Enter the siding area, siding cost per square foot, length of trim needed, and cost of trim per foot into the calculator to determine the siding estimate.

Siding Estimate Formula

The following formula is used to calculate the siding estimate.

SE = (SA * SC) + (L * LC)

Variables:

  • SE is the siding estimate ($)
  • SA is the siding area (square feet)
  • SC is the siding cost per square foot ($)
  • L is the length of trim needed (feet)
  • LC is the cost of trim per foot ($)

To calculate the siding estimate, multiply the siding area by the siding cost per square foot. Then, multiply the length of trim needed by the cost of trim per foot. Add these two results together to get the total siding estimate.

What is a Siding Estimate?

A siding estimate is a calculated approximation of the cost involved in installing or replacing the siding on a building. This estimate typically includes the cost of materials, labor, and any additional services such as old siding removal or disposal. It is usually provided by a contractor or a siding company after assessing the size, design, and condition of the building, as well as the type and quality of siding material chosen by the homeowner.

How to Calculate Siding Estimate?

The following steps outline how to calculate a Siding Estimate using the given formula:


  1. First, determine the siding area (SA) in square feet.
  2. Next, determine the siding cost per square foot (SC) in dollars.
  3. Next, determine the length of trim needed (L) in feet.
  4. Next, determine the cost of trim per foot (LC) in dollars.
  5. Use the formula SE = (SA * SC) + (L * LC) to calculate the Siding Estimate.
  6. After inserting the values of SA, SC, L, and LC into the formula, calculate the result.

Example Problem:

Use the following variables as an example problem to test your knowledge:

siding area (SA) = 500 square feet

siding cost per square foot (SC) = $2.50

length of trim needed (L) = 50 feet

cost of trim per foot (LC) = $1.75
