How the calculator works

The math is straightforward: after-hours calls multiplied by the 85% voicemail abandonment rate, your close rate, and your average job value gives your monthly revenue at risk. Multiply by 12 for the annual figure. The annual number is the one that matters — it represents revenue you lose from leads you have already paid to generate, not from additional marketing.

Frequently asked questions

How does the missed call calculator work?

The calculator uses three inputs — your monthly inbound call volume, average job or transaction value, and the percentage of calls that come in after hours — to estimate the revenue you lose each month and year. It applies a documented 85% voicemail abandonment rate and your close rate to model the jobs lost to unanswered calls.

What is a typical after-hours call rate for my industry?

After-hours call rates range from about 48% for pest control to 71% for locksmiths, with most home-service trades between 52% and 62% and healthcare and legal often above 65%. The calculator pre-loads benchmarks by industry, and you can adjust the rate to match your own data.

Why does the calculator assume 85% of voicemail callers never call back?

Call-tracking research across service businesses consistently shows that when a high-intent caller reaches voicemail on their first attempt, about 85% do not leave a message and do not call back — they call the next result on Google. This is documented behavior, not a pessimistic assumption.
