Enter the total cost of the drywall and the total wall area into the calculator to determine the drywall cost per square foot.

Drywall Cost Per Square Foot Formula

The following equation is used to calculate the Drywall Cost Per Square Foot.

  • Where DCSF is the drywall cost per square foot ($/ft)
  • TCD is the total cost of drywall ($)
  • TAD is the total area of drywall (ft^2)

To calculate the drywall cost per square foot, divide the total cost of drywall by the total area of drywall.

What is the average Drywall Cost Per Square Foot?

The average cost of drywall per square foot depends on where you are located in the country, as well as the type of drywall that you choose. Drywall comes in a range of thicknesses from 1/4 inch to one and a half inches. The higher the thickness, the more expensive it becomes.

Gypsum board is what you typically find in residential construction; it’s lightweight and easy to install. Fiberglass is heavier but more durable and can save you money over time because it can be reused. It’s also better for mold prevention and has a higher R-value (resistance to heat).

You can expect to pay between $1.30 and $2.40 per square foot if you purchase your own drywall.

The average cost is closer to $1.50 when you rent the equipment to do it yourself.

If you hire a professional to replace your drywall for you, then your costs are likely closer to $3.00 per square foot when everything is said and done.
