Cost to Build a House
Calculator
Enter the size, pick a finish level and location, and see what building your home costs — stage by stage.
A new home's price is mostly decided before anyone pours concrete: by its size, its finish level, and the ground it sits on. The calculator below turns those choices into a stage-by-stage budget using how builders actually spend money on a new house. Under it you'll find what we learned running every combination, how construction loans work, and the decisions that trip up first-time builders.
Key takeaways
- What does it cost to build a house? About $564,500 for a 2,400 sq ft one-story home with midrange finishes and a two-car garage in an average-cost area — roughly $235 per sq ft, before land.
- What drives the price most? Finish level and location. Custom work adds about 40%, and a very high-cost metro adds about 45%.
- Where does the money go? Interior finishes and the plumbing, electrical and HVAC systems take over 40% of construction cost.
- Is a smaller house really cheaper? Yes, though not per square foot. Cutting from 2,400 to 1,800 sq ft saved about $117,500 in our testing, even as the per-foot price rose.
- Does a basement pay off? It added about $100,000 to our typical home; a slab is the cheapest foundation by far.
- How long does it take? Plan on seven to eleven months after permits for a typical home, longer for custom builds.
- Are lumber prices higher? Canadian softwood, the bulk of U.S. lumber imports, now carries about 35% in duties plus a 10% tariff.
- How do people pay for it? Usually with a construction-to-permanent loan, which funds the build in stages and becomes your mortgage at move-in.

What we found running every combination
In our testing we ran 25,920 combinations — every finish level, story count, foundation, garage, lot type, location and reserve, across ten home sizes from 1,000 to 5,000 sq ft. Before land, they ranged from $150,500 for a small builder-grade home in a lower-cost area to about $3.8 million for a 5,000 sq ft luxury home on a rural lot in a very high-cost metro. Here is what one change did to the typical $564,500 home: 2,400 sq ft, one story, midrange, slab, two-car garage, a lot with city utilities, average-cost area.
Each bar changes one setting from the default and excludes land.
We found that the two biggest savings were deciding to build smaller and choosing builder-grade finishes — each worth more than $110,000 on the typical home. Going to two stories saved less than many people expect, under 5%, because stairs and a second set of walls eat into the savings from a smaller roof and foundation.
Interiors and the hidden systems — wiring, pipes, ductwork — take more of the budget than the structure itself. That's why finish choices move the price so much.
Midrange, one story, two-car garage, average-cost area, 10% reserve. Every house needs a kitchen, baths and mechanical systems, so smaller homes spread those costs over fewer feet — but the total still drops.
Finish levels compared
Planning budgets for the same 2,400 sq ft one-story home with a two-car garage on a lot with city utilities in an average-cost area, with a 10% reserve and no land.
| Finish level | Planning budget | Per sq ft | Build time | What you get | Watch for |
|---|---|---|---|---|---|
| Builder grade | $451,500 | $188 | 7–11 months | Stock plans, laminate or basic quartz, vinyl plank | Upgrades priced one by one at the design center |
| Midrange | $564,500 | $235 | 7–11 months | Quartz or granite, hardwood in main rooms, better windows | Allowances that run short at selection time |
| Custom | $790,500 | $329 | 9–13 months | Architect plans, custom cabinets, unique layout | Design fees and change orders add up fast |
| Luxury | $1,186,500 | $494 | 11–15 months | Premium everything, complex rooflines, smart systems | Long lead times on specialty materials |
Construction loans, compared
A regular mortgage can't buy a house that doesn't exist yet. Construction loans pay the builder in stages, or draws, after an inspector confirms each stage is done, and you usually pay only interest on what has been drawn until the home is finished.
| Loan | Down payment | Closings | Fits best | Watch for |
|---|---|---|---|---|
| Construction-to-permanent | Often 10–20% | One | Most owner-hired builds | Rate may lock before the build starts |
| Two-time close | Varies | Two | Shopping for a better mortgage at move-in | Two sets of closing costs; must requalify |
| FHA one-time close | As little as 3.5% | One | Smaller down payments, modest credit | FHA loan limits and mortgage insurance |
| VA construction loan | 0% for eligible veterans | One | Veterans and service members | Few lenders offer it; builder must be approved |
| USDA single-close | 0% | One | Rural areas, moderate incomes | Income and location limits; eligible builders |
| Builder financing | Varies | One | Homes on the builder's own lots | Compare incentives against outside lenders |
What to do in your situation
🧓 You're building a smaller, single-level home for retirement
A 1,600 sq ft builder-grade one-story home with a two-car garage came to about $325,000 in our testing, before land. Plan it to work for the next 30 years now, when the changes cost almost nothing: a zero-step entry, 36-inch doorways, a curbless shower with wood blocking in the walls for grab bars, and the bedroom, bath and laundry on the main floor. Adding those later usually means tearing out finished work.
🌲 You're building on rural land
Before you buy, get a soil test (often called a perc test) to show the ground can handle a septic system, find out how deep wells run nearby, and ask the power company what it costs to bring service to your site. Those three answers can move the budget by tens of thousands of dollars — our rural-lot setting adds about $49,500. Rural buyers with moderate incomes may qualify for a USDA single-close loan with no down payment.
📈 Your builder wants a price-escalation clause
Material prices have been volatile, especially lumber. Canadian softwood, which supplies most U.S. lumber imports, now carries roughly 35% in anti-dumping and countervailing duties plus a 10% national-security tariff, and builders surveyed in 2025 estimated recent tariffs added about $10,900 to a typical home. If your contract lets the price rise with materials, cap the increase, name which items it covers, and require invoices as proof.
📝 You're choosing between fixed-price and cost-plus
A fixed-price contract sets the price up front, so a 5% reserve is usually enough — but read the allowances for cabinets, flooring and lighting, because going over them is on you. A cost-plus contract passes through actual costs plus a fee, which can be fair on a custom home but leaves you carrying the risk of overruns; choose a 15% reserve and ask for a guaranteed maximum price.
🛡️ You're worried the builder could fail mid-build
Never pay far ahead of finished work. Let your lender or a title company release draws only after inspection, and collect lien waivers from subcontractors and suppliers with each payment so nobody can file a lien on your home for money the builder didn't pass on. Check the builder's license, insurance and complaint history, and visit a home they finished at least a year ago.
🌀 You're building where hurricanes, hail or wildfire hit
Ask the builder to price a stronger roof — a sealed roof deck, ring-shank nails and impact-rated shingles — and, in wildfire areas, ember-resistant vents and noncombustible siding near the ground. These cost far less at framing than as retrofits, and in some states they earn insurance discounts. Get a homeowners insurance quote on the plans before you sign the build contract.
🏠 You still own the house you live in
Most lenders count your current mortgage when you qualify for a construction loan, so selling first may be the only way to borrow enough. If you sell before the new home is done, line up a rental with a flexible lease; building delays of a month or two are common. A bridge loan or home equity line can cover the gap, but you'll be carrying two housing payments.

Is my builder's bid fair?
Ask each builder for a line-item bid on the same plans, then divide it by the heated square footage — not the total under roof, which includes the garage and porches and makes the price per foot look lower. Set the calculator to the same size, finish level and lot, and compare. A bid far above the range should point to reasons you can see; one far below it usually has thin allowances or leaves out site work.
Quick answers
Is it cheaper to build or buy?
It depends on your market. Building lets you choose every detail and gets you a new warranty, but you also pay for the land, site work and months of construction-loan interest. Compare the full budget here with new homes for sale nearby.
How much of a new home's price is the land?
In builders' most recent national survey, the finished lot averaged about 14% of a new home's sale price and construction about 64%. In expensive metros the land share is often far higher.
Can I be my own general contractor?
Some owners do, and it can save the builder's fee, but lenders often require a licensed builder, and scheduling trades, inspections and deliveries is a full-time job for months.
Do barndominiums or modular homes cost less?
They can, mainly through faster framing or factory building, but foundations, utilities, finishes and site work cost about the same. Get bids for the same finished space before deciding.
What isn't in this estimate?
Furniture, window treatments, pools, closing costs, construction-loan interest and moving. Budget for them separately.
How the estimate works
The calculator starts from what builders reported spending per square foot on the average new home in the most recent national construction-cost survey, trended forward and grossed up for builder overhead and profit. It sets a rate for your finish level, adjusts for home size (smaller homes cost more per foot), stories and your local cost level, then splits the result into the eight stages builders report. It adds a basement or crawlspace upgrade, an attached garage, extra site work for rural or difficult lots, your reserve and any land price you enter. The range runs about 12% below to 22% above. These are planning allowances, not a builder bid.
