Industry benchmarks are useful — but only if you know how to translate them into targets that actually apply to your firm. A benchmark that says PI firms should achieve a $2,500 cost per case is meaningless if you're in a major metro market running TV campaigns for catastrophic cases. Your starting point, your market, and your channel mix all determine what “good” looks like for you.
This guide walks through a five-step process for taking industry benchmarks and converting them into quarterly performance targets your team can actually hit — and that your managing partners will find credible.
Establish Your Current Baseline
Calculate your actual cost per case, conversion rate, and lead pace by source before setting any targets. You cannot measure improvement without a starting point.
Identify Your Market Factors
Document your geography, case type mix, and competitive intensity. These factors determine where your firm should fall within benchmark ranges.
Apply Adjustment Factors
Adjust industry benchmarks up or down based on your market factors. A firm in a top-5 metro should expect 1.5–2x the cost per case of a mid-market firm.
Set Quarterly Improvement Targets
Target 10–15% improvement per quarter on your weakest metrics. Realistic improvement is compounding — 12% per quarter adds up to 40%+ over a year.
Build In Review Triggers
Define the thresholds that trigger mid-quarter action. If cost per case rises 20% on any source, or conversion drops below your floor, review immediately.
A five-step process for translating industry data into actionable goals.
Step 1: Establish Your Current Baseline
Before you set a single target, you need to know where you are right now. This sounds obvious, but most PI marketing directors we talk to cannot answer basic baseline questions with confidence: What is your blended cost per case? What is your cost per case by source? What is your intake conversion rate by source?
If you don't have these numbers, that's your first project — not target-setting. You need at least 90 days of clean data to establish a reliable baseline. Less than that, and your numbers are too volatile to build targets around.
Blended CPC
$___
All sources combined
CPC by Source
$___
Each vendor separately
Conversion Rate
___%
Lead to signed, by source
Lead Pace
___
Daily leads per $100K
Start with trailing 90-day averages. If you have six months of data, even better — use it to identify trends and seasonality. PI lead volume tends to be seasonal (summer peaks for auto accidents in most markets), and your baseline should account for that.
Step 2: Identify Your Market Factors
Three factors determine where your firm should reasonably fall within industry benchmark ranges. Document each one before attempting to set targets.
Geography
PI marketing costs vary dramatically by market. The top 10 most competitive PI advertising markets (Houston, Dallas, Los Angeles, Atlanta, Chicago, Phoenix, Las Vegas, Miami, San Antonio, Philadelphia) run 1.5x to 2.5x the cost per lead of mid-size and secondary markets. If you operate in a top-10 market, your cost per case benchmark should be adjusted upward accordingly.
Case Type Mix
A firm that handles 100% standard auto accident cases will have a fundamentally different cost structure than one handling a mix of auto, trucking, premises liability, and catastrophic injury. Higher-value case types cost more to acquire but generate more revenue per case. Your target cost per case should be weighted by case type.
Competitive Intensity
Beyond geography, some markets have specific competitive dynamics — a dominant firm spending $2M+/month, or a recent influx of national aggregators. If three new competitors entered your market in the last 12 months, your cost per lead has likely increased 15–25% regardless of your own campaign performance.
Step 3: Apply Adjustment Factors
Once you've documented your market factors, apply adjustment multipliers to the industry benchmark ranges. This is not an exact science — it's a structured way to arrive at targets that are realistic for your specific situation.
| Factor | Adjustment | |
|---|---|---|
| Top-10 metro market | Geography | 1.5x–2.0x base CPC |
| Mid-size market (pop. 500K–2M) | Geography | 1.0x–1.3x base CPC |
| Secondary/rural market | Geography | 0.7x–1.0x base CPC |
| Heavy catastrophic/trucking mix (30%+) | Case type | 1.3x–1.8x base CPC |
| Standard auto accident focus (80%+) | Case type | 1.0x base CPC |
| High-competition market (dominant spender) | Competition | 1.2x–1.5x base CPC |
| Moderate competition | Competition | 1.0x base CPC |
Multiply the base industry benchmark by these factors to set your adjusted target range.
Here's how this works in practice. If the industry benchmark for cost per case is $2,000 to $4,000, and your firm operates in Houston (1.8x geography factor) with a 30% trucking case mix (1.4x case type factor), your adjusted benchmark range is roughly $5,000 to $10,000. That sounds high — and it is. But it reflects the reality of your operating environment.
The goal is not to excuse high costs. It's to set targets that are achievable and then improve against them systematically.
Step 4: Set Quarterly Improvement Targets
With your adjusted baseline established, set improvement targets on a quarterly cadence. Annual targets are too distant to drive behavior. Monthly targets are too volatile to be reliable. Quarterly gives you enough data to measure real movement while maintaining accountability.
A realistic improvement rate for most PI firms is 10–15% per quarter on their primary optimization metric. That might be cost per case, intake conversion rate, or contact rate — pick the metric with the most room to improve and focus there.
Q1 Baseline
$4,200
Starting point
Q2 Target
$3,700
12% improvement
Q3 Target
$3,250
12% improvement
Q4 Target
$2,860
12% improvement
Starting from a $4,200 blended cost per case with 12% quarterly improvement.
Notice that 12% quarterly improvement compounded over four quarters reduces cost per case by 32% — from $4,200 to $2,860. That's meaningful. On a 100-case-per-month operation, that's $134,000 per month in marketing savings — or the budget to acquire 47 additional cases at the improved rate.
Not every quarter will hit the target. The point is to have a target — and to understand the gap when you miss it. Did you miss because a vendor underperformed? Because intake conversion dropped? Because you added a new, higher-cost channel? Each explanation leads to a different action.
Step 5: Build In Review Triggers
Quarterly targets are your cadence for strategic review. But you also need real-time triggers that prompt mid-quarter action when something goes off track. Set these thresholds for each lead source:
- Cost per case rises 20%+ from trailing average: Investigate within 48 hours. Check lead volume, lead quality scores, and intake conversion on that source.
- Conversion rate drops below your floor: Define a minimum acceptable conversion rate for each source. If Google Ads drops below 6%, or an aggregator drops below 2.5%, that triggers a vendor conversation.
- Daily lead pace drops 30%+ for 3+ consecutive days: Something changed — campaign paused, budget exhausted, or vendor issue. Don't wait for the weekly report.
- New vendor's 60-day cost per case exceeds 1.5x your target: Every new vendor gets a 60-day trial. If cost per case at day 60 is more than 50% above your adjusted target, it's time for a serious performance conversation.
Making This Sustainable
The biggest risk with a benchmarking-to-targets process is that it becomes a one-time exercise that nobody revisits. To make it stick, build it into your operating rhythm:
- Weekly: Review lead pace and conversion rate against targets. Flag any trigger breaches.
- Monthly: Update trailing cost per case by source. Identify which sources are trending toward or away from targets.
- Quarterly: Full benchmark review. Reset targets for the next quarter based on actual performance. Present results to partners.
The firms that get the most out of benchmarking are the ones that treat it as an ongoing practice, not a one-time analysis. Each quarter, you have better data, tighter targets, and a clearer picture of what's working.
