Missed-Call Revenue & AI Receptionist ROI Calculator
Multiply your monthly calls by the share you miss, the share that are genuine prospects, your close rate and your average job value to estimate the revenue at risk. This free calculator does that, then shows conservative, likely and optimistic recovery scenarios and how quickly an AI receptionist would pay for itself — with every assumption editable.
Never miss a job-winning call again
Our AI receptionist answers every call 24/7, texts back missed callers in seconds, and books or qualifies the job — so the revenue in this calculator stops leaking.

What this tool calculates
It estimates how many calls you miss each month, how many were genuine leads, the jobs and revenue that likely slip away, and what you could recover. It then shows a break-even — how many recovered jobs cover an AI receptionist's setup cost — and an estimated payback period. Every number is an estimate you control, not a hidden industry stat.
The formula (and your assumptions)
Missed calls/month = calls × % missed. Qualified leads = missed calls × % genuine prospects. Jobs lost = qualified leads × close rate. Revenue at risk = jobs lost × average job value. Recovered revenue = revenue at risk × the share of calls you think an AI receptionist could recover. We show that at three visible rates — conservative, likely and optimistic — rather than baking in an exaggerated number.
- Every input is yours — we don't hide inflated defaults inside the math.
- Conservative / likely / optimistic scenarios flex the recovery rate you set.
- Break-even = setup cost ÷ average job value (jobs needed to pay it back).
- Results are estimates to guide a decision, not guaranteed outcomes.
Worked example
A plumbing shop takes ~50 calls a week and misses 20% of them. About 70% are genuine prospects and they close 40% at an average job value of $1,200. That's roughly 43 missed calls a month, 30 qualified leads and 12 lost jobs — about $14,500 in revenue at risk every month. Recovering even a conservative share pays back a $1,500 AI receptionist setup in a matter of weeks.
How to use it
- 1Enter your call volume and the percentage you miss.
- 2Set what share are genuine prospects, your close rate and average job value.
- 3Set how much of those calls you think could be recovered.
- 4Optionally add an AI receptionist setup cost to see payback.
- 5Read your revenue at risk and conservative-to-optimistic recovery.
Key takeaways
- Missed calls are usually a bigger leak than contractors think.
- The math is only as strong as your inputs — keep them honest.
- Even conservative recovery often pays back call-answering fast.
Assumptions & limitations
- These are planning estimates based on the numbers you enter — not a promise of recovered revenue.
- Not every missed call is a lost job; that's why you set a 'genuine prospect' and 'recoverable' rate.
- Recovery rates are shown as editable scenarios so you can be as cautious as you like.
Questions contractors ask
How much revenue do missed calls actually cost?
It depends entirely on your call volume, close rate and job value — which is why this tool asks for your numbers instead of quoting a scary industry figure. Enter your own and see a range you can trust.
What is a realistic call recovery rate for an AI receptionist?
Rather than assume one, the tool lets you set a recoverable rate and shows conservative, likely and optimistic scenarios around it, so the estimate reflects your caution, not ours.
Is an AI receptionist worth it for a contractor?
If you regularly miss calls while on a job, recovering even a few per month can cover the cost. The break-even and payback figures here help you decide with your own numbers.
