One gallon of semi-gloss white paint typically costs $25-$75, with an average near $45 for a standard interior acrylic latex product. Brand, durability, interior or exterior formulation, and whether the price includes professional application are the biggest differences; a painter’s labor can cost more than the paint itself.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| One gallon, paint only | $25 | $45 | $75 | Standard interior retail range |
| Premium or specialty gallon | $55 | $80 | $110 | Higher durability or specialty formula |
| One gallon with professional application | $125 | $250 | $450 | Small-job minimums affect the total |
| Coverage per gallon | 250 sq. ft. | 350 sq. ft. | 400 sq. ft. | One coat on a smooth, primed surface |
What one gallon of semi-gloss white paint usually costs
For paint alone, budget $25-$75 for a common one-gallon can. Economy interior paint often falls near $25-$35, midrange washable acrylic latex is generally $35-$55, and premium scrubbable or stain-resistant products commonly run $55-$85. Specialty exterior or kitchen-and-bath formulas can reach $110, depending on brand and retailer.
A realistic average is about $45 per gallon before tax, primer, tools, or labor. One gallon usually covers roughly 300-400 square feet per coat on a smooth surface; textured, porous, or unprimed walls may bring coverage closer to 250-300 square feet. Assumptions: U.S. retail pricing, standard white tint, one gallon, and normal store availability.
How paint, prep supplies, and labor shape the quote
A small paint-only purchase has few cost components, but a complete painting quote includes surface preparation and application. For a one-gallon touch-up or small room, labor minimums can dominate. A contractor may charge for travel, setup, masking, and cleanup even when the paint quantity is low.
| Quote component | Typical price | What changes the charge | Common unit |
|---|---|---|---|
| Paint | $25-$75 | Brand, formula, and grade | Per gallon |
| Primer | $20-$50 | Stains, bare drywall, or color change | Per gallon |
| Prep supplies | $10-$40 | Tape, drop cloth, patching, and sanding | Per small job |
| Painter labor | $35-$75 | Local rates and surface condition | Per hour |
| Small-job minimum | $125-$300 | Setup and travel for limited work | Per visit |
Paint may be less than one-quarter of a small professional job’s total. For labor estimates, a basic calculation is . Confirm whether the quote includes paint, primer, patching, and cleanup.
Sheen, durability, and formula can shift the gallon price
Semi-gloss reflects more light than eggshell or flat paint and is often selected for trim, doors, bathrooms, and areas that need frequent cleaning. The sheen alone does not set a fixed price: product grade and intended use matter more. A basic interior formula may cost $25-$45, while a washable premium interior option may cost $50-$85.
Exterior semi-gloss paint is formulated for weather exposure and often costs $40-$90 per gallon. Low-VOC, mildew-resistant, or kitchen-and-bath products can add roughly $5-$20 compared with a basic interior gallon. Custom-tinted whites may also have a different shelf price than untinted white, though some stores do not charge extra for standard tinting.
Check the label for the surface and location rather than choosing by sheen alone. Using interior paint outdoors or the wrong product on trim can lead to early peeling and repainting expense.
How much area will a gallon cover in one coat?
Manufacturers commonly list coverage around 350-400 square feet per gallon under ideal conditions. For budgeting, use 300-350 square feet per coat on typical walls, and less for rough plaster, masonry, heavy texture, or a surface that absorbs paint. Two coats double the paint requirement, though the second coat may spread farther over a sealed surface.
A 10-by-12-foot room with 8-foot ceilings has about 350 square feet of wall area before subtracting doors and windows. One gallon may cover one coat, but two coats usually require around two gallons after allowing for waste and touch-ups. Trim, cabinets, and doors use additional paint because of their edges and repeated coats.
Measure paintable surface area and count coats before buying. A spare quart or leftover paint can be useful for repairs, but buying several gallons without checking coverage risks excess.
Regional store prices vary by roughly 5% to 15%
Prices are not identical nationwide. Large metropolitan areas and high-cost coastal markets may run about 5%-15% above national retail averages, particularly for premium brands. Smaller markets can be near the average or lower when local competition is strong. Sales, contractor accounts, and store promotions can matter more than region for a single gallon.
Sales tax adds to the checkout price and differs by state and locality. Delivery charges may apply to online orders, while pickup is often free. Compare the same product line, finish, and can size; a sale price for a lower-grade gallon is not a direct comparison with a premium washable formula.
Compare identical product specifications and include tax or delivery in the total. For a one-gallon purchase, a modest price difference may be outweighed by a promotion or the cost of a separate trip.
Painter labor and small-job minimums matter most
Professional painting labor commonly runs $35-$75 per hour, but many contractors price by the project rather than by the gallon. A simple, prepared accent wall might take 2-4 hours including setup and cleanup; door or trim work can take longer because it requires careful masking and multiple coats. A small-job minimum of $125-$300 is common.
Painting a single wall can therefore cost $125-$350 for labor and materials, even when the paint itself is under $75. A larger room or multi-room project spreads setup time across more area and may be priced per square foot instead. Ask whether the quote includes sanding, caulking, patching, and moving or protecting furniture.
For one gallon of paint, confirm the contractor’s minimum charge before scheduling. Labor estimate: 2-4 hours at $35-$75 per hour, plus any stated minimum or prep fee.
Extra coats, primer, and disposal add to the purchase
Primer may be unnecessary when repainting a clean, similar-color surface in good condition. Bare drywall, repaired areas, stains, or a strong color change can require primer, adding about $20-$50 per gallon. Stain-blocking products can cost more. Allow another $10-$40 for basic tape, sanding materials, patch compound, and drop protection if those supplies are not already on hand.
Most household paint purchases do not include a separate disposal fee, but local rules may restrict liquid paint disposal. Unopened returns depend on store policy, and tinted paint may not be returnable. Keep the receipt and check the retailer’s return terms before buying a custom color or extra cans.
Include primer only when the surface condition calls for it, not automatically. Proper prep can prevent buying additional coats to hide stains or uneven absorption.
Spend less by matching the gallon to the job
Choose a standard interior formula for ordinary indoor walls and reserve premium scrub-resistant paint for high-traffic areas, trim, or surfaces that are cleaned often. If the job is a small repair, use leftover paint when the color and product are known; otherwise, a color match may differ slightly because the existing coating has aged.
Compare at least two quotes using the same paint grade, coat count, and prep scope. Buying during store promotions can reduce the paint bill, but avoid selecting a lower-quality formula if it requires extra coats. For an intact surface with a similar color, ask whether one coat is suitable; for bare or stained areas, keep the primer in the plan.
The most reliable savings come from buying the right quantity and avoiding unnecessary upgrades. Verify coverage on the can, measure the area, and ask the painter to identify any surface condition that would change the original estimate.
