What is the Calculation Ladder?
  • The Calculation Ladder is also known as the “Calc Ladder” or the “Adjustment Value Grid”  is a table that breaks down how different key attributes and their adjustments impact the value of a property. The calc ladder has 4 columns with the following headings: 
    • Property Characteristics: A description of the property attribute (i.e., Property Size, Acreage, Year built, Basement, Number of Bedrooms, etc.
    • Adjustment: The rate, or factor, that will be applied to the characteristic
    • Base Rate: A number, which is the starting value, in terms of the property characteristic’s units (per Sqft in this case), that will be multiplied by the adjustment factor
    • Value: Shows the value as calculated by multiplying the previous value by the adjustment for the property characteristic
