Home remodeling costs in 2026: whole-home renovations run $100,000–$300,000+, 300 sq ft additions $80,000–$200,000, basement finishing $30,000–$75,000, attic conversions $40,000–$100,000, and open-concept conversions $15,000–$50,000.
Scope and structural work dominate — moving walls, adding square footage, and touching mechanicals multiply cost fast. Finish level is the second lever: builder-grade vs. custom finishes can swing a project 40–60%. Age of home matters too — pre-1980 homes often hide code, asbestos, or structural surprises.
Lock the design before demolition, keep a 15–20% contingency, and resist scope creep — every "while we're at it" adds disproportionate cost once walls are open. For additions, confirm zoning setbacks and HOA rules before paying for architectural plans.

How we estimate costs
Cost ranges in this calculator start from typical U.S. homeowner project costs compiled from contractor rate surveys, material pricing data, and published project cost databases (base data updated Oct 2026). Your estimate is then adjusted three ways: a regional factor for your state's labor and material rates (e.g. California runs ~22% above the national average, Mississippi ~15% below), your quality choice, and project complexity.
Important: this is an educational estimate, not a quote. Actual prices vary significantly by location, contractor, material choices, and site conditions. Always get at least three written quotes from licensed contractors before starting a project.
Frequently asked questions
How much does a typical home remodeler project cost?
It depends on the project. For example, whole-home renovation typically runs $100,000–$300,000, while open-concept conversion ranges from $15,000 to $50,000. Use the calculator above for an estimate based on your project, finish, and complexity.
How accurate is this cost calculator?
These ranges start from national-average prices homeowners actually pay (base data updated Oct 2026), then adjust for your state's labor and material rates, your material quality choice, and project complexity. That gets you much closer than a flat national number — but your local market, home size, and site conditions still matter. Always get at least 3 written quotes before committing.
Why do contractor quotes vary so much?
Labor rates differ by region, overhead varies between solo operators and large firms, and material quality tiers change the price significantly. A quote 30–50% below the average is a red flag — it often means cut corners or missing line items.
Should I choose the cheapest quote?
Not necessarily. Compare what's included: materials, warranty length, timeline, and cleanup. The middle quote from a well-reviewed contractor is usually the best value.
