DURATION(settlement, maturity, coupon, yield, frequency, basis)
- Where 'settlement' is the security's settlement date (a date when coupon or a bond is purchased),
- 'maturity' is the security's maturity date (a date when coupon or a bond expires),
- 'coupon' is the security's annual coupon rate,
- 'yield' is the security's annual yield,
- 'frequency' is the number of coupon payments per year, and
- 'basis' is the type of day count basis to use.
DURATION() gives the Macauley duration of a security for an assumed par value of $100.
Description
DURATION(settlement, maturity, coupon, yield, frequency, basis)
- If settlement or maturity dates are not valid, Calci displays an error message.
- If settlement date ≥ maturity date, Calci displays an error message.
- 'coupon' and 'yield' values must be greater than or equal to zero.
- The values for 'frequency' should be 1,2 or 4.
For Annual payment, frequency = 1,
For Semi-annual payment, frequency = 2,
For Quarterly payment, frequency = 4.
- 'basis' value is optional. If omitted, Calci assumes to be 0.
Below table shows the use of 'basis' values:
