Part II: Using Functions in Your Formulas
Summing values based on a text comparison
The following formula returns the total invoice amounts for the Oregon office:
=SUMIF(Office,”=Oregon”,Amount)
Using the equal sign is optional. The following formula has the same result:
=SUMIF(Office,”Oregon”,Amount)
To sum the invoice amounts for all offices except Oregon, use this formula:
=SUMIF(Office,”Oregon”,Amount)
Text comparisons are not case-sensitive.
Summing values based on a date comparison
The following formula returns the total invoice amounts that have a due date after May 1, 2010:
=SUMIF(DateDue,”>=”&DATE(2010,5,1),Amount)
Notice that the second argument for the SUMIF function is an expression. The expression uses
the DATE function, which returns a date. Also, the comparison operator, enclosed in quotation
marks, is concatenated (using the & operator) with the result of the DATE function.
The formula that follows returns the total invoice amounts that have a future due date (including
today):
=SUMIF(DateDue,”>=”&TODAY(),Amount)
Conditional Sums Using Multiple Criteria
The examples in the preceding section all use a single comparison criterion. The examples in this
section involve summing cells based on multiple criteria.
Figure 7-16 shows the sample worksheet again, for your reference. The worksheet also shows the
result of several formulas that demonstrate summing by using multiple criteria.
