About Paint Calculator
Paint Calculator helps homeowners and renters in the United States figure out how much paint, primer, and supplies a room needs, and what the job costs whether you do it yourself or hire a painter.
Why we built it
Planning a paint job shouldn't require handing over your phone number. We built a calculator that shows the full cost breakdown right away, with no sign-up and no personal information.
How we keep estimates accurate
- Every formula is published on the calculator page, so you can check the math.
- Price benchmarks come from published 2026 US cost guides, and we link to each source.
- You can change every rate (paint price, coverage, labor, sales tax) to match your area.
- We review prices regularly and update the "How we estimate" section when they change.
Independence
No paint brand or contractor pays to be recommended here. If we add ads or affiliate links in the future, we will label them clearly and update this page.
