What a Personal Injury Case Is Worth (and How That Sets Your Marketing Budget)

Your marketing budget should start with what a signed case is worth to your firm, not with what a lead costs. Most owners do it backward. They look at a cost per lead, decide it feels high or low, and adjust spend on gut feel. That is how you end up overpaying for cheap leads that never sign and starving the channels that bring real cases. The honest method is simpler: estimate your average case value, decide what share of the fee you are willing to reinvest, and work down to a defensible cost per signed case. Everything else follows from that one number.

Start with case value, because it varies more than you think

A personal injury case is not one product. The fee on a soft tissue MVA case and the fee on a wrongful death claim can differ by an order of magnitude, and your budget math has to respect that.

Rough, typical ranges (yours will differ by venue and firm):

• Minor soft tissue MVA: a few thousand dollars in fee on a modest settlement.
• Moderate MVA with clear injuries: low five figures in fee.
• Serious or catastrophic injury, trucking, or commercial vehicle: well into five or six figures in fee.
• Wrongful death and catastrophic or TBI cases: the largest fees, but lower volume and longer cycles.

The point is not the exact numbers. The point is that your average case value depends entirely on your case mix. A firm built on volume MVA has a low average fee and needs cheap, efficient acquisition. A firm chasing trucking and serious injury has a high average fee and can afford to pay far more per signed case. Same marketing budget, completely different math.

Cost per signed case is the only number that matters

Cost per lead tells you almost nothing. A channel can deliver leads at twenty dollars each and still be your most expensive source if almost none of them sign. Another can cost ten times as much per lead and be your cheapest source of actual cases.

What you want is cost per signed case (CPSC): total spend divided by signed cases, not by leads. If you are not clear on the gap between the two, start with the difference between a lead and a signed case.

The chain looks like this:

• Spend produces leads.
• A share of leads qualify.
• A share of qualified leads sign.
• Spend divided by signed cases equals CPSC.

Two firms can pay the exact same cost per lead and have CPSC numbers that differ by 3x. The difference is intake and lead quality, not the ad account.

This is why chasing cheap leads quietly destroys ROI. A pile of cheap, low-intent leads inflates your lead count, crushes your intake team, and leaves CPSC higher than if you had paid more for fewer, better-fit prospects. Volume is not the same as value.

The budget math, worked backward

Here is the whole method in four steps.

1. Estimate your average case value (the fee, not the gross settlement). 2. Decide what share of that fee you are willing to reinvest in acquisition. 3. That share is your target cost per signed case. 4. Multiply target CPSC by the number of signed cases you want per month. That is your monthly budget.

A simple example. Say your blended average fee is 12,000 dollars and you decide to reinvest 15 percent. Your target CPSC is 1,800 dollars. If you want 10 new signed cases a month, your marketing budget is roughly 18,000 dollars a month. If you want 5, it is 9,000. The budget is an output of your goals and economics, not a number you pick because it sounds reasonable.

Flip it the other way to sanity check a channel. If a source is delivering signed cases at 1,200 dollars against a 12,000 dollar average fee, that is a 10x return on spend and you should probably feed it more. If another is delivering at 6,000 dollars, that is a 2x return and worth a hard look. For a fuller view of what good looks like, see what ROI to expect from personal injury marketing.

What share of a fee is sane to reinvest

There is no universal rule, but a useful frame: most healthy PI firms reinvest somewhere in the range of 10 to 25 percent of fee into acquisition, blended across channels. Below 10 percent and you are usually underinvesting and capped on growth. Above 25 percent, the case had better be high value or you are buying revenue at a loss once you account for case costs, staff, and the cases that do not resolve.

A few honest caveats:

• That percentage is of expected fee, and not every signed case settles for the average. Build in some cushion.
• High-value, long-cycle cases (serious injury, wrongful death) justify a higher reinvestment share because the fee absorbs it.
• High-volume, low-fee cases need a low reinvestment share and ruthless efficiency, or the math never works.

If you want the broader cost picture beyond percentages, how much personal injury marketing costs lays out the real ranges.

Your case mix changes the whole budget

This is where most budgets quietly go wrong. A firm running MVA, trucking, and a few wrongful death matters cannot use one CPSC target across all of them. Blend the math and you will overpay for cheap cases and underbid on the expensive ones you most want.

Do it by segment:

• Set a separate target CPSC for each case type, based on that type’s average fee.
• Allocate spend toward the segments with the best return and the volume you can actually handle.
• Watch that your intake can keep up. A budget that doubles your serious-injury leads is wasted if those calls sit in voicemail.

This is also the case for focus. The more you concentrate on one or two case types, the sharper your economics get, which is part of why owners weigh niching down a PI practice. A tighter mix means a cleaner CPSC target and a budget you can actually defend to yourself.

Track the numbers that drive CPSC

A budget set this way only holds if you measure the inputs. At minimum, track average case value, lead-to-signed conversion, and CPSC by source. Those three tell you whether to spend more, fix intake, or cut a channel. For the full short list, see marketing KPIs PI firms should track. And if you suspect leads are signing elsewhere because of slow follow-up, the case leak calculator will show you roughly what that is costing.

The firms that win are not the ones with the lowest cost per lead. They are the ones who know what a case is worth, know their cost per signed case, and spend confidently against it. If you want a partner who builds the whole system around signed cases instead of lead counts, personal injury marketing built by Retainer Reach starts from exactly this math.
