Get an instant cost estimate for your painting project. Our calculator provides estimates adjusted for your state using regional cost indices.
Why this calculator
I built these calculators after years of watching homeowners get blindsided by quotes that had no relation to real regional pricing. The model pulls from contractor bid data, BLS labor rates, and state-specific construction cost indices so the estimate you get reflects what your neighbors are actually paying, not a national average. Get 3+ licensed quotes to confirm.
Tip: Multiply room perimeter x ceiling height for each room
Bloggers, realtors, contractors, and publishers: copy one line of code and give your readers a state-adjusted paintingcost estimate. Auto-updates — no maintenance needed.
Our painting calculator estimates costs based on total wall area, number of coats, surface prep requirements (scraping, priming, patching), and paint quality tier. Interior and exterior projects use different labor rate models reflecting the specialized equipment and safety requirements of exterior work.
We show you a range (low, average, high) because actual costs depend on contractor pricing, material brands, project complexity, and local market conditions. Our data covers all 50 states and is updated quarterly. For the most accurate estimate, we always recommend getting 3+ quotes from licensed local contractors.
One gallon covers approximately 350 sq ft with one coat. Most projects need 2 coats, so divide your wall area by 175 to get gallons needed. Our calculator factors this in automatically.
Professional painters charge $2.50-$5.00 per sq ft for interior work. DIY saves 60-70% but takes 3-4x longer. Pros deliver better results on ceilings, trim, and cut-in work. DIY is great for single rooms; hire a pro for whole-house projects.
Yes. Premium paint ($50-$65/gallon) has better coverage (fewer coats needed), lasts longer, and has more durable finishes than builder-grade ($25/gallon). The paint cost difference on a typical room is only $50-$100, but the result lasts years longer.
No. Interior and exterior painting never requires a building permit. It is purely cosmetic work.
Interior: 5-10 years depending on traffic and quality. Exterior: 5-7 years for standard paint, 7-10 years for premium. Darker colors fade faster on exteriors.
