How much does it cost to build a house in the US in 2025?

The national average cost to build a new single-family home in the US in 2025 ranges from $140–$160 per square foot for basic construction to $250–$400 per square foot for premium custom homes. Costs vary significantly by state — California and Hawaii are 55–85% above the national average, while Mississippi, Arkansas, and Oklahoma are 15–20% below.

How many studs do I need for a 2000 square foot house?

A 2,000 square foot, two-story house with standard 9-foot ceilings typically requires 600–800 studs total — approximately 400–450 exterior wall studs (2x6) and 200–350 interior wall studs (2x4), depending on the floor plan complexity and stud spacing.

How do I calculate how many drywall sheets I need?

Calculate your total wall area: room perimeter × ceiling height. Add ceiling area. Subtract door openings (21 sq ft each) and window openings (15 sq ft average). Divide by 32 (for 4x8 sheets) or 48 (for 4x12 sheets). Add 10% for waste and cuts. Our free drywall calculator above does this automatically.

DRYWALL SHEETS

How many sheets for a room, floor, or whole house?

Length (ft)

Width (ft)

Ceiling Height

Sheet Size

Doors

Windows

Waste Factor

Drywall Sheets:0 sheets

Coverage Area:0 sq ft

Pallets (52/pallet):0

Joint Compound:0 buckets

Paper Tape:0 rolls

wall_area = 2 * (L + W) * H
deductions = (doors * 21) + (windows * 15)
net_area = wall_area + (L * W) - deductions
sheets = CEIL(net_area / sheet_area * (1 + waste))

CONCRETE BAGS

For slabs, footings, fence posts, or steps.

Application

Length (ft)

Width (ft)

Thickness

Bag Size

Volume Needed:0 cubic yards

Required Bags:0 bags

Overage (5% waste):Included

Note: Bagged concrete is recommended for this volume.

cubic_feet = L * W * (thickness/12)
cubic_yards = (cubic_feet / 27) * 1.05
bags = CEIL(cubic_yards / BAG_YIELDS[bag_size])
Bag Yields: 80lb = 0.022 CY, 60lb = 0.017 CY, 40lb = 0.011 CY.

LUMBER BOARD FEET

Calculate board feet for any lumber order.

Enter custom dimensions

Lumber Size

Actual: 1.5" × 3.5" · Standard framing studs.

Length (ft)

Quantity

Per Piece:0 BF

Total Board Feet:0 BF

MBF Value:0.000 MBF

Est. Cost (@$600/MBF):$0

board_feet = (Thickness_nominal * Width_nominal * Length_ft) / 12
total_BF = board_feet * quantity
MBF = total_BF / 1000
Note: Board feet are calculated using **nominal** dimensions, not actual finished sizes.

ROOFING SQUARES

Estimate shingles, underlayment, and drip edge.

Length (ft)

Width (ft)

Roof Pitch

Style

Overhang (inches)

Roof Squares (100 SF):0 Sqs

Shingle Bundles (3/sq):0 bundles

Underlayment Rolls:0 rolls

Ice & Water (eaves):0 sq ft

Perimeter Drip Edge:0 LF

adj_area = (L + overhang)* (W + overhang)
roof_area = adj_area * pitch_factor * style_factor
squares = roof_area / 100
bundles = CEIL(squares * 3)

PAINT GALLONS

Calculate for walls, trim, or siding.

Surface Type

Length (ft)

Width (ft)

Coats

Gallons/Coat:0.0 gal

Total Paint:0 gal

Drywall Primer needed:0 gal

net_area = total_area - deductions
gallons = CEIL(net_area / coverage_rate) * coats * 1.10
Smooth surfaces cover ~350-400 SF/gal. Porous brick covers ~150 SF/gal.

INSULATION SELECTOR
