Getting an accurate renovation estimate used to mean calling multiple contractors and waiting days for quotes. Our free renovation calculator gives you an instant state-adjusted cost range in 60 seconds — no email, no signup, no contractor visit required. Here is everything you need to know about how it works and how to use it.
How accurate is it? Our estimates are based on aggregated national contractor data adjusted for state labor costs and local material prices. Expect real contractor quotes to fall within 15–25% of our midpoint estimate in most US markets.

Full renovation, partial update, or cosmetic refresh. Cabinet, countertop, and appliance costs included.
Half bath, full bath, or master bath. Plumbing, tile, vanity, and fixture costs modeled separately.
Flooring, closet systems, painting, and trim work. Ideal for staging or livability improvements.
Hardwood or LVP flooring, painting, fireplace, and built-in shelving cost estimates.
Full finishing including framing, drywall, electrical, flooring, and bathroom rough-in options.
Asphalt, metal, and premium material options. Sized by total roof area, not room size.
Insulation, drywall, epoxy flooring, and garage door replacement cost estimates.
State-specific labor multipliers for all 51 jurisdictions including Washington DC.
Every estimate is built from three inputs you provide — room type, room size, and your state — combined with our internal cost database.
Each room type has a different cost model because the trades involved are different. A bathroom renovation is dominated by plumbing and tile labor. A kitchen is dominated by cabinetry and countertops. A basement is dominated by framing and electrical. Selecting the correct room type ensures you get estimates based on that room's actual cost drivers.
Renovation costs scale with room size, though not linearly. There is a base cost for any project (mobilization, permits, contractor overhead) plus a per-square-foot cost for materials and labor. Our model applies both to calculate a realistic total.
Labor costs vary dramatically across the US. A licensed contractor in San Francisco earns $85–$120/hour. The same contractor in rural Mississippi earns $35–$55/hour. We apply state-specific labor multipliers based on Bureau of Labor Statistics data to adjust every estimate for your local market.
Our three quality tiers reflect real market segments:
Your renovation estimate from our calculator serves as a benchmark — the market rate for your specific project in your state. Here is how to use it effectively:
| Room | Typical US range | National average |
|---|---|---|
| Kitchen (200 sq ft, mid-range) | $14,000–$42,000 | $24,000 |
| Bathroom (full, mid-range) | $8,000–$28,000 | $13,000 |
| Master bathroom (premium) | $18,000–$55,000 | $30,000 |
| Basement (1,000 sq ft, standard) | $18,000–$40,000 | $26,000 |
| Bedroom (200 sq ft) | $4,000–$15,000 | $7,500 |
| Living room (300 sq ft) | $5,000–$18,000 | $9,500 |
| Roof (1,500 sq ft, asphalt) | $6,500–$16,000 | $10,500 |
| Garage (standard) | $4,000–$15,000 | $8,000 |
The single biggest driver of renovation cost variation is local labor rates. Here is a comparison of the same standard kitchen renovation (200 sq ft, mid-range quality) across US states:
| State | Estimated cost | Compared to average |
|---|---|---|
| Hawaii | $35,500 | +48% |
| California | $33,100 | +38% |
| New York | $34,100 | +42% |
| Texas | $22,800 | avg |
| Florida | $23,300 | avg |
| Ohio | $21,100 | -12% |
| Mississippi | $18,500 | -23% |
| Arkansas | $18,700 | -22% |
Quality varies significantly. Calculators that do not adjust for state labor costs are often inaccurate by 20–40% for users in high or low cost states. Our calculator applies state-specific multipliers based on current BLS data, making it significantly more accurate than flat national average tools.
No — our free calculator gives you a market-rate baseline estimate without any contractor contact. You can use this to determine whether a project fits your budget before investing time in contractor meetings. When you are ready to hire, the estimate helps you evaluate quotes objectively.
Several factors cause differences: your specific room's unique conditions (non-standard dimensions, accessibility challenges, existing damage), material choices that differ from the standard tier you selected, local market conditions in your specific city vs. state average, and contractor-specific overhead and profit margins. A 15–25% difference from our estimate is normal. Differences over 40% warrant investigation.
