How to Estimate Painting Cost

Painting cost depends on three components: paint, materials, and labor. Whether you're DIY or hiring a contractor, understanding each cost component helps you budget accurately and compare quotes.

Component 1: Paint Cost

Paint is typically priced per gallon. Contractor-grade interior paint costs $20-35 per gallon; premium brands (Sherwin-Williams, Benjamin Moore) cost $45-80 per gallon. Calculate the number of gallons needed using the Paint Calculator, then multiply by the price per gallon.

Example: 2 gallons × $50/gal = $100 in paint.

Component 2: Materials

Beyond paint, you'll need:

  • Primer (if needed): $20-40 per gallon
  • Roller covers: $3-8 each (1 per room)
  • Brushes: $5-15 each (2-3 needed)
  • Painter's tape: $5-8 per roll
  • Drop cloths: $10-25 each
  • Paint tray and liners: $5-15

Materials typically add $40-80 to a single-room project.

Component 3: Labor (If Hiring a Contractor)

Professional painters typically charge by the square foot of wall area:

  • Interior walls: $1.50-3.50 per sq ft (includes paint + labor)
  • Exterior walls: $2.00-4.50 per sq ft
  • Ceilings: $1.00-2.50 per sq ft (additional)
  • Trim/doors: $1.00-3.00 per linear ft

For a 12 × 10 room with 8 ft ceilings (301 sq ft paintable), expect $450-1,050 for labor + materials if hiring a pro.

DIY vs Hiring a Pro

DIY painting a single room costs $100-180 in materials (paint + supplies). Hiring a professional costs $300-600 per room. The break-even is usually 2-3 rooms — if you're painting the whole house, professional labor is often competitive with DIY when you factor in your time.

Getting Accurate Quotes

When requesting quotes from contractors:

  • Measure your rooms beforehand using the Wall Paint Calculator
  • Specify the paint brand and quality you want
  • Ask if primer is included
  • Ask if trim and ceiling are included or extra
  • Get at least 3 written quotes — prices vary significantly

Prices vary by location, season, and contractor availability. Use the Painting Cost Estimator to enter your local prices and get a customized estimate.
