Step 1
Project base $/sqft
We start from 2024 mid-point $/sqft for ten common project types — kitchen, bath, basement finish, addition, roof, siding, and more. Numbers are pulled from the Cost vs. Value report and HomeAdvisor's True Cost Guide.
Home Improvement Calculators
Most contractor estimates swing 3× on the same square footage because nobody agrees on what "standard finish" means in your ZIP code. This calculator pins the math to 2024 national medians × your region × your finish level, so you walk into the bid conversation already knowing the fair range.
Plug in a project, its square footage, the finish level, and your region. We multiply 2024 national $/sqft medians by regional and complexity factors to give you a planning range.
Planning estimate
$57,500
Mid-scope total for a 200 sqft kitchen remodel in the East North Central region at standard finish, including a 15% contingency.
Mid-range: refaced cabinets, quartz counters, mid-tier appliances. Upscale: full custom cabinetry, stone counters, premium appliances, structural changes.
Standard finish: Mid-tier finishes, some layout tweaks, name-brand fixtures and appliances.

Basic finishes run 0.75×, standard 1.0×, upscale 1.65×. Regional multipliers span 0.88× (East South Central) to 1.22× (Pacific). Same square footage, very different invoice.
Step 3
Every real remodel hits unknowns — rotted sheathing, out-of-code wiring, delayed cabinets. Industry convention is a 10–20% buffer; we budget 15% by default.
Grounded in the 2024 Cost vs. Value Report, HomeAdvisor's True Cost Guide, and the multipliers used by the calculator above.
A 10×10 kitchen is 100 sqft. At the 2024 national mid-point of about $250 per sqft for a standard-finish kitchen, you're looking at roughly $25,000 in base scope before contingency. Shift to builder-grade finishes and it drops to around $15,000; push to upscale custom cabinetry and stone it climbs past $50,000. Add a 10–20% contingency on top.
Cabinets alone are a subset of a basic-scope kitchen remodel, so yes — cabinets-only is almost always cheaper. A refaced or replaced cabinet project typically lands near the low end of our basic kitchen range (around $150 per sqft × your layout), while a full remodel that also touches counters, appliances, plumbing, and electrical pushes past $250 per sqft at mid-scope. If the layout works and the boxes are sound, cabinets-only is the higher-ROI move.
Industry convention is 10–20% of base cost. Renomath defaults to 15%, which covers the unknowns that show up once walls open — rotted sheathing, out-of-code wiring, plumbing reroutes, and the inevitable material price creep between bid and install. Older homes and structural changes lean closer to 20%; in-kind refreshes can get away with 10%.
At 2024 national averages: about $125 per sqft for a basic refresh, $250 per sqft at a standard mid-range scope, and up to $550 per sqft for upscale work with custom tile, frameless glass, heated floors, and layout changes. Apply your regional multiplier (0.88× to 1.22×) on top. A typical 40-sqft hall bath at standard finish runs roughly $10,000 before contingency.
Almost always, yes. Any time a basement finish involves framing, drywall, electrical runs, plumbing rough-ins, or egress window changes, your local building department will require a permit and inspections. Cosmetic-only work (paint, flooring over existing slab) is often the exception. Permit fees are typically 0.5–2% of project cost — budget for them inside your base scope, not your contingency.
At standard finish on the national average, 200 sqft × $250 per sqft = $50,000 base cost, plus a 15% contingency lands you near $57,500. Move to the Pacific region (1.22×) at upscale finish (1.65×) and the same 200 sqft climbs past $115,000 all-in. Plug your exact region and finish into the calculator above for a scenario-specific number.
Per Remodeling Magazine's 2024 Cost vs. Value Report, a minor midrange kitchen remodel typically recoups about 85% of its cost at resale on a national average, while a major midrange kitchen remodel recovers closer to 49%. Upscale kitchens almost always return less than mid-range. ROI is higher when the existing kitchen is badly dated, lower when you're already at market-standard finish.
Same project, very different invoice depending on where you build. Renomath normalises the U.S. national average to 1.00, then applies the Cost vs. Value regional rollups: East South Central (AL, KY, MS, TN) at 0.88×, Pacific (CA, OR, WA) at 1.22×, New England at 1.18×. A $50,000 project in Nashville becomes a $61,000 project in Seattle — nothing changed except ZIP code.
We multiply the base $/sqft by 0.75× for basic, 1.0× for standard, and 1.65× for upscale. Basic = builder-grade finishes, in-kind replacement, minimal structural changes. Standard = mid-tier fixtures and appliances, some layout tweaks. Upscale = custom cabinetry or tile, stone counters, premium fixtures, structural or layout changes. The scope — not just the materials — is what actually moves the multiplier.
A primary suite addition is new footprint, which runs $130–$400 per sqft at 2024 national averages depending on finish level and whether the suite includes a full bath (it usually does). A 300 sqft bed-plus-bath addition at standard finish averages around $66,000 base; the same scope at upscale in a Pacific-region market pushes past $160,000 before contingency.
A HELOC or cash-out refi makes sense when you have the equity, want a simple draw, and the scope is predictable. A renovation loan (FHA 203(k), Fannie Mae HomeStyle, or a bank construction-to-perm) is the right call when you need to roll the remodel cost into a purchase, when projected after-repair value is load-bearing on the approval, or when scope exceeds your available equity. Talk to a lender before choosing — pricing and draw schedules differ materially between products.
A standard remodel bid typically includes labor, subcontractors, materials spelled out in the scope, dumpster and cleanup, and permit fees. It usually excludes: appliances the homeowner picks out separately, design or architecture fees, sales tax on client-supplied materials, change orders, and anything hidden behind drywall that hasn't been exposed yet. Read the exclusions page — that's where a "cheap" bid becomes an expensive one.
