ACCRINT calculates the accrued interest for a security that pays periodic interest. The @rate is the annual rate of the security and @par is the par value of the security. @basis is the type of day counting system you want to use:
0 US 30/360
1 actual days/actual days
2 actual days/360
3 actual days/365
4 European 30/360
If @basis is omitted, US 30/360 is applied. If @issue date or @settlement date is not valid, ACCRINT returns #NUM! error. If @rate or @par is zero or negative, ACCRINT returns #NUM! error. If @basis < 0 or @basis > 4, ACCRINT returns #NUM! error. If @issue date is after @settlement date or they are the same, ACCRINT returns #NUM! error.
