Determine the Cost of Materials for a Job
A cost per square foot calculation will help you clearly understand the exact amount of materials you will need to get a job done. Suppose, for example, you need to paint a room. You could guess at the amount of paint needed, thereby guessing at the overall cost of paint required, and then tack on a profit margin and bill your customer. However, this can be problematic. If you need more paint than you anticipated, you face the uncomfortable situation of either redrafting the bill, or swallowing up your own profit with extra materials.
With a Cost Per Square Foot Calculator, you simply fill in the following:
  1. Width
  2. Height
  3. Total Cost

Do not enter inches into the online calculator. Be sure to convert to feet. For example, 10ft 3in = 10.25 ft.
Enter the width and height dimensions in feet for your job, as well as your guess at what the materials will cost you. The calculator will tell you the exact cost per square foot, given the cost you’d like to spend. With this handy tool, it is easy to see if you are overestimating or underestimating your material costs. After seeing your results, you can adjust your cost estimate accordingly.
