RATE

Returns the interest rate earned per period by a security.

Syntax

RATE( terms, payment, present value[, future value, type] )

The following table describes the arguments for this command:

Argument	Required/ Optional	Description
terms	Required	Numeric. Number of periods or payments. Must be greater than 0.
payments	Required	Numeric. Payment amount due per period. Must be a negative number.
present value	Required	Numeric. Lump-sum amount that a series of future payments is worth now.
future value	Optional	Numeric. Cash balance you want to attain after the last payment. For example, the future value of a loan is 0. If you omit this argument, RATE uses 0.
types	Optional	Boolean. Timing of the payment. Enter 1 if payment is at the beginning of period. Enter 0 if payment is at the end of the period. Default is 0. If you enter a value other than 0 or 1, the PowerCenter Integration Service treats the value as 1.

Return Value

Numeric.

Example

The following expression returns 0.0077 as the monthly interest rate of a loan:

RATE( 48, -500, 20000 )

To calculate the annual interest rate of the loan, multiply 0.0077 by 12. The annual interest rate is 0.0924 or 9.24%.
