What the result includes
A preliminary low-to-high planning range, estimated worker-hours, finish-paint gallons, and measured scope.
Free planning tool
Free Interior Painting Cost Estimator for U.S. Projects
Estimate interior painting costs, finish-paint quantity, labor hours, and a state-adjusted planning range anywhere in the United States. LMJ can receive inquiries from any state when the property to be painted is within Tampa Bay or another approved Florida service area.
GuideOptional · RecommendedHow to measure your rooms
1. Choose a room
Start with one room or work area.
2. Measure the room
Use a tape or laser. Enter the length, width and height. Measure unusual wall sections separately.
3. Add painting details
Count doors and windows. Choose what will be painted and who will supply the paint and materials.
4. Check your answers
Fix anything marked missing, then show your preliminary result. LMJ will confirm the final scope and price.
No measuring tool? Walking the room only gives a rough guess. Mark it as approximate and measure again with a tape or laser before requesting a written quote.
Remember: The paint amount is an estimate. The paint label and the condition of the walls may change how much is needed.
Stay safe: Do not climb or enter an unsafe area. Tell LMJ about hard-to-reach areas and buildings built before 1978.
Guidance checked against NIST measurement guidance, manufacturer coverage guidance, and EPA lead-safe requirements.

Actions before work
- •Protect floors and furniture; verify surfaces are clean and dry.
Materials to confirm
- •LMJ: include finish paint, preparation materials, other supplies in the purchasing and load-out plan.
- •Confirm finish-paint coverage; the current planning quantity is 5.0 finish gallons.
Walkthrough checks
- •Confirm final colors, sheen and surfaces during the walkthrough.
- •Verify doors, windows, ceilings and trim included in the scope.
- •Ask whether the home was built before 1978 before disturbing existing coatings.

These references explain the assumptions and important safety considerations.
Official state price adjustment
The state selector uses the U.S. Bureau of Economic Analysis 2024 Regional Price Parity for each state and Washington, D.C. Local market conditions still vary.
Painter labor benchmark
The labor model is checked against U.S. Bureau of Labor Statistics painter wage and employer-cost data; contractor prices also include overhead, risk and profit.
Paint quantity guidance
Sherwin-Williams says a gallon typically covers about 350–400 square feet. Product labels and surface texture still control actual coverage.
Lead-safe planning
EPA warns that disturbing paint in pre-1978 homes may create dangerous lead dust and recommends lead-safe work practices.
Indoor air and ventilation
EPA recommends fresh air and ventilation when painting and following every product label and warning.

Estimate interior painting costs anywhere in the United States
Use room or wall-by-wall measurements for homes, rentals, offices, retail spaces, cabinets, ceilings, trim, doors, and windows. The estimator separates measured paintable area, finish coats, preparation, painted openings, materials, and state-level market adjustment.
Why location matters
Labor, materials, access, demand, and operating costs vary by state and city. Select the project state before reviewing the range.
Before hiring a painter
Confirm surface condition, repairs, product specifications, colors, access, taxes, and the final written scope with a qualified local contractor.
Estimate and service limits: This is a non-binding planning estimate, not a guaranteed national price, offer, appraisal, or contractor bid. The state adjustment uses BEA 2024 state price levels; it does not independently calculate city labor, sales or use tax, permits, licensing, insurance, repairs, hazardous-material work, or legally required contract terms. Confirm those items and a written scope with a properly qualified local provider. LMJ may receive a request from any state, but direct painting work is reviewed according to the Florida location of the property and LMJ's approved service area.
Purchasing: A result pass purchases access to an additional calculation only. It does not authorize painting work or lock in the displayed estimate. The checkout must show the seller, total price, applicable taxes, payment timing, and any cancellation or refund terms before payment is confirmed. Consumer and contractor requirements vary by state and locality.
