How to Price a Painting Job: A Contractor's Pricing Formula

Ask ten painters how they price jobs and you'll get ten different answers. Some charge per square foot. Some give a flat day rate. Some just look at the wall and "feel out" a number.

The painters who consistently make money have one thing in common: they use a real formula. Not a magic one. Not a secret. Just an honest accounting of what the job actually costs, plus the margin they need to stay in business.

This post walks through that formula, gives you realistic numbers for 2026, and runs two worked examples (one interior, one exterior) so you can see exactly how the math plays out. By the end, you'll be able to price any painting job in 15 minutes and know your number is defensible.

The painting job pricing formula

Here it is, stripped down. Every other pricing approach is just a shortcut version of this:

That's it. Five inputs. The trick isn't knowing the formula, it's getting each input right. Most painters underprice because they forget overhead, skip the contingency, or don't actually charge a profit margin (they think their hourly rate already includes it, but it doesn't).

Let's break each one down.

1. Labor cost

Labor is the biggest line item on most painting jobs and the easiest to underestimate. The math:

Labor cost = (Estimated hours) × (Your hourly rate)

How to estimate hours

For interior work, painters typically cover 100 to 150 square feet of wall per hour, including cutting in, two coats, and minor prep. For exterior, drop to 75 to 100 square feet per hour because of weather, ladders, prep work, and overspray protection.

If you've got a 12 ft × 14 ft bedroom (8 ft ceilings), the wall area is roughly:

• Two long walls: 2 × (14 × 8) = 224 sq ft
• Two short walls: 2 × (12 × 8) = 192 sq ft
• Subtract doors and windows: roughly -40 sq ft
• Total wall area: ~376 sq ft

At 125 sq ft per hour, that's about 3 hours of painting. Add 30 minutes for setup and cleanup, and you're at 3.5 labor hours for one bedroom, two coats.

What hourly rate should you charge?

This is the question that trips up most painters. There's a difference between what you pay yourself and what you charge the client. They're not the same.

In 2026, residential painting labor rates in the US generally fall in these ranges:

If you're newer or competing on price, start at the low end. If you have a portfolio, reviews, and a 2-3 week backlog, you should be at the high end. Charging too little is the single biggest mistake new painters make. If your phone is constantly ringing with new leads who all say yes, your prices are too low.

2. Materials

Materials are easier to estimate because the math is concrete. The basics:

• 1 gallon of paint covers approximately 350 sq ft in one coat. Most jobs need two coats, so you're really covering ~175 sq ft per gallon.
• Primer covers similar amounts but is usually only one coat.
• Paint cost in 2026: Mid-grade interior is $40-$60/gallon, premium (Sherwin-Williams Emerald, Benjamin Moore Aura) is $75-$100/gallon. Exterior premium runs $55-$90/gallon.

For our 376 sq ft bedroom example:

• 376 sq ft ÷ 175 sq ft per gallon (two coats) = ~2.2 gallons. Round up to 3 to be safe.
• 3 gallons × $55/gallon = $165 in paint
• Add primer (1 gallon × $40) = $40
• Supplies: rollers, brushes, drop cloths, tape, plastic = ~$35
• Total materials: ~$240

The materials markup question

Should you mark up materials? Yes. Most painters add 15-25% on top of materials cost. Here's why: you're driving to the paint store, picking up the materials, hauling them to the job, and dealing with returns when something's wrong. That's labor too, but it's hidden inside the material line. The markup compensates you.

$240 materials × 1.20 markup = $288 charged to client

3. Overhead

Overhead is the cost of being in business that doesn't show up on any one job. Insurance. Vehicle. Phone. Marketing. Tools. The accountant. Office supplies. The fact that you can't bill 40 hours a week because some days are quoting, driving, or paperwork.

Most solo painters undercount overhead by half. A realistic accounting:

Pick a realistic number for your business. If you're a solo painter with one truck doing $80k a year, your overhead is probably around $14k annually, or 17.5% of revenue.

To bake overhead into your quote, multiply your subtotal (labor + materials) by your overhead percentage. Or, simpler, build it into your hourly rate by raising it 15-20%.

4. Profit margin

Here's the part painters forget. Your hourly rate covers what you pay yourself. Overhead covers what it costs to run the business. Profit margin is what's left for you to grow, save, or weather a slow month.

Without profit, you're just making a wage. The business itself isn't earning anything.

Healthy profit margins for painting:

• Solo painter: 15-25% profit margin on every job
• Small crew (2-4 painters): 20-30%
• Established business (5+): 25-40%

If you're not pulling at least 15% net profit on your jobs, you're working a paid hobby, not running a business.

5. Contingency

Every painting job has unknowns. The wall has a hairline crack you didn't see. The ceiling needs an extra coat. The trim is sealed with oil-based and you didn't bring shellac. The client decides they want one wall in a different color.

Add 10-15% contingency on every quote to cover surprises. If you don't use it, that's bonus margin. If you do, you're not eating the cost.

For high-prep or older homes (anything pre-1978 or with obvious damage), bump contingency to 20%. The unknowns multiply on those jobs.

Worked example 1: Interior bedroom repaint

Let's run the formula on the 12 × 14 bedroom from earlier. Walls only, two coats, light prep, mid-grade paint.

Round up to $800. That's a solid quote for a single interior bedroom repaint in 2026, assuming a mid-tier solo painter in a mid-size US market. Higher in metros, lower in rural areas.

For comparison, lots of painters would walk this room and say "$400" off the top of their head. They'd lose money on it once you account for the drive, the paint store run, and the 4 hours actually spent on site.

Worked example 2: Exterior siding repaint

Now a tougher one. A 1,800 sq ft single-story ranch home, vinyl siding, 5 years since last paint. Light pressure wash needed, minor caulking, two coats premium exterior paint.

Round to $5,250. Industry surveys show the average exterior repaint on a single-story home runs $4,000-$7,000 in 2026, so this number is comfortably mid-range. A premium painter in a major metro could charge $7,500+ for the same job.

The square-foot pricing shortcut (and when to use it)

After you've done 50-100 jobs, you can shortcut the formula by pricing per square foot. Most painters in 2026 land somewhere in these ranges:

The square-foot shortcut works because you've already absorbed the formula into your gut after enough reps. Don't use it before you've run the full formula 50 times. If you skip the math early, you'll just memorize bad numbers.

Common pricing mistakes painters make

Some patterns that show up over and over with painters who lose money:

• Pricing off the client's budget instead of the job. If they say "I have $2,000 to spend," that has nothing to do with what the job actually costs. Quote the real number.
• Not charging for the first paint store run. That's an hour of your time, gas, and your truck. Bill it.
• Forgetting drive time. If the job is 30 minutes away each way, that's an hour off your billable day.
• Quoting "around $X" verbally and never writing it up. The number always lands lower than your real estimate would have.
• Eating change orders. "While you're here, can you do the hallway too?" is a separate quote, not a freebie.
• Underestimating prep. Prep usually takes longer than the painting itself. Old houses, water damage, cabinets, anything with caulk. Triple your gut estimate for prep on tough jobs.

How to know if your pricing is working

Your pricing is right if all three of these are true:

• You win roughly 40-60% of the quotes you send. Higher than 70% means you're too cheap. Lower than 30% means you're too expensive (or your sales process is broken).
• You're booked 2-4 weeks out. No backlog means low prices. Too long a backlog (8+ weeks) means you're losing customers to competitors.
• Your net profit per job is at least 15%. Track this on every job. If it's slipping below 15%, raise prices.

If two of those three are off, your pricing isn't the problem; your sales or your costs are. If all three are off, you need a price increase. Today.

The bottom line

Pricing a painting job isn't art. It's accounting wrapped in a quote. Five inputs, run them honestly, add a buffer, send it.

The painters who do this consistently make money. The ones who guess, wing it, or chase the client's budget number burn out within five years. There's no third option.

Run this formula on your next ten jobs and track how it compares to what you would have charged off the cuff. The gap will probably surprise you.
