Your intake team signed the case. The retainer is executed. Then, three weeks later, liability review kills it — and every dollar spent to generate that lead is gone. Multiply that by 15% of your monthly signed caseload and you have a quiet drain that never shows up on any vendor invoice.
Withdrawal rate is one of the most tracked metrics in PI operations and one of the least connected to marketing data. Here are the benchmarks — and, more importantly, the framework to read what your withdrawal rate is really telling you about your lead sources.
What Is Withdrawal Rate?
Withdrawal rate measures the percentage of signed cases that are later withdrawn — retainer executed, but the case exited before resolution. Common causes: failed liability review, client non-cooperation, insufficient medical documentation, or economics that don't pencil out after initial records arrive.
Withdrawal Rate = (Withdrawn Cases ÷ Total Signed Cases) × 100
This is not the same as cases that settle below expectations (a case value problem) or leads that never sign (a conversion problem). Withdrawal rate is strictly post-sign attrition — cases your firm committed to and then had to exit.

Across the personal injury industry, withdrawal rates typically fall between 5% and 20%of signed cases. The spread reflects real differences in case type, intake rigor, and lead source quality — not noise.
Here is how to read the distribution:
- Under 5%:Exceptionally low. Usually signals rigorous pre-sign screening, a narrow case type focus, or — occasionally — a firm that is not withdrawing cases it should. Dig into case outcomes before celebrating.
- 5% to 10%:Strong. Firms at this level typically run thorough intake screening, work primarily with exclusive or referral sources, and enforce clear case acceptance criteria.
- 10% to 15%:Typical for mid-size PI firms buying from a mixed portfolio that includes aggregators. Not alarming on its own — manageable when cost per case economics are solid.
- 15% to 20%:Above average. Investigate whether specific lead sources, case types, or intake gaps are driving it before assuming it is firm-wide.
- Over 20%:A real problem. One in five signed cases never reaches resolution. That is wasted spend on leads, intake labor, and early case work across the board — and it almost always traces to lead quality, intake process, or both.
Why Withdrawal Rate Varies by Lead Source
The most important — and most underused — way to analyze withdrawal rate is by lead source. Your blended firm-wide number hides the variation that actually drives marketing decisions.
Once firms start tracking withdrawal rate by source, the pattern is consistent:
- Attorney and medical referrals:4% to 8%— these leads arrive pre-qualified with real relationships and verified case facts. The withdrawal floor is naturally lower.
- Google Ads and self-generated leads:8% to 15%— higher intent than aggregators, but no external pre-screening. Quality correlates directly with how tightly you control intake.
- Exclusive lead vendors:10% to 18%— wide variance by vendor. The best run 8% to 12%; the worst routinely exceed 20%. Vendor matters more than channel here.
- Shared aggregator leads:15% to 30%— lower pre-screening standards translate directly into higher post-sign attrition. The economics look fine until you account for withdrawal.
A firm tracking only a blended withdrawal rate is letting its worst vendors drag down its overall metrics — invisibly.

The Cost of Withdrawal
Withdrawal rate is not just an intake quality metric. It has direct financial consequences that most firms systematically undercount.
By the time a case is withdrawn, the firm has already absorbed:
- The marketing cost to generate the lead
- Intake labor to screen, qualify, and sign
- Early case work — client contact, records requests, liability research, possibly medical coordination
- Case management overhead — opening the file, entering it into your CMS, attorney assignment
For a typical auto case, the fully-loaded cost of an early withdrawal runs $500 to $2,000beyond the original marketing spend. At 15% withdrawal on 50 signed cases per month, that is 7 to 8 cases generating cost with zero revenue return — $5,000 to $15,000 in operational waste every month, before you account for what was spent to generate those leads in the first place.
Withdrawal Rate and Lead Source Evaluation
A vendor with a high withdrawal rate is not just delivering poor leads — it is creating a downstream operational burden that never appears on any invoice. This is the clearest argument against using cost per lead as your primary vendor evaluation metric.
A complete lead source evaluation framework covers all five layers:
- Cost per lead (what the vendor charges)
- Rejection rate at intake (what percentage get screened out)
- Conversion rate on accepted leads (what percentage sign)
- Withdrawal rate on signed cases (what percentage exit before resolution)
- Average settlement value on cases that do resolve
A vendor at 25% withdrawal likely produces worse cost per case than a vendor at 10% withdrawal — even when the cost per lead is substantially lower. Without withdrawal rate by source, that calculation is simply invisible.
When to Take Action on Withdrawal Rate
Not every spike warrants an immediate response. These are the patterns that do:
- A single vendor consistently above 20%— have a direct conversation about lead quality. Reduce budget allocation until the rate improves. Do not wait for a quarterly review.
- Firm-wide rate rising for three or more consecutive months— either lead quality is deteriorating across the board or intake is signing cases it should not. Audit both before assuming you know which.
- A new source significantly above your firm baseline within the first 90 days— do not assume it will self-correct. The withdrawal pattern from the first 60 to 90 days is highly predictive of long-term vendor performance.
- Wide variation between intake specialists on the same lead sources— this is a training problem, not a vendor problem. The fix is at the intake level, not the marketing budget.
Connecting Withdrawal Rate to the Marketing Attribution Loop
Most PI firms treat withdrawal rate as an intake or case management problem. The firms with the strongest marketing ROI treat it as an attribution signal.
When withdrawal rate by source sits alongside cost per lead, rejection rate, and conversion rate, you see each vendor's true cost per case — including the drag that high withdrawal rates add to otherwise acceptable economics. This is what lead source attribution makes visible. Vendors that look lean on cost per lead but produce 20%+ withdrawal rates are extracting money from your firm in ways that will never appear on an invoice.
The insight that changes vendor decisions — which grow, which get cut — is only available when you track intake outcomes to case resolution, not just to the signing date.
Benchmarking Your Own Withdrawal Rate
A few steps to make withdrawal rate actionable rather than just reportable:
- Calculate by lead source, not just firm-wide — the blended number hides what matters
- Track the reason for withdrawal (liability, medical, client non-cooperation) to separate intake problems from vendor problems
- Review on a rolling 90-day basis — monthly rates can be noisy given the lag between signing and withdrawal decisions
- Set source-specific thresholds, not a single firm threshold, since expected rates vary by lead type
