The Best Performance Metrics for Grading PI Lead Channels in 2026

Every PI marketing director tracks metrics. The question is whether you're tracking the right ones — the metrics that actually predict which channels will produce profitable cases six months from now, not just the ones that look good in a vendor report today.

This article ranks the seven most important performance metrics for grading PI lead channels in 2026, explains why each one matters, and defines what “good” looks like based on current industry benchmarks. If you're building a channel scorecard — or evaluating whether your current one is complete — start here.

1. Cost Per Signed Case

Why it's #1:Cost per signed case is the single metric that most directly connects your marketing spend to business outcomes. It answers the question every managing partner actually cares about: “How much did we pay to get this client?”

Cost per lead is an input metric — it tells you the price of attention. Cost per signed case is an outcome metric — it tells you the price of a client. Firms that optimize for cost per case instead of cost per lead consistently see 15–20% better marketing ROI within 90 days, because they stop funding sources that generate contacts but not cases.

What good looks like:Benchmarks vary significantly by case type and market. For motor vehicle accident cases in competitive metros, $1,500–$3,000 per signed case is a strong range. For premises liability or slip-and-fall, $2,000–$4,500 is typical. The key is not the absolute number — it's whether the cost per case produces a profitable return given your average settlement value.

2. Contact Rate

Why it matters:Contact rate is the percentage of leads your intake team can actually reach by phone, text, or email. It's the first quality gate — and it's often the one that separates real leads from database filler.

A vendor can send you 300 leads per month, but if your team can only reach 35% of them, your effective lead volume is 105. The other 195 consume call attempts, intake time, and follow-up sequences without ever converting. Contact rate exposes this hidden cost.

What good looks like:For PI lead vendors, a 55–70% contact rate on first-day attempts is solid. Below 45% is a red flag that suggests bad phone numbers, duplicate leads, or leads that were never genuinely interested. Live transfer sources typically achieve 80%+ because the lead is already on the phone.

3. Intake Conversion Rate

Why it matters:Intake conversion rate measures the percentage of contacted leads that become signed cases. While contact rate tells you whether leads are reachable, conversion rate tells you whether they're signable.

A channel with a 65% contact rate and a 12% conversion-of-contacted rate produces very different economics than one with a 50% contact rate and a 3% conversion rate. Conversion rate captures lead intent, case qualification, and how well a source's leads match your firm's practice areas and criteria.

What good looks like:For PI firms, a 4–8% overall conversion rate (leads to signed cases) is healthy across most channels. Top-performing Google Ads campaigns often hit 8–12%. Mass-market sources like TV and radio typically land at 2–4%. If a channel is below 2%, the cost per case math rarely works unless the cases are exceptionally valuable.

4. Case Severity Distribution

Why it matters: Two channels can produce identical conversion rates and similar cost per case — but if one delivers 70% soft tissue cases and the other delivers 40% moderate-to-severe injuries, the revenue difference is enormous. Severity distribution is what separates a channel that covers its costs from one that actually drives profit.

This metric requires connecting your marketing data to your case management data, which is why most firms don't track it. But it's often the factor that explains why two seemingly similar channels produce vastly different ROI.

What good looks like:A healthy channel for PI should show at least 25–35% of cases in the moderate-to-severe category. Channels that skew 80%+ toward minor soft tissue cases will struggle to justify their cost unless the volume is very high and the cost per case is very low.

5. Withdrawal Rate

Why it matters:A signed case isn't a settled case. Withdrawal rate — the percentage of signed cases that are later dropped, withdrawn, or closed without settlement — is a metric most firms track but rarely connect back to lead source. That's a mistake.

Some sources consistently produce cases that look good at signing but fall apart during litigation: clients stop cooperating, injuries don't substantiate, or the case facts don't hold up. If a channel has a 25% withdrawal rate while your firm average is 12%, that channel's true cost per settled case is significantly higher than its cost per signed case suggests.

What good looks like:A withdrawal rate below 15% is solid for most PI channels. Between 15–20% warrants investigation. Above 20% is a clear signal that the lead quality or case qualification process needs improvement at the source level.

6. Speed to Sign

Why it matters:Speed to sign measures the average number of days between lead arrival and case signing. It's both an efficiency metric and a quality indicator. High-intent leads from quality sources sign faster because they're genuinely motivated and properly qualified.

Speed to sign also affects your intake team's capacity. A channel where leads take an average of 14 days and 6 follow-up attempts to sign consumes three to four times more intake labor than one where leads sign in 3 days with 2 follow-ups. That labor cost rarely shows up in the marketing budget — but it's real.

What good looks like:For PI cases, 2–5 days from first contact to signed retainer is excellent. 5–10 days is acceptable. Beyond 10 days, the lead is either low-intent, being contested by competitors, or not well-matched to your firm. Channels averaging 14+ days should be evaluated for whether the intake effort is justified by the case value.

7. Settlement Value Per Case

Why it matters: Settlement value is the ultimate revenue metric — it tells you what a channel is actually worth in dollars, not just cases. Two channels producing cases at $2,500 cost per case are not equivalent if one averages $35,000 settlements and the other averages $120,000.

The challenge with settlement value is the time lag. PI cases take 6–18 months (sometimes longer) to settle, so you won't have this data for new channels immediately. But for established channels with 12+ months of history, settlement value per case is the metric that completes your ROI picture.

What good looks like:Benchmarks are highly case-type dependent. For MVA cases, $40,000–$80,000 average settlement is a reasonable range for most PI firms. The metric to watch is the ratio: settlement value divided by cost per case. A ratio above 15:1 indicates a strong channel. Below 8:1 means the economics are tight.

Building Your Channel Scorecard

You don't need all seven metrics from day one. Start with the top three — cost per signed case, contact rate, and conversion rate — because those are available from your existing intake data and spend records. Add severity, withdrawal, and speed-to-sign as you connect your case management data. Add settlement value once you have 12+ months of history on a channel.

The goal is a single scorecard where every active channel gets graded on the same criteria. When your Google Ads channel scores 81 and your mass tort vendor scores 37, the budget conversation writes itself.

A revenue intelligence platform calculates these metrics automatically by connecting your lead data, case data, and spend data in one place. But the framework works regardless of how you calculate the numbers. What matters is that you're measuring the right things — and these seven metrics are the ones that actually predict channel profitability for PI firms in 2026.
