To figure out how much the wood flooring will cost, calculate the square footage of the room, then add 5 to 10 percent for cuts and waste. Take that figure and multiply it by the square foot price of the flooring to find the cost. Don’t forget to add on the price of extras such as nails, moldings, and thresholds.

How Much Does It Cost to Install 500 Square Feet of Hardwood Floors? Based on the national average cost per square foot, expect to pay between $2,500 and $5,000 for a 500-square-foot solid wood floor. For engineered wood, plan on forking over roughly $2,000 to $4,500 for installation costs for the same size room.

Typical room sizes and standardized wood flooring make doing the math straightforward, while custom homes and randomly sized wood involves more complex calculations. Measure the area to be covered by the flooring in feet. Multiply length times width to get the square footage of your area.

Square off each section of the area you are going to install hardwood flooring so you can measure the width and length to calculate the square footages.

How it is Calculated. The flooring cost formula used by the calculator is simple: the cost per square foot of material is multiplied by the number of square feet in need of flooring. Simply enter these factors, and the calculator will provide you with the total flooring cost for your project.

While the average floor installation cost will mostly depend on the type of floor you’re adding, based on 17,000 recent flooring projects, the average cost to install a new floor is approximately $2,300.
