How to Calculate Cost per Signed Personal Injury Case
Define signed-case acquisition cost without mixing incompatible sources, denominators, or attribution windows.
Cost per signed personal injury case is calculated by dividing defined marketing cost by signed cases attributed under a documented window, but the number is only useful when lead definitions, exclusions, duplicates, attribution rules, and pending statuses are consistent.

At a Glance
What this guide helps you decide.
Cost per signed personal injury case is calculated by dividing defined marketing cost by signed cases attributed under a documented window, but the number is only useful when lead definitions, exclusions, duplicates, attribution rules, and pending statuses are consistent.
Three things to retain
- The denominator matters more than the label on the report.
- Signed-case cost should include a visible attribution window and exclusions.
- A lower cost per lead can still produce worse economics if qualification or signed-case movement is weak.

Executive Takeaways

- A lower cost per lead can still produce worse economics if qualification or signed-case movement is weak.
Shared Definitions
Terms used in this guide
- Lead
- Any new contact before quality or fit is known.
- Qualified opportunity
- A screened contact matching the firm's defined intake criteria enough to proceed.
- Consultation
- A scheduled or completed review step, depending on the firm's reporting definition.
- Accepted case
- A case the firm elects to pursue after internal review.
- Signed case
- A retained matter with agreement status completed.
- Attributed case
- A signed case assigned to a source under declared attribution and window rules.
These terms are operational reporting definitions. They do not determine legal merit, case value, or whether a firm should accept a matter.
Key Decision
Calculate cost only after source cost, signed-case status, exclusions, duplicates, and attribution window are explicit.
Cost Metric Tree
- Cost per lead Defined source spend Non-duplicate leads
- Cost per qualified opportunity Defined source spend Qualified opportunities
- Cost per consultation Defined source spend Scheduled or completed consultations
- Cost per signed case Defined source spend Signed cases
- Attributed signed-case cost Channel or campaign cost Signed cases attributed to that source
Use the tree to choose the denominator that matches the decision: lead quality, intake movement, signed cases, or attributed economics.
Cost Metric Tree
A metric tree connecting spend, leads, qualified opportunities, consultations, signed cases, and attributed cost calculations.
Use the tree to choose the denominator that matches the decision: lead quality, intake movement, signed cases, or attributed economics.
Decision Tool
| Metric | Numerator | Denominator | Exclude | Primary caveat |
|---|---|---|---|---|
| Cost per lead | Defined source spend | Non-duplicate leads | Spam and test contacts | Lead count is not case quality |
| Cost per qualified opportunity | Defined source spend | Qualified opportunities | Wrong-fit contacts | Depends on screening consistency |
| Cost per consultation | Defined source spend | Scheduled or completed consultations | No-show status if excluded | Consultation definition must be explicit |
| Cost per signed case | Defined source spend | Signed cases | Pending and unattributed cases if excluded | Attribution window changes the answer |
| Attributed signed-case cost | Channel or campaign cost | Signed cases attributed to that source | Cross-source duplicates | Requires source and CRM discipline |
Use the tree to choose the denominator that matches the decision: lead quality, intake movement, signed cases, or attributed economics.
Formulae and Caveats
Calculations must keep their denominator attached
Cost per signed case
Calculation: Defined marketing cost divided by attributed signed cases
Inputs: Spend, signed cases, attribution window
Exclude: Brand-only spillover, duplicates, pending cases if not closed
Caveat: Never compare channels unless each uses the same definitions.
Qualified opportunity cost
Calculation: Defined marketing cost divided by qualified opportunities
Inputs: Spend, qualified opportunities
Exclude: Wrong-fit leads, spam, duplicates
Caveat: Useful earlier than signed-case reporting but still requires disposition quality.
Build The Denominator First
Before calculating cost per signed case, define what counts as signed, what remains pending, how duplicate contacts are merged, and how source attribution works when more than one touch exists.
Keep Source Cost Honest
Source cost may include media spend only or media plus management and production cost. Either method can be valid, but the report must label it consistently.
What Changes The Answer
The calculation changes when the firm changes attribution window, source cost scope, duplicate rules, signed-case status, pending-case treatment, or whether brand demand is included.
Legal, Ethics, Privacy, and Data-Quality Note
Marketing reporting is not legal advice.
This guide is written for marketing and operations decisions. It does not provide legal advice, does not determine legal merit or case value, and does not generalize one jurisdiction's rules to every firm. Any use of reviews, testimonials, advertising claims, tracking, or outcome feedback should be checked against applicable rules, platform policies, consent requirements, and the firm's own professional obligations.
What to Remember
The practical memory aid.
- The denominator matters more than the label on the report.
- A cost-per-case number can look precise while hiding pending matters, duplicate contacts, brand spillover, management cost scope, or inconsistent signed-case definitions.
- Next action: Lost opportunity should be quantified before the next spend decision.
False Precision In Case Economics

CliqSpark Perspective
CliqSpark prefers a transparent cost tree over a polished but fragile KPI. The number should invite better questions about source quality and operating constraints.
FAQ
Can cost per signed case be compared across firms?
Usually not cleanly. Different firms use different markets, case criteria, source mixes, operating costs, and attribution windows.
Should pending cases be counted?
Only if the report clearly labels them. Signed-case calculations should not silently mix signed and pending matters.
Is cost per signed case the same as ROI?
No. It is an acquisition efficiency metric. ROI also needs case economics, timing, and revenue assumptions that may not be knowable early.
