Paint calculator uses the same method as every tool here: measure the area, add a visible allowance, divide by what one can covers, and round up. The number above is the honest planning quantity — not an exact coverage guarantee. Coverage varies with colour and surface.
paint = wall area × coats ÷ coverage × (1 + loss) → round up to whole cans
