That's like asking how much for stuff, it's a pretty broad question. Do you need interior or exterior? Quality? Color? A gallon of Glidden interior semi-gloss white is about $22. A 5 gallon Behr Premium elastomeric is about $130. It really depends on what your painting.

It depends on many different things. Paint options can range anywhere from $15-20 a gallon to upwards of $50-60 a gallon. Depending on paint type and color options.
