Latex paint typically costs $20-$70 per gallon for standard interior formulas, with premium products reaching $50-$100 per gallon. Painting a typical 10-by-12-foot room often totals $300-$800 with professional labor; paint type, surface preparation, number of coats, and local labor rates drive the estimate.

| DIY 10-by-12-foot room | $100 | $200 | $350 | Paint, basic supplies, and minor prep |
| Professional room painting | $300 | $550 | $800 | Walls, two coats, standard access |
| Interior walls per square foot | $1 | $2 | $3 | Labor and materials, typical conditions |
What latex paint costs by gallon and room size
For most U.S. buyers, a gallon of interior latex paint costs $20-$70. Basic builder-grade paint is commonly $20-$35 per gallon, midrange washable paint is $35-$60, and premium or specialty formulas can cost $60-$100 or more. Exterior latex paint often runs $30-$80 per gallon, depending on weather resistance and product grade.
A gallon generally covers about 350-400 square feet on a smooth, primed surface for one coat. A 10-by-12-foot room with 8-foot ceilings has roughly 350 square feet of wall area before subtracting doors and windows; two coats may require two gallons, especially on textured or porous walls. Most room estimates assume standard latex paint, two coats, and ordinary wall preparation.
Assumptions: U.S. midrange product prices, standard 8-foot ceilings, normal access, and no major repairs.
How paint, labor, and prep appear in a quote
Professional estimates may bundle materials and labor or list them separately. The table shows typical ranges for a single 10-by-12-foot room with two coats; difficult color changes, high ceilings, or extensive patching can increase the totals.
| Quote item | Typical price | What it covers | Cost basis |
|---|---|---|---|
| Latex paint | $50-$160 | Two gallons, standard to premium | $20-$80 per gallon |
| Labor | $200-$500 | Application, cutting in, and cleanup | $25-$75 per hour |
| Prep and supplies | $30-$150 | Drop cloths, tape, light sanding, minor filling | Flat charge or hourly |
| Primer or specialty coating | $25-$100 | Stain blocking or color-change coverage | $20-$60 per gallon, plus labor |
Some contractors set a minimum charge of $250-$500, so painting one small room may cost more per square foot than a larger job. Ask whether the quote includes primer, patching, furniture protection, paint, and cleanup.
Coverage, coats, and wall condition change gallon needs
Paint quantity and labor can shift substantially with wall area and surface condition. Smooth, previously painted walls may need one coat for a close color match, while a strong color change generally calls for two coats. Bare drywall, stains, or a transition from dark to light may require primer plus two finish coats.
Textured walls can use 10%-20% more paint than smooth walls, and unpainted drywall may absorb more than the label coverage suggests. For projects above 500 square feet of wall area, even a modest coverage difference can add one or more gallons. Measure wall area and calculate coats before comparing gallon prices.
Which latex finish or quality level is worth the price?
Flat latex is often the least expensive finish and conceals small surface flaws, but it is less washable. Eggshell and satin commonly cost $2-$10 more per gallon than basic flat paint and are easier to clean in kitchens, hallways, and family rooms. Semi-gloss is frequently used for trim and moisture-prone surfaces; specialty bathroom or exterior formulas can cost $10-$30 more per gallon than entry-level paint.
Higher-priced paint may provide stronger coverage or durability, but the savings depend on the surface and use. A premium product that covers in two coats rather than three may reduce labor, while an upgrade may not pay off in a low-traffic spare room. Compare coverage claims, recommended coats, and cleanability rather than the label price alone.
How much does a painter charge for latex paint?
Professional painters commonly charge about $25-$75 per labor hour, though many bid by room or square footage. A standard room may take 5-10 hours for protection, light prep, cutting in, rolling two coats, and cleanup. High ceilings, extensive trim, occupied rooms, and drying time between coats can extend the schedule or increase the crew charge.
Labor estimates often work out to $1-$3 per square foot of wall surface for straightforward interior painting, including materials in some quotes. Confirm whether the contractor measures floor area or actual wall area; those are not interchangeable. Compare written bids with the same coat count, paint grade, and prep scope.
Three room estimates show how the total can shift
A small, smooth 10-by-10-foot bedroom may need about two gallons for two coats. DIY materials and supplies can total $100-$220; professional painting may cost $300-$600 when prep is light.
A 12-by-15-foot living room with textured walls may need three gallons and more masking. Expect roughly $150-$300 for DIY paint and supplies, or $500-$1,000 with professional labor, depending on ceiling height and furniture handling.
A 500-square-foot wall project with a dark-to-light color change may require primer and two finish coats. Materials could run $200-$450, while a contractor may quote $1,000-$2,000 if patching and additional labor are included. These examples assume ordinary access and exclude major drywall repair.
When primer, repairs, and disposal add to the bill
Minor nail-hole filling and sanding may be included, but larger cracks, water stains, peeling paint, or damaged drywall are usually extra. Basic patching can add $50-$200 per room; substantial repairs may cost several hundred dollars. Primer costs about $20-$60 per gallon, and stain-blocking products can be more expensive.
Some bids also include charges for moving furniture, removing old wallpaper, painting baseboards, or working above standard ceiling height. Ask for each item as a separate line when possible. Lead-safe preparation may be required for older homes with lead-based paint, adding specialized labor and containment costs.
Lower the latex painting price without cutting corners
Reduce cost by choosing a paint grade suited to the room, limiting unnecessary color changes, and combining nearby rooms into one project. Doing simple furniture clearing and wall washing can reduce billed prep time, but repairs or sanding should be agreed on with the painter before work starts. Buying paint in a consistent batch helps avoid shade differences and waste.
Request two or three itemized estimates that specify product brand or grade, gallons, coat count, primer, repairs, and cleanup. If the existing finish is sound, repainting may be less expensive than stripping or replacing wall coverings. Keep the scope consistent across bids so a lower price does not simply reflect fewer coats or less preparation.
