Building a home is the best option for those looking to have the design of their dream (which is usually hard to find in the secondary house market). Moreover, it is often less expensive than buying an existing home.

This calculator provides a variety of options for you to choose from. You can customize flooring options, number of bathrooms, roofing and siding materials, type of windows, add a garage or deck, etc.

The tool also has a progressive cost per sq. ft. formula, so you can get the most accurate cost estimate. This means that when your Total square footage is LESS than 1,500, the cost / foot gradually increases to account for additional expenses incurred by the builder, with fewer "billable" square feet.

How To Use The Calculator

1) Enter the foundation size of your home (do not include garage)
2) Enter the number of bathrooms. Note that each additional bathroom requires additional plumbing and materials.
3) Choose build quality. This includes your kitchen, HVAC system, insulation, framing, and other options that you "cannot" select in the calculator.
4) Select the number of levels (floors). Note that living area as well as the amount of siding and the number of windows will proportionately increase with the number of additional floors.
5) Select your roofing and siding (exterior) materials.
6) Extra options: you can select Garage and Deck size as well as windows options.
7) Choose your location: Note that construction prices vary greatly depending on your region, and this includes both labor and materials. The difference can be between +11% for Pacific region to -5% for East South Atlantic region.

Click calculate, and you will have your personalized estimate!

Note that this estimated cost does not include the following:
- Land
- Demolition or land clearing
- Plot leveling / site work
- Architect / house plans fees
- Permits, engineering reports, and other paperwork

On average these misc costs can range between $15,000-30,000, excluding land and demo works.

How Much Does It Cost To Build A New House?

house construction costs

Homeowners across the US report spending an average of $190,000-420,000 to build a 2,000 sq.ft. house. In many middle class areas, the cost of construction for a 2,000 sq.ft. space os $295,000 This is equivalent to the price of $147.5 per square foot.

However, the average building cost per square foot can be $95 - 225, depending on a number of factors, such as:

- local labor costs
- architectural house style
- number of floors
- quality of building and finishing materials
- fees of an architect/design professional
- building permit costs
- custom vs. pre-fabricated home design

Compare The Cost Of Prefab Homes vs Original Design

Prefabricated homes prices One of the biggest factors that will lower or increase your construction costs is whether you want a custom designed house or a prefabricated one. While an original architectural house plan has the tremendous benefit of giving you exactly what you want, it also costs significantly more.

Custom homes can range in price from $150 -1,000+ per square foot, depending on the size, architectural complexity, materials, etc. Such a house will also take significantly longer to construct than a prefabricated structure.

By comparison, a prefabricated or modular home can cost at least 25-35% less than a custom one. A small prefab house under 1,500 sq.ft. without numerous customizations can be as little as $50-60,000. Average size prefabricated house (1,600-1,800 sq.ft.) costs $130,000-200,000, without major modification. It is important to keep in mind that modifications, depending on what you are looking to change or add, will drive up the initial price by as much as 30%.

These can include things like a 2-car garage, better roofing and insulation materials, high-end kitchen appliances, hardwood as opposed to engineered wood floors, better quality siding, more expensive windows, etc. Still, you will be getting a brand new home that will be cheaper than building a custom design from scratch.

    Thank you for the building calculator. Very useful. Does the calculator include the cost of a basement? If not, what kind of foundation is assumed?
    Thank you,

      The calculator assumes poured concrete foundation on level, easy to excavate land. Any obstructions / difficulties in digging and pouring the foundation should be assumed as extra cost.

      No finished basement costas are included. That’s also extra.

        Thanks for your quick reply. Assume a completely destroyed, 1920 two story vintage home with rough fieldstone, gypsum cement, basement about 26 X 42 Ft. Any estimate as to cost to remove the old basement walls and replace with poured? Obviously, the excavation work is not required. Location is Massachusetts.
        Thanks for any guidance you can give. I’m sure any estimate you make will be better than mine.

          For demo work in MA – I think you are looking at $25-35K easy. Assume there will be like 10-15 dumpsters at $500 each. Maybe less.
          Then, heavy equipment, permits, workers, etc.

          On old foundation, you only need to remove walls. You can pour new concrete over old footing. I would not build new home over old field stone – it’s asking for problems right away.

          I know these are rough numbers, but demolition and foundation work is my direct trade 🙂

          Best thing – get a few local quotes – – choose GC or New Home Construction as “project”

          PS – i’m also in MA, welcome to remodel calc 🙂

            Thanks again, Leo. No, I wouldn’t rebuild on the old fieldstone foundation. Remove it and pour new. May need new footings as well, as code has probably changed since 1914. Don’t even know if house actually has footing under fieldstone, but almost no subsidence in 100 years.
            I’m assuming that your building costs are based on the year 2015 costs. Correct?
            Am enjoying your site. Thank you.

            Yes the calculator was made in 2014 and we updated it in 2015. There weren’t many changes in costs – gas went down in price … materials pretty stable, labor also stable. Also there are many factors that we cannot account for anyway.

            PS – i’d appreciate if you share it on Facebook or twitter or google+ 😀
