What do missed calls cost your business?
Last updated: July 23, 2026
You do not need an industry study to know what missed calls cost you; you need your own four numbers. Put them in below. The starting values are just an example (a trade business missing five calls a week at a $350 average ticket); replace them with yours.
- Lost jobs per week
- 1.2
- Revenue walking away per month
- $1,820
- Per year
- $21,840
At 50% gross margin that is about $10,920 a year in gross profit.
The formula, in the open
missed calls x real-customer share x win rate x average job value = lost revenue per week
Weekly lost revenue times 52 gives the yearly figure; gross margin turns revenue into gross profit. Two honest caveats. Some missed callers do call back, so your true loss is lower than the raw math; and repeat-customer value is not counted at all, which pushes it higher, especially for trades where a first job turns into years of service calls. The point of the calculator is not three decimal places. It is whether the number is bigger than the cost of fixing it.
Where the estimate comes from for each input
- Missed calls per week: your phone’s missed-call log and voicemail count. Most owners undercount; check a real week.
- Real-customer share: what fraction of your inbound calls are genuine prospects rather than spam, robocalls, or wrong numbers.
- Win rate if answered: of the genuine callers you actually talk to, how many book? Use your gut number, then stress-test the result with half of it.
- Average job value: your invoices. Use the median ticket if a few huge jobs skew your average.
If the number hurts, here are the fixes
We compared all nine real options, free to full-time hire, in how to stop missing business calls. The short version: tighten your phone setup first, then put something that answers on the other end of your call forwarding. Nevermiss is the AI receptionist version of that: it answers 24/7 in your business name, captures the job, and texts you the details, from $99 a month. A single saved job can pay for months of it, which is exactly the math the calculator above lets you check. Hear it answer live before you decide anything.
