The prices of safety deposit boxes are usually determined based on size and availability. Banks charge a yearly fee that differs depending on the branch and location.
Safety deposit boxes typically come in small, medium and large sizes. A small box is usually 12 inches long and measures 2 by 5 inches. A medium box is 12 inches long and measures 4 by 10 inches, while the largest is 22 inches long and measures 15 by 22 inches. Additional costs include replacement key fees or the cost to drill the box open in the case all sets of keys are lost.
