In this video I demonstrate three methods for summing across multiple columns with one or more criteria. This can't be done using the SUMIF or SUMIFS functions as the sum range has to be the same size as the criteria range(s), that is unless you add a total column and use this as the sum range. If you don't want to or can't add a total column you can either use SUMPRODUCT or SUM and FILTER combined.
