How Much Does It Cost to Paint the Interior of a House? [2026 Data]

In 2026, the national average cost to paint the interior of a house is $2,022, based on 65,117 verified projects reported by Angi Pros. Most homeowners pay between $965 and $3,089, with the spread driven primarily by home size, paint type, and your location. The biggest factor is square footage, as labor typically runs $2 to $6 per square foot.

Interior Painting Cost Factors: What Affects the Price?

Several key factors shape the final cost of painting your home's interior, and understanding them helps you build a realistic budget before reaching out to a pro.

Square Footage of Home

Home size is the primary driver of interior painting costs, with the national average running $2.75 per square foot for walls alone and $4.70 per square foot when walls, trim, and ceilings are included. Having your home's square footage ready before speaking with a pro will help you get the most accurate quote possible. The table below breaks down the average cost of interior painting based on square footage:

Paint Surfaces 

Painting costs vary by surface type, and knowing what each surface typically costs helps you budget accurately across walls, ceilings, trim, and baseboards. Adding an accent wall increases your room budget by 20% to 30% to cover additional paint, materials, and the extra taping and drying time required, so the cost to paint an accent wall will run higher than a standard matching wall. The table below breaks down the average cost to paint various interior surfaces:

Paint Type

Paint costs $15 to $40 per gallon, depending on the brand and paint finish, and specialty options like long-lasting, high-gloss, stain-blocking, or mold-resistant formulas sit at the higher end of that range. See how paint type affects your total interior painting cost in the table below:

Ceiling Height

Ceiling height directly impacts interior painting costs: standard 8-foot walls are the most affordable, while taller walls—especially under cathedral ceilings—require scaffolding and safety gear, driving labor rates beyond just the cost of extra paint.

Labor

Labor makes up between 75% and 95% of the total cost of a professional interior painting project. You can reduce that portion of your bill by patching and prepping your walls before the pros arrive, so they can move straight to painting.

Surface Preparation

Wall prep costs $0.50 to $0.75 per square foot for sanding and patching, and this work is essential for a smooth, flawless finish. Some contractors bundle prep into their standard charges, but drywall repair costs add an average of $600 to your budget depending on severity. Paint primer is another prep expense to plan for, especially when painting a light color over a dark one, and runs about $10 per quart while covering roughly 100 square feet per coat, though some walls may require multiple coats of primer.

Wall Repairs

If your walls are a bit worse for wear, you may need to do some repairs to provide a clean slate for painting. Scratches, dents, and water stains are common issues you can tackle with spackle and a putty knife. Again, taking on this task yourself can save money over having your painter do the work.

Texturing

Textured walls hide paint flaws and add depth to a space, but they can increase your painting budget by up to 50% because textured surfaces often require double the amount of paint compared to smooth walls. Before hiring a professional painter, confirm that they offer this specialized service.

Wallpaper Removal

Removing wallpaper costs around $3 per square foot, which works out to about $535 in a standard 12-by-12-foot room.

Popcorn Ceiling Removal

Popcorn ceiling removal costs $1 to $2 per square foot, and once the ceiling is cleared, additional expenses for texture, painting, or other refinishing options will add to the final total. Contact a popcorn ceiling removal pro near you for an accurate estimate on your specific project.

Unique Architectural Features

Unique architectural features like archways or columns add to your interior painting cost primarily through labor, since the complexity of these areas demands more time and attention to detail than standard flat surfaces.

Moving Furniture

The last thing you want is to get paint on your furniture, so you’ll want to move your beautiful velvet couch either to the center of the room (covered) or out of the room completely. To reduce labor costs when hiring a painter, move the furniture (if you can safely lift it!) before they get started. 

Location

Where you live affects what you pay to paint your home's interior, since the majority of painting costs go toward labor and rates adjust to reflect the local cost of living.

Interior Painting Cost by Square Footage: How Does Size Affect Costs?

Measuring the square footage of each room you plan to paint is an essential part of the process. To calculate square footage, multiply the length of the room by the width in feet:

Length x Width = Area in square feet.

If the space isn't a perfect shape, section off the room to make squares or rectangles and measure each section at a time. Add the square footage areas together to get the total square footage of the room.

As a general rule of thumb to know how much paint you need, 1 gallon of paint is required per 300 to 400 square feet. If you have textured walls or choose thinner paint formulas, your project may require more materials.

To err on the side of caution, overestimate by purchasing 1 gallon per 300 square feet. To get a general estimate, use this equation:

Total square footage / 400 = Number of gallons of paint.

For example, if your house is 2,400 square feet, you would need 6 gallons of paint (2,400 / 400 = 6).

Interior Painting Additional Costs: What Should You Budget For?

While budgeting for an interior paint refresh, consider these add-on services that can maximize the impact and increase home value even further.

• Cost to replace light fixtures: $150–$1,000

• Cost to install crown molding: $600–$2,100

• Cost to refinish wood flooring: $1,100–$2,700

• Cost to replace interior doors: $360–$1,200

• Cost to replace windows: $3,400–$11,700

• Cost to replace kitchen cabinets: $2,000–$11,000

How to Save Money While Painting a Home’s Interior

Whether you decide to DIY your interior painting or hire a professional painter, you can use the tips below to reduce your overall costs.

• Do the prep work yourself. Save on setup and cleanup by tarping off furniture and fixtures and taping off the area ahead of time.

• Carry out drywall repair if possible. Reduce the time painters spend on repairs by fixing holes or scratches in the walls before they arrive.

• Paint trim and ceilings at the same time. You’ll spend more up front for these added services, but you’ll save overall since the painters will already be on-site for your walls.

• Buy the materials yourself. Some painters might mark up materials, especially if they need to take a special trip to buy them. Purchase materials yourself instead to save a bit of money.

• Be discerning about what you paint. Sometimes, it makes sense to paint the entire interior of your home, but you can also hire a pro to tackle only the main areas to get the biggest bang for your buck. You can then tackle the bedrooms that guests won’t see on your own.

Why You Should Hire an Interior Paint Pro

Hiring a local painter costs more upfront, but you benefit from faster results, a flawless finish, and less risk of damage to walls or furnishings. Pros bring specialized tools and experience, making the process smoother and often saving you money on touch-ups or repairs.

Here’s why it’s ideal to hire an interior paint pro

Painting the interior of a house is a detailed project that requires skill and expertise. Here are some of the top reasons to work with a pro:

• Interior painters ensure walls, trim, baseboards, and fixtures aren’t damaged during painting.

• They have the brushes, rollers, sprayers, and techniques needed for a smooth, even coat on a variety of surfaces.

• Working with a pro ensures your project is completed efficiently, accurately, and with a professional-quality finish.

• Bundling painting with wall repairs, priming, or finishing work can save on overall labor and material costs.

If you want to DIY some painting tasks

If you want to take on parts of the project yourself, here are a few DIY tasks that can help save time and labor costs:

• Move furniture away from walls and cover it with drop cloths to protect from paint splatters.

• Remove outlet covers, light switch plates, and any wall-mounted décor before painting begins.

• Patch small holes or cracks in walls so the painter can achieve a smooth finish more efficiently.
