When to use the paint cost tool
The paint cost calculator is built for practical painting budgets where the main question is not only how much paint to buy, but what the painter is expected to prep, protect, prime, coat, edge, clean, and include in the written price.
It is most useful when the project is still being shaped: measurements are close but not final, product grades are not fully selected, and the homeowner wants a clearer brief before comparing suppliers, materials, service companies, or contractor quotes.
