You're staring at that scuffed, "builder-beige" wall and thinking it’s time for a change. Maybe a moody forest green or a crisp, gallery white. But then you start Googling. One site says it’s $200. Another says $1,200. The gap is wide enough to drive a truck through, and honestly, it’s frustrating.
Calculating the cost for painting a room isn't just about multiplying length by width. It’s about the "hidden" stuff. The cracks in the plaster you didn't notice. The fact that you chose a deep navy blue that requires three coats instead of two. Or the realization that your ceilings are ten feet high, not eight.
Let's get real. If you’re hiring a pro in 2026, you aren't just paying for paint. You're paying for their insurance, their gas, and the thirty years of experience that keeps them from getting paint on your expensive hardwood floors. If you're doing it yourself, you're paying in weekend hours and probably a few ibuprofen.
The Raw Numbers: What are you actually looking at?
For a standard 10x12 bedroom, most homeowners land somewhere between $400 and $950 for a professional job. That's the sweet spot. If someone quotes you $150 to paint a whole room, run. Seriously. They’re either using watered-down contractor grade paint or they aren't insured.
Labor is the giant in the room. It usually accounts for about 70% to 80% of your total bill. Professional painters typically charge between $50 and $100 per hour per person. A small bathroom might take one person four hours. A large living room with vaulted ceilings? That’s a two-person, two-day job.
Why the square footage lies to you
Total floor space is a terrible metric for paint. You paint walls, not floors. A 120-square-foot room has roughly 350 to 400 square feet of wall space once you account for windows and doors.
But wait.

Are you doing the baseboards? The crown molding? The closet?
Painting a closet can add $75 to $150 easily because it’s cramped, annoying, and requires a lot of cutting in. If you want the ceiling done—and you probably should, because "old" white looks yellow next to "new" white—tack on another $150 to $250.
The Paint Can Paradox
Don't buy the cheapest paint at the big-box store. Just don't.
High-quality acrylic latex paint, like Sherwin-Williams Emerald or Benjamin Moore Regal Select, costs between $70 and $100 per gallon. It sounds steep. However, the pigment density is higher. This means you use less paint to cover the old color. Cheap $25-a-gallon paint often requires three or four coats to cover a dark wall. You end up buying more cans and spending twice as much time working.
Pro Tip: Look at the Volume Solids on the technical data sheet. Higher volume solids usually mean a more durable finish and better "hide" (the ability to cover what's underneath).
The "Prep" Tax
Prep is where the real money is made or lost.

If your walls are perfect, the painter walks in, masks the floor, and starts rolling. But most walls aren't perfect. You have nail pops. You have that weird texture from a 1970s DIY project. You have grease in the kitchen.
Professional painters spend more time with sandpaper and caulk than they do with a brush. If your walls need significant drywall repair or "skim coating" to make them smooth, the cost for painting a room can double instantly. According to the Painting Contractors Association (PCA), prep work is the most underestimated variable in any residential bid.
DIY vs. Professional: The Honest Trade-off
DIY is "free" if you don't value your time.
You'll need:
- Brushes ($20 each for good ones like Wooster or Purdy)
- Rollers and frames ($30)
- Drop cloths (canvas is better than plastic; $40)
- Painter's tape ($10 a roll)
- The paint itself ($150-$200 for a room)
Total DIY outlay is usually around $250 to $350 for the first room. Subsequent rooms get cheaper because you already have the tools.
But here’s the rub. A pro can paint a bedroom in five hours and it looks flawless. A DIYer usually spends all of Saturday moving furniture and prepping, all of Sunday painting, and Monday morning realizing they missed a spot behind the radiator.

Regional Price Swings are Huge
Where you live matters more than the color you pick.
In high-cost areas like New York City, San Francisco, or Chicago, labor rates are astronomical. You might pay $1,200 for a room that would cost $500 in rural Ohio. This isn't just "greed." It’s the cost of doing business—parking permits, higher insurance premiums, and the general headache of hauling gear into a high-rise.
Surprising Factors That Jack Up the Price
- The "Furniture" Factor: If the painter has to move your heavy oak dresser and your king-sized bed, they will charge you for it. Clear the room yourself to save $50-$100.
- Color Transitions: Going from black to white? That’s a primer coat plus two top coats. Going from light grey to slightly darker grey? You might get away with one heavy coat if the painter is skilled.
- Trim Complexity: Flat baseboards are easy. Elaborate, multi-piece Victorian crown molding is a nightmare. Detailed trim work can sometimes cost as much as the walls themselves because it requires a steady hand and a tiny brush.
- Lead Paint: If your home was built before 1978, there’s a chance of lead-based paint. If a pro detects it, they have to follow EPA RRP (Renovation, Repair, and Painting) protocols. This involves specialized HEPA vacuums, plastic sheeting, and certification. It adds hundreds to the bill.
How to Get a Fair Quote
Don't just take the first number. Get three.
But when you compare them, look at the details. Does Quote A include two coats or one? Does Quote B include the ceiling? Is Quote C using "Contractor Grade" paint?
The best painters will give you a "scope of work." It’s a written document that says exactly what they will do. If they just scribble "$600" on a business card, keep looking. You want someone who mentions "sanding between coats" or "caulking gaps in the trim." That’s the sign of a craftsman, not just a guy with a bucket.
Actionable Steps for Your Painting Project
- Measure your wall area accurately. Multiply the perimeter of the room by the ceiling height, then subtract about 20 square feet for each door and 15 square feet for each window. This gives you the real number for paint estimation.
- Pick your sheen wisely. Flat paint hides bumps but is hard to clean. Eggshell or satin is the standard for living areas. Semi-gloss is for bathrooms and trim because it stands up to moisture and scrubbing.
- Test your colors. Buy those $5 sample pots. Paint a 2x2 square on different walls. Look at it at 10:00 AM, 4:00 PM, and 9:00 PM under artificial light. The color will change drastically.
- Clear the decks. If you’re hiring out, move the small stuff, take down the curtains, and pull the furniture to the center of the room. The easier you make it for the crew to start, the more likely they are to stick to their timeline.
- Check references for "cleanliness." Anyone can put paint on a wall. Very few can leave a house without leaving a single drop of paint on the carpet or a dust film on the furniture. Ask specifically how they protect your belongings.
The cost for painting a room is ultimately an investment in how you feel in your space. Whether you're doing it to sell or just to stop hating your hallway, knowing the numbers upfront prevents the "renovation sticker shock" that ruins the excitement of a fresh start. Pay for quality paint, be honest about the state of your walls, and don't skimp on the prep work. Your future self, standing in a perfectly finished room, will thank you.
