How much will the project actually cost? Total = paint + labor + supplies. DIY interior runs $0.50–1.50/sq ft for materials only. Hiring a contractor pushes that to $2–4/sq ft interior and $1.50–3.50/sq ft exterior, including labor.

HOW IT WORKS
DIY vs. hire breakdown
DIY costs are mostly paint and a few hundred dollars in supplies. Hiring a contractor adds labor, which is ~70% of the total bill. The break-even consideration: a typical 12 × 14 bedroom takes a homeowner 2 weekends ($0 labor) and ~$200 in materials, vs. a contractor at $800–1,200 total. The pro will be faster and cleaner; you save 75% by doing it yourself.
Per-square-foot benchmarks
Interior DIY: $0.50–1.50/sq ft of wall area
Interior hired: $2–4/sq ft of wall area
Exterior DIY: $0.75–1.75/sq ft of wall area
Exterior hired: $1.50–3.50/sq ft of wall area
Cabinet DIY: $50–100 per linear foot
Cabinet hired: $100–250 per linear foot
Where contractors save money
Pros buy paint at trade-account discounts (~30% off retail), spray instead of brush (4× the speed on exteriors), and have prep down to a science (saving hours per room). They also know when to charge for repairs separately so the paint quote isn't padded.
Why quotes swing by region
The same bedroom can cost twice as much depending on your zip code. Labor is the lever. In high-cost metros like San Francisco, Boston, or Seattle, a painter's day rate reflects rent and demand, so a $1,000 job in Tulsa can hit $2,000 on the coast. Paint barely moves with geography — a gallon ofSherwin-Williams or Benjamin Moore costs about the same anywhere. When you compare online averages to your own quotes, adjust for your market first, or you'll think every local painter is overcharging when they're simply local.
What actually drives a quote up
Painters don't price walls, they price problems. Heavy prep is the big one: patching cracks, sanding glossy trim, scraping peeling exterior, or skim-coating damaged drywall can add hours before a drop of paint goes on. Height and access matter too — stairwells, two-story foyers, and cathedral ceilings need scaffolding or ladders, which slows everyone down. Detailed trim, crown molding, and multiple colors each add cut-in time. Lead paint in pre-1978 homes triggers certified containment. Ask any bidder to itemize prep separately so you can see what's paint and what's repair.
Getting and comparing three quotes
Always get three written estimates, and make sure they cover the same scope or the numbers are meaningless. One painter may quote two coats and full prep while another assumes one coat and you patching the walls. Ask each for the number of coats, the paint brand and line, whether prep and primer are included, and how trim and ceilings are counted. The cheapest bid often skips coats or buys budget paint. The middle bid with clear scope usually wins. Get the brand and sheen in writing so nobody substitutes a thinner product later.
Frequently asked questions
How much does it cost to paint a room?+
A standard 12-by-14 bedroom runs about $200 in materials as a DIY job, or roughly $800 to $1,200 hiring a pro. Most of the pro price is labor, not paint.
What is the cost per square foot to paint a house interior?+
Professional interior painting averages about $2 to $6 per square foot of wall, including two coats and basic prep. DIY materials alone are closer to $0.50 to $1.50 per square foot.
How much do painters charge per hour?+
Most painters charge $25 to $75 per hour depending on region, with a national average near $50. Coastal cities run higher; the South and Midwest run lower.
What percentage of a paint job is labor?+
Labor is typically 70 to 85 percent of a professional painting bill. That is why a premium paint that costs more per gallon barely moves the total when you hire it out.
Is it cheaper to paint myself or hire a pro?+
DIY saves roughly 70 to 80 percent because you skip labor, but it costs you weekends and a learning curve. A pro is faster, cleaner, and buys paint at a trade discount.
Why does premium paint sometimes cost less overall?+
Premium paint has more binder, so it covers more area per gallon and lasts longer. Better hide can mean one fewer coat, and a 15-year exterior film beats repainting a cheap one every 5 to 7 years.
What hidden costs should I expect in a paint quote?+
The usual surprises are wall repairs found after furniture moves, primer on patches or bare spots, extra coats for deep colors, and moving or covering heavy furniture. Exterior jobs add power washing and caulking. Ask whether prep, primer, and a second coat are already in the number, since these are the line items painters most often leave out to look cheaper.
Does the room type change the price?+
Yes. Kitchens and bathrooms cost more per square foot because of cabinets, tile cut-ins, and moisture-rated paint. Stairwells and entryways carry a height premium for ladders. Bedrooms are the cheapest, mostly flat walls. Trim-heavy rooms with wainscoting or built-ins take longer than the square footage suggests, so two same-size rooms can quote very differently.
When does DIY actually save money?+
DIY pays off on simple, low rooms with sound walls and one easy color, where you are really just buying paint and a weekend. It stops saving when the job needs tall ladders, heavy patching, spray equipment, or many coats of a tricky color. At that point a pro's speed, trade paint discount, and clean lines often beat the true cost of your time and mistakes.
