
When a call goes unanswered, the system instantly sends the caller a text like 'Sorry we missed you — how can we help?'. That keeps the conversation alive before they dial a competitor. The calculator assumes a conservative 50% of missed callers are saved this way.
