The actual price depends on your location and material costs. But here is a simple way to figure it out.

To calculate an accurate bid for a 6000 sq.ft new construction home with 10 ft. ceilings and all ceilings and walls being the same color, you will need to consider several key factors for both with and without materials bids. Here is a breakdown of the steps you should take:

1. Calculate the Total Square Footage: Determine the total square footage of walls and ceilings that need to be painted in the house. For a 6000 sq.ft home with 10 ft. ceilings, the total square footage to be painted will be approximately 10,000 sq.ft (6000 sq.ft for the walls and 4000 sq.ft for the ceilings).

2. Determine Paint Coverage: The average coverage of paint varies depending on the type of paint used. Generally, one gallon of paint covers around 300-400 sq.ft. Calculate the number of gallons needed for the project based on the total square footage and the paint coverage rate.

3. Estimate Labor Costs: Calculate the labor costs based on the size of the project, the complexity of the work, and the average rate per hour for painters in your area. Consider factors such as prep work, number of coats needed, and any additional labor requirements.

4. Material Costs: Calculate the cost of materials including paint, primer, brushes, rollers, drop cloths, tape, and any other supplies needed for the project. Get quotes from suppliers to determine the total material costs.

5. Overhead and Profit Margin: Factor in overhead costs such as insurance, equipment maintenance, and administrative expenses, as well as a profit margin to ensure you are adequately compensated for your work.

6. Provide Detailed Bids: Prepare two bids – one with materials and one without materials. Outline the scope of work, including surface preparation, paint application, cleanup, and any other specific requirements. Break down the costs for materials, labor, overhead, and profit margin in each bid for transparency.
