How Much Should a Personal Injury Firm Spend on Marketing?
Budget Benchmarks, Allocation Frameworks, and the Math Behind the Number
This is the question every managing partner asks and every marketing director dreads — because without attribution data, the answer is always a guess. “How much should we spend?” only has a real answer when you can tie every dollar to a signed case. This guide gives you the benchmarks, the framework, and the math to set a budget you can defend.
Industry Data
Marketing Budget Benchmarks by Firm Size
These ranges reflect what PI firms at each revenue tier typically invest in marketing. Use them as orientation, not prescription — your optimal budget depends on your growth targets and cost per case data.
| Firm Revenue | Monthly Budget | % of Revenue | Context |
|---|---|---|---|
| Under $5M | $15K – $50K/mo | 10 – 15% | Building awareness, limited vendor mix, heavy reliance on referrals |
| $5M – $15M | $50K – $150K/mo | 8 – 12% | Scaling paid channels, 5–8 active vendors, dedicated marketing hire |
| $15M – $40M | $150K – $400K/mo | 7 – 10% | Multi-market campaigns, full marketing team, brand investment starts |
| $40M+ | $400K – $750K+/mo | 6 – 8% | National presence, referral mix increases, brand spend scales up |
Why the percentage decreases as firms scale
Larger firms generate a higher share of cases through referral networks, brand recognition, and organic search — channels with near-zero acquisition cost. This lowers the overall marketing spend as a percentage of revenue, even as the absolute dollar amount increases significantly.
The Framework
How to Set a Marketing Budget Tied to Signed Case Targets
The right budget isn't a percentage of revenue — it's the amount required to hit your signed case targets at a profitable cost per case. Work backward from revenue goals.
Define Your Revenue Target
Start with the number your managing partner cares about. If the firm targets $12M in new case revenue from marketing this year, that’s $1M per month.
Calculate Cases Needed
Divide target revenue by your average fee per case. If your average contingency fee is $15,000 per case, you need 67 signed cases per month from marketing ($1M ÷ $15K).
Estimate Leads Needed Per Source
Work backward from signed cases using each source’s historical conversion rate. If Google Ads converts at 8%, you need 125 Google Ads leads to produce 10 signed cases. If a lead vendor converts at 12%, you need 42 leads for 5 signed cases.
Calculate Spend Per Source
Multiply leads needed by cost per lead for each source, or use your historical cost per case data directly. If Google Ads historically produces signed cases at $3,200 CPC, 10 cases costs $32,000. Sum all sources for your total monthly budget.
Worked Example
Mid-size firm targeting $12M/year in marketing-sourced revenue
Revenue target: $1,000,000 / month
Avg. fee per case: $15,000
Cases needed: 67 / month
67 signed cases × $15,000 avg. fee = $1,005,000 revenue on $145,200 spend. That's a 6.9x return on marketing investment.
Portfolio Strategy
How to Allocate Budget Across Channels
Think of your marketing budget like a portfolio. Diversification protects you from single-source risk. Concentration on proven performers maximizes returns. The right mix balances both.
50 – 60%
Proven High-ROI Channels
Sources with 3+ months of cost per case data below your break-even threshold. These have earned your dollars. Scale them until you see diminishing returns.
20 – 30%
Testing & Growth Channels
New vendors, new ad platforms, new geographies. Test with enough budget to generate meaningful data (at least 30–60 days and 50+ leads) before judging performance.
10 – 20%
Brand & Organic
SEO, content marketing, community sponsorships, and brand campaigns. These build long-term pipeline at low cost per case, but take 6–12 months to show results.
Why diversification matters
Firms that rely on a single vendor for more than 40% of their signed cases are one algorithm change, one vendor pricing increase, or one quality decline away from a revenue crisis. Spread your budget across 5–8 sources so that no single vendor can disrupt your pipeline.
Channel Allocation
Recommended Budget Split by Channel
For a $150K/month PI marketing budget, this is a defensible starting allocation. Adjust based on your actual cost per case data — this is orientation, not prescription.
$150K
Monthly Budget
Percentages reflect industry norms for mid-market PI firms. Adjust based on your measured cost per case by source.
| Channel | Typical Allocation | Time to Data | Best For |
|---|---|---|---|
| Google Ads (Search + LSA) | 30 – 40% | 30–60 days | High-intent buyers ready to call now |
| Lead Vendors | 20 – 30% | 60–90 days | Volume + case diversity at predictable CPC |
| TV / Broadcast | 10 – 20% | 90–180 days | Brand awareness + high-value case types |
| SEO & Content | 8 – 12% | 6–18 months | Long-term lowest CPC channel when mature |
| Social / Meta Ads | 5 – 10% | 30–60 days | Retargeting, mass tort, brand recall |
| Pay-Per-Call | 5 – 8% | 30–60 days | Surge capacity, supplemental volume |
Allocation follows performance, not convention
These percentages are a starting framework for firms without channel-level cost per case data. Once you have 90+ days of measured CPC by source, rebuild your allocation from scratch using actual performance — your numbers will look different, and they should.
By Revenue Tier
What Firms Actually Spend at Each Revenue Level
Marketing spend scales with revenue — but not linearly. Here are the budget and cost per case benchmarks that define performance at each tier.
Under $5M Revenue
$15K–$50K
Monthly marketing budget
$5M–$15M Revenue
$50K–$150K
Monthly marketing budget
$15M–$40M Revenue
$150K–$400K
Monthly marketing budget
$40M+ Revenue
$400K–$750K+
Monthly marketing budget
Ranges reflect surveyed PI firms. Firms tracking cost per case with attribution tools consistently outperform firms relying on vendor-reported data.
The trend on CPC is meaningful: larger firms achieve lower cost per case not because they spend less, but because they have more attribution data, stronger intake operations, and higher brand recall that improves conversion rates at every stage of the funnel. Firms under $5M that invest in tracking early compress this learning curve significantly.

Budget vs. Actual: Why Tracking Variance Matters
Most firms set a marketing budget in January and don't revisit it until the next fiscal year. By then, months of budget have been misallocated — overspending on declining vendors and underspending on sources that could have delivered more cases.
Budget variance tracking is the discipline of comparing what you planned to spend on each source to what you actually spent, and then comparing both to the cases produced. It turns your budget from a static document into a living performance tool.
Over Budget
If a vendor is over budget but delivering cases below your break-even CPC, that's a good problem — they're performing and you should consider increasing the budget formally. If they're over budget andabove your CPC target, that's a red flag requiring immediate vendor conversation.
Under Budget
Under budget usually means the source isn't scaling. Either the vendor can't deliver the volume you planned for, or your campaigns aren't spending at capacity. Both require investigation. Unspent budget on a proven source is missed opportunity.
What to Track Monthly
Planned vs. Actual Spend
By source, by month. Flag any variance greater than 15%.
Cases vs. Target
Signed cases per source versus the target you set when allocating budget.
CPC vs. Threshold
Cost per case by source versus your break-even CPC. Green, yellow, or red.
Channel Performance
Which Channels Deliver the Best Cost Per Case?
Not all channels perform equally at all budget levels. Here is how median cost per case compares across channels for mid-market PI firms spending $100K–$300K per month. Lower CPC = more cases for the same dollar.
Based on industry benchmarks for PI firms spending $100K–$300K/month. Actual CPC varies significantly by market, intake quality, and campaign management. SEO CPC reflects mature programs (18+ months).
What this chart does not tell you
CPC benchmarks are averages — and averages hide the variance that matters most. A Google Ads campaign managed by a specialist in PI can outperform any lead vendor. A lead vendor with poor quality control will underperform every paid channel. The number that matters is your cost per case by source, measured against your break-even threshold.
SEO & Content
Lowest long-run CPC — but requires 12–18 months to generate meaningful volume. Do not cut this budget when it is slow to start.
Lead Vendors
Most predictable CPC when tracked properly. Quality varies by vendor. Measure every vendor independently — never pool them.
TV / Broadcast
High CPC in isolation — but drives brand recall that improves conversion rates on other channels. Evaluate TV impact on total-portfolio CPC, not in isolation.
Partner Communication
The Budget Conversation With Your Managing Partner
Budget conversations fail when they're about feelings instead of math. Cost per case data gives you the math. Here's how to use it.
Instead of saying
“We need more budget.”
Say this
“We have three sources producing cases at $1,800 CPC against a $6,000 break-even. Adding $20K/month to each generates an estimated 33 additional cases — $495,000 in new fee revenue on $60,000 in spend.”
Instead of saying
“This vendor is working.”
Say this
“Vendor X has delivered 42 signed cases over the last quarter at $2,100 cost per case. Our break-even is $6,000. That's a 65% margin on acquisition cost. Here's the trend over six months.”
Instead of saying
“We should cut this vendor.”
Say this
“Vendor Y has run above our break-even CPC for three consecutive months. We gave them a 90-day improvement target in October. They missed it. Reallocating their $25K/month to Vendor X would produce an estimated 12 additional cases.”
Instead of saying
“Marketing needs to spend less.”
Say this
“Cutting $50K from our budget eliminates approximately 20 signed cases per month at current CPC rates. That's $300,000 in lost fee revenue. Instead, let me show you which sources are underperforming — we can reallocate, not reduce.”
The ROI frame changes everything
When you present budget requests with source-level cost per case data, the conversation shifts from “how much are we spending?” to “what return are we generating?” Marketing spend stops being a line item to cut and starts being capital to allocate.
Decision Framework
When to Increase vs. Decrease Your Marketing Budget
Scale Signals
- Multiple sources running below 60% of your break-even CPC
- Proven vendors have capacity to deliver more leads at current cost per case
- Your intake team has bandwidth to handle more volume without quality drops
- Firm is hiring attorneys and needs cases to fill capacity
- New market expansion with tested playbook from existing markets
Pull-Back Signals
- Majority of sources running above your break-even CPC for 3+ months
- Intake team is overwhelmed and conversion rates are dropping
- Firm is at attorney capacity and can't sign more cases
- Market saturation — increasing spend produces diminishing returns
- Cash flow constraints require preserving capital for case operations
The danger of cutting budget during slow periods
Slow intake months tempt firms to reduce spend. But lead generation has a 60–90 day lag to signed cases. Cutting budget in a slow month means fewer leads now, fewer signed cases in two to three months, and less revenue in six to twelve months. Unless your cost per case data shows your sources are genuinely failing, slow periods are for reallocating, not reducing.
Optimization Process
The Quarterly Budget Review Process
Most PI firms either never review their budget or make changes reactively after a bad month. A structured quarterly review gives you the data to make proactive, confident reallocation decisions before waste compounds.
Pull Baseline Data
- Export cost per case by vendor for the previous 90 days — not cost per lead, cost per signed case
- Identify each vendor's trajectory: improving, stable, or declining over the past three months
- Flag any vendor running more than 20% above your break-even CPC
- Note budget variance: which vendors over-delivered or under-delivered volume
Analyze & Score Vendors
- Rank every active vendor by cost per case (lowest to highest)
- Assign each vendor a status: Scale, Hold, or Cut — based on CPC vs. your break-even threshold
- For Scale vendors: determine whether they have capacity to deliver more volume at current CPC
- For Hold vendors: identify the one change (creative, geo, case type) that could move the needle
- For Cut vendors: calculate the budget freed and where it should be redeployed
Reallocate & Document
- Execute budget changes at the start of the month — not mid-month, which pollutes data
- Increase Scale vendors by 20–30% and set a 60-day checkpoint to verify CPC holds
- Pause Cut vendors and document the reason — you may want to re-evaluate in 6 months
- Set a new signed case target for the rebalanced portfolio
- Record the allocation decision and the data behind it for your managing partner report
Report & Reset
- Compare budgeted spend vs. actual spend vs. signed cases — by source
- Calculate portfolio-level cost per case: total marketing spend ÷ total signed cases
- Present the summary to your managing partner with before/after comparisons
- Document what worked, what failed, and what you are testing next quarter
- Set the budget for next quarter based on this quarter's data, not last year's numbers
The key principle
Review monthly. Reallocate quarterly. Decide with 90 days of data, not 30.
Single-month performance is noise. A vendor that had a bad February may have had a holiday lag in January intake. Three consecutive months of deteriorating cost per case is signal. Quarterly reviews give you enough data to act confidently without overreacting to short-term variance.
Monthly
Review CPC trends. Flag outliers. No budget moves.
Quarterly
Reallocate budget. Execute Scale / Hold / Cut decisions.
Annually
Rebuild the budget from scratch using the full year's CPC data.
Avoid These Errors
Common Budgeting Mistakes PI Firms Make
Setting a budget without signed case targets
A budget without a target is a cost, not an investment. If you don’t know how many signed cases you need from marketing, you can’t evaluate whether your spend is working. Start with the number of cases you need, then work backward to the budget required.
Allocating budget evenly across all vendors
Equal allocation ignores performance. A vendor producing cases at $1,500 cost per case should get more budget than one running at $5,000. Allocate based on proven cost per case, not fairness.
Not adjusting budget quarterly
Markets shift, vendors decline, new channels emerge. A budget set in January and untouched until December will waste money for months. Review and reallocate at least quarterly — monthly is better.
Ignoring the lag between spend and results
You spend in January, leads arrive in February, cases sign in March or April, and settlements close 6–18 months later. If you judge a budget by this month’s signed cases versus this month’s spend, you’re comparing mismatched data. Use cohort-based attribution to connect spend to outcomes correctly.
Budgeting based on last year instead of current performance
Last year’s budget was built on last year’s data. Vendor performance changes, markets shift, and your firm’s capacity evolves. Build next quarter’s budget on this quarter’s cost per case data, not on what you spent twelve months ago.
