About Home Calculators

Our home improvement calculators help DIYers and homeowners plan projects accurately. Nothing's worse than running out of paint mid-wall or buying too many boxes of flooring. Get your quantities right the first time.

These calculators account for real-world factors like waste percentages, coverage rates, and installation patterns. Whether you're painting a room, laying flooring, or spreading mulch, you'll know exactly what to buy.

DIY Pro Tips

  • Paint Coverage: One gallon covers ~350-400 sq ft per coat on smooth walls, less on textured
  • Flooring Waste: Add 10% for straight patterns, 15% for diagonal, 20-25% for herringbone
  • Mulch Depth: 2-3 inches is ideal - too deep can suffocate plants and harbor pests
  • Electricity Costs: Space heaters and AC units are often the biggest power draws in a home
