How much should I eat to gain and then maintain weight?

I weigh 113 and I want to weigh 116. I want to gain 3 pounds. I eat 1,540 calories a day so if I eat 500 extra a day that would be one extra pound. For example, once I gain that pound, what would be my maintenance calories to stay at my new weight?:)
