Law Firm KPIs: The Numbers That Explain Why Revenue Moves

Most injury firms track two numbers closely: how many cases came in and how much the firm collected. Both matter, and both arrive late. By the time a weak month shows up in fees, the problem that caused it happened a year or more earlier, somewhere between the first phone call and the signed agreement.

Key performance indicators, or KPIs, are the handful of numbers that let a firm see those problems while there is still time to fix them. The point is not to build a dashboard with forty charts. It is to pick the few numbers that explain why revenue moves, review them on a schedule, and act when one of them changes.

Think in stages, not departments

An injury case moves through a predictable sequence: someone contacts the firm, the firm reaches them, the case is evaluated, the client signs, the case is worked, and it resolves. Each stage can leak. Good KPIs are spread across the whole sequence, so that when revenue drops you can see which stage it dropped at instead of arguing about it.

Intake: the numbers that decide what you ever get to work

Speed to first contact. How long it takes, on average and at the slow end, from the moment an inquiry arrives to the moment a person at the firm actually speaks to the caller. Look at the slow end, not just the average. A good average can hide a lot of inquiries that waited hours, especially at night and on weekends.

Contact rate. Of the inquiries that came in, how many did the firm actually reach? An inquiry the firm never speaks to is not a bad lead. It is a lead nobody worked.

Qualification rate. Of the people reached, how many had a case the firm would take? This mostly reflects where the inquiries come from. A falling qualification rate usually points at a marketing source, not at the intake team.

Sign rate. Of the qualified callers, how many signed? This is where intake skill shows. Track it by intake staff member and by source, because a single firm-wide number hides the differences that tell you what to fix. The guide to legal intake software covers what tools can and cannot do for these numbers.

Marketing: measure the case, not the click

Cost per signed case, by source. Divide what a channel cost by the cases it produced. Cost per lead is useful for spotting a broken campaign quickly, but it says nothing about whether the leads become clients. Two sources with the same cost per lead can produce very different cost per case. The guide to personal injury marketing explains how to plan spend around this number.

Source mix. What share of signed cases came from each channel: referrals, past clients, search, paid campaigns and so on. A firm that depends on a single source is exposed if that source changes, even when every other number looks healthy.

Case mix. The types of case being signed, and their likely value. A month with more signed cases can still be a weaker month if they are mostly small property damage claims.

Case work: the numbers between signing and settlement

Time to key milestones. How long it takes from signing to the end of treatment, to the demand letter going out, and to resolution. Long gaps between treatment ending and the demand being sent are a common sign of a caseload that has outgrown the team.

Caseload per case manager. The number of open files each person carries. When this climbs, client communication is usually the first thing to suffer, and slow communication tends to show up later as complaints, bad reviews and clients leaving.

Client drop-off. How many signed clients leave the firm, stop responding or switch to another lawyer before resolution, and at what stage. Each one is a case the firm paid to acquire and will not be paid for.

Outcomes: what the firm actually earns

Average fee per resolved case, by case type and source. This is what turns cost per signed case into something meaningful. A source with a high acquisition cost can still be the best one if its cases resolve for much more.

Time to fee. How long, on average, it takes for a signed case to produce money. This drives cash flow and tells you how far ahead the firm has to plan its spending.

Referral and repeat rate. How many new cases come from past clients and their families. It is one of the clearest signs that clients had a good experience, and those cases usually cost the least to acquire. The guide to law firm reputation management covers how that experience shows up in reviews.

Making the numbers trustworthy

KPIs are only as good as the records behind them. Every inquiry needs a source recorded at the time it arrives, every stage change needs a date, and everyone needs to define terms the same way. If one person counts a voicemail as contact and another does not, the contact rate means nothing. A well-kept case management system or CRM makes this much easier; the guide to law firm CRM explains what to look for.

Watch for numbers that look good for the wrong reason. A sign rate that rises because intake stopped answering hard calls, or a cost per case that falls because cases were counted before they were actually signed, will mislead you.

How often to look

Review intake numbers weekly, because problems there cost cases immediately and are usually quick to fix. Review marketing and case work monthly. Review fees and source economics quarterly, because injury cases take long enough that shorter windows are mostly noise. Compare each period with the same period before, and look for changes rather than reacting to a single number.

The short version

Pick a few numbers at every stage of a case: speed to contact, contact rate and sign rate at intake; cost per signed case and source mix in marketing; time to milestones and caseload during case work; and fee per case and time to fee at the end. Record sources and dates consistently, define terms the same way across the firm, and review each group on a schedule that matches how fast it changes.
