Use this free paint cost calculator to build a transparent project budget from the scope and current local rates you enter.
HomeCalc keeps the main cost assumptions editable so you can replace defaults with contractor quotes, supplier prices, permit fees and other figures that apply where you live.
Paint material cost is the paint quantity multiplied by the unit price. HomeCalc first works out gallons from area, coats, coverage and allowance, then applies the price per gallon so changes in coverage or coat count are reflected in cost.

Estimate paint cost from quantity, not price alone
Paint material cost is the paint quantity multiplied by the unit price. HomeCalc first works out gallons from area, coats, coverage and allowance, then applies the price per gallon so changes in coverage or coat count are reflected in cost.
area × coats × allowance ÷ coverage × price per gallon = cost
What to check before using the estimate
- Enter the real shelf or quoted price for the product you plan to buy.
- Use that product's coverage rather than a universal value.
- The result is paint-material cost only unless other supplies are explicitly included.
- Whole-can purchasing can make the checkout total higher than a fractional-gallon mathematical cost.
A cheaper paint that needs more material or more coats may not produce the lowest project cost. Quantity and price need to be evaluated together, which is why the calculator includes both.
