Running a law firm can feel like juggling a dozen tasks—serving clients, managing staff, ensuring smooth billing, and hopefully adding new business. With so many moving parts, it’s easy to lose track of where your time and money actually go. Key Performance Indicators (KPIs) help cut through the chaos by showing how well your firm is functioning and where you might be missing opportunities. By identifying and tracking the right KPIs, including financial KPIs, you can shape your strategy, boost profitability, and ultimately serve your clients more effectively.

For now, let’s explore some core KPIs that many firms rely on. You don’t have to tackle them all at once; focus on those that match your goals—maybe you want to improve billing or gain more cases. Once you gather some data, you can spot trends, test new ideas, and see what truly boosts performance. Keep reading to learn more!

Billable Hours vs. Non-Billable Hours

Measuring how much time your lawyers and staff spend on actual billable work is often eye-opening. If attorneys devote too many hours to tasks that don’t bring in revenue—like administrative chores or marketing—they might need additional support to free them up for client-facing duties. This KPI also gives you a clue about your revenue potential. When you see consistently low billable hours, you might be missing out on income that your firm could be earning. Tracking hours daily or weekly (instead of monthly) can help you notice smaller trends and make adjustments faster. A software tool for time tracking or practice management can remove the guesswork and clarify who’s spending time where, ultimately improving law firm profitability.

Realization Rate

The realization rate is the fraction of billed hours that actually get paid by clients. You might bill 100 hours but only receive payment for 90 because of discounts, write-offs, or client disputes. This KPI helps you see if you’re monetizing your legal work fully or leaving money on the table. A low realization rate can hint that you’re billing at rates clients think are too high, that you’re discounting more than necessary, or that your cases tend to run over budget. Try looking at realization by practice area or individual attorney; you may discover one team member who writes off more hours or offers too many “courtesy” discounts. Aim for 90% or higher, and if you’re falling short, investigate why you’re missing those extra hours of payment. Improving your realization rate is crucial for your firm’s success.

Utilization Rate

Utilization rate measures the percentage of an attorney’s available time that goes toward billable hours. If someone works 40 hours a week and bills 30 of them, their utilization is 75%. This high-level view helps you see if attorneys are overwhelmed or underused. If your target is 70-80% but some attorneys hover at 50%, they might be dealing with excessive administrative work, or they’re not getting enough client assignments. If someone’s at 95% or higher, that’s great for revenue in the short term, but it could lead to burnout. Breaking utilization down by individual or department can clarify workload distribution and signal if you need to hire, shift tasks, or lighten someone’s load.

Average Case Value

Tracking the average dollar amount per case or matter reveals where your most profitable work lies — if you intend to track law firm KPIs, this is an important one. If you notice that personal injury cases bring in far more revenue than family law matters, you might double down on marketing personal injury services. Or if certain cases routinely exceed expected budgets, you can adjust how you quote fees or manage tasks. To find this KPI, divide the total revenue from a practice area by the number of matters handled in a set timeframe. Keep in mind that a single large case can skew averages, so it helps to also view the case distribution for valuable insights.

Client Acquisition Cost (CAC)

Client Acquisition Cost (CAC) is the total marketing and sales expense to secure each new client — as far as key performance indicators go, it is extremely important to assess when it comes to marketing your law firm. If you spend $5,000 on ads and sign 10 new clients, your CAC is $500 per client. This metric helps you know if your marketing dollars pay off or if you’re overspending. You can compare it to the average case or lifetime client value to see if it’s sustainable. If your CAC is $1,000 but you routinely earn $2,000 per client, you’re in decent shape. If you earn less, you might need to refine your marketing approach. Make sure to include all relevant costs—advertisements, referral fees, networking event fees, and even the staff time devoted to marketing. Tracking your CAC is essential to measure success and ensure your marketing strategy is effective.

Collection Rate

Tracking KPIs, such as the collection rate, is crucial for law firms to enhance data-driven decision-making and overall firm health. The collection rate is the percentage of billed fees that you actually receive. It focuses on whether the client follows through after getting an invoice. Even if you bill on time, you could face slow-paying or non-paying clients, hurting your cash flow. If your collection rate is below 90%, it’s time to examine potential issues. Maybe your invoices aren’t clear enough, maybe you send bills too infrequently, or you might need more structured follow-ups. Looking at your accounts receivable (AR) aging can show how overdue certain invoices are—bills older than 90 days can become much harder to collect. Automating invoice reminders or requiring retainers might help raise the collection rate.

WIP (Work in Progress) and AR (Accounts Receivable) Days

WIP is the unbilled work you’re doing right now, and AR is the money you’ve billed but not yet collected. Calculating WIP and AR days reveals how many days of revenue are tied up in these categories. Long WIP days might mean you take too long to invoice after doing the work, effectively delaying payment. High AR days can show that clients have too much time to pay or that you aren’t following up on overdue invoices. Keeping these numbers in check helps stabilize your cash flow. Some firms aim for no more than 45 days in AR. If it creeps higher, see if you can shorten your billing cycle to weekly or bi-weekly, or offer discounts for quicker payments.

Client Satisfaction and Retention

Although financial metrics get the spotlight, client happiness ultimately drives repeat business and referrals, which are crucial for a law firm’s success. Satisfied clients often return for additional legal needs and send new clients your way. Unhappy ones might leave negative reviews or share bad experiences with friends. You can assess satisfaction by sending short feedback forms after matters close, or by encouraging online reviews. If you keep hearing complaints about slow communication, maybe you need more regular check-ins or an online client portal. By acting on client feedback, you not only improve your reputation but also make internal changes that can boost efficiency.

Lead Conversion Rate

Lead conversion is the percentage of prospects who go from inquiry to signed engagement. It’s especially relevant if your law firm invests in marketing campaigns or offers free initial consultations. A low conversion rate may mean your intake process could use refining, or that you’re attracting leads who aren’t truly a match for your services. Tracking leads by source also helps identify which marketing channels deliver serious prospects and which ones bring tire-kickers. Looking at conversion by attorney or intake specialist can show who’s best at persuading clients to sign, allowing you to share winning techniques across the firm.

Employee Satisfaction or Turnover

Law firms rely heavily on their attorneys and staff as the engine of their operations. High turnover can disrupt client relationships, spark extra hiring costs, and drag down morale. Measuring employee satisfaction can give you a heads-up if people are burning out or feeling undervalued. This KPI may not show up in your financial statements, but it can indirectly affect everything from productivity to client retention. You might track how many employees leave each year, conduct exit interviews to pinpoint issues or run simple, anonymous surveys to gauge staff attitudes. If you see a rising turnover rate, consider whether pay, workload, or culture needs attention.

Marketing ROI

Valuable insight into marketing ROI goes beyond just counting leads. It examines how much revenue you gain compared to what you spend. If a social media ad campaign costs $1,000 and yields $3,000 in new business, you’re seeing a positive return. If you’re getting only $500 from the same investment, you might reallocate funds. Knowing this figure helps you place your limited marketing resources where they’ll do the most good. Break down marketing spend by channel—maybe you have Google Ads, local sponsorships, or billboard campaigns—and track the resulting clients and fees. Reviewing these metrics periodically lets you tweak or scrap campaigns that don’t deliver.

Net Promoter Score (NPS)

Net Promoter Score (NPS) measures how likely clients are to recommend your legal practice. They rate your firm from 0 to 10, with 9-10 as “promoters,” 7-8 as “neutral,” and 0-6 as “detractors.” Subtract the percentage of detractors from the percentage of promoters, and you get your NPS. A high NPS means loyal clients who might refer new business. A low one suggests dissatisfaction or communication issues you need to fix. Keep NPS surveys short and follow up personally with anyone who rates you low to better understand their complaint.

Bringing KPIs into Your Workflow

No single list of KPIs works for every firm, so pick the ones that match your current objectives. Maybe you want to boost revenue by focusing on the realization rate and collection rate. Or perhaps you’re worried about staff burnout, making utilization rate and employee satisfaction top priorities. Once you’ve chosen your KPIs, schedule regular reviews—monthly or quarterly—and assign someone to collect the data. If you see utilization rates dropping, for instance, you can take corrective action right away. Having tangible data lets you replace hunches with informed decisions. Using a practice management system to track these KPIs also helps you celebrate real progress, whether that’s a higher collection rate or a better NPS.
