Pick how you want to estimate: by square footage, by room, or by building system.
Three input modes, one underlying pricing dataset. Switch any time — your number recalculates against the same 1.2M+ regional line items.
What's behind the numbers
A pricing dataset updated every month.
Every estimate you run on this page draws from the same dataset HomesBuilder uses internally across 9,300+ active builds. It's not scraped from listing aggregators — it's built from contractor invoices, regional material indexes, and our licensed project managers' field data.
Compared to contractor bids from a single general contractor, our owner-builder projects on HomesBuilder average $41,200 lower on a $380K build (2024 platform-wide analytics). That's the difference this estimator helps you find before you commit.
How to read your estimate
What it includes, what it doesn't, and what to do next.
The estimator is a planning number, not a contractor bid. Here are the four things most first-time users misread — and the four things you should actually do with the result.
What's included
Hard construction costs across six categories: site work & permits, foundation & framing, mechanical systems, interior finishes, exterior envelope, and regional contractor labor. All numbers are post-multiplier — your ZIP code has already adjusted the regional base rates.
What's not included
Land acquisition cost, financing carry, sales tax on materials (varies by state), well & septic (if applicable), and owner-supplied items like appliances or landscaping. We surface these as line items you add later — not as a hidden surprise.
How the range works
The low/high range reflects typical variance across vetted contractors in your region for the same scope. The midpoint is what owner-builders historically land within 6% of, when the project follows the 12-phase roadmap.
What to do next
Save the estimate, then convert it into a 12-phase build plan with matched contractors. The roadmap locks the scope, the contractor network quotes it, and the financing tool sizes the loan — all inside one account.
Next step
Got a number? Turn it into a build plan in under 10 minutes.
Save your estimate, and HomesBuilder converts it into a phased build plan — matched to vetted contractors in your ZIP code, with a financing pre-qualification at the end. Owner-builders using this flow save a platform-validated average of $41,200 on a $380K build.
FAQ
Estimator questions, answered plainly.
How accurate is the number, really?
For planning purposes, the midpoint is typically within 6% of what owner-builders actually spend when they follow the HomesBuilder 12-phase roadmap. This is a platform-validated average based on 2024 data across thousands of active builds — not a guarantee of any single project. For a binding figure, get three contractor bids through the vetted network.
Do you cover every U.S. state?
Yes — all 50 states, with regional sub-multipliers for major metros, suburbs, and rural counties. ZIP-code-level pricing adjustments apply across the dataset. HomesBuilder currently serves project owners in the United States only.
What's excluded from the estimate?
Land purchase, financing carry, sales tax on materials (state-dependent), well/septic systems, and owner-supplied items like appliances, lighting, or landscaping. We surface these separately so they don't get folded into a misleading single number.
What happens after I save my estimate?
Your estimate lands in your HomesBuilder account, pre-loaded into the 12-phase roadmap with regional contractor matches and a financing pre-qualification. From there you can move directly into planning, request contractor bids, or compare construction-loan quotes from 14 lenders.
