When PI firm managing partners compare notes on intake performance, they almost always talk about total cases signed. Rarely do they talk about conversion rate — the percentage of inbound calls that result in a signed retainer. And almost never do they have the data to compare conversion rates by case type, by lead source, or by individual specialist.
That lack of benchmarking data keeps firms operating blind. You might think 7% conversion is normal (it is — it’s the industry average). You might also think it’s acceptable (it’s not — top performers convert at 12-15%, which means the average firm is leaving half its potential revenue on the table).
This post provides the benchmark data PI firms need to evaluate their intake performance — and identify where the biggest improvement opportunities are hiding.
Overall Conversion Benchmarks
Based on industry data and Speed.ai’s analysis across our customer base, here’s where PI firms typically fall. Below average is under 7% — these firms are losing significant revenue at intake, often due to untrained specialists, no QA process, or poor after-hours coverage. Average sits at 7-9%, where most PI firms operate. Above average is 10-12%, reflecting firms with dedicated intake teams, some form of performance management, and reasonable follow-up processes. Top performers hit 12-15%, with trained specialists, structured coaching, and systematic lead recovery. Elite programs exceed 15%, combining exceptional specialist talent with AI-powered QA and Lead Rescue.
Benchmarks by Case Type
Not all case types convert at the same rate, and comparing your overall number to a single benchmark misses important nuance.
Auto accidents (standard): 8-12% conversion. High volume, moderate competition. Callers are often comparing firms, so urgency creation and rapid follow-up matter most.
Trucking accidents: 10-15%. Lower volume but higher case values. Callers tend to be more motivated because the injuries are typically more severe. Specialists who recognize commercial vehicle indicators convert at the top of this range.
Slip-and-fall / premises liability: 5-8%. Lower conversion because liability is often less clear-cut to the caller, and injuries tend to be less severe on average. Specialists need strong empathy skills to keep these callers engaged.
Medical malpractice: 3-6%. Complex cases that often require attorney review before the firm can commit. The intake challenge here is keeping the caller warm through a longer evaluation period.
Catastrophic injury: 15-25%. When someone calls with a spinal cord injury, severe TBI, or amputation, they’re highly motivated to retain counsel. The specialist’s job is primarily to not lose the case — which, unfortunately, still happens more than it should.
Benchmarks by Lead Source
The channel that generates the lead has a massive impact on expected conversion rate — which is why marketing ROI analysis that stops at cost-per-lead is incomplete.
Referrals: 25-40% conversion. The highest-converting source by far. The caller already has social proof and trust. If your firm isn’t maximizing referral conversion, you’re wasting your best leads.
Google Ads: 7-15%. Wide range depending on keyword targeting and ad quality. High-intent keywords (“lawyer near me after car accident”) convert at the top. Broad match terms convert at the bottom.
SEO / organic: 5-10%. Callers from organic search tend to be earlier in the research process and may be comparing more firms.
Third-party leads (mass tort aggregators, lead vendors): 3-7%. Lowest conversion because the lead was often sold to multiple firms simultaneously. Speed matters more here than anywhere else — but quality still determines who signs.
The Hidden Benchmark: Specialist Variance
The most important benchmark most firms don’t track is the gap between their best and worst intake specialist. In a typical firm, the top specialist converts at 2x to 4x the rate of the bottom specialist. They’re taking calls from the same lead pool, at the same firm, with the same scripts — and producing wildly different results.
This gap is your single largest controllable revenue variable. Making it visible through per-specialist performance tracking is the fastest path from average to above-average conversion rates. You don’t need more leads. You need your bottom performers to close the gap with your top performers.
