Tree value can mean timber value, replacement cost, ecosystem value, amenity value, or a formal appraisal—and those are not interchangeable. The Tree Value Calculator uses a specific simplified index based on tree type, circumference, and height, so it is best for a quick standardized estimate rather than an insurance, legal, or professional appraisal.

What this calculator does

Choose one of the available tree types, then enter trunk circumference and tree height. Each tree type has a built-in basic-value factor. The calculator converts circumference to inches and height to feet, multiplies those measurements by the selected factor, and returns an estimated value in U.S. dollars. The result card also shows the factor and normalized dimensions used.

How to use it

Measure circumference using the same trunk-measurement convention you would use for forestry inventory, and enter total tree height rather than merchantable log length. Select the tree type that actually matches the specimen. If identification is uncertain, resolve that first because the basic-value factor can change the estimate substantially. Use the unit controls instead of manually mixing metric and U.S. customary values.

How the calculation works

The model follows: tree value = circumference in inches × height in feet × tree-type basic value. The relationship is linear, so doubling circumference or height doubles the estimate when the other inputs and tree type stay unchanged. The species factor is also a direct multiplier and is the reason two trees with identical dimensions can receive different estimates in this model.

Example

Using the defaults—maple, 17 in circumference, and 16 ft height—the basic value factor is 2.44. The calculator returns 17 × 16 × 2.44 = $663.68 as the estimated tree value. The result card also shows the selected tree type, basic value, circumference, and height so the estimate can be reproduced.

How to interpret the result

Interpret the number only within this calculator’s valuation method. It can be useful for educational comparisons and rough screening, but it does not represent a guaranteed sale price or replacement award. A formal tree appraisal may consider species condition, trunk area, location, functional limitations, depreciation, regional costs, timber grade, defects, accessibility, and the purpose of the appraisal.

Limitations and notes

Market and appraisal standards vary by location and use case, and a simple circumference × height × factor model cannot capture tree health, structural risk, landscape contribution, timber quality, ownership issues, or removal costs. For insurance claims, litigation, development impacts, or high-value trees, use a qualified arborist or appraiser and the standard required in your jurisdiction.
