Creating Functions
Functions are predesigned formulas that save you the time and trouble of creating com-
monly used or complex equations. Trying to write a formula that calculates various pieces
of data, such as calculating payments for an investment over a period of time at a certain
rate, can be difficult and time-consuming. The Insert Function feature simplifies the pro-
cess by organizing Excel’s built-in formulas, called functions, into categories so they are
easy to find and use. A function defines all the necessary components (also called argu-
ments) you need to produce a specific result; all you have to do is supply the values, cell
references, and other variables. You can even combine one or more functions.
