Renovation Cost Data & Sources

Real Renovation Cost Ranges (2025–2026)

National averages and typical ranges from published industry cost guides. Costs rise yearly with material and labor prices, and vary 20–30% or more by region. Use these as planning brackets, not as quotes.

Project	Typical total range	$/sq ft	Source (year)
Kitchen remodel	$14,588–$41,550 (avg ~$26,946); minor $10k–$20k, major $20k–$65k, complete $65k–$130k+	$75–$250	HomeAdvisor/Angi (2025)
Bathroom remodel	$6,639–$17,622 (avg ~$12,121); minor $3k–$10k, partial $10k–$25k, full $25k–$80k	$70–$250	Angi (2025)
Basement remodel / finish	$12,009–$34,633 (avg ~$22,869); luxury >$120/sq ft	$30–$75	Angi (2025)
Flooring installation	~$12.50/sq ft avg; hardwood $6–$25, laminate $3–$13, tile $15–$20 (installed)	$3–$25	Angi (2025)
Deck (pressure-treated)	$25–$40/sq ft installed; composite $45–$65/sq ft; national avg deck $7,000–$23,000	$25–$65	HomeAdvisor/Angi (2025)
Window replacement	$300–$2,500 per window (avg ~$750); full home (10–15) $4,500–$22,500	—	Angi (2025)
Home addition (single-story)	$80–$200/sq ft; second-story $100–$300/sq ft; 1,000 sq ft addition $80k–$210k	$80–$300	HomeAdvisor (2025)
New home construction (context)	Avg construction cost $428,215 (~$162/sq ft) for ~2,647 sq ft; construction = 64.4% of sale price	~$162	NAHB (2024)

Window figure is an average; a November 2025 survey by This Old House placed the national average at about $477 per window. Regional multipliers can swing any of the above ranges 20–30%+.

ROI & Resale Value (Remodeling Magazine / Zonda Cost vs. Value, 2025)

Project	Typical cost recovery (ROI)
Minor kitchen remodel (midrange)	~96%
Bathroom remodel (midrange)	~60–70%
Basement remodel	63.4%
Garage door replacement	336.6%
Steel entry door replacement	219.8%
Manufactured stone veneer	200.7%
Wood deck addition	~52%
Composite deck addition	~40%

How the RenoFig Calculators Are Calibrated

Our calculators use two kinds of real, adjustable parameters so you can tune estimates to your situation. These are illustrative baselines, not fixed quotes — final pricing always comes from local contractors.

1. Finish-grade baselines (per-square-foot rates)

Room calculators let you pick a finish grade — Basic / Standard / High-End — which maps to a per-square-foot bracket. These brackets are calibrated to the industry cost-guide ranges in the table above (e.g., basement finishing at ~$30 / $55 / $90 per sq ft for basic / standard / high-end tiers, within Angi's published $30–$75/sq ft range). Labor is modeled as a share of subtotal (roughly 35–45%), consistent with industry reporting that labor is ~25–65% of a remodel depending on trade.

2. State cost-difference multipliers (regional coefficient)

The State Cost Difference tool applies a real regional multiplier to a base cost. The multipliers reflect higher-cost coastal states and lower-cost southern / Midwestern states relative to a national average of 1.0 (Texas):

State	Multiplier	State	Multiplier
California	1.25	North Carolina	0.98
New York	1.20	Florida	0.95
Massachusetts	1.15	Georgia	0.93
New Jersey	1.12	Ohio	0.90
Washington	1.10	Michigan	0.88
Maryland	1.08	Alabama	0.85
Illinois	1.05	Mississippi	0.82
Virginia	1.03	Arkansas	0.82
Texas (avg)	1.00

3. Industry references (methodology, not republished figures)

• RSMeans (Gordian) — the industry-standard commercial unit-cost database. It is a paid data service, so we use it as a calibration reference for per-square-foot baselines rather than republishing its proprietary figures. rsmeans.com
• NAHB — stage-cost shares for new construction (interior finishes 24.1%, major systems rough-ins 19.2%, framing 16.6%, exterior finishes 13.4%, foundations 10.5%, site work 7.6%, final steps 6.5%) inform our budgeting breakdowns. nahb.org

Practical Steps: Estimate Your Renovation Budget

1. Define scope. Decide minor / partial / full. Scope is the single biggest cost driver — a minor kitchen refresh ($10k–$20k) costs a fraction of a full gut ($65k+).
2. Start from a per-square-foot bracket. Pick the room type from the cost table above (e.g., bathroom $70–$250/sq ft) and multiply by your actual square footage.
3. Add line items. Cabinets, labor, permits, fixtures, and finishes. Budget labor at roughly 25–65% of total depending on trade; permits commonly $500–$2,000 for structural/electrical/plumbing work.
4. Add a 10–20% contingency. Older homes and projects tying into existing structures routinely surface surprises once walls open.
5. Get at least three written bids. Compare allowances and exclusions (what is not included), payment schedules, and license/insurance — not just the bottom-line number.

Practical Steps: Compare Contractor Quotes

• Read each bid line by line; match the same scope before comparing totals.
• Watch for allowances (e.g., "$3,000 for cabinets") vs. fixed selections — low allowances cause change orders later.
• Confirm permit, debris removal, and cleanup are included.
• Verify license, insurance, and local references; avoid large upfront deposits.
