  • calc_concrete_slab Estimate ready-mix cubic yards or the number of 80 lb bags for a rectangular slab, patio or driveway. Formula: Cubic yards = Length(ft) × Width(ft) × Thickness(in)/12 ÷ 27 × (1 + waste%). Bags = cubic feet ÷ bag yield.
  • calc_concrete_column Concrete needed for round columns, piers and tube forms (sonotubes). Uses cylinder volume, which differs from slab math. Formula: Cubic feet = π × (diameter(in)/24)² × height(ft) × count; cubic yards = cu ft ÷ 27 × (1 + waste%).
  • calc_concrete_footing Volume for continuous trench/wall footings where width is in inches and length runs the full perimeter. Formula: Cubic yards = Length(ft) × Width(in)/12 × Depth(in)/12 ÷ 27 × (1 + waste%).
  • calc_paint Gallons of wall paint from room perimeter and height, minus doors and windows, for any number of coats. Formula: Paintable area = perimeter × height − 20 sq ft per door − 15 sq ft per window. Gallons = area × coats ÷ label coverage.
  • calc_roofing Roof area from the house footprint and pitch, converted to roofing squares (100 sq ft) and shingle bundles. Formula: Pitch factor = √(1 + (rise/12)²). Roof area = (L + 2×overhang) × (W + 2×overhang) × pitch factor. Squares = area ÷ 100 × (1 + waste%).
  • calc_drywall Number of drywall sheets for walls and optionally the ceiling. Formula: Sheets = (perimeter × height + ceiling area) × (1 + waste%) ÷ sheet area.
  • calc_flooring_tile Square footage plus waste and number of boxes for tile, laminate, vinyl plank or hardwood. Formula: Area = L × W; to buy = area × (1 + waste%); boxes = to buy ÷ coverage per box.
  • calc_mulch_gravel Cubic yards (and optional tons) of mulch, gravel, sand or soil for a bed or path. Formula: Cubic yards = L(ft) × W(ft) × depth(in) ÷ 324 (since 27 cu ft × 12 in = 324). Tons = cu yd × supplier density.
  • calc_voltage_drop Voltage drop for a single- or three-phase run using NEC Chapter 9 Table 8 conductor sizes. Formula: VD = 2 × K × I × L ÷ CM (single phase) or √3 × K × I × L ÷ CM (three phase); K = ohm·cmil/ft (approx. 12.9 Cu, 21.2 Al); CM from NEC Ch. 9 Table 8.
  • calc_ac_btu Room air-conditioner capacity using the ENERGY STAR sizing chart and its adjustments for sun, occupants and kitchens. Formula: Base BTU from the ENERGY STAR area chart; −10% heavily shaded, +10% very sunny, +600 BTU per person above 2, +4,000 BTU for a kitchen.
  • calc_deck_board Number of deck boards for a rectangular deck, accounting for board width and gap. Formula: Rows = ⌈width(in) ÷ (board width + gap)⌉; boards = rows × ⌈deck length ÷ board length⌉ × (1 + waste%).
  • calc_fence Posts, rails and pickets for a straight run of wood privacy or picket fence. Formula: Sections = ⌈length ÷ spacing⌉; posts = sections + 1 + gates; pickets = ⌈length(in) ÷ (picket width + gap)⌉.
  • calc_insulation_r_value Thickness needed to reach a target R-value for the R-per-inch printed on your insulation product. Formula: Thickness(in) = target R ÷ R per inch. Volume in board feet = area(sq ft) × thickness(in).
  • calc_pool_volume Gallons in a rectangular pool with a sloped bottom, using average depth. Formula: Gallons = L × W × (shallow + deep)/2 × 7.48052 gal/cu ft.
  • calc_round_pool_volume Gallons in a round or above-ground pool. Formula: Gallons = π × (D/2)² × average depth × 7.48052 (≈ D² × depth × 5.875).
  • calc_oval_pool_volume Gallons in an oval (elliptical) pool. Formula: Gallons = π × (L/2) × (W/2) × average depth × 7.48052.
  • calc_solar_panel Panels needed to offset annual electricity use, from panel wattage, peak sun hours and system losses. Formula: Annual kWh per panel = W/1000 × peak sun hours × 365 × (1 − losses). Panels = ⌈annual use ÷ kWh per panel⌉.
  • calc_board_foot Board feet and cost for hardwood or dimensional lumber. Formula: Board feet = thickness(in) × width(in) × length(ft) ÷ 12 × pieces (one board foot = 144 cubic inches).
  • calc_asphalt Tons of hot-mix asphalt for a driveway or lot from area, compacted depth and mix density. Formula: Tons = L × W × depth(in)/12 × density(lb/cu ft) ÷ 2,000.
  • calc_stair_stringer Number of risers and treads, exact riser height, total run and stringer length from the floor-to-floor rise, checked against the IRC 7¾ in maximum riser. Formula: Risers = ⌈total rise ÷ max riser⌉; riser height = total rise ÷ risers; treads = risers − 1; total run = treads × tread depth; stringer le
  • calc_rafter_length Common rafter length, ridge rise and roof angle from the horizontal run and pitch, with optional overhang. Formula: Pitch factor = √(1 + (rise/12)²). Rafter length = (run + overhang) × pitch factor. Ridge rise = run × rise ÷ 12. Angle = atan(rise ÷ 12).
  • calc_wall_stud Studs at 16 or 24 in on center for a wall length, plus extras for corners and openings, and linear feet of top and bottom plate. Formula: Studs on layout = ⌈length(in) ÷ spacing⌉ + 1; total = layout + corners × extras per corner + openings × extras per opening. Plate linear ft = length × plates.
  • calc_brick Bricks for a single-wythe wall from its area, the brick face size and the mortar joint. Defaults are a modular brick with a ⅜ in joint. Formula: Bricks per sq ft = 144 ÷ ((length + joint) × (height + joint)); bricks = (wall area − openings) × bricks per sq ft × (1 + waste%).
  • calc_concrete_block Number of 8×8×16 concrete blocks (CMU) for a wall. A standard block plus a ⅜ in joint covers 16 × 8 in, so about 1.125 blocks per square foot. Formula: Blocks per sq ft = 144 ÷ ((length + joint) × (height + joint)) = 144 ÷ (16 × 8) = 1.125 for standard units; blocks = net wall area × 1.125 × (1 + wa
  • calc_paver Number of pavers for a patio, walkway or driveway plus cubic yards of compacted base and bedding sand. Formula: Pavers per sq ft = 144 ÷ (paver length × width); pavers = area × per sq ft × (1 + waste%). Base and sand cubic yards = area × depth(in) ÷ 324.
  • calc_sod Square feet of sod, number of pieces and pallets for a lawn area. Piece size and pallet coverage are editable because they vary by farm and grass type. Formula: Sq ft to buy = L × W × (1 + waste%); pieces = sq ft ÷ (piece length × width ÷ 144); pallets = sq ft ÷ pallet coverage.
  • calc_pool_salt Pounds and bags of pool salt to raise a saltwater pool from its current salt level to the target your chlorine generator needs. Formula: Salt (lb) = gallons × 8.34 lb/gal × (target ppm − current ppm) ÷ 1,000,000. Bags = ⌈lb ÷ bag size⌉.
  • calc_pool_chlorine Fluid ounces of liquid chlorine (sodium hypochlorite) to raise free chlorine by a target number of ppm, from pool volume and product strength. Formula: Available chlorine (g) = gallons × 3.78541 L/gal × ppm (mg/L) ÷ 1,000. Product (mL) = grams ÷ (strength% ÷ 100), since trade percent is grams of ava
  • calc_appliance_energy_cost Daily and yearly kWh and the cost to run any appliance from its wattage, hours of use and your electricity rate. Formula: kWh per day = watts × hours ÷ 1,000; kWh per year = kWh per day × days; cost = kWh × rate.
