7) With the parenthesis open, select the arguments in the order of syntax. The position of the cell will be visible in the formula. According to the order of the syntax, the value of the argument must be selected followed by a comma. The change in color of the cells aids to identify the name and of the cells in the formula.

8) To conclude, close the parentheses and click enter. The cell which contains the formula will display the effective interest.
