Tools for the project in front of you.
Calculate materials, waste, purchase quantities and optional costs. Every tool includes its method, assumptions, a worked example and clear planning limits.
Paint & Finishing
2 calculatorsPlan coatings and wall finishes from the surfaces being covered, not from room size alone. Coverage rate, coats, pattern repeat and package size can all change the shopping quantity.
Use the actual product label whenever possible, especially for paint coverage and wallpaper roll dimensions.Floors & Walls
5 calculatorsTurn room dimensions into tiles, flooring packs, drywall sheets, grout and trim. The key planning step is separating theoretical area from waste-adjusted and package-rounded purchase quantities.
Layout complexity, openings, offcuts and stock lengths can make two projects with the same area use different amounts of material.Tile Calculator
Calculate tiles, waste allowance, boxes and estimated cost.
Flooring Calculator
Estimate flooring area, packs, waste and project cost.
Drywall / Plasterboard Calculator
Estimate sheets and supporting materials for walls and ceilings.
Grout Calculator
Estimate grout from tile size, joint width and project area.
Baseboard / Skirting Calculator
Estimate linear length, pieces, waste and cost.
Construction
5 calculatorsEstimate concrete, masonry, roofing, siding and insulation quantities using transparent geometry and product-specific coverage inputs.
These tools estimate material quantity only. Structural adequacy, code compliance, reinforcement and building-envelope design require separate project decisions.Concrete Calculator
Estimate concrete volume, ready-mix quantities or bag counts.
Brick / Block Calculator
Estimate masonry units, mortar allowance, waste and cost.
Roofing Materials Calculator
Estimate roof covering quantities and material allowance.
Siding Calculator
Estimate siding coverage, panels and waste allowance.
Insulation Calculator
Estimate insulation area, packs and project quantities.
Outdoor
6 calculatorsPlan landscaping and exterior projects using area, depth, spacing and linear measurements. Gravel, mulch, soil, pavers, fencing and decking all convert dimensions into different purchase units.
Ground conditions, drainage, compaction, foundations and structural framing are outside a simple quantity estimate and may require additional planning.Gravel Calculator
Calculate gravel volume, bags, bulk quantity, estimated weight and cost.
Mulch Calculator
Estimate mulch volume, bag or bulk quantities and optional cost.
Garden Soil Calculator
Estimate soil volume for beds, planters and landscaping.
Paver / Patio Calculator
Estimate pavers, waste, packs, base material and project cost.
Fence Calculator
Estimate panels, posts, rails and project materials.
Decking Calculator
Estimate deck boards, spacing, waste, purchased length and material cost.
Energy
2 calculatorsEstimate a room AC capacity starting point and model appliance running costs from power, usage and your own electricity rate.
Energy and HVAC results are scenario estimates. Whole-building load calculations, electrical suitability and tariffs with complex charging structures need more detailed assessment.No calculator found

PlanCalq publishes calculation logic, assumptions, worked examples and limitations alongside the calculators. Product labels and local project requirements still take precedence where they provide more specific information.
