YIELDDISC(settlement, maturity, price, redemption, basis)

where $settlement$ is security's settlement date (a date when coupon or a bond is purchased),
$maturity$ is security's maturity date (a date when coupon or a bond expires),
$price$ is the price per $100 face value,
$redemption$ is security's redemption value per $100 face value,
$basis$ is the type of day count basis to use.

YIELDDISC() calculates the annual yield on discounted security or a bond.

Description

YIELDDISC referred to as 'Discount Yield' is the measure of security's percentage return.

Formula:-

 $DiscountYield={\frac {(parvalue-price)}{parvalue}}*{\frac {360}{daystomaturity}}$

$settlement$ and $maturity$ dates should be entered either in 'date format' or 'dates returned using formulas'. If dates are not valid, Calci displays #N/A error message.
If $settlement$ date = $maturity$ date, Calci displays #N/A error message.
$price$ and $redemption$ values must be greater than zero, else Calci displays #N/A error message.
$basis$ value is optional. If omitted, Calci assumes it to be 0.

Below table shows the use of $basis$ values:

Basis	Description
0	US (NASD) 30/360
1	Actual/actual
2	Actual/360
3	Actual/365
4	European 30/360

If $basis$ value is other than 0 to 4, Calci displays #N/A error message.

Examples

YIELDDISC(settlement, maturity, price, redemption, basis) function with inputs in order is calculated as follows:

1/1/2008
20/2/2008
95.58
100
2

=YIELDDISC(A1,A2,A3,A4,A5) : Calculates the discount yield Value with the inputs in the range A1 to A5. Returns 33.3% as a result.
=YIELDDISC(DATE(2007,1,1), DATE(2008,2,20), 85.12, 100) : Calculates the discount yield Value with the inputs. Returns 15.39% as a result.
