Painting contractors frequently underprice their work — especially when starting out — and then discover the job is barely profitable or unprofitable. Accurate pricing requires knowing your real costs: labor, materials, prep, overhead, and profit margin.
Here's how to price painting jobs correctly.
The Components of a Painting Estimate
1. Labor
Labor is typically the largest cost on a painting job. Calculate it this way:
- Estimate the time each phase takes (surface prep, priming, coats, trim)
- Multiply by your actual hourly labor cost (wages + payroll taxes + insurance, not just the wage)
- Add a buffer for unexpected prep (old paint peeling, surface repairs)
Interior painting: Many painters use square footage per painter-hour as a baseline — typically 100–150 sq ft per hour for standard interior walls, less for detailed work (trim, cabinets, high ceilings).
Exterior painting: Variables are wider — siding type, height, surface condition, prep requirements. Exterior square footage rates vary significantly from interior.
2. Materials
Calculate material costs from the actual surface area to be painted, not square footage of the room/structure:
- Measure the actual paintable surface (walls, ceilings, trim, doors — separately)
- Calculate the coverage for your chosen paint (typically 350-400 sq ft per gallon, less for rough surfaces)
- Add primer separately if needed
- Include all supplies: brushes, rollers, tape, drop cloths, caulk, fillers
Price materials at your actual cost, not retail. Your supplier pricing matters here.
3. Overhead
Overhead is the cost of running the business: vehicle, insurance, tools, equipment, marketing, admin time. Calculate your monthly overhead and distribute it across your estimated monthly billable hours to get an overhead cost per hour.
4. Profit Margin
After covering labor, materials, and overhead, what's left is profit. Set a target margin (10-20% is typical for painting contractors) and price accordingly.
Sample Pricing Formula
Total price = (Labor hours × labor cost/hour) + Materials + (Labor hours × overhead/hour) + Profit margin
If your job requires 24 labor hours at $45/hour labor cost, $400 in materials, $15/hour overhead, and you want 15% profit:
- Labor: 24 × $45 = $1,080
- Materials: $400
- Overhead: 24 × $15 = $360
- Subtotal: $1,840
- 15% profit: $276
- Total: $2,116
Common Pricing Mistakes
Pricing from competitor quotes: "My competitor charges X" is not a cost-based estimate. Your costs may be higher or lower. Pricing below your actual cost to match a competitor loses money on every job.
Forgetting prep: Painting contractors consistently underestimate prep time. Heavy prep (lead paint encapsulation, extensive surface repairs, power washing, extensive masking) can equal or exceed painting time.
Not accounting for re-coats: Some surfaces and colors require three coats to achieve uniform coverage. Price based on what the job actually needs, not a standard "two coat" assumption.
Building a Pricing History
Contractors who track actual time and materials on every job — versus their estimate — build accurate estimating data over time. The ones who don't keep repeating the same underestimating patterns.
With TimeFotos, job workspaces track labor time per address. Building this history improves estimating accuracy and profit on future similar jobs.

Bottom Line
Pricing painting jobs accurately requires calculating real labor cost (not just wages), measuring actual paintable surface area, tracking materials precisely, and including overhead and profit margin.
