Granite Cost Calculator


Granite countertops are a popular choice for kitchens and bathrooms due to their durability and aesthetic appeal. If you're considering installing granite countertops in your home, it's essential to budget for the cost. The Granite Cost Calculator helps you estimate the total cost based on the dimensions of your countertop and the price per square foot.


To estimate the cost of granite countertops, we use the following formula:

  • Area (in square feet) = (Length × Width × Thickness) / 12 (to convert thickness from inches to feet)
  • Total Cost = Area × Price per Square Foot ($)

How to Use

Using the Granite Cost Calculator is easy:

  1. Enter the length of the countertop in feet.
  2. Input the width of the countertop in feet.
  3. Specify the thickness of the granite in inches.
  4. Enter the price per square foot of the granite.
  5. Click the "Calculate" button.

The calculator will provide you with an estimated cost for your granite countertop.


Let's say you want to install a granite countertop that is 10 feet long, 2.5 feet wide, and 1.25 inches thick. The price per square foot of granite is $60. The calculator would determine the estimated cost as follows:

  • Area = (10 feet × 2.5 feet × 1.25 inches) / 12 = 2.08 square feet
  • Total Cost = 2.08 square feet × $60/sqft = $124.80
