You use the SUMIF function to sum the values in a range that meet criteria that you specify.
Suppose that in a column that contains numbers you want to sum only the values that are larger than 5.
You can use the following formula:
In example above the criteria is applied to the values that are being summed.
If you want you can apply the criteria to one range and sum the corresponding values in a different range.
The formula =SUMIF(B2:B5, “John”, C2:C5) sums only the values in the range C2:C5, where the corresponding cells in the range B2:B5 equal “John.”
SUMIF (range, criteria, [sum_range])
The SUMIF function syntax has the following arguments:
The range of cells that you want evaluated by criteria. Cells in each range must be numbers or names, arrays or references that contain numbers. Blank and text values are ignored.
The criteria in the form of a number, expression, a cell reference, text or a function that defines which cells will be added. For example criteria can be expressed as 32, “>32”, B5, “32”, “apples”, or TODAY().
Any text criteria or any criteria that includes logical or mathematical symbols must be enclosed in double quotation marks (“).
If the criteria is numeric double quotation marks are not required.
The actual cells to add if you want to add cells other than those specified in the range argument.
If the sum_range argument is omitted Excel adds the cells that are specified in the range argument (the same cells to which the criteria is applied).
You can use the wildcard characters — the question mark (?) and asterisk (*) — as the criteria argument.
A question mark matches any single character.
An asterisk matches any sequence of characters.
If you want to find an actual question mark or asterisk type a tilde (~) preceding the character.
