Car Paint Calculator

Repainting a car takes more paint than most people expect — the Car Paint Calculator estimates exactly how much you'll need based on your vehicle's size and job type. Select your vehicle type (sedan, SUV, van, truck, motorcycle, or custom dimensions), then choose your number of coats, paint coverage per liter, and waste/loss rate to get your total paint required in both liters and gallons. Secondary outputs include total surface area and paint needed before waste is factored in.

Frequently Asked Questions

How is the paint usage calculated?

Our calculator uses the industry standard formula: (Total Surface Area × Number of Coats) ÷ Coverage Rate × (1 + Waste Rate). This accounts for the actual paintable surface, multiple coats, and typical material loss during application.

What is paint coverage per liter?

This is the surface area (in square meters) that one liter of your specific paint can cover with a single coat. You can find this information on the paint can label or technical data sheet. It typically ranges from 8-20 m²/L depending on the paint type.

What is the waste/loss rate and why is it important?

Waste rate accounts for paint lost during spraying, overspray, equipment cleaning, and application inefficiencies. Beginners typically waste 30%, while professionals waste around 10-20%. Including this ensures you buy enough paint.

How much paint do I need for a full car repaint?

A typical sedan requires 2-3 liters of paint for a complete repaint with 2-3 coats. Larger vehicles like SUVs and trucks need 3-4 liters. This includes primer, base coat, and clear coat if doing a full professional job.

Should I buy primer, base coat, and clear coat separately?

Yes, for best results you'll need primer (1-2 coats), base color coat (2-3 coats), and clear coat (2-3 coats). Calculate each separately as they have different coverage rates. Our calculator works for any single paint type.

What if I'm only doing touch-up work or partial panels?

For small touch-ups, use the custom dimensions option and enter the actual area you're painting. For partial panels, estimate the surface area of just those sections rather than the whole vehicle.

How accurate is this paint calculator?

This calculator provides a reliable estimate based on industry standards, but actual usage can vary based on spray gun settings, technique, surface texture, and environmental conditions. It's designed to help you purchase the right amount while avoiding waste.
