Material and Labor Cost Estimator for Painters

Textured walls require you to reduce the standard coverage estimate of 400 square feet per gallon down to about 250 to 300 square feet per gallon. This adjustment accounts for the increased surface area created by the texture and the extra product absorbed. Always add an extra ten percent to your final paint volume calculation to ensure you do not run out mid-job.

Professional painters typically apply a markup of 15% to 30% on materials and paint to cover procurement, transportation, and handling time. This ensures you are compensated for the time spent selecting, purchasing, and transporting supplies to the job site. Passing on your contractor discount directly to the client without a markup hurts your business profitability.

For standard interior repaints, prep work should account for roughly 30% to 50% of your total estimated labor hours. If you are dealing with peeling exterior paint or damaged drywall, prep time can easily surpass application time, requiring up to 70% of the total labor budget. Always inspect the surface quality beforehand to adjust this ratio accurately.

You should calculate your internal costs using a precise hourly rate to ensure your labor is profitable, but present your client with a flat-rate bid based on the total square footage or project scope. This pricing model protects your profit margins if you work quickly while giving the client a clear, predictable price. Providing an hourly estimate to clients often leads to disputes over how fast your crew works.
