The cost of a basement is between 10 and 35 dollars per square feet. Let's say an average basement is 1,000 square feet of finished space. So the cost of a basement is between $10,000 and $35,000. 10k if you're doing most of the work yourself and up to $35,000 if you're hiring a contractor to finish your basement. Now.
The actual per square foot cost formula simply involves dividing the total cost of the home construction project by the total square feet of the project. For example, if a 400 square foot home addition costs $50,000 to build, the per square foot cost for the home addition would be $125.f on the other hand the same square foot home addition costs $75,000 to construct, because for example the inclusion of high end materials or a bathroom, the cost per square foot would be $187.50. In addition, the amount of square feet to use in the per square foot cost calculation can also be a variable.
