Frequently asked questions
How much do missed calls cost a service business?
It depends on your call volume and your average job value. According to Invoca, about 27% of calls to home-services businesses are not answered. This calculator multiplies your missed calls by your own average job value, so a roofer at a $1,200 average job loses far more per missed call than a detailer at $200 — there is no single fixed dollar figure per call.
How is the annual missed-call cost calculated?
Monthly missed calls = your monthly call volume × the missed-call rate (default 27%, from Invoca). Annual missed-call cost = monthly missed calls × 12 × your average job value. You can lower the booking rate if not every missed call would have become a paying job.
What percentage of calls do service businesses miss?
According to Invoca, about 27% of calls to home-services businesses are not answered. The calculator uses 27% as the default missed-call rate, but you can change it to match what you actually see — after-hours, lunch rushes, and being on a job all push the real number higher for solo operators.
How many jobs does an answering service need to recover to pay for itself?
Divide the answering service’s annual cost by your average job value. For a $49/mo service ($588/yr), a business with a $400 average job value only needs to recover about two booked jobs a year to break even — anything beyond that is profit. The calculator does this break-even math from your numbers.

The math is deliberately simple so you can check it: monthly missed calls = your monthly call volume × the missed-call rate (default 27%, from Invoca). Annual missed-call cost = monthly missed calls × 12 × your average job value. If not every missed call would have booked, lower the numbers and re-read the result — the on-screen total updates as you type.
What percentage of calls do service businesses miss?
According to Invoca, 27% of calls to home-services businesses are not answered (Invoca, read 2026-06-15). We use 27% as the default missed-call rate. It is an industry figure for home-services businesses, not a guarantee for your shop — adjust it to match what you actually see.

How an answering service recovers the cost
An answering service pays for itself once it recovers more revenue than it costs. Divide its annual price by your average job value to get the number of booked jobs it has to win back — the calculator above does this for a $49/mo service. A bilingual answering service that books the job and texts you the details is one way to recover those calls; an after-hours answering service targets the nights-and-weekends calls that are often worth the most.
