Calculates the number of roofing squares needed to cover a roof, including a user-defined waste allowance. Use this when ordering shingles for a new roof or a re-roofing project.
Deck Joist Spacing Calculator
Calculates the number of joists needed across a deck's width based on the on-center spacing. Use this when planning deck framing to ensure structural adequacy and code compliance.
Pipe Pressure Loss Calculator
Estimates pressure loss due to friction in plumbing pipes based on length, flow rate, and diameter. Use this when sizing pipes for water supply systems, irrigation, or fire protection layouts.
Steel Beam Weight Calculator
Calculates the total weight of a steel I-beam based on its length and per-foot weight rating. Use this when estimating structural loads, crane capacities, or freight costs for steel orders.
Concrete Volume & Cost Calculator
Estimate how many cubic yards of concrete you need for a slab, pad, or footing — plus total material cost with waste and delivery. Ideal for DIYers and contractors planning pours.
Roofing Materials Cost Calculator
Estimate total roofing material cost for any pitched roof by entering footprint dimensions, roof pitch factor, material price, and waste allowance. Perfect for re-roofing bids and new construction.
Drywall Materials Calculator
Count the exact number of drywall sheets needed for walls and ceiling of a room, minus door and window openings, with a 10% waste allowance built in. Great for estimating before a trip to the lumber yard.
Excavation Cost Calculator
Estimate earthmoving volume in cubic yards and total excavation cost by entering pit dimensions, soil difficulty, and contractor pricing. Useful for foundations, pools, and utility trenches.
Insulation Cost Calculator
Estimate insulation material cost for walls, attics, or floors based on area, target R-value, insulation type, and installation method. Helps homeowners and contractors budget energy-efficiency upgrades.
Flooring Cost Calculator
Estimate the total cost of flooring a room, including materials, installation, and waste. Use it when budgeting for hardwood, laminate, tile, or vinyl flooring projects.
Paint Coverage Calculator
Calculate the exact number of paint gallons required for any surface area, factoring in multiple coats and a configurable waste allowance. Useful for both DIY painters and professional contractors bidding jobs.
HVAC Load Calculator
Estimate the heating or cooling capacity (BTUs) your room needs based on size, ceiling height, insulation, and climate. Use this before sizing an air conditioner, heat pump, or furnace.
Concrete Volume Calculator
Find out exactly how many cubic yards of concrete you need for a slab, footing, or pad. Accounts for thickness and a configurable waste allowance so you never fall short on pour day.
Roofing Materials Calculator
Estimate the number of roofing squares (100 sq ft each) of shingles and underlayment needed for a roof job, factoring in pitch and waste. Use it when planning a re-roof or new construction.
Drywall Calculator
Determine how many drywall sheets you need to cover all walls and the ceiling of a room, with automatic deductions for doors and windows. Great for budgeting before any renovation or new build.
Lumber Cost Calculator
Calculates the number of studs and total lumber cost for framing a wall based on stud spacing, wall length, and current board-foot pricing. Use it when budgeting a framing project before purchasing materials.
