COUPDAYS(settlement, maturity, 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),
• $frequency$ is the number of coupon payments per year, and

Description

COUPDAYS(settlement, maturity, frequency, basis)

• COUPDAYS() calculates the number of days between the coupon dates surrounding the settlement date.
• $settlement$ 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.
• 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 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.
