Monthly payment calculations shown in this tool use standard amortization formulas for the total project cost (not the Boxabl unit alone) and are estimates only.

Cost Calculator FAQs
What does a Boxabl project cost all-in?
Beyond the unit itself (roughly $20,000 for the upcoming Baby Box to $99,000+ for the 2-Bed Casita), plan for foundation construction ($5,000–$25,000 by type and region), engineering plans (from $749), permits ($500–$3,000 by jurisdiction), and site setup/utilities ($3,000–$15,000). The calculator on this page lets you build your own estimate line by line.
What's the cheapest foundation for a Boxabl?
Pier & beam and slab-on-grade are typically the most economical, starting around $5,000–$6,000 in low-frost regions. Deep-frost states push costs up because footings must bear below frost depth — see your state's guide for specifics.
Does the estimate include the Boxabl unit price?
The unit price is shown for reference only — you purchase the unit directly from Boxabl Inc. We provide the foundation engineering. Unit prices shown are Boxabl's advertised estimates and change over time.
How accurate is this calculator?
It's a planning tool using national typical ranges. Your actual costs depend on soil, site access, local contractor market, and jurisdiction fees. For a professional, parcel-specific answer, our $299 Site Feasibility Report includes a 30-minute PE consultation.
