🧮 What Does the Paint Per Wall Calculator Do?

This tool helps you answer the two most common painting questions:

• Estimated hours of work 
• The calculator then returns a complete breakdown:

🧠 How the Calculator Works (Formula)

Here’s how we calculate your needs:

• Wall Area = Wall Height × Wall Width 
• Total Paint Area = Wall Area × Number of Coats
• Paint Needed = Total Paint Area ÷ Paint Coverage per Unit
• Paint Cost = Paint Needed × Cost per Paint Unit
• Labor Cost = Labor Rate × Estimated Hours
• Total Cost = Paint Cost + Labor Cost 
• No guessing. No surprises.

🏠 Perfect For:

• Homeowners repainting walls or rooms
