## Investment management functions

Use these functions to perform common calculations relating to the price and yield of bonds and the coupon periods that define when the bondholder receives interest as the bond matures.

Many of these functions rely on day count conventions to determine the number of days between two dates. Anaplan defaults to a modified version of the US 30/360 day count convention, but you may choose to use other day count conventions if you wish.

 Name Description COUPDAYBS Calculates the number of coupon days before the settlement date. COUPDAYS Returns the number of coupon days in the coupon period that contains the settlement date. COUPDAYSNC Determines the number of coupon days from the settlement date until the next coupon date. COUPNCD Calculates the next coupon date after the settlement date. COUPNUM Returns the number of coupons payable between the settlement date of a bond and the bond's maturity. Identifies the previous coupon date before the settlement date. DURATION Uses the Macaulay duration to indicate a bond price's response to changes in yield. MDURATION Uses the modified Macaulay duration to tell you by what percentage the value of a bond will change for a 1% change in the yield. PRICE Returns the price per 100 monetary units of a bond that pays periodic interest. YEARFRAC Calculates the fraction of a year between two dates. YIELD Determines the yield to maturity of a bond — the interest rate that, when used to discount the bond's future cashflows, produces the given price.
