Why These Metrics Matter

In a competitive legal market, understanding what you’re missing—and what you’re actually earning—can define your contingency fee law firm’s growth trajectory. The stakes are high, and the margin between success and stagnation is thin. Firms must navigate the challenges of capturing new cases, managing marketing efforts, and delivering exceptional client experiences.

That’s why Peter Webb emphasizes two critical business levers for growth: opportunity cost and marketing ROI. By recognizing and measuring these metrics, firms can make more strategic decisions, avoid missed opportunities, and drive long-term profitability.

Opportunity Cost: What Are You Leaving on the Table?

Opportunity cost reflects what a firm loses by not acting on an available opportunity. As Peter explains, “Opportunity cost is a business term…what is it costing you to not execute the opportunity to get that new potential case.”

For contingency fee law firms, the cost of inaction can be steep. Failing to answer phone calls or ignoring market opportunities can result in lost cases, lost revenue, and ultimately, lost competitive ground.

Peter illustrates this with a compelling example: “If you get 10 phone calls and you only answer five of them and one in every five people becomes a client… those five calls you didn’t take, you just lost a case. And if your average case fee is $100,000, it costs you $100,000 to not get that. Now that’s one part of opportunity cost.”

The takeaway? Inaction and missed market opportunities can lead to irrelevance—just like Blockbuster losing out to Netflix (as Peter notes).

Marketing ROI: Are You Spending Smarter?

Marketing ROI (return on investment) measures the return on your firm’s marketing spend. “Essentially marketing ROI is the dollars you’re putting into marketing,” says Peter.

Many law firms overlook this metric, failing to assess whether their marketing efforts are delivering actual returns or merely breaking even. Peter challenges firms to ask: “Are you getting the return on investment to make it worth your while?”

If the answer is no, it’s time to rethink your approach. Evaluating marketing strategies to ensure they provide a positive ROI is essential for sustainable growth.

Running Your Contingency Fee Law Firm as a Business

The core message from Peter Webb is clear: to grow, contingency fee firms must think and operate like performance-driven businesses.

That means:

• Measuring and managing opportunity cost
• Maximizing marketing ROI
• Delivering an excellent client experience at every stage

By doing so, law firms can avoid the pitfall of merely breaking even—which as Peter notes, might be equivalent to not taking on cases at all:

“Sometimes I talked to firms and they’re breaking even, and I say, did you know it’d be better for you to just not even take any of these cases and take a vacation and not do all of this because you’re not providing an excellent experience, clearly, because it hasn’t been thought out from the inception through to the completion of the case”.
