This article describes the formula syntax and usage of the SUMPRODUCT function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Multiplies corresponding components in the given arrays, and returns the sum of those products.
SUMPRODUCT(array1, [array2], [array3], ...)
The SUMPRODUCT function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Array1 Required. The first array argument whose components you want to multiply and then add.
- Array2, array3,... Optional. Array arguments 2 to 255 whose components you want to multiply and then add.
- The array arguments must have the same dimensions. If they do not, SUMPRODUCT returns the #VALUE! error value.
- SUMPRODUCT treats array entries that are not numeric as if they were zeros.
