Whole House Renovation Cost Calculator
Whole house renovation cost varies from $15 per square foot for a cosmetic refresh to over $500 per square foot for a luxury gut renovation. This calculator takes your home size, scope of work (cosmetic, mid-range, full gut, or luxury), regional cost level, and major adds like kitchen and bathroom remodels, then returns a realistic budget including a contingency reserve. The result helps you set expectations, compare contractor bids, or decide whether to renovate versus move.
Whole House Renovation Cost Per Square Foot
The single most useful number in renovation budgeting is cost per square foot, which varies dramatically by scope:
| Scope | Whole house renovation cost per square foot |
|---|---|
| Cosmetic refresh (paint, flooring, fixtures) | $15-60 |
| Mid-range (kitchen, baths, new floors) | $100-200 |
| Full gut renovation (studs out, new systems) | $200-400 |
| Luxury / custom finishes | $400-600+ |
These ranges come from 2025 industry averages published by HomeAdvisor, Angi, and Remodeling Magazine's Cost vs Value Report. Your actual cost depends on:
- Scope of work, which is the biggest driver
- Regional labor and material costs
- Age and condition of the home (older homes often hide surprises)
- Finish level (stock vs custom cabinets, for example)
- Structural changes (moving walls, adding square footage)
What's Included at Each Scope Level
Cosmetic refresh covers paint, new flooring, new light fixtures, updated hardware, and maybe a refresh of kitchen cabinet fronts and counters. Systems stay in place. Budget: $15-60/sq ft.
Mid-range whole house renovation replaces flooring throughout, remodels the kitchen with new cabinets and countertops, updates 2-3 bathrooms, and refreshes paint and trim. Usually keeps existing walls and major systems. Budget: $100-200/sq ft.
Full gut renovation strips interior walls to studs, replaces all plumbing, electrical, HVAC, insulation, drywall, flooring, cabinets, fixtures, windows, and roof if needed. Common after a major flood or for homes that haven't been updated in 40+ years. Budget: $200-400/sq ft.
Luxury renovation adds high-end finishes: stone countertops, custom millwork, European appliances, spa bathrooms, smart home automation, and often an addition or reconfigured floor plan. Budget: $400-600+/sq ft.
Whole House Renovation Cost by Home Size
At mid-range scope ($150/sq ft base, excluding major adds):
| Home Size | Base Renovation Cost |
|---|---|
| 1,000 sq ft | $150,000 |
| 1,500 sq ft | $225,000 |
| 2,000 sq ft | $300,000 |
| 2,500 sq ft | $375,000 |
| 3,000 sq ft | $450,000 |
Add $40,000 for the kitchen, $15,000 per bathroom remodeled, $12,000-20,000 for a roof, and $8,000-25,000 for new windows.
Regional Cost Variation
The same renovation costs 35-60% more on the coasts than in rural markets. A $300,000 renovation in Kansas City lands at $255,000 in rural Alabama and $405,000 in downtown San Francisco. This calculator applies a multiplier of 0.85 (low), 1.0 (average), or 1.35 (high) based on your selection.
Contingency: Budget for the Unknown
Every renovation uncovers surprises: old wiring, rotted sills, asbestos, lead paint, plumbing behind walls. Industry practice is to reserve 10-20% of the total budget for contingency. Cosmetic jobs can get away with 10%; full gut renovations routinely need 20%.
Return on Investment
Per Remodeling Magazine's 2025 Cost vs Value Report, national average ROI at resale:
- Minor kitchen remodel: 96%
- Bathroom addition: 60%
- Major kitchen remodel: 49%
- Master suite addition: 56%
- Deck addition (wood): 83%
ROI is highest on curb appeal upgrades (entry door replacement, garage door, siding) and lowest on high-end master suite additions. Renovate for how you want to live, not purely for resale.
