Planning a siding project can feel overwhelming without knowing how much it will cost. Whether you’re a homeowner upgrading your exterior or a contractor preparing a quote, estimating siding material and installation costs is crucial.

Our Siding Estimate Calculator makes this process simple. By entering your wall dimensions, cost per square foot of siding, and installation cost, you can instantly get a clear cost estimate for your siding project.

Formula for Siding Estimate

Step 1: Calculate Wall Area

$\text{Wall Area} = \text{Wall Height} \times \text{Wall Width}$

Step 2: Multiply by Number of Walls

$\text{Total Siding Square Footage} = \text{Wall Area} \times \text{Number of Walls}$

Step 3: Material Cost

$\text{Estimated Material Cost} = \text{Total Siding Square Footage} \times \text{Cost per sq.ft of Siding}$

Step 4: Installation Cost

$\text{Estimated Installation Cost} = \text{Total Siding Square Footage} \times \text{Installation Cost per sq.ft}$

Step 5: Total Estimated Project Cost

$\text{Total Estimated Project Cost} = \text{Estimated Material Cost} + \text{Estimated Installation Cost}$

Example Calculation

Suppose you have the following details:

Wall Height = 10 ft
Wall Width = 30 ft
Number of Walls = 2
Cost per sq.ft of Siding = $6
Installation Cost per sq.ft = $4

Step 1:

$\text{Wall Area} = 10 \times 30 = 300 \, \text{ft}^2$

Step 2:

$\text{Total Siding Square Footage} = 300 \times 2 = 600 \, \text{ft}^2$

Step 3:

$\text{Estimated Material Cost} = 600 \times 6 = 3600 \, \text{USD}$

Step 4:

$\text{Estimated Installation Cost} = 600 \times 4 = 2400 \, \text{USD}$

Step 5:

$\text{Total Estimated Project Cost} = 3600 + 2400 = 6000 \, \text{USD}$
