Home Replacement Cost Calculator (2026)
Estimate what it would actually cost to rebuild your home from the foundation up — using current labor, materials, and regional construction costs. Cross-check the number your insurer is using before the next claim.

How this is calculated
The cost approach. Replacement cost = $/sqft × square footage × regional multiplier × structural adjustments. Baseline cost tiers: $165 basic / $230 standard / $320 custom / $450 luxury. Regional multipliers: West Coast & New England 1.20–1.25×, Mountain West 1.05×, Mid-Atlantic 1.05×, Midwest & Southeast 0.95×. Multi-story adds 8%, basement adds 7%, and each garage stall adds $12,000.
What this misses. Custom finishes (imported stone, smart-home systems, in-floor heating), local labor shortages, and post-disaster material spikes can push real rebuild cost 15–40% above baseline. For high-value or custom homes, get a contractor's per-square estimate or a certified replacement cost appraisal before relying on any calculator number — including ours.

Frequently asked questions
How is home replacement cost calculated?
Replacement cost uses the cost approach: cost per square foot for your construction quality × square footage × regional labor/materials multiplier, plus add-ons for additional stories, basements, garages, and high-end finishes. It's the cost to rebuild from the foundation up using today's labor and materials — completely independent of market value or what you paid for the home.
What's a typical replacement cost per square foot in 2026?
Rough national bands in 2026: $165/sqft for basic tract construction, $230/sqft for standard, $320/sqft for custom, and $450/sqft for luxury. West Coast and New England run 20–25% higher; the Midwest and Southeast run about 5% lower. Post-disaster demand surges can push numbers 30–50% above baseline in a region for 12–24 months.
Is replacement cost the same as market value?
No. Market value includes the land, the neighborhood, school districts, and buyer demand — none of which homeowners insurance pays to rebuild. Replacement cost is construction-only. In hot markets, replacement cost can be 30–50% lower than market value; in cooled markets it can be higher. Use replacement cost (not market value or what you paid) to size your dwelling coverage.
How accurate are insurance replacement cost calculators?
Carrier estimators like Marshall & Swift and Verisk 360Value rely on partial property data — they often miss custom finishes, basement build-outs, and recent material cost spikes. Independent studies find 10–25% of homes are underinsured against true rebuild cost. This calculator is a sanity check; for binding numbers, get a contractor's per-square estimate or a certified replacement cost appraisal.
How often should I recalculate replacement cost?
At every renewal, after any remodel, and whenever your area experiences a major disaster (hail, hurricane, wildfire) that spikes regional construction demand. Rebuild costs rose ~30% nationally between 2020 and 2024 — a policy you bought five years ago is almost certainly underinsured today.
Why is my insurer's replacement cost number different from this calculator?
Carriers use proprietary cost databases (Marshall & Swift, Verisk 360Value, CoreLogic) that pull from public records, which miss interior upgrades and assume standard finishes. They also lag on post-disaster material spikes by 6–18 months. If your number is materially lower than this calculator's range, ask your agent for the line-item rebuild estimate and have a contractor sanity-check it.
Does replacement cost include the foundation, driveway, and landscaping?
Replacement cost (Coverage A) covers the dwelling itself: foundation, framing, roof, finishes, mechanical systems. Detached structures (sheds, fences, detached garages) fall under Coverage B (Other Structures), typically capped at 10% of Coverage A. Landscaping has a separate sub-limit, usually $500 per item up to 5% of dwelling.
