Flat Fee vs Hourly Lawyer Costs: Pros, Cons, and Examples

Introduction

When hiring a lawyer in the United States, clients are often asked to choose between a flat fee and hourly billing. Understanding how these pricing models work—and when each makes sense—can help you control legal expenses and avoid unexpected costs.

What Is a Flat Fee?

A flat fee is a fixed price charged for a specific legal service, regardless of how much time the lawyer spends on the case. This model is common for predictable legal tasks where the scope of work is clearly defined.

Common flat-fee services include:

• Drafting wills and trusts
• Simple divorces
• Business formation (LLC, incorporation)
• Immigration filings
• Uncontested matters

Typical flat fees: $500 to $5,000+, depending on complexity and location.

What Is Hourly Billing?

Hourly billing charges clients based on the time a lawyer spends working on their case. Rates vary by experience, practice area, and region.

Typical hourly rates in the U.S.:

• $150–$500 per hour for most attorneys
• $600+ per hour for specialized or large-firm lawyers

Hourly billing is common for litigation, criminal defense, and cases with uncertain timelines.
