Frequently Asked Questions
Does this estimate include the cost of paint?
Generally, a rate of $1.50 to $2.00 per square foot covers basic labor and standard materials. However, if the homeowner requests premium paint brands (like Sherwin-Williams Emerald), you should increase your rate on the interior house painting cost calculator to $2.50+ to protect your profit margins.
How do I price trim, doors, and ceilings?
Trim and ceilings take significantly more prep time and careful cutting-in. Always switch the tool to the "Walls + Trim" mode, which bumps the recommended rate to account for the tedious brushwork required.
