Exterior Paint Cost Per Gallon: 2026 Price Guide
How Much Does Exterior Paint Cost Per Gallon in 2026?
The exterior paint cost per gallon in 2026 typically runs $30 to $80 for standard acrylic latex exterior paint. Budget contractor-grade lines sit at $25–$40 per gallon, mid-range paints (the sweet spot for most homes) run $40–$60, and premium lines like Sherwin-Williams Duration or Benjamin Moore Aura Exterior cost $50–$80 per gallon. Prices kept climbing this year — JD Power’s 2026 U.S. Paint Satisfaction Study found exterior paint prices rose an average of $3.22 per gallon, the largest increase of any paint segment. A typical whole-house exterior needs 5 to 25 gallons depending on home size, siding texture, and number of coats.
Quick-answer table (typical 2026 prices):
| Paint tier | Per gallon | Per 5-gallon bucket | Best for |
|---|---|---|---|
| Budget / contractor-grade | $25–$40 | $110–$175 | Rentals, fences, sheds, outbuildings |
| Mid-range (100% acrylic) | $40–$60 | $150–$225 | Most homes — the best value |
| Premium (top-tier resins) | $50–$80 | $200–$300 | Harsh sun, coastal air, long repaint cycles |
| Elastomeric / masonry specialty | $45–$70 | $175–$275 | Stucco and masonry with hairline cracks |
Primer, needed for bare wood, bare masonry, or dramatic color changes, runs $15–$40 per gallon — always cheaper than paying for an extra finish coat.
Exterior Paint Cost by Brand (2026 Typical Prices)
Brand and product line is the single biggest driver of per-gallon price. These are typical shelf prices at major retailers; regional variation and sale pricing apply:
| Brand / product line | Quality tier | Per gallon | Coverage per gallon |
|---|---|---|---|
| BEHR Premium Plus Exterior | Mid-range | $38–$48 | 250–400 sq ft |
| BEHR Marquee Exterior | Upper-mid | $52–$62 | 250–400 sq ft |
| Valspar Duramax Exterior | Mid-range | $38–$50 | 250–400 sq ft |
| Sherwin-Williams SuperPaint Exterior | Mid-range | $55–$68 | 350–400 sq ft |
| Sherwin-Williams Duration Exterior | Premium | $68–$85 | 300–400 sq ft |
| Benjamin Moore Regal Select Exterior | Upper-mid | $58–$72 | 400–450 sq ft |
| Benjamin Moore Aura Exterior | Premium | $70–$85 | 400–450 sq ft |
| Glidden / store contractor lines | Budget | $25–$35 | 250–350 sq ft |
Worth noting: in that same 2026 JD Power study, BEHR ranked highest in exterior paint satisfaction (739/1,000), followed by Sherwin-Williams (722) and Benjamin Moore (720) — the mid-priced winner beating the premium brands on value perception. Holiday sales at big-box retailers routinely cut these prices 20–30%, so timing a purchase around Memorial Day or Labor Day is one of the easiest ways to save.

How Many Gallons Do You Need? Coverage Math
Exterior paint covers roughly 250–400 square feet per gallon per coat — smooth vinyl siding lands near 400, rough stucco or textured brick drops toward 250. Nearly every exterior needs two finish coats for proper protection and uniform color.
| Home size | Paintable surface (approx.) | Gallons for 2 coats | Paint cost at $45/gal |
|---|---|---|---|
| 1,000 sq ft, 1 story | 1,200–1,600 sq ft | 6–10 | $270–$450 |
| 1,500 sq ft | 1,800–2,400 sq ft | 9–14 | $405–$630 |
| 2,000 sq ft, 2 story | 2,200–3,000 sq ft | 11–18 | $495–$810 |
| 2,500 sq ft | 2,800–3,800 | 14–22 | $630–$990 |
| 3,000 sq ft | 3,400–4,600 | 17–28 | $765–$1,260 |
The formula: measure each wall’s length × height, subtract large windows and doors (don’t bother subtracting small ones — the waste factor covers it), divide by 350 for smooth siding or 250 for rough surfaces, then multiply by 2 coats. Always round up and buy 10% extra — running out mid-wall with a custom-tinted color is a costly mistake.
Why Exterior Paint Costs More Than Interior Paint
Exterior paint runs about $10–$20 more per gallon than comparable interior paint, and the premium is earned:
- UV blockers that keep color from chalking and fading in direct sun
- Mildewcides and fungicides that resist mold in humid climates
- Thicker film build — exterior coatings go on heavier to bridge hairline cracks
- Flexibility — the resin system expands and contracts with temperature swings without cracking
- Fade-resistant pigments — deeper, more lightfast colorants cost more to manufacture
Interior paint skips all of this, which is why it’s cheaper — and why using interior paint outside is a guaranteed early failure. For the interior side of the math, see our guide to interior house painting cost per square foot.
Cost Drivers: What Moves the Per-Gallon Price
- Resin quality. 100% acrylic resins (mid-range and up) adhere better and last years longer than vinyl-acrylic blends found in budget paint. This is the main thing you’re paying for.
- Finish. Flat/matte is cheapest; satin and semi-gloss run a few dollars more per gallon but shed water and dirt better — worth it for trim and doors.
- Color depth. Deep bases (navy, forest green, brick red) need far more colorant than white or pastel bases — expect $5–$10 more per gallon for dark colors, and sometimes an extra coat.
- VOC formulation. Low- and zero-VOC exterior paints cost slightly more but matter less outdoors than in; standard low-VOC is fine for most exteriors.
- Container size. Five-gallon buckets cut the per-gallon price 10–20% versus single gallons — the single biggest lever on unit price.
- Region and retailer. The same gallon can vary $10+ between markets; contractor supply stores and seasonal sales beat everyday big-box pricing.
5-Gallon Buckets: The Math on Buying Big
If your project needs more than 4–5 gallons, the 5-gallon bucket almost always wins:
| Buy | Typical price | Effective per gallon | Savings |
|---|---|---|---|
| 5 × 1-gallon cans (mid-range) | 5 × $48 = $240 | $48.00 | — |
| 1 × 5-gallon bucket (same line) | $200 | $40.00 | ~17% |
| 5 × 1-gallon cans (premium) | 5 × $75 = $375 | $75.00 | — |
| 1 × 5-gallon bucket (same line) | $310 | $62.00 | ~17% |
One caution: only buy the bucket if you’ll use it. Tinted paint is generally non-returnable, and a half-used bucket of custom color has almost no resale value. Confirm your gallon estimate before committing.
DIY vs. Professional: Paint Cost in Context
Paint itself is a surprisingly small slice of a professional job — which changes the buy-vs-supply calculation:
| Factor | DIY (you buy the paint) | Professional job |
|---|---|---|
| Paint per gallon | $25–$80 retail | Often 10–20% less via contractor accounts |
| Total paint for a 2,000 sq ft home | $500–$1,200 | Included in the $2,500–$10,000+ project price |
| Labor | Your weekends (5–10 days) | $1.50–$4 per sq ft of surface |
| Equipment | Sprayer rental $75–$150/day, ladders, masking | Included |
| Warranty on the finish | None — and some pros won’t warranty customer-supplied paint | 2–5 years typical |
The takeaway: paint is roughly 15–25% of a professional exterior job. Saving $200 on cheaper paint while paying $5,000 in labor is false economy — this is exactly where the mid-range or premium gallon earns its keep. Run the full numbers in our house painting cost calculator.
Money-Saving Tips
- Buy 5-gallon buckets for the body color — instant 10–20% per-gallon savings on any whole-house job.
- Shop the holiday sales. Memorial Day, July 4th, and Labor Day routinely bring 20–30% off top brands.
- Don’t go below ~$30/gallon for the house body. A $35/gallon paint lasting 6 years costs more per year than a $65/gallon paint lasting 12. Do the per-year math, not the per-gallon math.
- One-coat claims still need two coats on bare surfaces, repairs, or color changes — budget for it upfront.
- Keep the color close to the existing one. Similar shades cover in two coats; dramatic changes need primer plus two, which is 25–40% more paint.
- Save leftovers properly. A sealed, properly stored gallon keeps 2–5 years for touch-ups — label it with the room, color formula, and date.
- Pre-1978 homes: factor EPA lead-safe (RRP) requirements into the project, not just the paint budget — see the EPA’s lead-safe renovation rules.
Frequently Asked Questions
How much does a gallon of exterior paint cost in 2026?
$30–$80 per gallon for standard acrylic latex exterior paint. Budget lines run $25–$40, mid-range 100% acrylic paints run $40–$60, and premium lines run $50–$80. Exterior paint prices rose about $3.22/gallon on average in 2026.
How many square feet does a gallon of exterior paint cover?
250–400 square feet per gallon per coat. Smooth vinyl or aluminum siding covers near 400; rough stucco, textured brick, or weathered wood drops toward 250. Plan for two coats on nearly every exterior.
Is expensive exterior paint worth it?
Usually yes, on the per-year math. A $65/gallon premium paint lasting 12 years costs about $5.40 per year per gallon; a $35/gallon budget paint lasting 6 years costs $5.80 per year per gallon — and you pay for the labor of repainting twice. Premium pays off most on harsh sun, coastal, or freeze-thaw exposures.
How much paint do I need for a 2,000 sq ft house exterior?
Plan 12–20 gallons for two coats, depending on stories and siding texture — roughly $540–$900 in mid-range paint. Measure wall-by-wall and add 10% waste rather than guessing from floor square footage.
Can I use interior paint on the outside of my house?
No. Interior paint lacks UV blockers, mildewcides, and the flexible resin system exterior paint needs — it will chalk, peel, and fail within a year or two outdoors, voiding any savings many times over.
The Bottom Line
Budget $30–$80 per gallon for exterior paint in 2026, with $40–$60 mid-range 100% acrylic the sweet spot for most homes. Buy it in 5-gallon buckets, shop a holiday sale, and remember the real math is cost per year of service — not cost per gallon. The most expensive paint job is the one you have to redo early because the cheap paint failed.
Prices are typical 2026 US retail ranges gathered from major retailers and industry pricing data; your actual cost depends on brand, region, color depth, and sale timing. Always measure carefully and buy 10% extra — custom-tinted paint is rarely returnable.
