Suppose you are presented with an investment opportunity. The investment is a discount security offered for sale at $685 (invest-amount), will mature on 30 June 2015 (maturity) at $1,000 (maturity-amt), and the purchase will settle on 1 May 2009 (settle). =INTRATE(“1/5/2009”, “30/6/2015”, 685, 1000, 0) returns approximately 7.46045269290106%, the effective annual interest rate of the hypothetical security. This rate could be compared to the interest rate you might earn on alternative investments as part of the decision as to which investment to make. |
