There is a formula used to calculate how much paint you need to paint a room. Determine what the square feet of the room you are painting is and multiply it by the number of coats you want to put on the walls. Divide that number by 400 and you will end up with the number of gallons of paint you need. The other choice is to use an online paint calculator.

You will probably find that you will need at least 2 gallons of paint to cover the room well. If you need to prime the walls first then that will add to your cost. I would suggest that roughly 100 dollars should cover it.
