Sum if cells are equal to

Explanation 

To sum numbers based on cells being equal to a certain value, you can use either the SUMIF or SUMIFS functions. In the example shown, we are summing all sales in the West region. The formula in cell H6 is:

=SUMIF(region,"West",amount)

The formula in cell H7 is:

=SUMIFS(amount,region,"West")

Both formulas refer to the named ranges "region" (C5:C30) and "amount" (E5:E30).

How these formulas work

Both formulas use built-in functions to calculate a subtotal, but the syntax used by SUMIF and SUMIFS is slightly different:

SUMIF(range,criteria,sum_range)
SUMIFS(sum_range,range,criteria)

In both cases, note that the region "West" must be enclosed in double quotes, since it is a text value.
