The wall was patched but the homeowner thought I missed it. Three coats of paint and you’d never know there used to be a 4-inch hole there. She asked me how I knew to charge for the patching when other contractors had quoted her without it. The answer is simple. I write paint estimates that show every line item, so the client sees the work and the other guy looks like he’s hiding something.
That’s what a real paint estimate does. It’s not just a number at the bottom. It’s a contract that protects you from change orders, sells the work, and makes the cheap bid look like exactly what it is.

Quick Answer
A paint estimate breaks a paint job into labor, paint, primer, prep work, trim, and sundries. Interior repaints run $1.50 to $5 per square foot of wall area. Exterior runs $2 to $7 per square foot. A complete estimate lists square footage, paint brand and quantity, prep scope, number of coats, color count, and a fixed price. Verbal quotes lose jobs. Itemized estimates win them.
What Belongs on Every Paint Estimate
A clean paint estimate has eight line items. Every job. No exceptions.
- Wall square footage measured, not guessed
- Paint brand, type, and gallons (with sheen and coats)
- Primer gallons if needed
- Prep work scope (patching, sanding, caulking, masking)
- Trim, doors, and closets as separate lines
- Number of color changes
- Sundries (tape, drops, brushes, rollers, plastic)
- Total labor hours at your rate
When all eight show up on the page, the client can compare your bid to the other guy’s and see exactly what they’re paying for. When two of those are missing, the homeowner thinks you’re more expensive. You’re not. The other contractor is just lying by omission.
How to Write a Paint Estimate Step by Step
This is the process I run on every paint job, in order. Skip a step and you’ll lose money.
1. Measure the wall square footage
Add up length × height for every wall. Subtract doors (21 sq ft each) and standard windows (15 sq ft each). For ceilings, multiply length × width. A 12 × 14 bedroom with 8-foot ceilings has roughly 416 sq ft of wall area before openings.
2. Calculate paint quantity
A gallon of paint covers 350 sq ft for one coat. Most jobs need two coats, so double it. For 1,800 sq ft of walls, you need 6 gallons for two coats, plus 1 gallon for touch-up. Use the Paint Calculator to nail this without doing the math by hand.
3. Pick the paint tier
Match the paint to the client’s budget and the room. Builder-grade for rentals. Premium for kitchens, bathrooms, and high-traffic areas where washability matters.
| Paint Tier | Cost per Gallon | Coverage | When to Use |
|---|---|---|---|
| Economy | $20 - $35 | 350 sq ft | Rentals, garages, closets |
| Standard | $30 - $55 | 350 sq ft | Most interior walls |
| Premium | $45 - $85 | 350 sq ft | Kitchens, baths, trim, owner-occupied |

4. Price the labor
Interior painting labor runs $1 to $4 per square foot of wall area. Exterior runs $1.50 to $5. Cabinet refinishing runs $50 to $120 per linear foot of cabinetry. Source: BLS painter wages (47-2141) median $48,660/year and Angi 2026 painting cost data.
If you charge by the hour, a solo painter covers 150 to 200 sq ft of wall per hour at the brush and roller. Spray work runs 3x faster but the prep and masking eat the savings.
5. Add prep and trim as separate lines
Patching a hole isn’t free. Sanding old gloss isn’t free. Caulking 80 feet of trim isn’t free. Put each on its own line with hours. When the cheap bid doesn’t have these and yours does, you’re not the expensive one. You’re the honest one.
6. Apply markup and overhead
Most painters run 25% to 35% gross margin on paint jobs. Use the Contractor Markup Calculator to convert your cost into a sell price. Don’t forget overhead. Insurance, truck, phone, software all need to be covered before profit shows up.
Worked Example: 1,800 Sq Ft Interior Repaint
This is a real-world layout: 3-bedroom, 2-bath, 1,500 sq ft single-story. Walls only, two coats, standard paint, light prep.
| Line Item | Quantity | Rate | Cost |
|---|---|---|---|
| Wall labor | 1,800 sq ft | $2/sf | $3,600 |
| Standard paint | 6 gallons | $40 | $240 |
| Primer (kitchen, bath) | 3 gallons | $25 | $75 |
| Prep work | 4 hours | $80/hr | $320 |
| Patch and sand (5 spots) | 2 hours | $80/hr | $160 |
| Trim and door touch-up | 1 day | $500 | $500 |
| Sundries | flat | flat | $150 |
| Subtotal | $5,045 | ||
| Markup (25%) | $1,261 | ||
| Estimate total | $6,306 |
Job sells at roughly $3.50 per square foot of wall area. Right in the middle of the $3 to $5 range Angi lists for full-service interior repaints in 2026.
Worked Example: Single Bedroom, Walls Only
Different scope, same logic. Bedroom is 12 × 14 with 8-foot ceilings, two windows, one door. Wall area after openings: roughly 380 sq ft.
| Line Item | Quantity | Rate | Cost |
|---|---|---|---|
| Wall labor | 380 sq ft | $2/sf | $760 |
| Standard paint | 2 gallons | $40 | $80 |
| Prep (light patch, 1 hour) | 1 hour | $80/hr | $80 |
| Sundries | flat | flat | $40 |
| Subtotal | $960 | ||
| Markup (25%) | $240 | ||
| Estimate total | $1,200 |
That’s about $3.16 per square foot of wall, which lines up with what most painters charge for a one-room job in 2026.
Regional Pricing: What City Multipliers Do to Your Estimate
Painter wages and material costs vary by metro. The same 1,800 sq ft interior repaint runs very different numbers depending on where the house sits. These multipliers come from BLS regional wage data for painters (47-2141) and RSMeans city cost indexes.
| Metro | Adjustment vs National Average | Example: $6,300 Job Becomes |
|---|---|---|
| New York, NY | +35% | $8,505 |
| San Francisco, CA | +30% | $8,190 |
| Seattle, WA | +18% | $7,434 |
| Chicago, IL | +8% | $6,804 |
| Atlanta, GA | -5% | $5,985 |
| Phoenix, AZ | -10% | $5,670 |
| Houston, TX | -12% | $5,544 |
Note: pricing varies by region, project complexity, paint quality, and access to the work area. Always price per local labor rates and material costs.
What Most Contractors Get Wrong on Paint Estimates
I see the same mistakes on competing bids when homeowners share them with me. These are the ones that kill profit.
- Underestimating prep. Old gloss has to be sanded. Holes have to be patched. Caulk lines fail in 5 years and need to be cut out and redone. Don’t bury this in “labor.” Put it on the page.
- One coat pricing. A gallon doesn’t cover in one coat unless you’re going darker over similar tone. Two coats is the standard, three for white over dark.
- Skipping the primer line. Drywall patches need primer. New drywall needs primer. Bathroom and kitchen ceilings often need stain-blocking primer. Don’t forget to charge for it.
- No trim breakout. Trim is slower than wall painting. A door takes 30 to 45 minutes brushed properly. Charge per door and per linear foot of trim, not as a flat add-on.
- Verbal quotes. “About four grand” loses to a written estimate every time, even if the written estimate is higher. Homeowners want a piece of paper they can compare and forward to their spouse.
- No color change line. Going from beige to navy is two extra coats minimum. From beige to white is a primer plus two coats. This isn’t free time and shouldn’t be free dollars.
How to Make Your Paint Estimate Look Professional
The estimate format matters as much as the price. Here’s what a winning paint estimate looks like on the page.
- Header with your logo, license number, and contact info. Looks legit before they read a number.
- Project address and date. Pulls the estimate out of the inbox pile.
- Scope summary in two sentences. “Repaint all interior walls, ceilings, and trim. Two coats premium paint, light prep, walls only.”
- Itemized table. Every line from the eight-item list above.
- Inclusions and exclusions. What’s covered. What isn’t (furniture moving, drywall repair beyond patch, exterior). This single section kills change-order fights.
- Payment terms. Deposit percentage, milestone payments, final on completion.
- Signature line. When they sign, you’ve got a contract.
A handwritten estimate on a notepad costs you 30% of the jobs you’d otherwise win. I’ve watched it happen.
FAQ
How much should I charge for a paint estimate?
Don’t charge for the estimate itself in residential. Most painters give free estimates to win the work. Commercial paint estimates sometimes carry a fee for detailed takeoffs, but that’s the exception.
How long should a paint estimate take to produce?
A walkthrough takes 30 to 60 minutes. The written estimate should take 15 to 30 minutes after you’re back at the truck. If it takes longer, your process needs work, or you should be using software. EstimationPro turns notes and photos into a complete itemized estimate in under 5 minutes.
What’s a fair markup on paint and materials?
Most painters mark up materials 20% to 35%. Labor is usually marked up to cover overhead and profit, typically a 25% to 35% gross margin overall. Source: NAHB builder cost data and RSMeans O&P benchmarks.
Should I quote per square foot or per room?
Both. Per square foot for wall area gives you the math. Per room is what the client understands. List both on the estimate. Most pros calculate per square foot internally and present per-room totals to the homeowner.
How long is a paint estimate good for?
30 days is standard. Paint prices and labor rates change, especially with primer and premium paint trending up year over year. Always include an expiration date on the estimate.
Do I need to include a regional disclaimer?
Yes. One sentence at the bottom: “Pricing reflects current 2026 rates and may change due to material cost fluctuations or scope changes.” Protects you from price changes between estimate and start date.
What I’d Tell a Painter Just Starting Out
Build your estimate template once and use it on every job. Eight line items, every time. Premium paint at the top of your bid. Cheap paint as the optional alternate. Markup baked in, not tacked on.
The reason most painting businesses fail isn’t the painting. It’s the estimating. Bid too low and you lose money on the job. Bid too high without explaining why and you lose the job. A clear, itemized paint estimate solves both. It shows you know your numbers, it justifies your price, and it makes the lowball guy look sketchy by comparison.
Contractors using EstimationPro report 4 to 6 hours saved per week on paint estimates compared to spreadsheet methods, and they win more bids because the estimates go out the same day instead of three days later. Speed wins paint jobs. Detail closes them.
Try EstimationPro free and stop losing paint jobs to slow quotes. EstimationPro doesn’t just build the estimate. It sends the proposal automatically, follows up with the homeowner on a schedule you set, and turns the signed estimate into an invoice when the job is done. That’s how you win more of the bids you already send.
