The idea of **nested magic squares** is well known in the literature, generally known by **bordered magic squares**. In this work, **nested magic squares** are studied in such a way that the magic sums are equal to the order of the magic square. The study include integer values. In some cases decimal entries with positive and negative entries are also used. The magic sums of **sub-magic squares** lead us to a general formula. The work is for the **bordered magic squares** of orders 3 to 25.
