WHAT IS AN INTERIOR PAINTING COST CALCULATOR?

An interior painting cost calculator estimates the total price of painting rooms inside your home or commercial space. It accounts for room dimensions, number of doors and windows (which reduce paintable area), paint quality, number of coats, labor rates, and prep work to produce a realistic cost breakdown — split between materials and labor.

Whether you're a homeowner budgeting a repaint or a painting contractor building estimates, this calculator gives you a starting point built on the typical cost ranges in the benchmarks below. Contractors who quote every week can compare the apps that turn these numbers into a sent bid in our painting estimating software guide.

HOW TO USE THIS CALCULATOR

Add your rooms

Enter the length, width, and ceiling height for each room. Include door and window counts — the calculator subtracts these from paintable area.

Choose paint quality

Economy paint runs ~$25/gallon while ultra-premium can hit $90/gallon. Mid-grade ($45/gal) is the industry standard for most residential work.

Set your labor rate

Professional painters charge $35–$75/hour depending on region and experience; most suburban markets sit near the middle of that range.

For scale: the U.S. Bureau of Labor Statistics puts median pay for painters (construction and maintenance) at $23.75 an hour (May 2025). The $50 default is a billed contractor rate, which adds overhead, insurance and profit.
