Estimate Home Interior Cost
Analyze cost per square foot baseline, calculate kitchen and bathroom premiums, include furniture and utilities, and build comprehensive home interior budget. 5 steps, 45 minutes.
Key Challenge
Most people underestimate interior costs (forget furniture, utilities, contingency). Kitchen and bathrooms are disproportionately expensive. Comprehensive planning prevents budget shock.
What You'll Have
Baseline cost per square foot established for standard and premium finishes
Kitchen premium calculated (1.5–2× baseline) with appliance breakdown
Bathroom premium factored (1.2–1.5× baseline) with waterproofing
Furniture and utilities included (20–30% of total interior cost)
Comprehensive room-by-room budget with 15% contingency and phasing options

Why This Workflow Works
Interior cost estimation fails when people use single calculators per room without understanding premiums. Kitchen costs 1.5-2× baseline because of cabinetry and appliances. Bathrooms cost 1.2-1.5× due to waterproofing and fixtures. By anchoring to per-sqft baseline, then adding premiums for high-cost rooms, then factoring furniture and utilities, you get realistic budgets that don't shock mid-project. The contingency buffer (15-20%) accounts for discovered issues and price inflation. Phasing allows cash-flow management across 2-3 years. This workflow prevents two common mistakes: underestimating by forgetting furniture, or overestimating by using premium costs everywhere.
