Estimate paint gallons from wall area, openings, coats and your product’s coverage rate.
Enter your supplier’s material price. A zero price leaves cost unpriced. Example dimensions and allowances are editable.
Gallons = (length × height − openings) × coats × (1 + waste ÷ 100) ÷ coverage per gallon. Whole gallons round up.
A 30 × 10 ft wall, two coats, 350 SF per gallon and 10% waste needs 1.89 gallons. Round up to 2 whole gallons.
Enter one wall or calculate walls separately. Coverage is per coat; use the paint label’s rate. Primer, ceilings, trim and repairs are separate. Surface porosity can change consumption.
