How to Use This Calculator
  1. Enter Trunk Diameter (DBH), Species Rating (1-5), and Condition Rating (1-5).
  2. Set Location Rating (1-5) and Replacement Cost per Sq In.
  3. Review the Appraised Value ($) result.
  4. Use Trunk Cross-Section Area (sq in) and Basic Value ($) to inform your decision.
  5. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

What each input means

Trunk Diameter (DBH)
Diameter at breast height (4.5 ft above ground) in inches.
Species Rating (1-5)
Species desirability: 1=Invasive/weak, 5=Premium native or specimen.
Condition Rating (1-5)
Overall health: 1=Dying, 3=Fair, 5=Excellent.
Location Rating (1-5)
Site contribution: 1=Poor placement, 5=Focal specimen in prime location.
Replacement Cost per Sq In
Regional cost to plant a 1 sq in caliper tree. Typically $50-$100.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Trunk Diameter (DBH) = 18, Species Rating (1-5) = 4, Condition Rating (1-5) = 4, Location Rating (1-5) = 3 = 5 input(s) provided
  2. Calculate Appraised Value
    Appraised Value
    7328.74 = $7,328.74
  3. Calculate Trunk Cross-Section Area
    Trunk Cross-Section Area
    254.47 = 254.47
  4. Calculate Basic Value
    Basic Value
    19085.25 = $19,085.25
