Market Size for Estate planning lawyers in 2026 [Example]

The total available market (TAM) for estate planning lawyers globally can be estimated by looking at the population of individuals aged 30 and above, who are more likely to engage in estate planning services. With approximately 2 billion people in this age group worldwide, and estimating that around 0.4% might seek estate planning annually, this translates to about 8 million potential clients. With an average legal fee of $5,000 for estate planning services, the TAM grows to approximately $40 billion annually.

This market includes not only the affluent who are traditionally targeted by estate planning lawyers but also the broader middle-class demographic, which has become increasingly aware of the importance of estate planning in recent years. This broad reach is significant due to emerging trends in financial literacy and the growing aging population globally.

The serviceable addressable market (SAM) is the portion of TAM that a solopreneur estate planning lawyer can realistically reach, considering factors such as competition, geographical restrictions, and marketing capabilities. Targeting a more specific audience—such as middle to upper-middle-class families and individuals who actively seek estate planning guidance—could narrow our outreach effectively.

Assuming that about 20% of the TAM is realistically reachable, this brings our potential clients down to approximately 1.6 million. Multiplying this by the average service fee of $5,000 results in an annual SAM of around $8 billion, representing a highly attainable and targeted segment of the broader estate planning market.

The serviceable obtainable market (SOM) reflects what a new solo estate planning lawyer might hope to capture in their first year of business. Considering the competitive nature of the industry and the time it takes to establish oneself, a conservative estimate suggests capturing around 2% of the SAM.

This would mean approximating 32,000 clients in the first year. When multiplied by an average fee of $5,000 per estate plan, the first-year revenue comes to about $160 million. This represents a realistic goal for a solopreneur looking to establish themselves within the estate planning market without unrealistic expectations.
