Model your painting business profit by entering weekly job volume, average job value, materials percentage, and fixed monthly costs — then see profit per job.
Paint and primer cost 25% of each job's billing — or 35%, if you have been estimating loosely. That 10-point gap on 17 jobs per month is $2,365 in profit you thought you had but did not. Materials, labor, vehicle, overhead, and marketing subtract from gross revenue to give you net profit, and the materials percentage is the lever operators most often measure wrong.
This calculator uses Jobs Per Week, Working Weeks Per Month, Average Job Value, and a Materials/Parts Cost percentage, then adds Monthly Labor Cost, Monthly Vehicle/Fuel, Monthly Overhead, and Monthly Marketing as fixed amounts. The result is monthly gross revenue, total expenses broken down by category, net profit, and profit per job. Run your current numbers first, then test what a $200 increase in average job value does to the bottom line.
Materials cost: the margin variable most painting owners estimate loosely
Paint and primer costs vary from $15 to $80 per gallon depending on brand, finish, and coverage application. A two-room interior job using two gallons of primer and four gallons of finish paint might have $120–$280 in materials depending on product quality. On a $1,375 average job, 25% materials is $344 in paint, tape, drop cloths, and brushes — realistic for a mid-tier residential painter using quality products.
The danger is running materials cost at 25% when it is actually 35% because of waste, damaged materials, or using premium products on jobs quoted for mid-grade. A 10-point gap in materials cost on $23,650 monthly gross revenue is $2,365 per month in profit you thought you had but did not. The calculator makes the materials percentage explicit so you compare your estimate to your actual supply receipts and find the gap.
Labor cost structure for a painting business
Monthly Labor Cost in the tool is the flat amount you pay employees or subcontractors per month, regardless of job volume. A solo operator with no employees enters zero here and captures their own income as the residual net profit. An owner with two full-time painters on payroll at $22/hour for 160 hours each pays roughly $7,040 in labor per month before payroll taxes.
Owner-operators often make the mistake of not counting their own labor as a cost. If you are on the jobsite 25 hours per week and not accounting for that time in the cost model, your net profit figure is artificially high. Load your own effective hourly rate into labor cost if you work jobs alongside employees — the realistic model assumes the business pays you for your time regardless of whether you draw a formal salary.
Average job value: the fastest lever for painting business profitability
At 17 jobs per month (4 per week times 4.3 weeks) with a $1,375 average, gross revenue is $23,375. At the same job count with a $1,600 average, gross is $27,200. The difference is $3,825 per month in additional revenue with no increase in jobs, labor, or overhead. That is what one $225 average job value increase is worth — and it comes entirely from pricing.
Painting pricing is driven by scope, substrate condition, paint quality, and market rates. Most markets have wide range between the cheapest contractor and the best. Positioning yourself on quality differentiation, prep work standards, and warranty allows higher average job values without losing the clients you want. The calculator quantifies the revenue impact of any pricing change before you implement it.
Vehicle and fuel: the overhead item that scales with volume
Monthly Vehicle/Fuel covers all costs of operating your truck or van for the business: fuel, oil changes, tires, commercial auto insurance, and any lease or loan payments. For a single-vehicle painting operation, this commonly runs $300–$600 per month. For a multi-truck operation, multiply proportionally. Vehicle cost is semi-variable: it grows with job volume but not linearly, because fuel scales with jobs while insurance and maintenance are more fixed.
The tool tracks vehicle cost separately from general overhead because it is the cost center most painting owners lump into a vague 'expenses' bucket. Isolating it lets you see what portion of each job's revenue goes to vehicle operations. On a $1,375 job at 17 monthly jobs, a $350 vehicle cost is $20.59 per job — a small but real cost that belongs in your job costing estimate, not just in your annual tax return.
How to use it
- Enter Jobs Per Week and Working Weeks Per Month to set your baseline job volume for the month.
- Set Average Job Value to your actual average across residential and commercial jobs — weighted by which type makes up most of your volume.
- Drag the Materials/Parts Cost slider to your real materials cost as a percentage of job revenue.
- Enter Monthly Labor Cost, Monthly Vehicle/Fuel, Monthly Overhead, and Monthly Marketing as flat dollar amounts.
- Read Net Profit and Profit Per Job, then test job value changes or labor additions to plan for next quarter.
Who it's for
- Solo painter considering first hire — Currently netting $5,200 per month at 4 jobs per week, models adding a helper at $2,800 monthly labor and increasing to 6 jobs per week, and checks whether the additional net profit justifies the hire.
- Painting company evaluating commercial work — Has mostly residential jobs at $1,200 average, models shifting to commercial jobs at $3,500 average with fewer but larger jobs, and compares the net profit at different volume levels.
- Owner pressure-testing materials cost estimate — Has been estimating 20% materials cost, pulls last month's supply receipts, finds actual cost is 28%, and recalculates net profit to understand the true margin before repricing.
- Contractor planning spring expansion — Models ramping from 4 to 7 jobs per week in April, accounts for higher vehicle fuel and a seasonal helper, and checks whether the revenue increase covers the new seasonal costs.
Key terms
- Average job value
- The mean revenue generated per completed job across all project types. The primary pricing lever for a painting business — small increases compound significantly across monthly job volume.
- Materials cost percentage
- Paint, primer, tape, drop cloths, and applicator consumables expressed as a share of job revenue. Typically 20–35% for residential painting; higher for specialty coatings or premium product work.
- Profit per job
- Net monthly profit divided by total monthly jobs. Tells you what each job contributes after fixed costs are covered — the number to watch when evaluating whether to take on smaller or marginal jobs.
- Job costing
- The practice of tracking actual materials, labor, and direct costs per individual job to compare to the quoted price. Accurate job costing over time is how painters discover whether their pricing covers real costs.
Frequently asked questions
What is a realistic average job value for a painting business?
Residential interior room jobs commonly run $400–$800 per room in most markets. Full interior house painting for a typical 1,500–2,000 square foot home often runs $2,500–$5,000. Exterior house painting for the same size home commonly runs $3,000–$7,000 depending on siding type and prep requirements. A blended average of $1,200–$1,800 is common for small-to-mid painting businesses with a mix of project sizes.
Should I include touch-up and callback work in job count?
Only if those generate separate revenue. Warranty touch-ups are a cost, not revenue — if you are returning to fix something at no charge, that job should show up in your overhead or labor cost as an uncompensated day, not as an additional job in the revenue model.
What is a reasonable net margin target for a painting business?
Solo operators or owner-operators who work jobs themselves typically run 30–50% net margin after accounting for their own labor. Multi-crew painting companies with employee payroll more commonly run 15–30% net margin. The difference is the cost of employee labor relative to the markup applied to their time.
How should I handle jobs that span multiple weeks?
Average your multi-week commercial or large residential jobs across the weeks they run. If a $8,000 job takes two weeks, count it as two $4,000 weekly job entries or a single $8,000 average distributed across the month. The goal is an accurate monthly average, not a perfectly precise job-by-job accounting. Plug your real numbers in here — seeing profit per job for the first time is usually the moment painters realize their pricing needs to move up.
