Formula Sequence
- 1. Area with waste:
area_sqft * (1 + waste_factor) - 2. Boxes needed:
ceil(area_with_waste / sqft_per_box) - 3. Materials subtotal:
boxes_needed * material_cost_per_boxplus accessories - 4. Labor subtotal:
area_sqft * labor_rate_per_sqft * region_multiplier - 5. Subfloor subtotal: none, minor, or major prep band
- 6. Final range: total with uncertainty adjustment for site variability
Assumptions
| Input | Value | Note | Source |
|---|---|---|---|
| Waste factor bands | 5%, 10%, 15% | Depends on layout complexity, installer skill, and pattern. | RenoCost Pricing Model v3.1 Updated 2026-02-16 |
| Subfloor cost bands | $0 to $4 per sq ft | Covers none, minor leveling, or major prep scenarios. | RenoCost Pricing Model v3.1 Updated 2026-02-16 |
| Material units | Box-based purchasing | All quantities round to full boxes for procurement realism. | RenoCost Pricing Model v3.1 Updated 2026-02-16 |
| Labor baseline | Type-specific per sq ft rates | Tile and hardwood carry highest labor assumptions. | RenoCost Pricing Model v3.1 Updated 2026-02-16 |
| Regional sensitivity | Labor weighted | Location impacts labor more than base material pricing. | RenoCost Pricing Model v3.1 Updated 2026-02-16 |
| Price uncertainty | +10% to +20% | Accounts for removal, transitions, and site-specific complexity. | RenoCost Pricing Model v3.1 Updated 2026-02-16 |
