Estimate the total cost of a painting project including paint, primer, supplies, and labor. Enter gallons needed and prices for a full budget breakdown.
Budgeting for a painting project involves more than just the cost of paint. You need primer, brushes, rollers, tape, drop cloths, and possibly a sprayer rental. If you're hiring professionals, labor often represents 70–85% of the total cost. Understanding all these cost components helps you plan a realistic budget and decide between DIY and professional painting.
This paint cost calculator breaks down the full expense of your project. Enter the gallons of paint needed, the price per gallon, primer costs, supply costs, and optional labor. The calculator provides a comprehensive cost breakdown so you can compare options and plan your budget with confidence.
Whether you're painting a single accent wall or an entire house exterior, starting with a clear cost estimate helps prevent budget surprises and lets you allocate funds appropriately across all the materials and labor involved.
Understanding this metric in quantitative terms allows construction professionals to compare design alternatives, evaluate cost-effectiveness, and select the optimal approach for each project.
Paint prices vary dramatically by brand and quality, from $20 to $80+ per gallon. When combined with primer, supplies, and potential labor costs, a painting project can add up quickly. This calculator provides a complete cost picture so you can make informed decisions about product quality and DIY vs. professional work.
Paint Cost = Gallons × Price per Gallon Primer Cost = Primer Gallons × Primer Price per Gallon Total = Paint Cost + Primer Cost + Supply Cost + Labor Cost
Result: $615.00
Paint: 10 gal × $45 = $450. Primer: 3 gal × $30 = $90. Supplies: $75 for brushes, rollers, tape, and drop cloths. Total: $450 + $90 + $75 = $615 for a DIY project.
Every painting project has four main cost components: paint, primer, supplies, and labor (if not DIY). Paint is typically 15–30% of a professional job's total cost, with labor making up the remaining 70–85%.
Budget paints ($15–$25/gal) have lower solids content and may need 3+ coats. Mid-range paints ($30–$45/gal) offer good coverage in 2 coats. Premium paints ($50–$75/gal) often achieve excellent coverage in 1–2 coats with superior durability and washability.
DIY painting is best for simple rooms with standard ceilings and minimal prep work. Hire professionals for high/vaulted ceilings, extensive repair work, exterior painting, or when time is a constraint. The quality difference between skilled and unskilled painting is significant.
Do your own prep work (cleaning, sanding, taping) even if hiring painters for the actual painting. Buy paint during holiday sales for 25–40% off. Use paint-and-primer combos to reduce the number of coats. And always get three quotes from professional painters before committing.
A typical bedroom costs $100–$300 for DIY (paint and supplies) or $300–$800 for professional painting. The exact cost depends on room size, paint quality, number of coats, and local labor rates.
Professional painters charge $2–$6 per square foot of wall area, which translates to about $200–$800 per room. Whole-house interior painting for a 2,000 sq ft home typically costs $3,000–$7,000 including labor and materials.
Generally yes. Premium paints ($40–$70/gal) have higher pigment concentration, better coverage (sometimes 1 coat is sufficient), more durability, and longer lifespan. Cheap paint may cost less per gallon but require more coats and more frequent repainting.
Basic supplies include: roller frame and covers, paint tray, painter's tape (1–2 rolls per room), drop cloths, angled brush (for cutting in), stir sticks, and a paint can opener. Add sandpaper, spackle, and caulk for prep work.
Exterior painting typically costs $1,500–$5,000 for a single-story home and $3,000–$10,000 for a two-story home when professionally done. DIY exterior painting costs $200–$600 in materials for a typical home.
DIY saves 60–75% on cost but requires your time (a room takes 4–8 hours). Professionals deliver faster, more uniform results and can handle difficult areas like high ceilings, stairwells, and exteriors more safely.
Primer typically covers 300–400 sq ft per gallon. You need primer for new drywall, stains, bare wood, and dramatic color changes. On previously painted walls in good condition with a similar color, you can usually skip primer.
Most professional painting quotes include both labor and materials. Some painters offer a labor-only rate allowing you to provide the paint. Ask for an itemized quote to see the breakdown.
