What firms spend: in the one recent law-specific survey with a primary source, most Canadian firms put 1% to 5% of revenue into marketing and a third put in less than 1%, against a cross-industry 9.0%. What they should spend is a different question, answered by working back from the matters the firm wants and checking against those figures and the rules.
This guide is part of our professional services series. The general method is in how much to spend on marketing; what the website costs is in law firm website design; the ideas the budget buys are in attorney marketing ideas.
What law firms spend: the Canadian survey
bestlawfirms.com surveyed 344 Canadian firms, from solo practices to national firms employing nearly 15,000 lawyers, for its 2026 Legal Market Report and reported the results on 2 January 2026: 55% of firms spend 1% to 5% of annual revenue on marketing, one-third spend less than 1%, and just one in ten allocate 6% to 10%. More than two-thirds of large and midsize firms sit in the 1% to 5% band; less than half of small firms do. The same survey found that only 41% of firms have the systems and technology to measure the return on their marketing: 78% of large firms, 50% of midsize and 34% of small. We found no US law-specific spending survey with an opened primary source, so none is quoted; figures you see elsewhere are mostly agency recommendations.
The cross-industry benchmark
The CMO Survey's 2026 Highlights and Insights report (35th edition; fielded 7 to 29 January 2026; 308 marketing leaders at for-profit US companies) puts marketing budgets at 9.0% of company revenues and 9.6% of overall budgets. Law firms, on the Canadian evidence, spend a fraction of that, which is partly the profession's reliance on referrals and partly habit. A firm that wants to grow from search and content rather than from the partners' networks will usually need to spend more than its peers and less than the cross-industry average, and to measure it, which most do not.
Why the percentage is the wrong starting point
A percentage of revenue tells you what others spend, not what your goal costs. A firm that wants twenty more family-law matters next year needs a known number of consultations, which needs a known number of inquiries, each of which costs a knowable amount by channel. That arithmetic gives the budget; the percentages above tell you whether it is sensible. Firms that start from the percentage spend it; firms that start from the matters can stop spending when the matters arrive.
Working the number back from matters
Six lines, in order:
- Matters wanted, by practice area, with the average fee per matter.
- Consultations per matter: how many consultations the firm holds to sign one client, from last year's intake records.
- Inquiries per consultation: how many calls and forms produce one consultation.
- Cost per inquiry by channel, from your own data where you have it, or from a planned test where you do not.
- The non-media lines: the website and its upkeep, the profile and reviews work, the intake system, the content, the review and filing time the rules require.
- Held back: 10 to 15% for what the first quarter teaches.
What the channels and agencies cost: public figures
Paid search in law is the dearest in the market. ppc.land's report on WordStream's 2026 Google Ads benchmarks (29 June 2026; 13,474 US campaigns, April 2025 to March 2026) gives cross-industry medians of $5.42 per click and $66.69 per lead, and names legal services the highest-cost category at $9.87 per click; competitive practice areas in large cities price well above that. Our guide to how much Google Ads costs covers the mechanics.
For agency help, Clutch's Digital Marketing Agency Pricing Guide 2026 (updated 21 September 2026, from 106,043 companies' pricing data) puts monthly engagements at $5,000 to $50,000 a month, most agencies at $25 to $49 an hour, and SEO, PPC, content, email and social media marketing each in a $100 to $149 hourly band. Local search work, the channel most firms should fund first, is covered by our local SEO service and quoted against scope; we publish no rate card.
The bar rules as a budget line
Every piece a law firm publishes is governed by its state bar's rules, based on the ABA Model Rules 7.1 to 7.3, and in Canada by the provincial law society's marketing rules. Texas's Rule 7.01 is a clear example of the US standard: no false or misleading communication about a lawyer's services, where misleading includes a material misrepresentation, an omission that makes the whole misleading, a statement substantially likely to create unjustified expectations about results, and an unsubstantiated comparison with other lawyers; a lawyer may claim credit for a prior result only with a substantial role, and an advertised verdict later reduced must be shown with the amount received. Texas's Rule 7.04 adds a filing requirement: advertisements go to the State Bar's Advertising Review Committee no later than ten days after dissemination, with a fee. Ontario's Law Society Rule 4.2-1 allows a lawyer to market legal services only if the marketing is demonstrably true, accurate and verifiable, neither misleading, confusing nor deceptive, and in the best interests of the public and consistent with a high standard of professionalism; its commentary says a statement of money recovered or past success needs a further statement that past results are not necessarily indicative of future results, and treats awards and rankings built on superlative titles as marketing that must meet the same test. Budget the partner's review time for every piece and the filing fees where they apply, and spend nothing on claims the rules forbid, including promised outcomes. This is a summary, not legal advice.
Where the money goes in a law firm budget
The table below sets out the usual lines for a small or midsize firm and how they shift by growth goal. Two points stand out from the Canadian survey: the measurement line (intake tracking, call recording with consent, source on every inquiry) is the one most firms skip, and it is the one that lets the budget be judged; and the local search line (the Business Profile, reviews and office pages) is the cheapest source of inquiries for most firms and the one paid search should follow, not replace.
A worked example
A made-up firm, not a client: a six-lawyer family and estates firm in a mid-sized US city wants twenty more family-law matters next year at its average fee. Intake records show one in three consultations signs, and one in four inquiries books a consultation, so the firm needs sixty consultations and about 240 inquiries. Last year's data put the cost per inquiry from local search at a low figure once the profile and reviews were in order, and from paid search at several times that, in line with the legal category's high cost per click. The budget takes the local search work first, a paid search campaign sized to fill the gap, the intake tracking that makes both measurable, the partner's review and the state's filing fees, and 12% held back. The total lands between the Canadian peers' 1% to 5% band and the cross-industry 9.0%, and the firm can say why.
Common law firm budget mistakes
The faults we see most:
- Starting from a percentage. It is a check on a number worked back from matters, not the number.
- Paid search before local search. The dearest channel funded before the cheapest.
- No measurement line. Six in ten Canadian firms cannot tell whether marketing worked; the tracking costs less than one wasted month of media.
- Spending on forbidden claims. Promised outcomes, unsubstantiated comparisons and results without a substantial role cost twice: the spend and the complaint.
- No review or filing time. Where the bar requires filing, it is part of every campaign's cost.
- No held-back share. The first quarter changes the plan.
Conclusion
A law firm marketing budget is worked back from the matters the firm wants, through consultations and inquiries to a cost by channel, then checked against what peers spend (most Canadian firms 1% to 5% of revenue, a third under 1%) and what industry spends (9.0% across US companies), and shaped by the bar's rules. The measurement line is the one that decides whether next year's budget is a plan or a guess.
