Quick Answer: Exterior paint commonly runs $40 to $90 per gallon as of 2026 for a quality pro grade, with budget builder lines at $30 to $45 and premium elastomeric and acrylic lines at $80 to $120. Primer adds $30 to $70 per gallon. Your real price moves with paint grade, resin chemistry, sheen, color depth, substrate, volume, and the titanium dioxide commodity index, so use these ranges as a starting point and pull current quotes for the bid date.
What Drives the Price of Exterior Paint
Exterior paint is pigments, binders, resins, and additives in water based acrylic, latex, or oil based form. It carries more resin and mildewcide than interior paint because it must survive UV, moisture, and temperature swings. The cost per gallon moves with grade, chemistry, sheen, and freight, and understanding each helps you bid accurately.
- Paint grade: Builder grade exterior runs $30 to $45 per gallon for basic coverage on clean substrates. Pro grade, the workhorse for residential repaint, sits at $40 to $70. Premium lines from Benjamin Moore Aura, Sherwin Williams Emerald, and Duration sit at $70 to $110. Elastomeric coatings for stucco and masonry run $80 to $120 per gallon and stretch to bridge hairline cracks.
- Resin chemistry: 100 percent acrylic is the standard for adhesion and color hold, and it sits in the middle of the range. Vinyl acrylic is cheaper and used in builder grade. Silicone enhanced and alkyd modified acrylics run $10 to $30 higher per gallon but last longer on hard substrates.
- Sheen: Flat is standard for siding and stucco because it hides surface variation. Satin and low lustre add $3 to $8 per gallon and shed water better. Semi gloss for trim, doors, and shutters runs $5 to $12 higher per gallon. Do not use flat on trim, it holds dirt.
- Color depth: Whites and pastels sit at the low end. Mid tones add $3 to $6 per gallon. Deep base and dark accent colors need more pigment and tint, adding $6 to $15 per gallon. Custom matched colors at the pro desk may carry a tint fee of $3 to $8 per gallon.
- Substrate and primer: Bare wood, new stucco, fiber cement, and metals need specific primers. Bonding primer runs $40 to $65 per gallon. Masonry primer and alkali resistant primer run $35 to $55. Stain blocking primer for cedar and redwood bleed runs $45 to $70.
- Volume: Single gallon retail carries the highest markup. Five gallon buckets drop the per gallon price 8 to 15 percent. Contractor accounts get 10 to 25 percent off list and rebates of 2 to 5 percent on annual spend.
- Region and brand: Sherwin Williams, Benjamin Moore, PPG, and Kelly Moore dominate the pro channel. Coastal markets with salt air and UV demand higher grades, and prices run 10 to 20 percent above inland markets for the same product.
- Commodity index: Titanium dioxide is the main white pigment and a traded commodity. When TiO2 rises, white and light exterior paint prices follow within a quarter. Acrylic resin and mildewcide costs also move the base price.
Typical Price Ranges by Grade
Use these ranges for residential and light commercial exteriors as of 2026. They assume pro grade paint bought at a pro paint store on a contractor account, not single gallon retail.
- Builder grade exterior flat: $30 to $45 per gallon. New construction siding, clean substrates, short warranty.
- Pro grade 100 percent acrylic: $40 to $70 per gallon. The default for residential repaint and most substrates.
- Pro grade satin or low lustre: $45 to $80 per gallon. Siding and trim that needs water shedding.
- Pro grade semi gloss: $55 to $90 per gallon. Trim, doors, shutters, and high wear surfaces.
- Premium acrylic lines: $70 to $110 per gallon. Benjamin Moore Aura, Sherwin Williams Emerald, Duration.
- Elastomeric coating: $80 to $120 per gallon. For stucco, masonry, and bridging hairline cracks.
- Direct to metal enamel: $50 to $95 per gallon. For railings, doors, and metal siding.
- Bonding primer: $40 to $65 per gallon. For glossy, chalky, or hard to bond surfaces.
- Stain blocking primer: $45 to $70 per gallon. For cedar, redwood, and tannin bleed.
For a 2,000 SF two story house with a 2,500 SF exterior wall area, figure two coats at 300 SF per gallon. That is 8 to 10 gallons per coat, doubled for two coats, plus 3 to 4 gallons of primer. Budget $650 to $1,400 in paint alone before primer, caulk, masking, and labor.
How to Calculate the Quantity You Need
Gallons equals paintable square footage divided by coverage. Most pro grade exterior paints cover 250 to 350 SF per gallon on smooth siding, less on rough stucco or textured surfaces. Figure 200 to 250 SF per gallon on rougher textures. Deduct openings over 4 SF, then double the single coat figure for two coats, which is standard on exteriors.
Add a 10 percent waste factor for roller loading, spray loss, cut in waste, and touch up. Round up to the next five gallon bucket or full gallon. A tighter 8 percent waste factor is realistic on simple elevations with a spray rig, but bump to 12 to 15 percent on jobs with deep colors, heavy texture, or a lot of cut in around windows and trim.
Tie each paint quantity to the takeoff by elevation, sheen, and color. A single job often mixes flat on body siding, satin on stucco, and semi gloss on trim. Do not lump them into one line or you lose the ability to value engineer later.
How to Buy Smarter
- Open a contractor account at two pro paint stores. Accounts get 10 to 25 percent off list, tinting, and rebates of 2 to 5 percent on annual spend.
- Buy in five gallon buckets when you need more than two gallons of a color. They drop the per gallon cost 8 to 15 percent.
- Get three quotes on the same grade and sheen. Pro paint prices vary 10 to 30 percent between stores in the same market.
- Lock quotes for 30 to 60 days on long bids. Titanium dioxide and acrylic prices move, and a stale quote is a guess on a six week job.
- Use the right primer for the substrate. Bonding primer on glossy paint, masonry primer on new stucco, stain blocker on cedar. The right primer saves a third coat of finish.
- Match sheen to the substrate. Flat on siding hides variation. Satin or low lustre on stucco sheds water. Semi gloss on trim, doors, and shutters for durability.
- Control waste. A tight lid on each can, spray rig calibration, and tracking touch up cuts bucket count by 8 to 12 percent. Spray loss runs 15 to 25 percent without backrolling and proper tip sizing.
Where Estimators Get It Wrong
The most common mistake is bidding one paint price for the entire job. Body, trim, doors, and shutters use different grades and sheens, and the per gallon cost moves 30 to 50 percent between them. Price each line separately or the bid misses the real cost.
Another error is forgetting primer on bare or changed substrates. Bare wood, new stucco, and fiber cement all need a primer coat, and at $40 to $70 per gallon it adds real money on a 2,500 SF job. If you assume self priming paint covers like a real primer, you will either underbuy or apply three coats.
Do not ignore the coverage hit on texture and rough siding. A rough stucco or cedar shake wall drops coverage from 350 SF per gallon to 200 SF per gallon, and that 40 percent gap is how estimators run out of paint on day two. Always price textured exteriors at the lower coverage.
Do not forget caulk, masking, drop cloths, and scaffold rental. Caulk runs $5 to $10 per tube for quality elastomeric. Masking and surface prep labor is often 30 to 50 percent of the total exterior paint job cost. If you bid only paint, the line item misses half the work.
Finally, do not use single gallon retail pricing for a pro bid. A $70 single gallon at a home center is not your cost on a 30 gallon order through a contractor account. Pro stores discount volume heavily and stock the grades and tint you actually need.
Putting It Together
Exterior paint is a commodity with a wide price range that moves with grade, resin chemistry, sheen, color, substrate, and the TiO2 index. For a defensible bid, price each grade and sheen separately, add primer as its own line, and add a realistic waste factor for texture and spray loss. Refresh your quotes for the bid date, get three supplier prices, and run a contractor account for the load pricing and rebates. The per gallon number matters, but the grade mix, coverage assumption, and prep labor often move the job cost more than the unit price.
