what is a subtotal

A subtotal is a sum of a part of a set of quantities or the result of adding numbers that is not the final total. In accounting, a subtotal is the sum or total of a part of a group or column of figures, as in an accounting statement. It is a figure that is the result of adding some numbers together but is not the final total. For example, if you order a few pairs of socks online, your subtotal is the cost of the socks before tax or shipping costs are added.
