How to Use This Painting Estimate Calculator

Getting a reliable painting estimate has never been easier. Follow these three steps to calculate the cost of your next painting project:

1. Choose Interior or Exterior

Start by selecting whether your project is inside or outside the home. Interior estimates let you add multiple rooms for a whole-house quote. Exterior estimates cover siding, stucco, brick, trim, decks, fences, and more.

2. Set Quality and Condition

Select your paint quality tier (economy, standard, or premium) and the current surface condition. These factors significantly impact both material cost and prep time, giving you a more accurate estimate.

3. Add Your Rooms or Surfaces

For interior jobs, enter each room's dimensions: length, width, and ceiling height. The calculator works out wall and ceiling area automatically. For exterior, enter measurements for each surface and stack them into one combined estimate. Hit "Get My Estimate" to see a low-to-high price range with full breakdown.

How Much Does It Cost to Paint a Room?

These ranges include paint, primer, materials, and labor. Use the calculator above to get a more tailored estimate for your specific room.

How to Estimate a Painting Job Like a Pro

Professional painters estimate jobs by measuring total paintable surface area, calculating production hours based on surface type, adding prep and cleanup time, then applying their labor rate and material markup. This calculator mirrors that exact workflow so you can quote with confidence.

Frequently Asked Questions

How much does it cost to paint a garage door?
It depends mostly on the door area, the panel style and the prep. Enter your door size and the calculator prices labor, paint, prep and supplies from it.
How do I measure a garage door for paint?
Multiply the width by the height for one face. Most people paint only the outside face; if you are painting both, double it.
Does a paneled door take longer than a flat one?
Yes. Raised panels add many more edges and cut lines than a flush door of the same size, so expect more labor than the area alone suggests.
