Key takeaways
- Vendor-published Google Ads figures put the average personal injury cost per lead between about $312 and $512 by case type.
- Regional averages in the same source range from $314 (Midwest) to $468 (Northeast), with the Southeast at $382.
- Cost per signed case is the number that matters. Published figures for it are thin and mostly unsourced.
- Use these as ranges, then calculate your own.
How much does a personal injury lead cost?
Marketing vendors publish cost-per-lead figures, and they vary. One widely cited set, published by Webtonic and attributed to a 2025 Taqtics analysis of 49 personal injury firms with $21.4 million in tracked spend, gives Google Ads averages by case type:
| Case type | Average cost per lead | Range given |
|---|---|---|
| Slip and fall | $312 | $200 to $500 |
| Workplace injury | $354 | $250 to $550 |
| Auto accident | $391 | $300 to $600 |
| Product liability | $476 | $350 to $700 |
| Medical malpractice | $512 | $400 to $800+ |
The same article gives regional averages, attributed to Taqtics and Lexgro: Midwest $314, Southeast $382, West $401, Northeast $468. LawRuler gives a broader $150 to $500 range for personal injury leads, with no source. These are vendor figures, and they cover Google Ads, not every channel.
What is cost per signed case, and why does it matter more?
A cheap lead that rarely signs costs more per case than a pricier one that does. Cost per signed case is total marketing spend divided by cases signed in the same period.
Published cost-per-signed-case figures are thin. Webtonic lists $1,500 to $5,000+ for Google Ads, without naming a sample, and a local service ads figure of about $960 that it calculates from $240 per lead at a roughly 25% lead-to-case rate. LawRuler’s article gives only a hypothetical example.
How do you work out your own cost per signed case?
LawRuler’s hypothetical example shows the arithmetic. It is an illustration, not a benchmark: a firm spends $10,000 on one Google Ads campaign and gets 40 leads. Of those, 30 are contacted, 15 book a consultation, 10 attend, and 4 sign.
| Step | Count | Share of leads |
|---|---|---|
| Leads | 40 | 100% |
| Contacted | 30 | 75% |
| Consultations booked | 15 | 38% |
| Consultations completed | 10 | 25% |
| Signed | 4 | 10% |
$10,000 divided by 4 signed cases is $2,500 per signed case. Track the same funnel for your firm for a few months, by channel, and you have your own numbers.
Why is the first step in that funnel so important?
The “contacted” step is where speed matters. Studies of law firm response times show most firms are slower than five minutes (see our speed-to-lead guide). If a faster first call lifts the share of leads reached, the same ad spend produces more consultations. Use the missed-lead calculator with your own numbers.
Why do the figures disagree?
- Definitions. Some count media spend only; others include agency fees and staff time.
- Samples. Studies cover different firms, markets and years.
- Interest. Most come from marketing vendors, whose figures may favor their own channel.
