Almost every firm we talk to thinks they answer most of their calls. Then they pull the phone logs and get quiet. The calls they're missing aren't spread evenly. They pile up at lunch, after five, on Saturday, and during the hour when the one person on the front desk is also checking in a client.
Missed call rate is one of the easiest intake numbers to measure and one of the most useful. Here's how to get it right.
What missed call rate means
Missed call rate is the share of inbound calls that weren't answered live by a person or agent who could help the caller.
Missed call rate = inbound calls not answered live ÷ total inbound calls
The important word is "live." These all count as missed:
- Calls that rang out.
- Calls that went to voicemail, whether or not the caller left a message.
- Calls where the caller hung up while on hold.
- Calls answered by a message-taking service that couldn't run intake or book anything. Count these separately if you use one, because they're better than voicemail but still not a real answer.
Count new callers separately
Your phone system counts every call, including existing clients, opposing counsel, vendors and spam. That's fine for a staffing view. But for intake, you care most about calls from new people. If your phone system can't tell them apart, use the overall rate and spot-check a sample of missed numbers against your client list.
How to calculate it, with an example
These numbers are made up to show the math. Say your phone system shows 400 inbound calls last month:
- 300 answered live
- 70 went to voicemail
- 30 rang out or hung up
Missed call rate is 100 ÷ 400, or 25%.
Now split it by time:
| Time window | Calls | Missed | Missed rate | |---|---|---|---| | Weekdays 9 to 5 | 280 | 40 | 14% | | Weekdays after 5 | 80 | 40 | 50% | | Weekends | 40 | 20 | 50% |
This is the typical shape. Daytime looks decent. Evenings and weekends are where the leaks are. And those after-hours callers are often the most motivated people you'll hear from all week.
Then add the callback view
For every missed call from a new number, check two things:
- Did anyone call or text them back?
- How long did that take?
If 40 of your missed calls were from new people and only 22 got a callback, that's 18 leads who reached out and heard nothing. That's the number to put in front of the partners.
Where to get the data
- VoIP and cloud phone systems almost always have a call log or report with time, number, duration and outcome (answered, voicemail, missed). Look for "call history," "call detail records" or "analytics" in the admin panel.
- Older landlines may need a report from your carrier. Ask for call detail records for inbound calls.
- Answering services usually send a monthly report of calls handled.
- Your CRM can show whether a missed caller became a lead and got a follow-up.
If you can only get one thing, get a raw export of last month's inbound calls with time and outcome. You can build everything above in a spreadsheet.
What it costs you
It's tempting to treat missed calls as an annoyance. They're closer to a bill. You paid for most of those calls through ads, a directory listing or years of building a reputation. When the call isn't answered, some of those callers just call the next firm. We work through that math in what a missed call costs a law firm.
How to fix it
Cover the gaps you found, not the ones you assumed
Your time-of-day table tells you where to put coverage. If lunch is the problem, stagger breaks. If evenings are the problem, you need someone or something answering after five.
Stop sending new callers to voicemail first
A phone tree that makes a new caller press three buttons and then lands in a mailbox loses people. Route new-client calls to whoever's most likely to answer, and have a backup that rings if they don't.
Separate intake from the front desk where you can
The person checking in a client, handling the mail and answering the phone will miss calls. That's not a performance issue. It's a design issue. Even moving new-client calls to a dedicated line with its own coverage helps.
Add after-hours coverage that can run intake
A service that takes a name and number reduces voicemails but leaves the caller waiting. Coverage that can ask your intake questions and book a consult on the call closes the loop. Options are compared in AI receptionist vs. answering service.
Call back fast when you do miss one
Set a rule: every missed call from a new number gets a text within minutes and a call within the hour during business hours. Something like:
"Hi, this is the office of [firm]. Sorry we missed your call. We'd like to help. Reply here or call us back at this number and we'll get you taken care of."
Keep it general. You don't know yet who's calling or why, and you don't want a sensitive message landing on a shared phone.
What to do this week
- Export last month's inbound call log from your phone system.
- Calculate the overall missed call rate.
- Split it into weekday daytime, weekday evening and weekend.
- Pick 20 missed calls from unknown numbers and check whether each got a callback, and how fast.
- Choose one gap to fix this month, starting with the window that has the most missed calls.
Where IntakeGenius fits
The AI voice agent answers every call, 24/7, so the evening and weekend rows in that table stop being the problem. It runs your intake questions and books the consult while the caller's still on the line. IntakeCRM logs the lead and has SMS built in for the follow-up text. If you'd rather have a person on the phones, ask about our trained intake specialist.
