Excel SUMSQ Function

The SUMSQ function returns the sum of the squares of the values provided. You can supply values as constants, references or ranges. Values can be supplied as individual references or as ranges (as in the example shown above). SUMSQ can handle up to 255 separate arguments.

Examples

=SUMSQ(1,2) // returns 5
=SUMSQ(1,2,3) // returns 14
=SUMSQ({1,2,3}) // returns 14

In the example shown, the formula in G5, copied down, is:

=SUMSQ(B5:F5) // returns 5

Notice that SUMSQ automatically ignores empty cells and text values.

Notes

• Arguments can any mix of constants, names, arrays, or references that contain numbers.
• Empty cells, logical values, and text values are ignored when they appear in arrays or references.
• The logical values TRUE and FALSE are evaluated as 1 and 0 respectively, but only when they are hardcoded as arguments.
• Numbers entered as text (i.e. "1", "3", etc.) are evaluated, but only when they are hardcoded as arguments.
