SUMIF() Criteria Example

The syntax to use a criteria can vary if you want to make it depend on another cell. Here are various examples of using the SUMIF() function in Google Spreadsheets and/or Excel.

Sum cells in column B if column A = 10.
=SUMIF(A1:A10,10,B1:B10)

Sum cells in column B if column A = what's in A2.
=SUMIF(A1:A10,A2,B1:B10)

Sum cells in column B if column A > 10.
=SUMIF(A1:A10,">10",B1:B10)
=SUMIF(A1:A10,">"&10,B1:B10)

Sum cells in column B if column A > what's in A2.
=SUMIF(A1:A10,">"&A2,B1:B10)
