Missed Call Cost Calculator

Every unanswered call to a plumber, HVAC company or roofer is a customer who may already be dialing the next number on Google. This calculator puts a dollar figure on that. Enter your own call numbers and job value; it shows what missed calls cost you each month and how many saved jobs a missed-call fix needs to pay for itself.

How the math works

Missed calls per week × 4.33 gives missed calls per month. That number × the share that are new job inquiries × the share who never call back gives the inquiries you lose. Those inquiries × the share you normally book gives lost jobs, and lost jobs × your average first job value gives the monthly cost.

The break-even line divides the monthly cost of a fix by your average job value. If a $50 a month tool saves one $350 job every seven months, it has paid for itself.

Where to get your numbers

• Missed calls: your carrier app, VoIP dashboard or field service app call log usually lists unanswered calls and voicemails by week.
• New job inquiries: listen to a week of voicemails and count the ones asking for a quote or a visit.
• Booking rate and job value: your field service or invoicing software reports both; use the first job, not lifetime value, so the estimate stays on the low side.
• Callers who never call back: vendors that sell answering tools publish figures between 60% and 85%, but none of those surveys are independent. Try 50% and 80% to see the range.

What to do if the number is high

The cheapest fix is an automatic text to every missed caller, which many phone and field service apps include. Our guide to setting up missed-call text back covers the main options, and the version for roofing contractors shows how it works when the crew is on a roof all day. If you need someone or something to actually answer, compare an AI receptionist with a human answering service, or see our list of the best AI receptionists for small businesses.
