How to calculate the cost per square foot for flooring

As cost conscious consumers, many of us try our best to find the best deal on flooring by comparing the best carpet prices from different websites or visiting a flooring store in person. Of the many things to keep in mind while trying to find the best price per square foot for flooring is waste factor. Size and prices are variable due to changing waste factors and the only way to get an accurate price per square foot is to include these variables.

A basic rule of thumb when calculating flooring waste is

  • 10% for hardwood, luxury vinyl plank, or laminate flooring
    In some cases, such as diagonal installs, the waste factor may be as much as 15%
  • 25% for sheet vinyl flooring
    Fluctuations are based on size, seam layout, and pattern repeat. It is not uncommon for a vinyl waste factor to be as much as 35-40% in some cases especially in kitchens and rooms larger than 12 feet in width.
  • 13%-20% for carpeting
    In some situations where you may have a small room or a large repeated pattern, the waste factor can be much larger. Also do not forget about the carpet padding and tack strips.
