The Real Cost of a Missed Call for a personal injury firm

Last reviewed 31 July 2026  ·  Benchmark figures and study numbers checked against the linked sources on the date shown.

What does one missed call actually cost a law firm?

At minimum, what you paid to make the phone ring. In LocaliQ’s 2026 search advertising benchmarks, the Attorneys & Legal Services category showed an average cost per lead of $131.63, from an average cost per click of $9.87 and a conversion rate of 5.55%. That is the floor, and it is spent whether or not anyone picks up.

The case behind the call is worth more than that, obviously. We are not going to tell you how much more, because we could not find a personal-injury case-value figure we were willing to stand behind, and inventing one would make every number below it useless.

The floor is enough to make the point. It is a real, published, checkable number, and it is already spent by the time the phone rings.

What does a legal lead cost to acquire?

The published 2026 benchmark for the Attorneys & Legal Services category is $131.63 per lead. That comes from an average cost per click of $9.87, an average click-through rate of 5.87%, and an average conversion rate of 5.55% once the click lands. Personal injury sits at the expensive end of that category rather than the average.

Those are category averages across all legal services.¹ If your firm buys personal injury keywords, your real cost per lead is above that line, not below it. Use your own figure where you have one; use this as the conservative substitute where you do not.

How many of those calls actually go unanswered?

In the study behind Clio’s 2024 Legal Trends Report, researchers approached 500 US law firms as prospective clients. Only 33% replied to the email, only 40% answered the phone, and 48% did neither. Five years earlier the same test found 40% replying to email and 56% answering the phone. Both numbers moved the wrong way.

The 2019 round emailed 1,000 firms and called 500 of them.⁴ The 2024 round tightened the sample and the results got worse, across a period when firms were spending more on generating those inquiries, not less.²³

How do you run this math for your own firm?

Four numbers and two lines of arithmetic. Take your monthly marketing spend, divide by the number of inquiries it produced to get your real cost per lead, count how many of those inquiries never reached a human within one business day, and multiply. That figure is money you spent on conversations that did not happen.

• A — monthly marketing spend. Everything that generates inbound: search, referral fees, directories, television.
• B — inquiries received. Calls plus web forms plus chats, counted honestly, including the ones nobody logged.
• Your cost per lead = A ÷ B. Use $131.63 as a stand-in only if you cannot produce A and B.
• C — inquiries with no human contact within one business day. Count them for four weeks, do not estimate.
• Wasted spend = C × (A ÷ B).

An illustration, with a made-up inquiry count and the published benchmark standing in for cost per lead: a firm receiving 120 inquiries a month, of which 30 never reach a human, is spending 30 × $131.63 = $3,948.90 a month on inquiries that produced no conversation at all. Substitute your own numbers; the point is the shape, not our arithmetic.

Does calling back the next day recover the lead?

The evidence says much less often than firms assume, though the best-known study is old and was not run on law firms. The 2011 Harvard Business Review audit of 2,241 US companies found that firms contacting a lead within an hour were nearly seven times as likely to qualify it as those waiting one hour longer, and more than sixty times as likely as those waiting a day or more.

The same audit found the average response time, among companies that responded at all within thirty days, was 42 hours.⁵⁶

Two honest caveats. It is from 2011, and it covers companies generally rather than law firms. We cite it because it is the study everyone else is paraphrasing without saying so, and because the direction it points is consistent with what Clio found in legal specifically.

What is the cheapest thing to fix first?

Coverage, not speed. A firm answering every inquiry within ten minutes during office hours and none of them after six o’clock has a coverage problem, and coverage is far cheaper to fix than speed. Measure the two separately for four weeks before spending anything, because the fix for each is different.

• Log every inquiry with its timestamp for four weeks, including the ones that never got a reply.
• Split them into office-hours and out-of-hours before looking at response times.
• Measure time to first human contact, not time to first automated acknowledgement.
• Run the secret-shopper test on yourself from an outside number, in the evening, twice.

Four weeks of that produces a number no vendor can argue with, including us. If the out-of-hours column turns out to be empty, you already know what the first fix is, and it is not another keyword.
