How estimates are made
Paint quantities come from surface area, coat count and user-selected coverage. Flooring quantities come from floor area, an allowance and the product’s stated box coverage. Each calculator explains its formula, sample inputs, rounding and exclusions.
Prices are yours to set
Default prices demonstrate the calculation. They are not live retail prices or average contractor rates. Replace them with a current quote. Results are estimates and cannot account for unmeasured conditions or all installation details.
Sources and editorial standards
Product guidance is linked where used. A manufacturer’s instructions apply to that product, not every material in the category. We do not claim professional inspection, independent product testing or contractor credentials.
