Missed-call cost calculator
Five numbers you already have, or can count in a week, and the calculator shows what unanswered calls are costing you. The defaults are placeholders; your own figures are the point.
Defaults are illustrative, not industry statistics. The missed share is the one worth measuring: count calls against answered calls for a week.

Missed calls × callers who don't call back × your conversion rate × customer value. Change any input and the result updates. Nothing is sent anywhere.
How to get real numbers into it
Calls per weekcomes from your carrier portal or phone system; if you can't get it, count for one week. The missed shareis total calls minus answered calls, and it's the number most businesses have never measured. Include after-hours calls if the system logs them.
The never-call-back shareis the honest unknown. Urgent, first-time callers mostly don't; existing customers mostly do. If you're an appointment business found through Google, start high and adjust. Conversion rate is the share of answered new-customer calls that book; customer value is a first job or first-year value, whichever you plan around.
Whatever the result, compare it with the cost of answering. Forwarding unanswered calls to an AI receptionist is a flat monthly fee, the setup is one carrier code (see how to forward calls), and it reverses in a minute if it isn't worth it.
Missed-call calculator FAQ
How do I find out how many calls I'm missing?+
Your carrier or phone-system portal shows total inbound calls; compare that with calls you actually answered for one week. If you can't get the total, count voicemails plus the missed-call log on the phone for a week and treat it as a floor. Businesses are usually surprised by the number, which is why the calculator asks for it rather than assuming one.
Why does the calculator ask how many callers never call back?+
Because a missed call is only a lost customer if the caller doesn't try again. Someone with a toothache or a burst pipe calls the next listing rather than leaving a voicemail; a loyal customer calls back later. The share depends on your business, so it's an input, not an assumption.
Are the default numbers real statistics?+
No. They're placeholders so the calculator shows a result before you type. Every input should be replaced with your own figures; the missed-call share and the never-call-back share are the two that move the result most.
What's the cheapest way to stop missing calls?+
Conditional call forwarding to something that answers when you don't: a colleague, a human answering service, or an AI receptionist. Forwarding is one carrier code and reverses in a minute. An AI receptionist answers every call for a flat monthly fee, which is usually far below the revenue the calculator shows.
Does the calculator include after-hours calls?+
Only if you include them in the calls-per-week figure. If your phone system logs calls outside your hours, add them; those are the ones most likely to ring out and least likely to be called back.
