How to calculate what missed calls cost your business
You do not need a study to know what missed calls cost you. You need four numbers from your own business and about ten minutes.
Step 1. Count your missed calls
Open your phone system or carrier log and count calls that went unanswered or to voicemail over the last 30 days. Include calls outside opening hours, since those are often the biggest group.
Step 2. Estimate how many were real opportunities
Not every missed call is a customer. Spam and wrong numbers do not count. Listen to a sample of voicemails, or check call-back notes, and estimate the share that wanted to book, buy or ask for a quote.
Step 3. Apply your own close rate
Look at your calls you did answer and how many became appointments or sales. Use that rate for the missed ones. Be conservative, because a caller who reaches voicemail often calls the next business.
Step 4. Multiply by your average job or sale value
The formula is simple.
Missed calls x share that were real opportunities x close rate x average value = monthly revenue at risk.
Run it with a low and a high estimate so you see a range instead of one number.
What to do with the result
If the range is meaningful for your business, the next step is to answer more of those calls. That can mean extra staff, an answering service or an AI voice agent. An agent answers 24/7, books appointments in your calendar, captures lead details and passes urgent calls to a person.
Track it after the change
Repeat the count after a month. Compare unanswered calls, booked appointments and call-backs. Your own before and after is the only number that matters.
What it costs to try
InfiVoice bills in credits, and one credit equals 60 seconds of call time. The Free plan includes 100 credits. Pro costs $79 per month with 250 credits.
Frequently asked questions
Where do I find my missed call count?
In your phone system, carrier portal or call log. Export the last 30 days.
Should I include after-hours calls?
Yes. They are often calls nobody could have answered, and they show the gap an agent can close.
Can an agent handle every call?
It handles the calls you set it up for, and you choose when a call goes to a person.
