> Free construction calculators for materials, quantities, and project costs. 93 calculators and guides covering 175+ keywords. Location-specific cost estimates powered by BLS OEWS labor data for 393 US metros, DOE/IECC climate zones, BLS PPI material pricing, and Census ACS housing data.

## Cost Engine

All cost calculators use the same estimation engine:

- **Data source:** BLS Occupational Employment and Wage Statistics (OEWS), May 2024 release
- **Coverage:** 393 US metropolitan statistical areas, 13 construction trades
- **ZIP code lookup:** SmartML ZIP-to-CBSA crosswalk (33,000 ZIPs)
- **API route:** `/api/cost-data?zip=XXXXX&trade=TRADE_ID`
- **Labor burden:** 1.5× (payroll taxes, workers' comp, benefits)
- **Contractor markup:** 20% (overhead 10% + profit 10%)
- **Range calculation:** Low = 25th percentile wage, Mid = mean wage, High = 75th percentile wage

## Climate Zone Integration

**Data source:** DOE/IECC Climate Zone Map (county-level, 3,200+ counties mapped to 33,700+ ZIP codes)

ENERGY STAR R-value recommendations by zone (1–8) for attic, wall, floor, crawlspace. ZIP → county FIPS → IECC zone lookup. Used by insulation, roofing, and siding calculators.

| Zone | Label | Example Cities | Attic R-Value |
|------|-------|---------------|---------------|

## Material Price Indexing

**Data source:** BLS Producer Price Index via FRED API (monthly updates, 10 construction material series)

Calculators apply PPI adjustment factor to material cost estimates. Shows "prices as of [month/year]" for transparency. PPI factor = current index / 12-month-ago index.

| Category | FRED Series | Used By |
|----------|-------------|---------|
| Lumber & Wood | WPU081 | Deck, fence, home addition, basement, sunroom |
| Ready-Mix Concrete | WPU1321 | Concrete patio, driveway, foundation, retaining wall |
| Asphalt Roofing | WPU0552 | Roofing, asphalt driveway |
| Gypsum Products | WPU1392 | Drywall installation |
| Mineral Wool Insulation | WPU1017 | Insulation |
| Plywood | WPU083 | Siding installation |
| Paints & Coatings | WPU0621 | Interior/exterior painting |

## Housing Context

**Data source:** US Census Bureau ACS 5-Year Estimates (annual updates, ZIP-level)

Tables: B25035 (median year built), B25018 (median rooms), B25077 (median home value), B25040 (primary heating fuel). Used for renovation ROI context (e.g., "$25K kitchen remodel = 7% of $350K median home value") and smart defaults (e.g., "homes built before 1980 often have single-pane windows").
