Paint usually costs $20-$80 per gallon, while a professional interior painting project often runs $2-$6 per square foot of painted surface. Paint type, room size, surface preparation, labor rates, and whether the job is indoors or outdoors shape the final bill.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Interior paint | $20 per gallon | $40 per gallon | $80 per gallon | Standard to premium paint |
| Exterior paint | $30 per gallon | $50 per gallon | $90 per gallon | Weather-resistant formulas |
| DIY room repaint | $150 | $400 | $900 | Paint and basic supplies |
| Professional interior painting | $2 per sq ft | $3.50 per sq ft | $6 per sq ft | Painted wall surface; prep varies |
What homeowners pay for paint and a typical room
A gallon of interior paint generally covers about 350-400 square feet with one coat. A 12-by-12-foot room with 8-foot ceilings has roughly 400 square feet of wall area before subtracting doors and windows. Two coats usually require about 2-3 gallons, depending on coverage and color change.
For that room, DIY paint and ordinary supplies commonly total $150-$400. A painter may charge $500-$1,200 for walls, with ceilings, trim, repairs, and furniture moving potentially adding to the quote. Estimates vary with finish quality, surface condition, and local labor prices.
Assumptions: 12-by-12-foot room, 8-foot ceiling, two coats, standard paint, ordinary access.
How paint, labor, and prep appear in a quote
For a standard interior repaint, contractors may price the job as a whole or by painted surface area. The table below shows typical component ranges; some estimates combine materials, labor, and overhead rather than listing each charge separately.
| Quote component | Typical range | What it covers |
|---|---|---|
| Interior paint | $25-$70 per gallon | Common washable wall paint |
| Primer | $20-$50 per gallon | Stain blocking or color changes |
| Labor | $25-$75 per hour | Painting and routine setup |
| Surface preparation | $0.50-$2 per sq ft | Filling, sanding, and caulking |
| Supplies and protection | $30-$150 per room | Tape, covers, rollers, and brushes |
Labor and preparation can outweigh the price of the paint itself. Heavy patching, peeling coatings, furniture protection, and detailed trim work may be quoted separately or included in a higher per-square-foot rate.
Why gallon size, finish, and surface condition change price
Paint coverage and product specifications make a noticeable difference. One gallon typically covers 350-400 square feet on a smooth, primed wall, but porous or textured surfaces may need more. A color change from dark to light can also require extra coats or primer.
Standard interior paint often costs $20-$45 per gallon; premium washable or low-odor options are commonly $45-$80. Exterior paint is usually $30-$90 per gallon because it must withstand sun, moisture, and temperature changes. Semi-gloss and specialty finishes may cost more than basic flat paint.
Every additional coat can raise both material and labor charges. For a project exceeding 1,000 square feet of wall area, confirm whether the quote includes two coats, primer, and repairs. Textured walls, water stains, and peeling paint can increase prep time beyond a routine repaint.
Interior versus exterior paint budgets for a house
Interior painting generally costs $2-$6 per square foot of painted surface when professionally completed. Exterior work often runs $1.50-$5 per square foot of exterior surface, but homes with multiple stories, complex trim, or difficult access may exceed that range.
A professional interior repaint of a 1,500-square-foot home may total about $3,000-$9,000, depending on how many rooms and surfaces are included. Exterior painting for a similar-sized house often lands around $3,000-$8,000, with siding material and condition affecting the estimate.
House floor area is not the same as paintable surface area. Ask contractors to list rooms or exterior surfaces, number of coats, and included prep so estimates with different scopes can be compared fairly.
How regional labor rates shift painting estimates
Labor is usually more expensive in major coastal metros and high-cost cities than in many rural or lower-cost markets. As a broad comparison, painting quotes in high-cost urban areas may run 15%-30% above national midrange estimates, while some rural markets may be 10%-20% lower.
These differences depend on local contractor availability, insurance, travel, and project access—not just paint prices. A second-story exterior, narrow stairwell, or distant property can also require more setup time and equipment regardless of region.
Compare quotes from painters who price the same surfaces and preparation tasks. A lower bid may exclude ceilings, trim, primer, or minor repairs. Request an itemized scope and ask whether paint is included, supplied by the homeowner, or billed separately.
How long painters spend on rooms and exterior walls
A two-person crew may complete an ordinary bedroom in about 1-2 days, including routine preparation and two coats. Larger homes can take several days to a week or more; exterior jobs commonly require 3-7 days, depending on weather, access, and drying time.
At $25-$75 per labor hour, a room requiring 12-20 combined crew hours could involve $300-$1,500 in labor before materials and overhead. Contractors may use fixed project pricing instead of billing hourly, so the calculation is a way to assess the estimate, not a promised invoice.
Ask how many workers, workdays, and coats the quote assumes. Moving furniture, protecting floors, and clearing wall décor before arrival can reduce paid setup time, but substantial repairs should be discussed with the painter first.
When primer, trim, or paint removal adds charges
Primer is often needed for bare drywall, stains, patched areas, or a major color change. Expect roughly $20-$50 per gallon, plus application labor. Painting baseboards or door trim may add $1-$4 per linear foot, while doors commonly cost $50-$150 each, depending on detail and condition.
Scraping and sanding peeling exterior paint can add $0.50-$2 or more per square foot of affected area. Lead-safe work in older homes may require special procedures and higher labor charges; homeowners should confirm local requirements and contractor qualifications before work begins.
Get removal, repairs, and trim listed as separate scope items. That makes it easier to see whether an estimate includes only painting or also the work needed to make the surface ready.
Which paint and prep choices can lower the bill
Choose a paint grade appropriate to the room rather than paying for a premium formula everywhere. Durable, washable paint can make sense in kitchens, hallways, and children’s rooms, while lower-cost standard paint may be adequate for low-traffic spaces. Avoid changing colors dramatically if it will require extra coats.
Keep the job scope consistent, schedule flexible work dates, and compare at least three written estimates. Bundling nearby rooms can reduce repeated setup charges, but combining projects does not guarantee a discount. For sound walls with fading or minor scuffs, repainting may be more economical than replacing drywall or adding decorative finishes.
The clearest savings usually come from limiting unnecessary prep and upgrades without skipping needed repairs. Confirm paint brand, finish, coat count, surface preparation, cleanup, and exclusions before accepting a quote.
