Tree Value Calculator
Trees add real monetary value to a property, and knowing that value matters for insurance claims, property appraisals, and legal disputes. This calculator uses the trunk formula method, the most widely accepted approach in the arboriculture industry, to estimate what a tree is worth.
The trunk formula method, published by the Council of Tree and Landscape Appraisers (CTLA), calculates tree value in three steps. First, it determines the cross-sectional area of the trunk at breast height (4.5 feet above ground). Second, it multiplies that area by a regional cost per square inch based on the replacement cost of a similar nursery tree. Third, it adjusts the result by species, condition, and location ratings.
Species rating reflects how desirable the tree is in your region. A healthy red oak in the Midwest might rate 90%, while a fast-growing, weak-wooded silver maple might rate 40%. Condition rating accounts for health, structural defects, and canopy density. Location rating considers whether the tree is well-placed on the property, visible, and not in conflict with structures or utilities.
The cost per square inch varies by region. In 2024, values typically range from $50 to $100 per square inch in most U.S. cities. Your local ISA-certified arborist or the regional CTLA guide can provide the current number for your area. A large, healthy, well-placed tree can easily appraise at $10,000 to $50,000 or more.
