Room Painting Cost Calculator

This calculator helps you estimate the total cost of painting a room, including paint, supplies, and optional labor costs.

How It Calculates

The calculator uses these steps to estimate your total painting cost:

1. Calculates the total wall area based on room dimensions
2. Subtracts the area of doors and windows
3. Determines the amount of paint needed based on coverage and coats
4. Calculates paint cost based on price per gallon
5. Adds essential supplies (brushes, rollers, tape, drop cloths)
6. Optionally adds labor costs if you're hiring professionals

Professional vs. DIY Costs

Professional painting typically costs $2-$6 per square foot, depending on your location, the condition of walls, and the complexity of the job. DIY painting costs about $1-$3 per square foot for materials alone.

Paint Quality Considerations

• Economy paint: $15-$30 per gallon, less durable, may require more coats
• Mid-grade paint: $30-$50 per gallon, good durability, standard coverage
• Premium paint: $50-$100+ per gallon, excellent durability, often better coverage
