=PRODUCT(number1, [number2], ...)

Applies to: Microsoft Office Excel 2007

This article describes the formula syntax and usage of the PRODUCT 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 Office Excel.

Description

The PRODUCT function multiplies all the numbers given as arguments and returns the product. For example, if cells A1 and A2 contain numbers, you can use the formula =PRODUCT(A1, A2) to multiply those two numbers together. You can also perform the same operation by using the multiply (*) mathematical operator; for example, =A1 * A2.

The PRODUCT function is useful when you need to multiply many cells together. For example, the formula =PRODUCT(A1:A3, C1:C3) is equivalent to =A1 * A2 * A3 * C1 * C2 * C3.

Syntax

PRODUCT(number1, [number2], ...)

The PRODUCT 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.):

number1 Required. The first number or range (range: Two or more cells on a sheet. The cells in a range can be adjacent or nonadjacent.) that you want to multiply.
number2, ... Optional. Additional numbers or ranges that you want to multiply, up to a maximum of 255 arguments.

Note If an argument is an array or reference, only numbers in the array or reference are multiplied. Empty cells, logical values, and text in the array or reference are ignored.
