This calculator provides two ways to look at your monthly marketing budget. First, it calculates a budget based on your `Gross Annual Revenue` and your `Target Marketing % of Revenue`. For example, $1,000,000 annual revenue at 2% means a $20,000 annual, or $1,667 monthly budget. Second, and more importantly for growth-focused firms, it calculates the budget needed to acquire your `Desired New Clients per Month` while maintaining your `Target LTV:CAC Ratio`.
A small personal injury law firm (2 attorneys) wants to grow quickly, aiming for 5 new cases per month.
$8,333 per month
With an average case value of $5,000 and a target LTV:CAC ratio of 3:1, the firm can afford to spend $1,667 to acquire each client ($5,000 / 3). To get 5 new clients monthly, they need a budget of $1,667 * 5 = $8,335. This is a higher percentage of revenue, typical for small, growing firms.
A mid-size corporate law firm with $3,000,000 annual revenue seeks consistent growth, targeting 10 new clients monthly.
$25,000 per month
This firm has a higher average case value of $10,000. With a healthy 4:1 LTV:CAC ratio, their allowable Customer Acquisition Cost is $2,500 per client ($10,000 / 4). To acquire 10 new clients each month, they need to budget $2,500 * 10 = $25,000.
A solo attorney is launching a new niche practice with lower initial case values but high volume potential, aiming for 15 new clients.
$15,000 per month
For a new practice with an average case value of $3,000 and a slightly more aggressive 2:1 LTV:CAC ratio, the allowable CAC is $1,500 per client ($3,000 / 2). To bring in 10 new clients per month, a budget of $1,500 * 10 = $15,000 is needed.

See your real numbersThis calculator uses industry benchmarks and common marketing formulas. Law firms spend around 2% of gross revenue on marketing, with small firms often spending 7-10%. The core calculation for desired client acquisition is based on your Average Case Value (ACV), your target Lifetime Value to
Law firms generally allocate around 2% of their gross revenue to marketing. However, this varies significantly. Small firms (1-10 attorneys) often spend 7-10% of their revenue, especially newer ones. Some firms can go as high as 20% depending on their growth goals and competitive landscape. The key is to align your budget with your specific growth targets, not just an arbitrary percentage.
Effective allocation is critical. Based on recent trends, about 45% of a law firm's digital marketing budget goes to SEO, 30% to PPC (paid ads), 10% to social media, and 15% to traditional marketing. However, for 40% of firms, online marketing accounts for 76-100% of their total budget. It's not about picking one channel, but understanding how SEO compounds and paid ads deliver immediate pipeline when combined strategically.
Digital ad spending for legal services has seen a significant increase, up 84% in recent years, even as the quantity of ads decreased by over 50%. Overall legal ads are up 39%. This trend reflects a shift towards more targeted and efficient online advertising to reach specific client demographics. Firms are recognizing the immediate impact paid ads can have on client acquisition, especially when paired with a strong SEO foundation.
Tracking ROI requires clear metrics. You need to know your Average Case Value (ACV) and your Customer Acquisition Cost (CAC). The calculator uses a target LTV:CAC ratio to help you project a budget that delivers a strong return. While 78% of firms use paid search, 82% report underwhelming ROI, often due to poor tracking and strategy. Implementing conversion tracking and clear reporting is essential for measuring actual results.
You don't have to choose. Smart law firms combine both. SEO builds long-term authority, organic visibility, and compounds over time. Paid ads, like Google Ads, provide immediate lead generation and can fill your pipeline right away. A combined strategy ensures you capture both immediate demand and build sustainable growth, giving you the best of both worlds. This approach beats an either/or mindset.
When increasing your budget, consider your firm's growth goals, current revenue, and desired new client volume. Over 69% of smaller firms and 79% of larger firms plan to increase their marketing budgets. Focus on areas like website optimization (66% of firms), social media (60%), and paid ads (48%). Ensure your increases are tied to measurable outcomes and a clear strategy, not just spending more for the sake of it.
