Planning estimators for paint, flooring, tile, concrete, and landscaping materials.
Available Home & Construction Tools
Paint Calculator
Estimate exact paint volume required for interior walls and ceilings, factoring in standard door and window deductions and multiple coats.
Flooring Calculator
Determine total square footage and material box quantities required for hardwood, luxury vinyl plank (LVP), laminate, or carpet projects.
Tile Calculator
Calculate exact tile piece counts and square footage for bathroom floors, kitchen backsplashes, and walk-in showers with customizable waste allowances.
Concrete Calculator
Calculate concrete volume in cubic feet and cubic yards, and determine premix bag quantities for slabs, footings, and patios.
Mulch Calculator
Estimate bulk cubic yards and bagged quantities of bark mulch, wood chips, or garden soil based on bed dimensions and layer depth.

How Much Paint Do I Need? A Practical Guide
Calculate exact paint requirements for any room: wall surface area, deductions for doors and windows, coats needed, and coverage per gallon.
How to Calculate Flooring Needed for a Room
Master flooring estimation: room square footage, cutting waste percentages, plank box rounding, and allowances for complex layouts.
Material Estimation & Waste Factor Guidelines
- Always budget a 10% waste buffer for standard room flooring and tile layouts, increasing to 15% for diagonal installations or irregular floor plans.
- When measuring wall areas for paint, subtract 20 square feet per standard interior door and 15 square feet per standard window.
- Order bagged concrete and mulch by total volume rounded up to the nearest whole bag or cubic half-yard to avoid mid-project shortfalls.
