Frequently asked questions
How do you calculate the ROI of an answering service?
Multiply your weekly calls by 52, then by your missed-call rate (default 27%, from Invoca), to get the calls you miss in a year. Multiply by your close rate for the jobs lost, then by your average job value for the revenue lost. The return is that recovered revenue divided by the service’s annual price — a $49/mo plan costs $588 a year, so recovering far more than that is the ROI.
How much revenue do missed calls cost a service business?
It depends on your call volume, close rate, and average job value. According to Invoca, about 27% of calls to home-services businesses are not answered. This calculator multiplies your own numbers, 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.
What is a good ROI for an answering service?
Any return above 0% means the service recovers more than it costs. Because an answering service is a fixed monthly cost ($49–$249 for Ringbook) while a single recovered job can be worth hundreds, the break-even point is usually one or two booked jobs a year — so the ROI is typically many times the cost. The calculator shows the exact multiple from your numbers.

Every unanswered call is a job that may go to the next business the caller dials. According to Invoca, 27% of calls to home-services businesses are not answered (Invoca, read 2026-06-15). The cost is not a flat per-call number — it is the value of the work you would have booked, which is why this calculator multiplies your missed calls by your own close rate and average job value. For a more detailed look at the cost side, see the missed-call cost calculator.
How we calculate answering-service ROI
The math is deliberately simple so you can check it: calls per year = your weekly call volume × 52. Missed calls = calls per year × the missed-call rate (default 27%, from Invoca). Jobs lost = missed calls × your close rate. Revenue lost = jobs lost × your average job value. The ROI is the revenue an answering service recovers divided by its annual price — a $49/mo plan costs $588 a year.

Any return above 0% means the service recovers more than it costs. Because an answering service is a fixed monthly cost while a single recovered job can be worth hundreds, the break-even point is usually one or two booked jobs a year. A bilingual answering service that books the job and texts you the details is one way to recover those calls; see the best AI receptionist comparison for how tools differ.
