Estimate the total cost of a home addition based on added square footage, addition type, finish level, regional cost factor, and structural complexity.

Estimate the cost to convert a garage into livable space using size, finish level, bathroom inclusion, insulation and HVAC needs, and regional labor/material cost differences.

Estimate the total cost of converting an attic based on floor area, conversion type, finish level, structural complexity, and location cost factor.

Estimate the total cost to finish a basement based on size, finish quality, bathroom addition, ceiling type, and regional labor/material cost differences.

Estimate the total cost of a bathroom remodel based on bathroom size, remodel scope, finish level, labor market, and whether plumbing fixtures stay in place.

Estimate the total cost of a kitchen remodel based on kitchen size, remodel scope, finish level, labor market, and whether you change the layout.

Estimate the total cost to renovate a room based on room size, renovation level, material quality, labor rate, and fixture budget.

Estimate the total cost of a home improvement project based on project size, material quality, labor rate, project complexity, and contingency.

Estimate the installed cost of gutter downspouts based on total length, number of downspouts, material, building height, and job complexity.

Estimate total roof surface area based on building footprint, roof pitch, number of roof sections, and eave overhang. Useful for planning roofing materials and project sizing.

Estimate the water flow capacity a gutter system should handle based on roof area, rainfall intensity, roof pitch, and downspout count. This helps size gutters for heavy rain conditions.

Estimate the recommended gutter width based on roof drainage area, roof pitch, local rainfall intensity, and the number of inside corners that increase water concentration.

Estimate total roofing material cost based on roof area, pitch, material type, waste factor, and roof complexity.

Estimate the total cost to replace a roof based on roof size, material type, tear-off layers, roof complexity, and regional labor pricing.

Estimate the total installed cost of a metal roof based on roof area, roof pitch, roof complexity, material type, and labor rate.

Estimate how many roofing squares and shingle bundles are needed for a roof based on roof area, roof pitch, waste allowance, and shingles per bundle coverage.

Estimate the total cost of a roofing project based on roof area, roof pitch, tear-off needs, material type, and roof complexity. The calculation applies a material cost per square foot and adjusts labor and installation effort using pitch and complexity factors, plus optional tear-off cost for replacing an existing roof.

Estimate total roof square footage using the home’s footprint, roof pitch, number of stories, and an overhang adjustment. This helps approximate roofing material needs by converting building footprint area into actual roof surface area.

Estimate the total board feet of lumber needed based on piece dimensions and quantity. Useful for pricing, material planning, and woodworking or framing projects.

Calculate roof slope from rise and run, with optional roof length and width to estimate roof area adjusted for slope.

Calculate roof pitch as rise over run and convert it to a slope angle in degrees using roof measurements. Enter the vertical rise and horizontal run to estimate the roof’s pitch ratio.

Calculate the sloped rafter length for a gable roof using the building span, roof pitch, overhang, and ridge board thickness. The calculator estimates the common rafter length from the ridge to the outside wall plus the overhang section.

Estimate the required rectangular beam section modulus based on span, uniform load, material, support condition, and allowable bending stress.

Estimate the required number of ceiling joists and total linear footage based on room dimensions and joist spacing.

Estimate the total number of floor joists needed for a rectangular floor area based on room length, room width, joist spacing, and an allowance factor for waste or extra framing.

Estimate the total number of wall studs needed for a framed wall based on wall length, wall height, stud spacing, number of openings, and corner style. The calculator includes end studs, additional studs for corners, and extra studs for door and window openings.

Estimate the number of wall studs needed for a framed wall based on wall length, stud spacing, wall height, number of corners, and number of openings. The calculation includes end studs, layout spacing, additional corner studs, and extra studs for rough openings.

Calculate lumber volume in board feet based on piece count, thickness, width, and length. One board foot equals a volume of 144 cubic inches, commonly calculated as thickness in inches multiplied by width in inches multiplied by length in feet divided by 12.

Estimate the total cost to build a stone wall based on wall size, thickness, stone type, labor rate, and site access difficulty.

Estimate the concrete volume needed for a rectangular footing in cubic yards based on footing length, width, depth, and quantity, with an allowance for waste.
