How Much Does a Personal Injury Marketing Agency Cost?

A personal injury marketing agency typically costs a few thousand dollars a month on the low end to five figures for a full-service program — plus your ad budget, which is usually separate. But the headline number matters less than the pricing model, because the model decides whose interests the agency is actually serving. Here’s how it breaks down.

The pricing models

• Flat monthly retainer. A fixed fee for an agreed scope (often the full stack — LSAs, paid search, SEO, reviews). Predictable, and it aligns the agency around building a system rather than billing by volume. Commonly a few thousand to low five figures per month depending on scope and market.
• Percentage of ad spend. The agency takes 10–20% of what you spend on ads. Simple, but it rewards spending more, not signing more — the incentive points the wrong way.
• Pay-per-lead. You pay per lead delivered. Feels safe, but it rewards volume over quality, and leads are often shared. (See flat-fee vs. pay-per-lead.)
• Pay-per-case / performance. You pay per signed case. Highest alignment on paper, but verify exclusivity and cancellation terms — a "signed" case that walks isn’t one you should pay full price for.

Retainer vs. ad budget — don’t confuse them

A common surprise: the agency fee and the ad spend are usually two separate numbers. A $4,000/month retainer might sit on top of a $10,000/month Google Ads budget. When you compare agencies, compare like for like — total cost *and* what’s included — or you’ll think one is cheaper when it just unbundled the line items.

What drives the price

• Scope — one channel vs. the full engine.
• Market — competitive metros cost more to compete in.
• Case types — truck and wrongful death campaigns cost more to run than soft-tissue MVA.
• Whether intake is included — managed intake adds cost but usually pays for itself in signed cases.

The number that actually matters

Not the retainer. Cost per signed case. A $3,000/month agency that signs you two extra serious cases is far cheaper than a $1,500/month one that signs none. Judge agencies on the cases they produce relative to total spend, not on the sticker fee. (For the broader picture, see how much PI marketing costs.)

The takeaway

Expect a few thousand a month to five figures for a full program, plus a separate ad budget — but weight the model over the number. Flat-fee aligns the agency with signed cases and lets you own the assets; percentage-of-spend and pure pay-per-lead often misalign incentives. Then judge everything on cost per signed case, because that’s the only price that touches your bottom line. If you want a flat-fee, signed-case-aligned program run exclusively in your market, that’s how we’re built.
