Missed Call Cost Calculator
What the calls you miss are actually worth, computed with the formula on screen and every default cited to published research rather than vendor folklore. Compares doing nothing, a part-time hire at their loaded cost, and a 24/7 service — and it will tell you when none of them is worth buying.

The alternatives to compare
Enquiries walking away each year
$25,841
181 callers a year who did not leave a message and did not come back — before any option below is bought.
| Option | Covers | Costs / year | Recovers / year | Net |
|---|---|---|---|---|
| Voicemail (do nothing) | 0h · 0% | $0 | $0 | $0 |
| Part-time person (20 h/week) | 20h · 12% | $23,400 | $3,076 | -$20,324 |
| Answering service (24/7)best net | 168h · 100% | $1,188 | $24,549 | $23,361 |
“Covers” is measured against the 168 hours in a week a phone can ring, not a 40-hour rota.
- 20 hours a week is 11.9% of the 168 hours in a week. For the other 88.1% the alternative is not a person — it is voicemail, and most callers do not leave one.
- The service column assumes 95% of missed calls get answered, not that 95% of them become jobs. Answering a call is the only thing any service can promise; what happens next is your business, not the software’s.
If the after-hours column is the one that pays, that is the service we are building — in early access, with the intake script published.
Missed Call Cost Calculator: computed in your browser; nothing is transmitted.
Method: Lost revenue = missed calls × abandon rate × close rate × job value; each option recovers its coverage share, net of its own annual cost. Defaults cite the verified-stats pack when present. Pinned in tests/missedCalls.test.ts, including the do-not-buy verdict.
🎓 Understand this tool
What it is
An estimate of what unanswered calls cost a business over a year, and a comparison of the three honest responses: doing nothing, paying a person for part of the week, or paying a service for all of it. Its distinguishing feature is that it can conclude none of them is worth it.
How it works
Missed calls are multiplied by the share of callers who give up rather than leaving a message, then by your close rate and your average job value. Each coverage option recovers the share of those enquiries that falls inside its hours — measured against the 168 hours a week a phone can ring — and its recovery is netted against its own annual cost, with the part-timer priced at their loaded employer cost rather than their bare wage.
Getting the most from it
- Count the calls you actually miss in a typical week — after hours, mid-job, on the other line.
- Set your average job value and close rate; the defaults are cited to published research where a verified figure exists, and labelled as your own estimate where it does not.
- Adjust the abandon rate if your customers behave differently from the surveyed ones.
- Compare the three columns on their net figures, not their recovery figures — coverage that costs more than it recovers is a loss with better manners.
Reading your result
The headline is the revenue represented by callers who gave up. The best-net badge marks the option that pays for itself by the widest margin — and when no option does, the verdict says so first, because at low volumes the right amount to spend on this problem is nothing.
What it can't tell you
It estimates enquiry value, not guaranteed revenue: answering a call is the only thing any service can promise, and what happens next is your close rate, not the software’s. The clinical research behind reminder statistics comes from healthcare settings and is a direction, not a promise for your trade.
Frequently asked questions
From published research with a named publisher, date and sample size — shown beside each field — never from the recycled vendor statistics this category runs on. The famous "80% of callers won’t leave a voicemail" figure traces to an unattributed 2014 magazine piece with no study behind it, so it does not appear here; a 2025 survey of 1,000 consumers is the kind of source that does.
