Common questions

How much does it cost to paint the interior of a house?

Our reviewed national dataset gives a planning range of $2.00 to $6.00 per square foot of paintable wall area, with a typical figure of $2.75. A 12 by 12 foot bedroom with roughly 400 square feet of wall area lands near $1,100 at the typical rate.

What does the typical cost include?

Labor and paint for walls in standard condition. Surface preparation such as sanding and patching adds $0.50 to $0.75 per square foot in our dataset, and the calculator folds that allowance into the range when you select it.

Why is the cost range so wide?

Wall condition, paint quality, the number of coats, and extras like ceilings, trim, and moving furniture all move the price. Homes that need heavy preparation land near the high end of the range.

Does this estimate include ceilings and trim?

No. The dataset covers wall painting only. Ceilings, trim, doors, and closets are usually quoted as add-ons by painters.

Is this a quote I can hand to a painter?

No. It is a national planning range for budgeting. Local labor rates vary, so collect two or three local quotes before committing to a contractor.
