How to Price a Painting Job Calculator
Enter wall area, paint cost, labor rate, and markup to get a ready-to-quote painting job price with a full line-item breakdown of materials, labor, overhead, and profit.
How this is calculated
Surface area and coat count determine how many gallons you need:
rawGallons = sqFt × coats / coverageRate. Waste is folded in
before costing — gallonsForCost = rawGallons × (1 + waste%) — so
the cost step never double-counts. Gallons to buy are ceiled to the
nearest whole gallon for display, but the float is used for cost math to avoid
step jumps at gallon boundaries.
gallonsForCost = sqFt × coats / coverageRate × (1 + waste%)
paintMatCost = gallonsForCost × $/gal
totalLaborHrs = painterHours × numPainters
laborCost = totalLaborHrs × loadedRate
overhead = per method (fixed $ | % of labor | % of direct)
directCost = materials + labor + overhead
totalCost = directCost × (1 + contingency%)
price (markup) = totalCost × (1 + markup%)
price (margin) = totalCost / (1 − margin%)Markup and margin are not the same. A 35% markup on $282 total cost gives a $381 price; the realized margin is ~25.9%. Use the pricing basis that matches how you quote — most painting contractors think in markup terms.
If the two words still blur together, the converter that runs it both ways settles which is which and markup vs margin defines each one. The same logic governs the paint itself, since the tin is a material you resell: the parts and material markup calculator is the place to set that rate deliberately.
Walls that need patching before they can be coated are priced by the sheet in the drywall pricing calculator. When the number holds, write it up on the painting estimate template, and if this is the job that turns a side line into a shop, the painting business plan template is where the year gets projected.
