Tree Value Calculator
Tree Value Calculator
Enter tree’s trunk diameter measured at breast height (4.5 feet from ground) in tree value calculator. Select tree species from the dropdown menu. Rate tree’s condition (poor to excellent) based on health and structure. Input tree’s location value considering its placement and contribution to property value.
The calculator will provide both a basic worth and adjusted worth based on these factors.
- Tree Species: Oak
- DBH: 20 inches
- Height: 50 feet
- Form Factor: 0.9
- Price per BF: $3.50
Tree Volume (BF) = 0.9 × 50 × 20^2 = 18,000 BF
Tree Value = 18,000 × 3.50 = $63,000

|---|---|---|---|
| Maple (Sugar) | 10 | 1,200 | 150 |
| Oak (Red) | 15 | 2,500 | 200 |
| Pine (White) | 12 | 1,000 | 120 |

How to Calculate How Much Trees Are Worth
Measure tree’s trunk diameter in inches at breast height (DBH, 4.5 feet from ground). Calculate trunk’s cross-sectional area using the formula πr². Multiply area by base price per square inch (typically $70).
Adjust this base value using rating factors for species (0.2-1.0), condition (0.2-1.0), and location (0.4-1.0). Multiply all factors together for the final adjusted value.
- Tree Species: Walnut
- DBH: 24 inches
- Height: 60 feet
- Form Factor: 1.2
- Price per BF: $10.00
Tree Volume (BF) = 1.2 × 60 × 24^2 = 41,472 BF
Tree Value = 41,472 × 10.00 = $414,720
Tree Value Formula
The formula to estimate the worth of a tree is:
Base Value = π × (Diameter ÷ 2)² × Price per Square Inch
Adjusted Value = Base Value × Species Rating × Condition Rating × Location Rating
Where:
Price per Square Inch = $70 (industry standard)
Species Rating = 0.2 to 1.0
Condition Rating = 0.2 to 1.0
Location Rating = 0.4 to 1.0The formula requires:
- Trunk Diameter: Measured at 4.5 feet height
- Species Rating: Value based on tree type
- Condition Rating: Tree health assessment
- Location Rating: Placement value
Large Oak Example
- Diameter: 30 inches
- Species: Oak (1.0)
- Condition: Excellent (1.0)
- Location: Premium (1.0)
- Calculation: π × 15² × $70 × 1.0 × 1.0 × 1.0 = $49,480
Mature Maple Example
- Diameter: 24 inches
- Species: Maple (0.9)
- Condition: Good (0.8)
- Location: High (0.8)
- Calculation: π × 12² × $70 × 0.9 × 0.8 × 0.8 = $18,297
Young Pine Example
- Diameter: 12 inches
- Species: Pine (0.8)
- Condition: Excellent (1.0)
- Location: Medium (0.6)
- Calculation: π × 6² × $70 × 0.8 × 1.0 × 0.6 = $4,750
Damaged Birch Example
- Diameter: 18 inches
- Species: Birch (0.7)
- Condition: Poor (0.4)
- Location: Low (0.4)
- Calculation: π × 9² × $70 × 0.7 × 0.4 × 0.4 = $2,193
Historic Tree Example
- Diameter: 40 inches
- Species: Oak (1.0)
- Condition: Good (0.8)
- Location: Premium (1.0)
- Calculation: π × 20² × $70 × 1.0 × 0.8 × 1.0 = $70,372
What is Tree Value?
Tree Value is the monetary worth of a tree based on its physical characteristics, species desirability, condition, and location. This assessment considers both tangible factors like size and species, and intangible benefits including environmental contributions, aesthetic appeal, and property value enhancement.
