The Right Law Firm Marketing Budget

How Much Should Your Law Firm Spend on Marketing? A Practical Guide to Setting the Right Budget

The following post is adapted from the Law Firm CMO Playbook Podcast with Carl Downey and Matt Starosciak

“What is the right marketing budget for my law firm?” It’s one of the first questions owners ask when they start working with a fractional CMO, and it’s one of the hardest to answer. Many firms have been spending whatever felt right and doing the best they could with the information they have. What they want to know is the real number: how much they need to invest to hit their goals, regardless of what those may be.

Getting there is a process. Here’s how we approach it, the factors that can throw a budget off course, the mistakes we see most often, and some real-world ranges for different practice areas.

Start With the Right People in the Room

An effective law firm marketing budget determination starts with the right people. At a minimum, you need:

• The managing partner (or the committee or co-managing partners who make the big decisions)
• Your bookkeeper or accountant, the person who knows your true, total marketing spend and its history
• Whoever owns your intake numbers: how many leads came in and how many became signed clients
• A marketing professional, whether in-house or a fractional CMO

Bring your data to that meeting: cost per lead, cost per case, and any analytics from past months or years. Often the data exists, but no one has cut it up to find out what it actually means. Ideally, you’ll have about two years of history to analyze. That lets you see what you spent, what it produced, and what your real cost per signed case looks like

If you don’t have that data (for example, if you’re a new firm), you’ll need to make decisions based on what you can reasonably expect from a campaign, then refine as real numbers come in.

Work Backwards from Your Revenue Goal

One of the most effective ways to build a law firm marketing budget is to work backwards:

1. Set your revenue goal. What do you want to generate in the next six months, one year, and two years?
2. Subtract what comes in without paid marketing. Account for referrals and word of mouth, but don’t overestimate here.  Be realistic.
3. Divide by your average case value. That tells you how many new cases marketing needs to produce.
4. Multiply by your cost per case acquisition. That’s your marketing budget.

We used this exact approach with a Maryland estate planning firm that launched last year. The founders came from another practice and had a clear business plan with specific client and revenue targets. We knew their expected case values and their expenses, so we could calculate how many leads and signed clients marketing needed to deliver, and at what cost, to be profitable. We also deliberately budgeted higher than the math suggested, which gave the firm room to absorb the unknowns associated with a new practice.

This isn’t intuitive for most lawyers. It’s not something you learn in law school. But it’s far more effective than the alternative.

The Biggest Mistake: Treating Marketing as a Leftover

What we see often, especially with new firms, is this: cover office space, payroll, malpractice insurance, and every other expense, then use whatever is left for marketing.

That almost always produces a number that’s too low.

Marketing is a risk, but not making the right investment in business development is a bigger one. Nobody walks into your beautiful office if they can’t find you. You don’t need malpractice insurance if you don’t have clients. Marketing should never be a leftover line item. Treat it as the budget you need to perform the way you want to perform, even if that means borrowing to get started.

Set Realistic Expectations

Unrealistic expectations derail more marketing relationships than bad campaigns do. Two common versions:

Expecting outsized returns. Years ago, a young immigration lawyer told us he wanted $30,000 a month in revenue on a $1,000 monthly marketing budget. That’s a 30x return. It’s not realistic, and no honest marketer will promise it, and the most skilled ones will walk away from the opportunity.

Expecting growth without change. One firm set annual growth targets, and three months in, before any new campaigns had launched, the partners were frustrated that new client numbers were below goal. Nothing had changed except the expectation. You can’t get different results without doing something different, and more often than not that involves writing a check.

For benchmarks, consider auto accident cases. The industry standard that firms talk about is a cost per acquisition of roughly $2,000 to $3,000 per case. Not every campaign will hit that. One campaign might run at $3,700 per case while the overall average stays under $3,000, yet that more expensive campaign may still be essential to hitting your volume goals.

Build Flexibility Into Your Budget

No budget survives the year unchanged. Plan for variables like these:

• Windfall cases. Personal injury firms sometimes land a multimillion-dollar case that skews the numbers. Analyze your data both with and without those outliers. If you land one almost every year, it may be fair to count on it. But in any event, when the big case hits be sure to earmark part of it for additional marketing.
• Changes in the law. Georgia’s recent tort reform is a good example. Some firms built around negligent security cases saw that practice area collapse almost overnight and had to pivot to other, often more expensive, case types.
• Platform volatility. A suspended Google Business Profile can wipe out hundreds of reviews and a major lead source instantly. Google Local Services Ads (LSAs) are also unpredictable. One Atlanta firm went from about $25,000 a month in LSA spend to under $1,000 with essentially the same settings. Competitor bidding, missed calls, and how your intake team handles calls (Google is listening) can all affect performance. And even when LSAs are working, you can’t simply double your spend and expect double the results.
• Personnel changes. When a key partner or high-producing associate leaves, the practice area they anchored can suffer, and your marketing budget has to respond. One firm had an associate generating about half its cases. We recommended a contingency plan, and the firm said he wasn’t going anywhere. He left within three months. Have a plan before you need one.

Stop Comparing Yourself to Competitors

Measuring your budget against other firms is almost always a mistake, for two reasons.

You don’t know what they’re really spending. Some firms spend far more than anyone would guess, and others spend far less. One firm we work with has five billboards in Northwest Georgia and spends only about $2,600 a month on them. Firms don’t share their real numbers or results.

You don’t know their variables. Intake processes, case thresholds, and which cases a firm accepts or turns away all shape performance.

The opposite trap is just as dangerous: “We can’t compete with the giant national firm, so why bother?” You do have to compete, just not with their playbook. Work within what your firm can do.

Ballpark Budgets by Practice Area

Every firm is different, so treat these as starting points rather than rules. They’re ranges we’ve seen work in practice:

• Estate planning (countywide, near a major metro): $15,000–$20,000/month. Once established, this can support $500,000 to $1 million or more in revenue. That’s roughly the fee from three or four estate plans a month, and it can produce 10 to 15 new matters monthly.
• Criminal defense / DUI (multi-county, mostly digital): $10,000–$15,000/month for a solo practitioner, and closer to $20,000–$30,000/month for a firm with three or four lawyers.
• Consumer bankruptcy: We’ve typically seen $300–$500 per signed case. Compare that with your average fee, blended across Chapter 7s and 13s, to calculate your budget.
• Personal injury (regional, around five lawyers): Budget as a percentage of revenue. 25% is a solid starting point. On $2 million in revenue, that’s about $500,000 a year. Aggressive growth plans may call for 30–40%.
• Family law / divorce: $10,000–$20,000/month for firms with $1–2 million in revenue. Firms targeting high-value contested cases, which can generate $20,000–$40,000 per client over a year, may spend more.

Start Planning Now

The best time to set next year’s budget is in Q4. Around October 1, review what performed this year and in previous years, analyze your cost per case by channel, and decide what you’ll invest in the year ahead.

The right marketing budget isn’t a guess, and it isn’t a leftover. It’s a number you calculate from your goals, your data, and a realistic view of what marketing can deliver.
