Returns the sum of the squares of the arguments.


SUMSQ(number1,number2, ...)

Number1, number2, ...     are 1 to 30 arguments for which you want the sum of the squares. You can also use a single array or a reference to an array instead of arguments separated by commas.


  • Arguments can either be numbers or names, arrays, or references that contain numbers.
  • Numbers, logical values, and text representations of numbers that you type directly into the list of arguments are counted.
  • If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.
  • Arguments that are error values or text that cannot be translated into numbers cause errors.
