How Much Does It Cost to Paint a House Interior?

$1,500 to $4,000 is the average cost to paint a house interior for a typical home with 1,500 to 2,500 square feet of living space. Most homeowners pay around $2,500 for a full interior repaint with mid-range paint and standard prep work. Per room, expect to spend $200 to $800 depending on size, paint quality, and how much surface preparation the walls need.

Interior painting is one of the most popular home improvement projects, and homeowners frequently ask how much it costs to paint a house interior before getting started. A fresh coat of paint can make an outdated space feel new again, and it pairs well with other upgrades like popcorn ceiling removal ($1 to $3 per square foot) if you are updating an older home.

Interior Painting Cost per Room

$200 to $1,500 is the typical range for these services. Here is the full breakdown.

Room Size	Walls Only	Walls + Ceiling	Walls, Ceiling + Trim
Small (bedroom, bathroom)	$200 - $400	$300 - $500	$400 - $650
Medium (living room, dining room)	$350 - $600	$450 - $700	$550 - $900
Large (great room, open plan)	$600 - $1,000	$750 - $1,200	$900 - $1,500

These ranges assume two coats of paint and basic prep (light cleaning, taping, and minor touch-ups). High ceilings, accent walls with multiple colors, or specialty finishes will push costs toward the higher end.

Factors That Affect Interior Painting Cost

$1,500 to $4,000 is the typical range, and several key factors determine where your project falls within it.

Number and Size of Rooms

The cost of interior painting depends mainly on room count. Painters price by room or by square foot of paintable surface. A small bedroom has roughly 300 to 400 square feet of wall space, while a large open-plan living area can have 800 to 1,200 square feet of wall space. More rooms mean more paint, more labor hours, and more masking and prep time.

Paint Quality

Paint quality has a significant effect on both cost and longevity. Basic contractor-grade paint costs $15 to $25 per gallon and is adequate for rentals or quick refreshes. Mid-range name-brand paint (Benjamin Moore, Sherwin-Williams) runs $30 to $50 per gallon and provides better coverage, durability, and color accuracy. Premium and designer paints cost $50 to $100+ per gallon and offer superior washability, low-VOC formulas, and specialized finishes. A gallon covers about 350 to 400 square feet, so a medium-sized room typically needs 2 to 3 gallons for two coats.

Scope of Work

Painting walls only is the most affordable option. Adding ceilings increases the cost by 25 to 40% because ceiling work requires more drop cloths, overhead labor, and careful cutting along edges. Including trim, baseboards, door frames, and crown molding adds another 15 to 25% on top of that. Trim painting is detailed, slow work that requires steady hands and usually a separate type of paint (semi-gloss or high-gloss).

Prep Work Required

Surface preparation is where costs can climb quickly. Walls in good condition need only light sanding, spot priming, and cleaning. Walls with nail holes, minor cracks, or scuff marks need patching and sanding, which adds $50 to $150 per room. Extensive prep work like wallpaper removal, skim coating over textured surfaces, or repairing water damage can add 40 to 60% to the total project cost. If your hardwood floors need attention at the same time, hardwood floor refinishing ($3 to $8 per square foot) is commonly done alongside a repaint for a complete room transformation.

Ceiling Height

Standard 8-foot ceilings are priced at base rates. Rooms with 9 or 10-foot ceilings cost 10 to 15% more, and rooms with vaulted or cathedral ceilings (12 feet or higher) can cost 25 to 50% more due to the need for scaffolding or tall ladders and the added safety considerations.

Interior Painting Cost by Paint Quality

$15 to $1,200 is the typical range for these services. Here is the full breakdown.

Paint Grade	Cost per Gallon	Cost per Room (labor + materials)	Best For
Basic (contractor grade)	$15 - $25	$200 - $500	Rentals, flips, quick refreshes
Mid-range (name brand)	$30 - $50	$350 - $700	Most homeowners, good value
Premium (designer/specialty)	$50 - $100+	$500 - $1,200	High-end homes, specialty finishes

DIY vs. Professional Interior Painting

$100 to $300 per room for DIY versus $200 to $800 per room with a professional is the core trade-off when deciding whether to paint yourself. Understanding how much interior painting costs helps you decide between DIY and hiring a pro, and there are real trade-offs. DIY materials (paint, primer, rollers, brushes, tape, drop cloths) save you 60 to 70% compared to hiring a professional, but a single room can take an entire weekend for someone without experience.

Professional painters charge $200 to $800 per room (labor and materials included) and can typically finish a standard bedroom in 4 to 6 hours. They deliver cleaner lines, handle all the prep work, and move much faster than a weekend DIYer. For a whole-house repaint, hiring professionals saves you weeks of work and delivers a more polished result.

Where DIY makes the most sense: a single accent wall, a small bathroom, or a kid's bedroom where perfection is not the goal. Where hiring a pro makes sense: whole-house repaints, rooms with high ceilings, trim and detail work, or anytime the prep work involves wallpaper removal or significant repairs. If you are painting as part of a home addition ($80 to $200 per square foot), the contractor typically includes painting in the build price.

How to Save Money on Interior Painting

$250 to $1,000 in potential savings is achievable with the right approach. These tips can help reduce your total cost.

Get at least 3 quotes from licensed painters. Prices vary widely even within the same city.
Do the prep work yourself. Moving furniture, removing outlet covers, and filling nail holes saves the painter time and reduces your bill.
Choose one color for multiple rooms. Fewer color changes mean less time cleaning brushes, switching paint, and taping off edges.
Paint during the off-season. Late fall and winter are slower months for painters, and you may find better rates or faster scheduling. Pairing a fresh paint job with chair reupholstery ($200 to $1,500) gives a room a completely refreshed look without buying all new furniture.
Buy paint during sales. Major brands run holiday sales (Memorial Day, Labor Day, Black Friday) offering 30 to 40% off retail prices.
Skip the ceiling if it is in good shape. Ceiling painting adds 25 to 40% to the cost, and many ceilings look fine with just a fresh coat on the walls.

Frequently Asked Questions

How much does it cost to paint a house interior?

Painting the interior of a house costs $1,500 to $4,000 for an average-sized home (1,500 to 2,500 square feet). That breaks down to roughly $2 to $6 per square foot of wall space, depending on paint quality, number of coats, ceiling height, and the amount of prep work required. A single room costs $200 to $800 on average.

How much do painters charge per room?

Professional painters charge $200 to $800 per room depending on size. A small bedroom or bathroom costs $200 to $400, a medium living room costs $400 to $700, and a large great room or open-plan space costs $800 to $1,500. These prices include two coats of paint and basic prep but not extensive repairs or wallpaper removal.

Is it cheaper to paint yourself or hire a painter?

DIY painting saves 60 to 70% on labor but takes significantly longer. Painting a room yourself costs $100 to $300 in materials, while hiring a pro costs $300 to $800 for the same room. For one or two simple rooms, DIY makes sense. For a whole-house project, hiring professionals is usually worth the investment.

How long does it take to paint a room?

A professional painter can complete a standard bedroom in 4 to 6 hours, including prep, two coats, and cleanup. A DIY painter should budget a full day or weekend for the same room. A full interior paint job on a 2,000-square-foot home takes a professional crew 3 to 5 days.

How often should you repaint interior walls?

Interior walls should be repainted every 5 to 10 years depending on the room. High-traffic areas like hallways, kitchens, and kids' rooms may need repainting every 3 to 5 years. Bedrooms and formal living rooms can go 7 to 10 years between paint jobs. Using higher-quality, washable paint extends the time between repaints.
