How to calculation 1 room paint cost.
Calculating the cost to paint a room involves several factors, primarily the room’s size (square footage), paint type and quality, and whether you’re hiring a professional or DIYing. A professional painter will likely charge $2-$6 per square foot, while DIY costs range from $235 to $610 for supplies alone, depending on the room size.
Sample for Excel Sheet.

Factors Influencing Cost:
- Room Size: Larger rooms require more paint and labor, increasing costs.
- Paint Quality and Type: High-quality paints offer better coverage and durability but are more expensive. Sheen (matte, eggshell, satin, etc.) also affects price.
- Number of Coats: More coats mean more paint and labor.
- Room Features: High ceilings, complex trim, and the presence of windows and doors impact the cost.
- Professional vs. DIY: Hiring a professional painter adds labor costs, while DIYing requires purchasing supplies.

Cost Breakdown:
- Professional Painting: $2-$6 per square foot (including labor and materials).
- DIY Painting Supplies: $235-$610 (depending on room size).
- Paint per Gallon: $10-$70 (depending on paint type and quality),
- Labor Costs: Can be a significant portion of the total cost, varying by location and painter.
- Additional Costs: Primer, texture painting, and specialized paint finishes can add to the overall expense.
Example:

Estimating the Cost:
- Measure the Room: Calculate the wall and ceiling area in square feet.
- Determine Paint Needs: A gallon of paint typically covers 350-400 square feet.
- Factor in Labor: For professional painting, get quotes from local painters.
- Consider Additional Costs: Primer, trim painting, and texture painting.
Example:

Example:

For a 12′ x 12′ room with 8-foot ceilings, you’d need approximately 1.5 gallons of paint for two coats according to The Spruce. If you hire a professional at $3.30 per square foot, the painting cost would be roughly $400 – $1000. If you DIY, expect to spend $235 – $610 on supplies alone.
