Interior house painting cost calculator - quality comparison
Paint quality is one of the biggest cost factors in any interior painting project. Basic builder-grade paint costs $1.40 per square foot of wall area but typically requires more frequent repainting. Premium paint from brands like Benjamin Moore costs nearly twice as much per square foot but offers better coverage, durability and color retention, often lasting 8-10 years compared to 4-6 years for basic paint.
Frequently asked questions
How accurate is this interior painting cost estimator?
Our interior painting cost estimates are typically within 15-25% of actual contractor quotes for standard residential projects. The estimate is most useful for initial budgeting before contacting painting contractors. For a firm price, always get at least 3 quotes from licensed painters in your area.
How do I estimate interior painting costs?
To estimate interior painting costs, measure your total square footage, decide on paint quality and number of coats, then factor in ceiling work and wall prep needs. Our calculator does this automatically based on your selections. As a rule of thumb, budget $3 to $5 per square foot of floor area for a standard quality, 2-coat paint job including labor.
What is the interior paint cost calculator estimate per gallon?
A gallon of interior paint typically covers 350-400 square feet with one coat and costs $30 to $80 depending on quality. A standard 1500 sq ft home with 2 coats requires approximately 8-12 gallons of paint, representing roughly 15-20% of the total project cost, with labor making up the remaining 70-80%.
Is it cheaper to paint a house yourself or hire a professional?
DIY painting can save 60-70% on labor costs but requires significant time, proper equipment and skill to achieve professional results, particularly for ceilings, trim and color changes. For a 1500 sq ft home, DIY materials alone typically cost $400 to $800, compared to $4500 to $9000 for a fully professional job including labor.
How many coats of paint does an interior room need?
Most interior painting projects need 2 coats for proper coverage and even color, especially when changing colors significantly or covering darker existing paint. A single coat may suffice when applying the same or a very similar color, or when using high-quality paint with excellent one-coat coverage claims.
