MVA Lead ROI Calculator: From CPL to Cost Per Signed Case

MVA lead ROI is calculated by comparing the total cost of lead acquisition (cost per lead multiplied by volume) against the revenue generated from signed cases. The key metric is cost per signed case, not cost per lead. An exclusive lead at $300 with 10% conversion produces a $3,000 cost per signed case, while a $100 shared lead at 7% conversion produces a $1,428 cost per signed case, but requires 3x the intake volume.

Most PI firms track cost per lead. Smart firms track cost per signed case. The difference between those two numbers is where real money gets made or lost, and it changes everything about how you evaluate lead vendors, negotiate pricing, and allocate your marketing budget.

We run the math on thousands of MVA leads every month through Claim Supply. The firms that consistently outperform their competitors aren't the ones buying the cheapest leads. They're the ones who understand exactly what each signed case costs them after conversion, compliance, and intake overhead get factored in. This guide walks you through that calculation step by step, so you can run it yourself with your own numbers.

TL;DR: Exclusive MVA leads at $300 with a 15% conversion rate produce a 6.6:1 ROI based on a $40,000 average car accident settlement at 33% contingency ($13,200 per case). Your break-even conversion rate is just 2.3%. When you add lifetime value from client referrals (0.5 per client over 3 years), the effective ROI jumps to 9.9:1. Use the calculator below to run your own numbers. Stop comparing CPL. Start comparing cost per signed case.

The Four-Step ROI Calculation

Every lead ROI calculator boils down to four numbers: total spend, conversion rate, revenue per case, and the ratio between revenue and spend. Let's walk through each step with real data, then you can swap in your own figures.

Step 1: Calculate your total lead spend.
Start with the basics. How many leads are you buying per month, and what are you paying per lead? For this example, we'll use 100 exclusive MVA leads at $300 each. Total monthly spend: $30,000. This is a realistic volume for a mid-size PI firm running leads across 2-3 states.

Step 2: Apply your conversion rate.
Your lead-to-signed-case conversion rate determines how many of those 100 leads become paying clients. For exclusive web leads, the industry range is 10-15% when contacted within 60 seconds (Velocify). We'll use 10% as a conservative baseline. That gives you 10 signed cases from 100 leads.

Step 3: Calculate your gross revenue.
The average car accident settlement in the United States is $37,249 (Brown & Crouppen, 2025). At a standard 33% contingency fee, you earn $12,292 per case. Multiply that by your 10 signed cases: $12,292 x 10 = $122,920 in gross revenue.

Step 4: Calculate your ROI.
Divide revenue by spend: $122,920 / $30,000 = 4.10. Your return on investment is 4.1:1, or 410%. For every dollar you spend on leads, you generate $4.10 in contingency fee revenue.

That number looks strong. But it depends entirely on your conversion rate holding at 10%. Push to 15%, and your ROI jumps to 6.1:1. Drop to 5%, and you're at 2:1. The spread between a well-run intake operation and a sloppy one is often $100,000+ per year on the same lead volume.

Where Your $30K Investment Actually Goes

Raw ROI is useful, but it doesn't tell you the full story. When you spend $30,000 on MVA leads, that money splits across several buckets: revenue from signed cases, sunk cost from unconverted leads, compliance expenses, and intake overhead. Understanding the breakdown helps you find where the waste is.

Here's how a typical $30,000 monthly lead investment distributes:

The biggest bucket is revenue at $122,920 from your 10 signed cases. The second largest is the sunk cost of 90 unconverted leads at $300 each ($27,000). Compliance runs about $1,500 for TrustedForm certificates, DNC scrubbing, and call recording. Intake overhead adds roughly $1,050 in staff time for 100 calls.

Here's the important takeaway: your unconverted leads represent the single biggest opportunity for improvement. Moving from 10% to 15% conversion doesn't cost you an extra dollar in lead spend. It just means your intake team contacted faster, followed up more aggressively, or qualified better. That 5-point improvement turns 5 extra leads into signed cases, adding $61,460 in revenue for free.

ROI by Lead Type: Side-by-Side Comparison

Not all leads deliver the same return. The chart below compares the four major lead types on cost per signed case and ROI, using national averages for pricing and conversion rates. The numbers tell a story that surprises most buyers: the cheapest lead per unit is rarely the cheapest lead per case.

Shared leads show the highest raw ROI (8.6:1) because the upfront cost is so low. But that number is deceptive. It assumes you're the first firm to call and that your intake team can outcompete 3-4 other firms racing for the same prospect. In practice, most firms see shared lead conversion closer to 5% than 7%, which drops ROI to 6.1:1. It also ignores the higher intake overhead of calling leads who've already hired a competitor.

Exclusive leads at 4.1:1 are the most predictable. Your conversion rate depends on your own intake speed, not on beating competitors to the phone. That predictability matters when you're building a monthly budget.

Break-Even Analysis: The Number You Need to Know

Every lead buyer should know their break-even conversion rate. This is the minimum percentage of leads you need to convert before your spend starts generating profit instead of losses. It's the single most important number in your lead ROI calculator because it tells you how much room for error you have.

The formula is straightforward: Break-even conversion = Cost per lead / Revenue per case.

With $300 exclusive leads and $12,292 in average fee revenue per case: $300 / $12,292 = 2.44%. You need to sign roughly 1 out of every 41 leads just to cover your spend. Anything above 2.4% is profit.

Here's what break-even looks like across different CPL levels:

Even at $500 per lead, you only need 4.1% conversion to break even. Most firms with competent intake teams convert at 3-4x their break-even rate, which means the margin of safety is substantial. The real danger isn't buying leads that are too expensive. It's buying leads where you can't control the conversion variables, like shared leads where speed-to-contact determines everything.

If your conversion rate is hovering near break-even, the problem is almost never the leads. It's your intake process. Slow speed-to-contact, untrained intake staff, and missing follow-up sequences are the most common conversion killers we see on the Claim Supply platform.

Lifetime Value: The Hidden Multiplier

First-touch ROI only tells part of the story. Signed MVA clients don't just generate one case fee. They refer friends, family members, and coworkers who get into accidents down the road. Smart firms track this lifetime value because it fundamentally changes the math on what you should pay per lead.

The industry benchmark: each signed MVA client generates an average of 0.5 referrals over a 3-year period. That means for every 2 clients you sign, one of them will send you another case, and that referred case costs you nothing in lead acquisition.

Let's update the ROI calculation with lifetime value factored in:

• First-touch revenue: 10 signed cases x $12,292 = $122,920
• Referral cases (3-year horizon): 10 x 0.5 = 5 additional cases
• Referral revenue: 5 x $12,292 = $61,460
• Total lifetime revenue: $122,920 + $61,460 = $184,380
• Lifetime ROI: $184,380 / $30,000 = 6.1:1

Your 4.1:1 first-touch ROI becomes 6.1:1 when measured over 36 months. That 50% increase comes entirely from client referrals you didn't pay for. Firms that build referral systems into their client experience (thank-you calls at case close, anniversary check-ins, referral incentive programs) push that 0.5 referral rate closer to 0.8 or even 1.0, which makes the ROI calculation even more favorable.

This is also why the cheapest CPL isn't always the best strategy. If exclusive leads produce higher-quality cases that settle for more and generate more referrals, the $300 exclusive lead can outperform the $100 shared lead by 2-3x on a lifetime basis, even though the upfront cost is triple.

Cost Per Signed Case vs. Cost Per Lead: Why It Matters

This is the mistake we see more than any other. Firms fixate on CPL (cost per lead) and ignore CPSC (cost per signed case). They'll switch from a $300 exclusive vendor to a $150 shared vendor, celebrate their "50% CPL reduction," and then wonder why revenue dropped.

Here's the math side by side:

Shared leads show a lower cost per signed case ($1,428 vs. $3,000). But look at total profit from the same 100 leads: $92,920 for exclusive vs. $76,044 for shared. Exclusive leads still produce more profit because the conversion rate is higher, even though the per-case cost is steeper.

The lesson: CPL is a vanity metric. CPSC is a useful efficiency metric. But total profit from a given lead volume is the only number that actually matters for firm growth. Don't optimize for the cheapest cost per case. Optimize for the highest total return on a fixed budget.

Putting It All Together

Here's your lead ROI calculator checklist. Run these numbers with your own data every month:

1. Calculate total spend: Leads purchased x CPL. Include compliance costs ($0.15-$0.50/lead for TrustedForm) and intake overhead.
2. Track actual conversion: Leads delivered vs. cases signed. Break it down by lead type and vendor if you're buying from multiple sources.
3. Compute cost per signed case: Total spend / signed cases. Compare this across vendors and lead types, not CPL.
4. Measure revenue per case: Actual settlement amounts x contingency percentage. Don't use averages if you have your own data.
5. Calculate ROI: Total revenue / total spend. Your floor should be 4:1. Target 6:1 or higher.
6. Factor lifetime value: Track referrals from signed clients over 12, 24, and 36 months. This number only grows.

The firms generating the highest returns aren't buying the cheapest leads. They're buying the most predictable leads, running tight intake operations, and measuring every step from delivery to signed retainer. If you're spending $10K+ per month on leads and you're not tracking cost per signed case, you're flying blind.
