1. What is the Painting Cost Calculator?

The Painting Cost Calculator estimates the total cost of painting the exterior of a house in New Zealand, including both materials (paint) and labor costs. It helps homeowners and contractors budget accurately for painting projects.

2. How Does the Calculator Work?

The calculator uses the painting cost formula:

\[ \text{Cost (NZD)} = \left( \frac{A}{C} \times \text{Price} \right) + (A \times L) \]

Where:

$ A $ — Surface area to be painted (square metres)
$ C $ — Paint coverage rate (square metres per litre)
$ Price $ — Cost of paint per litre (NZD)
